Growing populations and rapid economic growth influence India’s rising energy consumption. India’s third-highest consumer of final energy is the road transport industry, which is virtually entirely dependent on petroleum oil. Nearly one-fifth of the nation’s import expenditure—more than four out of every five percent of crude petroleum—comes from imports. In 2018, India contributed around 7% of the world’s energy-related CO2 emissions, of which the transport industry was responsible for 13%. Alternative fuels have been researching in India for approximately 20 years to decarbonize the road transportation industry and solve energy security, efficiency, and air quality difficulties. 

Electricity and biofuels can provide significant prospects for the near-term decarbonization of the road transportation industry. Hydrogen and compressed natural gas both have the potential to be essential players in this area throughout the short, medium, and long term.

Options and current situation for transportation’s alternative fuels

Alternative fuels, including biofuels (ethanol and biodiesel), CNG, methanol, electricity, hydrogen, etc., have been considering for development and use in India among the various choices. The Government of India (GoI)’s “Auto Fuel Policy, 2003” made several recommendations, including the use of CNG/LPG in cities with higher vehicular penetration, accelerating the development of battery electric, hydrogen, and fuel cell vehicles (FCV), and developing sustainable biofuel production technologies based on locally available resources as well as vehicles for their use.

Recent changes in the power mix of India, the evolution of shared mobility solutions that maximize the use of expensive transportation assets, and improvements in battery chemistries have all contributed to the favourable environment for the growth and adoption of electric mobility. The following sections contain information on the governmental actions implemented, particularly in India, to promote the development of various alternative fuels for use in road transportation and the advancements made compared to international successes.

Biofuels

Ethanol and biodiesel are the two main liquid biofuels produced and used worldwide. While corn, sugar cane, and other crops are primarily using to make ethanol, animal and vegetable oils, including used cooking oil (UCO) from kitchens, are using to make biodiesel. In addition, the production of hydro-treated vegetable oil (HVO) and hydro-treated esters and fatty acids (HEFA) from the same feedstocks used to make biodiesel for use as a diesel alternative is growing. Additionally, it anticipates that between 2023 and 2025, the average global biofuel production will increase to 182 BL.

Development in India

The GoI mandated the usage of exclusively non-edible oilseeds for biodiesel production to stop the gap between the demand and supply for edible vegetable oil in the nation from getting even more comprehensive. By adding ” additional states to the program in 2006, the requirement for the provision of E5 was expanding to a broader geographic spread of the nation. Due to the scarcity of ethanol, India experienced difficulties with its biofuel initiative, much like many other nations worldwide. India’s National Policy on Biofuels, enacted in 2009, permits the purchase of ethanol made from non-food feedstocks such as molasses, cellulose, and lignocellulose materials. By the end of 2017, the plan is to achieve the aim of 20% ethanol and biodiesel admixing in gasoline and diesel, respectively.

Compressed natural gas

In its compressed form, known as CNG is another form of alternative fuel. Natural gas mainly consists of methane, may be utilized in three-wheeled auto-rickshaws, vehicles, and municipal buses, and CNG pressure might be increased to 250 bar. The usage of CNG as an automotive fuel has advanced, and it is currently prevalent in many nations. CNG provides advantages over other fossil fuels in decreased CO, CO2, NOx, and particulate matter 

 emissions. Its widespread availability, compatibility with spark ignition (SI) and compression ignition (CI) engines, and inexpensive operating costs influence its acceptance. 

As of December 31, 2019, over 28.54 million CNG-powered cars were operating worldwide, refuelling at 33,383 stations in more than 85 nations. According to the highest percentage of CNG-fueled automobiles, China, Iran, India, Pakistan, and Argentina are the top five nations. 

Development in India

The adoption of a sizable number of CNG cars in India was possible by the local capability to make NG vehicles. The GoI’s favourable policy framework has also made it easier for people to acquire CNG automobiles. As of March 31, 2020, these initiatives have resulted in a combined stock of around 3.38 million CNG-fueled cars and the construction of 2207 CNG refuelling stations throughout 20 Indian states and four centrally managed territories. During 2019–20, these vehicles accounted for about 6.7% of all NG consumption. By 2030, 33 million CNG-powered cars and 10,000 CNG refuelling stations will be in India. Including imported LNG (33,680 MMSCM), India consumed 63,932 M metric standard cubic meters (MMSCM) of NG in 2019–20 

Compressed Biogas

The anaerobic digestion of various wastes/biomass resources from agricultural, dairy, municipal sewage treatment facilities, solid waste from cities, etc., can result in the purified and compressed form of compact biogas (CBG). CBG is another alternative fuel for achieving dercarbonisation. It then mixes with NG or CNG or used as a CNG or LNG replacement to lessen reliance on imports. Regarding composition, energy content, and other characteristics, CBG is comparable to commercial NG and has a methane proportion above 0.95. India can produce 62 MTA of CBG from a variety of resources. 5,000 CBG system expects to install nationwide in stages by 2025 under the GoI SATAT program, which began in 2018. These systema anticipates to produce 15 MTA of CBG or around about 30% of NG consumption of 48.65 MTA in the country during 2019–20

Liquefied Petroleum Gas(LPG)

LPG, a propane and butane combination commonly referred to as “autogas” in some countries, may also used as a transportation fuel when not mixed. It is a fuel with comparatively low carbon emissions. Auto LPG is the world’s third most used automobile fuel, powering more than 27 million cars. Additionally, it is cost-effective for the user and extends engine life while lowering maintenance costs. With roughly 71,000 dispensing outlets, over 70 countries is using auto LPG.

Development in India

The Auto Fuel Policy, 2003 of the GoI proposed, among other measures, the use of these gaseous fuels in cities with a more significant population of automobiles after realizing the advantages associated with alternative fuels such as CNG and LPG. Additionally, in 2014, the GoI released the Auto Fuel Vision and Policy 2025, which provided a roadmap for a swift transition to the new emission standards specified in BS-IV throughout India.

Despite offering the user economic benefits and being more environmentally friendly than gasoline and diesel, auto LPG has only achieved limited success in India due to unfavourable policy frameworks for its expansion. Additionally, few auto LPG vehicles are made in Indi. And retrofitting auto LPG kits is preferred because this market is unregulated. 

Methanol

Resources, including coal, NG, and biomass that can create syngas, is using to make methanol. Methanol is an efficient fuel that emits less NOx and PM pollutants than gasoline and no SOx emissions because it contains no Sulphur. For usage as an automobile fuel, it then combines with gas or used as a complete replacement. Methanol, however, is more corrosive than gasoline, may require significant infrastructure improvements for its storage and delivery, and is extremely dangerous to people if eaten. 2019 saw an estimated 98.281 MT of methanol produced globally. In which 19.777 MT was utilizing as an alternative fuel for blending with gasoline and combustion, manufacturing of biodiesel and dimethyl ether, and in fuel cells.

Development in India

India is still in the early stages of methanol production; in 2018–19, domestic production was just approximately 0.27 MT, compared to the installed production capacity of 0.47 MT. In 2019, it imported 2.3 MT of methanol. The majority of Indian methanol production now relies on imported NG. Thus, the country may use its substantial coal deposits to produce methanol to blend with gasoline or completely replace it. The ability to produce methanol might be increased using biomass, stranded gas, and high-ash coal from India. Coal India Ltd. is now putting up a factory using coal to produce 0.676 MT of methanol. In Assam, a trial program for cooking using canister-based methanol started in 2018. 

Electricity for transportation

The two primary elements of the modern energy system are electricity and liquid fossil fuels, with electricity supplying very dense energy globally for various uses, including lighting, propulsion, refrigeration, communication, and computation. Electricity is a very efficient and clean energy source after the generating stage. Over 90% of electricity is using efficiently in motors to produce rotary motion for various everyday applications. Because of these characteristics, electricity is a crucial energy vector for movement.

The introduction of ICE-based cars and a lack of adequate infrastructure for power distribution and battery recharging, including the time required for recharging, were some of the causes that led to the end of the first golden era of EVs. In the past ten years, interest in EVs has once again risen due to concerns about vehicular emissions, climate change, and energy security being brought to the attention of policymakers and automakers. While the switch to electric mobility is still in its early stages in some nations, the adoption of EVs is accelerating in some of the world’s largest markets for personal vehicles due to falling battery prices and expanding EV charging infrastructure. Of different kinds, including cars, buses, taxis and shared vehicles, light commercial vehicles (LCV), two/three-wheelers and heavy-duty vehicles with short-range requirements such as urban deliveries.

Development in India

When Bharat Heavy Electricals Ltd hired to build an “Electra van” with 18 seats for usage in Delhi and other major cities, the introduction of electric mobility in India officially began in the early 1980s. About 200 of these vehicles developed and put on display. Eddy Current Control (India) Ltd. created the first electric vehicle in India in 1993. After that, electric three-wheelers/rickshaws, e-bikes, and a tiny electric automobile (Reva) get developed and used in 1996.

The National Electric Mobility Mission Plan (NMEPP) 2020 was created in 2012, and the Ministry of Heavy Industries and Public Enterprises, Government of India, launched the first phase of Faster Adoption and Manufacturing of (Hybrid &) Electric Vehicles (FAMHEV) in 2015 [80], [81]. With a budget of US$ 140.7 million, Phase-I of FAMHEV (also known as FAME-I in India) carried out from April 2015 to March 2019. Following that, FAMHEV-II (or FAME – II) launched in April 2019 for three years with a total allocation of US$ 135.86 million to promote e-2 Wheelers, e-3 Wheelers, e-4 Wheelers, 4W vigorous hybrids, and e-buses as well as the establishment of charging infrastructure. The amount of financial support for EVs depends on the battery’s capacity.

Hydrogen

In light of its potential to play a significant role in decarbonizing the transportation, industrial, and household sectors and thereby offering solutions to climate change-related issues with which the entire world has been grappling in recent years, hydrogen has been attracting a lot of attention from policymakers, environmentalists, researchers, automobile companies, and others. The most prevalent and lightest element in nature is hydrogen. Among all available fuels, hydrogen has the highest gravimetric energy content (120.7 MJ/kg), 2.7 times more calorific than gasoline. Additionally, it is environmentally friendly because it only emits water vapour when it is being used. Hydrogen has a lengthy history of use in energy-related applications.

Since 1975, the demand for pure hydrogen increased more than three times and predicted to reach more than 70 MT in 2018. Because it can lower GHG emissions, provide energy independence, and enhance the ambient air quality in the areas that choose to use it. Whereas Hydrogen is seen as an appealing energy source for vehicular applications.

Development in India

Since about 30 years ago, the Government of India has supported a wide range of R&D activities in the nation, realizing the significance of hydrogen for supplying the energy needs of the transportation sector and for distributed power generation. The Ministry of New and Renewable Energy (MNRE), GoI, created a National Hydrogen Energy Roadmap (NHER) in 2006, intending to accelerate the research and commercialization of hydrogen-based technologies in India. NHER focused on projects based on public-private partnerships to help with resource creation.

The primary goals were to outline the development, testing, and deployment of technologies for using hydrogen energy in the transportation and power-generating sectors and to make it possible to build the necessary infrastructure throughout the nation. It entailed concentrating on the growth of various links throughout the complete hydrogen energy value chain, from its production to its availability for ultimate use and resolving concerns linked to its safety and standards. Only a few sets of two-wheelers, three-wheelers, catalytic combustion cooking systems, small power generating systems, hydrogen internal combustion engines (HICE), and FC buses have been developing. These have only undergone limited field testing. Activities for developing hydrogen-fuelled vehicles (HFV), including hydrogen-compressed natural gas (H-CNG) and hydrogen-diesel dual fuel vehicles, got momentum in India after NHER came into existence.

Goal of decarbonizing power system

The energy industry is experiencing a worldwide change. Renewables’ costs have plummeted significantly over the last decade—solar power up to 80% and wind power by roughly 40%—making them economically competitive with traditional fuels like coal and natural gas in most global markets. As a result, renewables are rapidly expanding: in 2018, they accounted for the vast majority of new power-generation capacity. In most markets, they are now the most cost-effective way to expand marginal capacity. Furthermore, for decarbonizing the power system renewables are crucial to any country’s goal to reduce greenhouse gas (GHG) emissions.

However, neither the sun’s nor the wind’s direction can changed. As a result, unlike baseload power facilities powered by coal, gas, or nuclear energy, wind and solar output cannot be continuously matched to demand. That raises a problem. Municipalities, states, countries, and utility companies all need affordable, dependable power. Many people have also established objectives to decarbonizing their electricity systems. How do they manage both?

For considerable amounts of renewable energy to integrate, flexibility (the capacity to control the erratic nature of non-dispatchable electricity) such as wind and solar power is essential. The real-time synchronization of supply and demand may achieved in various ways. For instance, gas and coal power plants may shift output up or down to balance wind and solar energy output variations, and production may balance geographically via transmission lines. Demand-side management programs and well-designed incentives can persuade people to change their consumption patterns.

Decarbonizing the electricity system to between 50 and 60 per cent by 2040

In most markets, achieving 50 to 60 percent decarbonization with little to no additional expenditure is possible beyond what is dictated by just rational economic behaviour. Decarbonization is frequently the least expensive choice since solar, wind, and storage costs—three crucial components in all deep-decarbonization scenarios—have fallen so far and so quickly.

Midrange storage (four to eight hours) works well with the sun’s 24-hour cycle. “Solar-plus storage” refers to the ability to store energy during the day. And release it at night to ensure a consistent supply of electricity . In reality, wind and solar energy frequently work in tandem since the former is stronger at night and during the winter, when the latter is. Therefore, solar and wind resources markets are better equipped to handle intermittency.

The performance of the electricity system normally wouldn’t be significantly impact reaching this degree of decarbonization. We project that 2 to 5 percent of the electricity generated would curtailed, and almost all of it undergoes various utilizations. Individual fossil-fuel plants’ utilization levels, or the proportion of time a plant produces power, would likewise not considerably changed, remaining at 50 to 60 percent. However, some assets will decommissioned and replaced when more affordable renewables come online, and no new transmission would likely required. Simply put, few changes would need to be made to the electricity system to reach a 50–60% decarbonizing goal.

Decarbonizing the electricity system to between 80 to 90 per cent by 2040

It will often cost more, take longer, and need more market-specific initiatives to reach 80 to 90 percent decarbonization. Even if there is no need for new technologies, storage would have to utilized for longer periods, and demand may need to controlled more strictly. This may done by actively managing building heating, cooling, and industrial load shifting. Additional transmission interconnections may require for certain markets to combine renewable resources and share baseload resources over a greater geographic region.

The system would seem considerably different from how it does now at this level of decarbonization. Because so much renewable energy is producinig to fulfil demand during reduced output, we expect a 7 to 10% curtailment. Fossil-fuel plants are used less frequently (20–35%) as renewable energy sources gain popularity. However, many are maintaining on standby to supply demand when renewable energy sources cannot. The expenses of decarbonization at the 80 to 90 percent level vary greatly. There may be a slight decrease in system expenses (1 to 2 percent annually) in markets with higher than average power costs, and there may be gains in other, less expensive markets.

Decarbonizing the electricity system to between 100 per cent by 2040

Biofuels

 Landfill gas and biomethane are examples of net-zero-carbon renewable biofuels. However, due to their high cost and finite availability, they can often only partially contribute to the solution. 

CCUS

 stands for carbon capture, usage, and storage. With CCUS, greenhouse gas emissions from burning fossil fuels have applications in various processes like better oil recovery, or safely stored in deep rock formations. Although costly, CCUS is effective. Finding and implementing technology advancements and establishing scale efficiencies will be necessary to lower the cost. Additionally, as CCUS cannot collect every carbon molecule, other technologies will still require to achieve complete decarbonization.

BECCS

It stands for bioenergy carbon capture and storage. According to a method known as BECCS, carbon-neutral biomass, such as wood pellets and agricultural waste, undergo burning for fuel while the CO2 emissions that occur either captured or stored. The end outcome is negative emissions, or removing GHGs from the atmosphere. Biomass can be ramped up, but it is unclear how much because the technology is still relatively new. One benefit is the ability to convert old coal facilities into BECCS plants, which lowers capital costs and uses already-existing linkages. 

P2G2P

Power to gas to power. Using surplus electricity, P2G2P technology creates hydrogen that may stored in the gas network and then transformed back into power. The “clean gas” produced by P2G2P technology permits storage for weeks or even months. However, it is both costly and ineffective. The initial ten megawatts of generated power undergo tr6ansformation into usable power for consumption, roughly three megawatts remain. However, the flexibility offered by P2G2P technology might go a long way toward incorporating sporadic renewables if there is a demand for clean gas beyond the power industry.

DAC

DAC remove CO2 from air. It is another low-emission technology that might utilize to reduce the final few percentage points of electricity that is carbon-intensive. Although the technology has proven, it require enormous energy expenditures to capture, isolate, and sequester CO2. Additionally, doing so is highly costly. Our research typically indicates that it is not a component of the answer for complete decarbonization.

What is Net Zero?

Countries, cities and companies are increasingly committing to reaching net zero by 2050 – removing as much CO2 as they produce to limit global warming. By definition, net zero emissions means reducing greenhouse gas emissions to the lowest possible level, with any remaining emissions reabsorbed by the atmosphere by means of oceans and forests.

The energy sector is critical to addressing the global climate crisis as it is the primary source of worldwide emissions. Governments have made numerous commitments and efforts to tackle the causes of global warming. Yet, since the United Nations Framework Convention on Climate Change was signed in 1992, CO2 emissions from energy and industry have increased by 60%.
The number of international pledges and initiatives is rising. However, they are still far short of what is required to keep global temperature increases to 1.5 °C and prevent the worst effects of climate change. The goal to Net Zero by 2050 Roadmap, which identifies more than 400 milestones for what must be done and when to decarbonize the global economy within three decades, offers a roadmap to accomplish this challenging and vital goal. A normative IEA scenario called Net Zero Emissions by 2050 (NZE) shows how the global energy sector can achieve net zero CO2 emissions by 2050, with advanced economies achieving net zero emissions ahead of others. Short- and medium-term emission reduction goals, consistent with the Paris Agreement, are set all over the globe to eliminate the worst impacts of climate change this decade. 

The importance of corporate Net Zero targets 

To achieve this, we must balance what we harvest from the environment with the greenhouse gases we release into the atmosphere. 

So as to prevent the harmful effects of climate change, 197 nations pledged to maintain temperature increases well below 1.5°C under the Paris Agreement in 2015. 

In its report from 2018, the Intergovernmental Panel on Climate Change (IPCC) concluded that “global net human-caused carbon dioxide emissions would need to fall by about 45% from 2010 levels by 2030, reaching net zero around 2050. pooiiz

Accordingly, any remaining emissions brought on by human activity that cannot be reduced must be offset by removing CO2 from the atmosphere.

Khaitan on the way of Net Zero target. 

An increasing number of countries, cities and organizations have pledged to reach this goal within 2050. Thus turning the net zero promise into a mainstream act. Khaitan bioenergy aims on net zero and decarbonisation by being part of organizations that support target. The initiative “Net Zero Tracker” has mapped out the number of net zero pledges of countries, cities, regions, and organizations. The focus is to get an impression of how significant an impact these entities may have on reaching the target. According to the reports, 90% of the worldwide economy is committed to achieving net zero. Out of 2000 of the largest publicly traded companies worldwide, the Net Zero Tracker has identified 683 with target. 

 Net Zero targets by various corporates

On an organizational level, the quality of the net zero targets varies. While some companies have set ambitious targets for deep emission cuts, others have set modest emissions reduction targets. Mainly lacking detailed abatement planning. The variation in the quality and structure of targets makes it harder to compare companies’ net zero targets and their implications.  

The Net Zero Standard 

The net-zero commitments need to translate into quantifiable goals and plans for which businesses can held responsible. Net zero aims are now more transparent, comparable, and likely to be of high quality. And also it succeed by being in line with standards. One such standard that provides substance and direction to targets is the SBTi’s (Science Based Targets Initiative) Net Zero Standard. The SBTi Net Zero Standard offers a comprehensive, common net zero concept grounded in science. The standard is the first of its kind in the world to give businesses a way to contribute. Also to making the world economy reach the goal.

Corporate net zero targets vary in three ways: the target’s boundaries, the mitigating measures selected, and the deadline for achieving the target. Aiming for significant emission reductions in its scopes 1, 2, and 3 of at least 90% by 2050 . Also halving their emissions by 2030, businesses to comply with the Net Zero Standard must set both long and short-term goals.

According to the Net Zero guiding principles, there are two requirements for achieving net zero and keeping warming to 1.5°C: 

1. Achieve value-chain emission reductions on a scale. It is consistent with the level of mitigation reached in paths that keep global warming to 1.5°C with no or minimal level. 
2. To permanently remove an equivalent amount of atmospheric Carbon dioxide. Thus to offset the effects of any remaining sources of residual emissions. 

Corporate net zero targets are crucial for businesses to demonstrate that the private sector can advance the fight against climate change. Pledges for net zero are becoming more common, but setting a science-based goal demonstrates accountability.

Refinery Carbon Reduction

The following strategic actions should follow to reduce direct CO2 emissions at oil refineries:

Energy efficiency

Improvements in energy effeciency considered by many as a cost-effective mitigation method. Although they may only be able to reduce emissions by 5-10%.
The rebound effect, a phenomenon that would somewhat offset the advantages. It has also been suggesting as a possible outcome of increased energy efficiency made possible by technological advancements.
Increases in energy efficiency cannot primarily drive the decarbonization of the refining sector.

Carbon Capture and Storage

Since the 1970s, the oil and gas refineries has pioneered using CCS technology. It mainly focus for enhanced oil recovery (EOR), establishing a foundation for its implementation in other CO2 mitigation applications.
There has been extensive research on using CCS technology to lower emissions in refineries.
The general view is that collecting CO2 from larger combined emission stacks is feasible.

The forecasts include CO2 capture from bigger emission sources. It may be steam methane reformers, fluid catalytic converters, crude atmospheric and vacuum distillation units, and power plant stacks.
According to their assessment, the CO2 capture and compression system comes in second place. With a cost of 47%, followed by interconnectors. It retrofits at 38% and utility plants operating on natural gas at 15% of the total cost of CO2 avoidance.
On the other end, several emissions from boilers, heaters, or furnaces dispersed around a refining site are more complex to control because of their lower CO2 concentrations and flow rates, as well as the possibilities for contaminants.
The economics of CO2 capture from various diverse point sources is still poorly understandable. Thus site-specific assessments need for a more accurate estimation.

Fuel Shifting

Fuel shifting is another important to choose the appropriate approach considering fuel combustion contributes to about 70% of a refinery’s emissions.
Switching to biomass could produce a significant environmental burden and potentially disrupt the biomass industry, despite being appealing in terms of CO2 reduction and cost.
Also, because of administrative and security concerns, direct-fired heaters and boilers utilizing solid biomass are considering as impractical in oil refineries.

On the contrary line, gaseous fuels, specifically for the combined heat and power (CHP) plant, could function as drop-in fuels without the requirements for extensive refinery operations restructuring.
Although there is an anticipation that the operation of hydrogen-fired boilers will be as stable as that of their natural gas equivalents, such boilers have not undergo testing in a manufacturing environment. Thus raising the question about the type of heat transfer and the degree of gas emissions.
The same is for electric heating if operating costs dramatically lowered and the technology demonstrated to be dependable.

The worldwide energy sector in 2050 is based mainly on renewables, with solar the single largest source of supply.
All governments must have a single, constant objective while collaborating closely with corporations, investors, and citizens to bring about this cleaner, healthier future.

Electricity is a beneficial alternative to power several modes of transportation to make them more environmentally friendly. Since an electric car emits no harmful pollutants, it lowers greenhouse gas emissions (GHG). Also, this would aid in tackling the planet’s climate concerns. Also, these environmental crisis has prompted the government to take the lead in making significant changes over the past years. According to a report published in 2021, the transportation sector, which serves as an economic infrastructure for travel and freight, accounts for 25% of total energy consumption. Hence, e-mobility is one such initiative to reduce the consumption of fossil fuel derivatives.

The proposal is to enable automobiles’ electric propulsion by using electric powertrain technology, in-vehicle information, connectivity, and connected infrastructures. Plug-in hybrids and fully electric vehicles use powertrain technology to convert hydrogen fuel into electricity.

There are more types of electric vehicles than e-cars, e-scooters, e-bikes, e-motorcycles, e-buses, and e-trucks. They all have a battery and charging systems, are powered entirely or partly by electricity, and primarily obtain their energy from the grids through distribution networks that follow set standards. Thus, combining all these aspects completes the ecosystem for electric mobility. Corporate fuel economy, pollution standards, and market expectations for lower operating costs drive e-mobility initiatives.

Different types of e-mobility vehicles

Battery Electric Vehicle (BEV)

BEV is commonly known as a pure electric vehicle. This type of electric vehicle has an extensive rechargeable battery on-board that provides all the energy the car needs to propel forward. Examples include the Tesla Model 3, Chevy Bolt, and Nissan Leaf.

Hybrid Electric Vehicle (HEV):

HEVs are series hybrids or parallel hybrids with engines and electric motors. Where the engine powered by fuel, while batteries power the motor. Hybrid electric vehicles are powered by an internal combustion engine and one or more electric motors, which use energy stored in batteries. Hybrid electric vehicle batteries are charged through regenerative braking and the internal combustion engine. The extra power provided by the electric motor can allow for a smaller engine. The battery can also power auxiliary loads and reduce engine idling when stopped. Together, these features result in better fuel economy without sacrificing performance.

Plug-in Hybrid Electric Vehicle (PHEV):

PHEVs, also a series hybrid, have an engine and a motor. You can pick between conventional fuel (such as gasoline) and alternative fuel (such as bio-diesel). A rechargeable battery pack can also power it. External charging is possible for the battery.

Contributors in e-mobility sector

Mobility sector combines a group of stakeholders who is essential for the success of electro mobility system. The efficient and effective functionality of these stakeholders ensures the smooth functioning of the system.

Manufacturers of EVs and accessories:

An electric vehicle is built and operated in large part by automakers (also known as auto OEMs) and other businesses including battery manufacturers, EV accessory manufacturers, maintenance service providers, etc.

Charge station manufacturers:

The companies that fall under this category are ChargePoint Inc., ABB, Tesla, Engie, AeroVironment, Schneider Electric, Siemens, Efacec, Bosch, etc. They develop the hardware and software for the charging stations in accordance with different standards and guidelines. However, in addition to selling their gear and software to charge point operators, several manufacturers also function as CPOs and EMPs/MSPs.

Charge Point Operator (CPO):

The administration and technical facets of the charging station are under the control of the charge point operator (CPO). Today, there are numerous charge point operators in every country who offer a variety of functions and station designs. These are just a few of the duties that a typical charge point operator might have: Installation, operation, maintenance, and servicing of charge stations are all technically based. Billing input to EMP, accessibility, authorization for roaming, etc. are administrative aspects.

E-Mobility Service Providers:

E-mobility service providers make it feasible for electric vehicle users to use the infrastructure for charging (EMSP or EMP). Many EMP may engage in arrangements with charge point operators (CPO) and provide end consumers with e-mobility even when they do not own the charging stations.
With the end-user (EV driver), E-Mobility providers (EMP) enter into a contract, offer to charge tags or RFID cards, and take care of the services’ billing.

Grid Operator (DSO):

The DSOs are the local grid operators (Distribution System operators). They are the ones who “supply” power to homes, workplaces, or public streets; they develop, operate, and maintain public distribution grids.

Transmission System Operator (TSO):

TSOs and DSOs work closely together to maintain the grid balanced. The TSO is responsible for maintaining a stable grid load in each neighborhood. They work with DSO to maintain “demand” and balance power distribution. They also configure profiles to reduce supply in each location as needed.

Power generation / Utility Supplier:

Utility infrastructure powers the charging stations. These businesses produce energy often; some may even own different power plants (such as wind, solar, nuclear, hydro, etc.), yet, some may buy power from other producers.

Regulating authorities

The ecosystem’s most important stakeholders are government representatives, decision-makers, and regulatory agencies. In addition to industry measures like “subsidies” to promote the market, they also set laws controlling the obligations of each of the stakeholders above.

India’s perspective on e-mobility

Most people in India belong to either middle-class families or are part of the poverty line. But in the past few years, most people have owned a car. All the cities in India are overpopulated with vehicles. Due to this reason, air pollution is increasing irrepressible. For example, Delhi, the country’s capital city, has shown the air quality index to be toxic and increasingly deteriorates daily. As scientists claim, if this kind of effect is not managed appropriately and continues for an extended period, humans would be bound to carry their oxygen tanks for survival. It is believed that introducing electric vehicles can resolve this problem to a certain extent.

Furthermore, there is a common misperception that EV two-wheelers are more expensive than their classic ICE equivalents. While the upfront cost of an EV may be higher than that of an ICE, the evaluation is complete once we consider the total cost of ownership (TCO). It includes the purchase price, operating costs (fuel/charging fees and maintenance), and resale value modifications. Climate change, rising fuel prices, and urban transportation challenges are all threatening to alter the future of mobility. E-mobility, to a considerable extent, addresses all of these difficulties. While the first electric vehicle was launched in India in 2001, the fundamental shift from internal combustion engine (ICE) based vehicles to electric vehicles (EV) started only in the last five years. According to NITI Aayog and Rocky Mountain Institute, India’s EV market could touch US$152.2 billion by 2030.

How successful is the e-mobility project

Pollution from transportation is especially significant in cities, where many people and vehicles move within a small geographical space. As a result, air pollution has become a more prominent policy priority. E-mobility reduces NOX and soot emissions in cities. With better and more environmentally friendly public transportation, more walking and bicycling infrastructure, and improved electric car infrastructure, cities also have opportunities to rethink traffic.

For prospective consumers, electric automobiles are pretty intriguing. We may anticipate additional improvements in the field as established automakers concentrate on e-mobility. These businesses may advance EV adoption by utilising their dealership networks, business information, and R&D skills. The champions of e-mobility will be two-wheelers, while four-wheelers may still need some improvement before the TCO of EVs becomes more profitable. In conclusion, India’s future for e-mobility is quite bright despite infrastructure and demand issues.

For decades, sustainable mobility has been a pressing issue. There are now numerous alternatives to the traditional modes of transportation. There are electric vehicles, carpooling, hydrogen-powered buses, and countless other options. All these new alternative methods significantly impact the reduction in the release of harmful pollutants. However, biofuel-powered vehicles, also known as flex-fuel vehicles, provide more drastic results by replacing the use of fossil fuels. In India, Maruti Suzuki, Toyota, and Hyundai have agreed to launch cars with multiple fuel compatibility, which would be possible in the coming years.

Flex Fuel Vehicles (FFV) have engine flexibility with different fuel compatibility. These vehicles support many single blends or fuel combinations and can support more than one fuel type. But the standard compatibility is flex fuels. It consists of gasoline-ethanol blends up to 85% ethanol or fuel based on methanol. E85 is a combination of a gasoline-ethanol mix based on the ethanol percentage.

Flexible Fuel Vehicles consist of an internal combustion engine (ICE) that generates power with the help of heating the trapped air and thus burning any fuel present. As said, It runs majorly on the E85 blend; the blend percentage of ethanol can be 15% to 85%. The rate of combination used can depend upon geography, availability or the seasons. The consumer needs to know their vehicle’s capacity and fuel compatibility. 

FFVs are similar to conventional gasoline-only vehicles, except for an ethanol-compatible fuel system and a different powertrain calibration. While higher ethanol levels generally reduce fuel economy and many FFVs have improved acceleration performance when operating on higher ethanol blends.

Benefits

Environment Friendly

Flex Fuel Vehicles support sustainably produced fuel blends. As already mentioned, ethanol (E85) is a renewable fuel which doesn’t adversely affect the planet compared to fossil fuels when burned. It releases significantly less smoke and doesn’t release toxic greenhouse gases (GHG) into the atmosphere. 

Fuel Flexibility

Any combination of fuel is compatible with a flex fuel vehicle as it has sensors that understand the fuel type and adjust its combustion process accordingly. It allows the consumer flexibility to fill their fuel tanks based on availability. 

Self Reliance

The sustainability and availability of resources for extracting flex fuels ease the country’s struggle for oil imports. Hence, This encourages every nation to be self-reliant on the available resources for flex-fuel. 

Engine Efficiency

The engine performance of FFV is still arguable. But current studies have shown the results of better engine performance and the ability to burn pure and cleaner fuels such as ethanol and methanol blends. Zinc, brass, copper, lead, and aluminum are incompatible with storing pure blends as there is a risk of corrosion.

Benefits on Taxes

There would-be many tax benefits for FFVs consumers also could claim tax credits after purchase. Also, In the long run, there is an elimination of tax obligations as well.

Challenges

Single-Crop Use

Flex-fuel can be produced sustainably using corn and sugar, which is mass produced but has a drawback. The inability to use crops made for flex-fuel production for other purposes could increase the cost of animal feed. In addition to being susceptible to plant pathogens, corn can be negatively impacted by weather events like floods and droughts.

Potential Engine Damage

Everyone wants to give their vehicle the best care possible. Unfortunately, ethanol is mild cleaning solvent which readily absorbs dirt, potentially eroding and harming the engine in the long run. Thus, it is to be maintained on time to time basis.

Fuel Economy

Gas mileage is one of the main issues with flex-fuel vehicles. While some experts claim that flex-fuel vehicles get similar gas mileage to conventional cars, others assert that they get worse gas mileage. While ethanol does increase a car’s octane rating, it has less energy than gasoline. So, yes, using ethanol will result in lower miles per gallon. But because ethanol is less expensive than regular gas, the savings should compensate for the reduced mileage.

Limited Number of Gas Stations

Gas stations are less likely to stock flex fuel because it isn’t as cost-effective as regular gasoline. Ethanol is currently only available at a small fraction of gas stations nationwide, but the situation will be different in the coming years. 

Facts and Figures

Comparisons of tailpipe emissions for E85 versus gasoline of flex-fuel vehicles (FFVs) 

The tailpipe emissions of E85 from flex-fuel vehicles (FFVs) and regular gasoline have been compared in various ways, with varying results. Based on actual measurements of five FFVs made with a portable emissions measurement system (PEMS), additional chassis dynamometer data, and projections from the Motor Vehicle Emission Simulator (MOVES) model, differences in FFV fuel use and tailpipe emission rates are quantified for E85 versus gasoline. Despite average rates being lower on E85 than gasoline, an individual FFV may have higher nitrogen oxide (NOx) or carbon monoxide (CO) emission rates due to inter-vehicle variability. Comparing the tailpipe emission rates of E85 and gasoline is sensitive to vehicle-specific power, according to PEMS data (VSP). For example, while CO emission rates are lower in all VSP modes, they are proportionally lower at higher VSP. Driving cycles with a high power demand are better for CO emissions but worse for NOx.

The vehicle’s fuel cycle and tailpipe emissions were considered in a life cycle inventory. Although E85 for FFVs emits less nitrogen oxide (NOx) from the tailpipe than gasoline, this is advantageous for the communities where the vehicles are used. The life cycle NOx emissions are higher due to higher NOx emissions during fuel production. According to dynamometer data, the average difference in tailpipe emissions between E85 and gasoline is 23% for NOx and 30% for CO, and there isn’t a noticeable difference for hydro-carbons (HC). Emissions from fuel production typically occur in rural areas, and there are no significant variations in overall hydro-carbon emissions. 

The wide range of vehicle-to-vehicle fluctuation explains why earlier studies with smaller sample sizes yield inconsistent results. E85 significantly reduces nitrogen oxide (NOx) and carbon monoxide (CO) emissions from tailpipes compared to gasoline, which may be advantageous for controlling ozone air quality in NOx-restricted areas. Comparisons of the FFV tailpipe emissions of gasoline and E85 are sensitive to driving style and power demand.

Future of Flex Fuel Vehicle

There are arguments for and against flex-fuel vehicles. However, using ethanol as a cost-effective and environmentally friendly fuel source makes way to switch toward a flex-fuel car in the future. There are many benefits to using flex fuels and flex-fuel-supported transportation vehicles. Since technology is ever-evolving, it is impossible to predict what flex-fuel cars and more cutting-edge innovations might appear over the coming years.

It might not be easy to figure out Flex Fuel vehicles. However, a few telltale signs in flex-fuel vehicles differentiate them from regular cars. Examples involve yellow gas caps or a yellow ring where the manufacturer’s fuel nozzle goes on flex-fuel vehicles. Other cars can use flex-fuel due to the labels on their fuel doors. In a nutshell, using alternative renewable fuels and sustainably powered vehicles is the future that can save time and money and also contribute to reversing the adverse effects of global warming.
