Pioneering Sustainable Aviation: The Rise of Sustainable Aviation Fuel (SAF)

Introduction

The aviation industry, long criticized for its significant carbon footprint, is undergoing a remarkable transformation with the advent of Sustainable Aviation Fuel (SAF). As countries worldwide commit to reducing greenhouse gas (GHG) emissions, Europe’s instruction requiring flights to have 2% SAF by 2025 is a bold initiative. Similarly, India’s pledge to blend 1% SAF into aviation fuel by the same year signals a significant step towards sustainability. In this blog, we explore the journey of SAF, the implications of these mandates, and how Khaitan Bio Energy is poised to play a pivotal role in India’s SAF production.

The Rise of Sustainable Aviation Fuel (SAF)

SAF, or bio-jet fuel, is derived from renewable feedstocks such as agricultural residues, waste oils, and algae. Unlike conventional jet fuel, SAF significantly reduces greenhouse gas emissions and other pollutants. Thus making it a vital component in the aviation industry’s quest for sustainability. It is estimated that SAF could contribute around 65% of the reduction in emissions. Thus needed by aviation to reach NET ZERO CO2 emissions by 2050.

It is sustainable because the raw feedstock does not compete with food crops or water supplies. Otherwise is responsible for forest degradation. Whereas fossil fuels add to the overall level of CO2 by emitting carbon that had been previously locked away. Also SAF recycles the CO2 which has been absorbed by the biomass used in the feedstock during the course of its life. By design, these SAFs are drop-in solutions, which can be directly blended into existing fuel infrastructure at airports. And are fully compatible with modern aircraft. In 2022, global SAF production was estimated to be around 375 million litres. Thus covering only around 0.1% to 0.15% of total jet fuel demand.

Europe’s Mandate: Leading the Charge for Sustainability

In a landmark move, the European Union (EU) has mandated that all flights arriving in European airports must incorporate at least 2% SAF into their fuel mix by 2025. This ambitious target underscores Europe’s commitment to reducing carbon emissions in the aviation sector. It sets a precedent for global sustainability efforts. The mandate incentivizes airlines to invest in SAF and spurs innovation and biofuel industry investments.

The legislation provides for incorporating SAF for 2% of their overall fuel mix from next year, rising to 6% in 2030 and then soaring to 70% in 2050. These requirements will apply to all flights originating in the EU, regardless of destination. Airlines will receive approximately two billion euros in funding from the EU carbon market to assist with the transition.

SAF production in Europe is still in its early stages. As highlighted by Airlines for Europe (A4E), an association representing major airline groups on the continent, such as Ryanair, Lufthansa, IAG, Air France-KLM, and easyJet. As compared with traditional jet fuel, SAF is significantly more expensive. However the costs are expected to come down as more technological advancements take place in this space. By steadily increasing the percentage of SAF mandated for fueling, they hope to drive the SAF production costs down. This is a necessity as the EU does not currently have the production capacity to meet the SAF required under the 2025 2% mandate.

The U.S. Sustainable Skies Act

The aviation industry in the U.S. accounts for over 11% of transportation related GHG emissions. To achieve NET ZERO emissions, the U.S. Government is working closely with the private sector to increase the production of SAF. The U.S. Congress introduced the Sustainable Skies Act in May 2021, aiming to boost incentives to use SAF by providing tax credits to manufacturers. The credit will start at 1.50 USD per gallon for blenders that supply SAF with a demonstrated 50% or greater lifecycle GHG savings. These tax credits will help cut costs and rapidly scale domestic production of sustainable fuels for aviation.

In early September 2021, the U.S. announced a new sustainable aviation fuel goal to increase the production of SAF to at least 13 billion litres per year by 2030 and to 160 billion litres per year by 2050, thereby putting the aviation sector on the pathway to achieve NET ZERO carbon emissions by 2050.

India’s Ambitious Goals: A Paradigm Shift in Aviation

Following Europe’s lead, India has set its sights on sustainable aviation, aiming to blend 1% SAF into aviation fuel by 2025. This mandate, announced by the Ministry of Civil Aviation, represents a paradigm shift in India’s aviation sector. Also this aligns with the country’s broader climate goals. By promoting the use of SAF, India seeks to reduce its carbon footprint. Thus enhance energy security, and foster innovation in the biofuel industry.

India, guided by Prime Minister Modi, is determined to attain net zero emissions by 2070. This demonstrates that this vision is supported by tangible commitments as well.

Union Minister of Petroleum & Natural Gas and Housing & Urban Affairs, Hardeep Singh Puri, has once again emphasized it. The importance of India implementing mandatory blending of sustainable aviation fuel (SAF) with jet fuel. During an exclusive interview with Moneycontrol at the India Energy Week 2024, the minister stated that discussions are currently taking place to introduce this mandatory blending. Furthermore, he highlighted that India and Brazil are the only two countries in the world that can become major SAF manufacturers.

Puri stated, “If Europe were to introduce a mandatory SAF blending of 5 percent with Jet Fuel, India and Brazil would be the only two countries capable of manufacturing the required SAF.” He further suggested that the Indian government could significantly increase its SAF production. This is by incentivizing the collection of used cooking oil from hotels, restaurants, and street vendors.

India currently needs policies governing Sustainable Aviation Fuel (SAF), unlike Europe or the US. However, in an effort to reduce emissions and contribute to a more sustainable planet, India has set a target of using 1% SAF for domestic flights by 2025. This is as stated by our Minister of Petroleum and Natural Gas. The adoption of SAF in India would signify a significant milestone in our commitment to environmentally responsible aviation operations.

Transportation Fuels and Greenhouse Gases – Unveiling the Connection

Introduction

The modern world thrives on the wheels of transportation, a dynamic network that connects people, places, and goods across the globe. However, this convenience comes at a steep environmental cost – the emission of greenhouse gases (GHGs) from transportation fuels. This comprehensive exploration delves into the intricate relationship between transportation fuels and greenhouse gases, unraveling the science, understanding the impacts, tackling the challenges, and envisioning a future where sustainable mobility takes the lead.

The Greenhouse Gas Equation

Before diving into transportation fuels and greenhouse gases, let’s lay the groundwork by understanding the science behind this complex equation. Greenhouse gases, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), create a natural blanket around the Earth, allowing sunlight in while trapping heat. This greenhouse effect is essential for maintaining the planet’s habitable conditions. However, human activities, primarily the burning of fossil fuels, have released excess gases into the atmosphere, amplifying the greenhouse effect and leading to global warming.

The Fossil Fuel Connection

The transportation sector stands as a significant contributor to these emissions. At its core are fossil fuels – the lifeblood of vehicular movement. Gasoline and diesel, derived from ancient organic matter, are the predominant fuels that power cars, trucks, ships, airplanes, and trains. When these fuels combust, they release energy and a barrage of pollutants, including carbon dioxide. This carbon dioxide forms an intricate link between transportation fuels and the greenhouse gases that drive climate change.

The Ominous Impacts of Transportation Fuel Emissions

The convenience and interconnectedness brought about by modern transportation have undeniably transformed our world. Yet, as we speed down highways and soar through the skies, there’s a hidden cost that we can no longer afford to ignore: the profound impacts of transportation fuel emissions. In this blog, we’ll delve deep into the intricate web of consequences that arise from these emissions, touching on climate change, air quality, ecosystem disruption, and more. Moreover it’s time to lift the veil on the far-reaching effects of transportation fuel emissions and consider the urgent need for change.

Global Warming: Heating Up the Planet

At the forefront of the impacts of transportation fuel emissions is the specter of global warming.

Lignin Valorization

In the last decade, lignocelluloses have drawn the scientific community’s attention as a rich resource for 2G ethanol production and other by-products. This is highly important because of many reasons. It mainly include climate change concerns. Also the risks of interruptions in food supply chains in various parts of the world are becoming more urgent. In this circular economy, lignin valorization in biorefineries serve as the highly suitable industrial platform to develop the essential chemical changes.

Biorefineries are defined by the IEA as the sustainable processing of residual biomass into a wide range of bio-based products. It mainly includes food, feed, materials, chemicals etc and bioenergy like fuels, power, heat etc. Furthermore, the main goal of the biorefineries are the complete valorization of stubble. Thereby lowering the environmental pollution through an alternative energy or materials and to achieve less dependency on fossil-based fuels and materials.
Regarding the lignocellulosic biorefineries, there are still important limitations that still make them non-cost-competitive.

The first commercial lignocellulosic ethanol production facility started in the U.S (2013). Initially plan consists of the construction of 5 lignocellulosic ethanol plants from 2013 to 2016. However only one ethanol plant was in operation in 2019. Moreover, the maximum lignocellulosic ethanol production from this biomass source peaked in 2018 at 15 million gallons. Far behind the expected target of 7 billion gallons expected. As a result of the ability to produce low to high-value compounds on a large and stable basis from lignin. Lignocellulosic biorefineries could potentially become more economically viable. Also competitive by offering a diverse range of products instead of just methanol.

Definition of Lignin and its features

Lignin is the complex chemical compound most derived from biomass. It is a set of non-sugar molecules acting like glue to hold the fibres. It is a chemical bond of carbohydrate materials, occurs throughout the cell wall, and fills the spaces in it. Lignin is the main component of lignocellulosic biomass, making up about 15-30% of its weight. The three main monomers consists of almost all lignin found in nature are:

p-Coumaryl alcohol-minor component of stubble

Coniferyl alcohol-mainly found in softwoods

Sinapyl alcohol-building blocks of hardwood lignins

Considering the chemical structure of lignin, it is composed of three primary phenylpropane units or hydroxyl cinnamyl alcohols. It mainly consists of guaiacyl propanol (G), syringyl propanol (S) and p-hydroxyphenyl propanol (H). These all link through various chemical bonds. Although the phenylpropane units have similar chemical structures, their differences rely mainly on the quantity of substitution of methoxy functional compounds.

Importance:

Adhesive of wood
Binds the fibres
Provides rigidity and toxicity to the wood
It is the most slowly decomposing component of biomass, contributing a significant part of the material that becomes humus as it decomposes.

Uses and Properties:

The lignin adds compressive strength and hardness to the cell wall of plants and have a major role in the evolution of greens by suporting them to withstand the gravitational force. It also waterproofs the plant’s cell wall, supporting the upward movement of water in xylem tissues. Lastly, lignin has antifungal properties and often rapidly deposits in response to fungal infection, protecting the plants from the diffusion of toxic fungal enzymes.

Lignin is removed from wood pulp in manufacturing paper. It is mainly by treatment with chemical agents such as sulfur dioxide, sodium sulfide, or Sodium hydroxide.

Particleboard and similar laminated or composite wood products contain lignin as a binding agent, as a soil conditioner, as a filler or as an active ingredient of phenolic resins, and as a linoleum adhesive. Vanillin (synthetic vanilla) and dimethyl sulfoxide are also made from lignin.

The main properties of lignin include:

Highly stable material. So it requires treatment with solid alkali at high temperatures.
Stable with acids
Oxidizing agent
lignin structure is complex.

Sustainability of lignin valorization

Lignin is the second rich biopolymer in stubble, with high potential as a source of many aromatic chemicals and compounds required for construction. Over-exploitation of lignin can raise the profitability of many lignocellulosic biorefineries and the production of biobased products that can contribute to reducing greenhouse gas emissions from those of equivalent fossil fuel-based processes. However, one of the main obstacles to the full exploitation of biobased materials is the complex structural variation of isolated lignins due to the natural variability of biomass feedstocks and the differences in biorefinery layouts: The distribution of molecular weights, the distribution of available groups, and the residual impurities are all affected.

Large volume and low specific value applications of lignin include producing energy and biofuels. In contrast, small-volume and higher value-added applications include the production of chemicals through lignin depolymerization and specific functionalization.

Future of Lignin Valorization

While the most common lignin from the pulp paper industry currently accounts for 170 tons/year, additional important current lignin include lignosulfonates, alkali lignin, acid hydrolysis lignin, steam explosion lignin and organosolve lignin. The development of novel pretreatment technologies at the industrial scale, such as steam-assisted pretreatment or solvent-assisted biomass fractionation, has led to novel lignins from novel feedstocks with characteristics suitable for more targeted potential applications.

The current review consists of the analysis of the available technical lignin with a special focus on lignins stemming from new technologies and producers, including market volumes at the global level. At the European level, many projects have been funded in the last ten years for the conversion of lignins to final products.

There are many challenges facing biorefineries, including novel and sustainable approaches to lignocellulose fractionation, treatment, transformation, and commercialization of the final products, as well as resolving a number of constraints that affect lignin treatment/transformation. This blog highlights the main restraints for industrial lignin valorization in light of its abundance as stubble and the sustability of lignin valolrization and its potential applications in different industries. In addition, lignin depolymerization propose a flexible and potentially resilient platform under instabilities in the market. Furthermore, Khaitan is implementing the essential technological tools to accelerate scientific breakthroughs in lignin research and the development of lignin for use as a source of fuels and materials in the future

Lignocellulosic biomass

How lignocellulosic biomass support sustainability

One of the most abundant resources in this world is biomass. Biomass consists of three primary materials such as cellulose, hemicelluloses and lignin. Therefore, biomass can consider as a lignocellulosic material. Lignocellulosic biomass (LCB) has dormant supremacy in defeating the present/future energy dilemma. This is due to the steady exhaustion of non-renewable fossil fuels. Lignocellulose also helps generate a wide range of bio-based chemicals and biofuels as sustainable feedstock. In addition to being polymers of sugars, cellulose and hemicellulose are using for sugar fermentation or converting sugars into products. Lignin is a polymer compound which contains phenolic compounds. Rice husk/stubble is one of the biomass with a high order of lignin. It has unique characteristics because of its silica content.

Khaitan bio energy uses high efficient techniques for lignin and silica extraction. It is done during the lignin isolation process following enzymatic saccharification. The technology has been so as to establish an end to end process for a self sustained integrated biorefinery. Most importantly it focusses a “Zero discharge facility”.

Khaitan bioenergy estimates to produce that tons of bioethanol yearly from lignocellulosic biomass obtained from stubble residues alone.

Simple diagrammatic view of Biomass – Fuel Conversion

Lignin and silica as by product

Among various biomass sources, the stubble primarily consists of cellulose (35–45%), hemicellulose (20–25%). Whereas the presence of lignin is 15–20% along with a high amount of silica and ash (10–15 %). Looking forward the production purposes of the paddy field are increasing. This results in 1.1–1.3 times straw as agro-residue in the last years. Eventhough available at a large scale and a low-cost source, stubble is still underutilised due to the high presence of silica, making it chemically and biochemically resistant (indigestible b). This leads to piling up in landfills and burning the field, causing substantial air and soil pollution.

In order o highlight the value of rice straw, converting it into high-value chemicals and fuels is an encouraging approach. However, the pretreatment of stubble is the bottleneck of the process to derange the unmanageable nature for bringing out sugar ompounds or other target chemicals. The method of acid hydrolysis is implemented in the pre treatment. Through this process, lignin and silica are simultaneously undergoes extraction to enhance holocellulose content and accessibility in the final product and produce selectively target chemicals.

The intricate nature of the composition of stubble is due to the rigid cell wall and the proximity of lignin and hemicellulose. Thus, holocellulose expects to disintegrate by chemical or biological pretreatments.This fantastic product of evolutionary developments has long shown potential as a highly sustainable and renewable source of fuels and materials.

The main use of Lignin for the manufacturing of biofuel or other useful compounds by two ways. Firstly by uncoupling lignin polymer from other cell wall polymers and secondly by exploiting the properties of lignin polymer for biofuel or for the production of other commercially useful products. Whereas Silica is widely used as a proppant. It holds open the fractures created by hydraulic fracturing allowing oil and gas to flow out of the formation.

Lignocellulose – A vital source to produce high-value marketable, and sustainable products.

Recently there has been a rise in research interest in the value or revaluation of lignocellulose-based materials due to increasing scientific knowledge, global economic and environmental awareness, legislative demands, and the manufacture, use, and removal of petrochemical-based by-products. The application of green technologies to extract and transform biomass-based carbohydrates, lignin, oils and other materials into a broader spectrum of marketable and value-added products with a zero-waste approach is a remarkable review.

Recognizing sources of biofuels such as biodiesel and biochar can reduce the environmental impacts of fossil fuels. Biofuels can also counter the raising demand of fossil resources and reduce reliance on non-renewable sources. However, it is essential to implement practical, scientific and robust tools to evaluate the exact advantages of using biofuels over conventional energy sources. Life cycle assessment has been identified as a comprehensive evaluation approach. This is to measure environmental impacts over the entire manufacturing chain of biofuels.

Bio-based economies have been the subject of significant research efforts. The main focus is to transform petroleum-based economies into socially acceptable, environmentally friendly, and comprehensively sustainable ones.

There is currently an intensive research effort in bio-refineries to develop sustainable and eco-efficient products to compete in the petroleum-based product market. Currently the energy reserves is becoming more and more difficult to access. Inorder to diversify the energy mix, Khaitan Bio energy operate in today’s most demanding environment enabling the transition to a more sustainable energy

H2, EV and Biofuel

The automobile industry is a core sector with inspiring success stories. The automobile industry’s estimated annual production is 22.93 million in FY 2022. It contributes 49% of India’s manufacturing GDP and 7.5 per cent to the country’s GDP. Further, Automotive manufacturers are seeking alternative methods to power cars and other vehicles to reduce carbon emissions and fossil fuel use. Such initiatives have driven the industry to launch vehicles adapted to biofuel, electricity, and Hydrogen.

What to know about 3 types of Fuel Alternatives

Resources like water, natural gas, fossil fuels, or biomass are the traditional raw materials for fueling a vehicle, which is now in limited supply. However, hydrogen is the most abundant element in the universe. Hence, Hydrogen cars (FCEVs) are those cars that have characteristics of both electric vehicles and conventional petrol cars. These cars produce electricity by allowing hydrogen to react with oxygen to create the chemical production of electricity and water vapour. Hydrogen cars are much faster to refuel than electric cars, reducing atmospheric pollutants’ emissions.

Electric vehicles (BEVs) are either partially or fully powered by electric power. EVs run on a lithium-ion battery, charged by plugging into a socket or any other charging unit. They are eco-friendly vehicles that can accelerate faster than vehicles with traditional fuel engines. Moreover, they are cheaper, noiseless engines that produce no exhaust fumes and are more reliable than hydrogen-powered vehicles. Globally, the Government have been investing in infrastructure for electric cars. There is widespread availability of charging stations in petrol pumps, motorway rest stops, shopping centres and even on specific streets for convivence and ease of access.

Biofuel is a renewable energy source from organic matter like wood, straw, sludge, sewage, vegetable oil, etc. It helps maintain a healthier and cleaner environment since there is no emission of hazardous gases, such as Carbon monoxide (CO) or Sulphur oxide (SO), thereby reducing the risk of global warming. Biofuel can be classified into first, second, and third generations based on their feedstock and production technology.

Differences between H2 and EV

Range

Hydrogen vehicles offer a higher range and faster refuelling when compared to electric vehicles. For, e.g. the Hyundai Nexo can manage 414 miles and only takes five minutes to fill up. The range of EVs is highly dependent on their vehicle. For instance, expensive cars like Tesla Model S have a range of 375 miles compared to a real-world range of 150 miles for the less expensive Nissan Leaf Acenta.

Availability of Charging/Refuelling Station

Hydrogen cars have less infrastructure, with only around 400 refuelling stations across the globe. Currently, In comparison, EVs have thousands of charging stations worldwide.

Cost of Ownership

Currently hydrogen cars are costly, with no affordable options in the market. But overall expense of FCEV’s can be lesser in comparison to BEV’s. On the other hand, the cost of an EV depends on the model and manufacturer.

Safety

Hydrogen is a safer alternative than conventional fuels in a multitude of aspects. Also, hydrogen is non-toxic, unlike traditional fuels. But safety concerns are still based on its flammable nature when stored in bulk. Electric vehicles have insulated high-voltage lines and safety features that deactivate the electrical system when they detect a collision or short circuit. All-electric cars tend to have a lower centre of gravity than conventional vehicles, making them more stable and less likely to roll over.

Emissions

Many conventional fuels are toxic or contain poisonous substances. These include potent carcinogens responsible for the increased risk of human cancer cell growth. But there are no greenhouse gas emissions from hydrogen. In the case of EVs, it has zero tailpipe emission as it runs on electricity.

Difference Between EV and Biofuel

Maintenance

An electric vehicle with no friction between moving parts or exchanges between liquids and gases needs neither lubricant nor exhaust. Stationary fuel cells, in particular, need very little maintenance, with servicing required once every one to three years.

Emissions

Though electric vehicles are not 100% green, they produce a fraction of the greenhouse gases and waste that a combustion engine car does. They even compared it to biofuel vehicles. The only greenhouse gases produced are in the actual manufacturing of the car and the emissions produced from the power plants supplying electricity to your home where your car vehicle is plugged in.

Limitations

The downsides are that there is a strict limit to how many miles can be traveled in a day on a full charge before needing to recharge. With biofuels, there is no limit since you can refuel in seconds compared to hours with an electric vehicle.

Availability & Accessibility

Biofuels are a renewable energy source. Because biofuels are derived from plant matter (and occasionally animal matter) that can be harvested annually or, in the case of algae, monthly, biofuels are theoretically unlimited. But in India, biofuel blending can only thrive as a fuel when it has a necessary infrastructure facility for extraction, production and distribution. However, the Union minister of India has addressed the necessity of flex-fuel vehicles and imposed a mandatory option towards automakers to offer cars that run on 100% biofuels within a few months. Electric vehicles are more accessible due to government policies to boost e-mobility and thus promote the development of a charging infrastructure network. There are currently over 10,76,420 electric vehicles and 1,742 Public Charging Stations (PCS) operational in the country.

Cost

Biofuel adaptive vehicles, also known as flex-fuel vehicles, are currently a concept but can be a real deal after a few months. Thus, the fuel price of bioethanol, a type of biofuel, would be Rs. 65 against the current petrol price of Rs.110. In contrast, electric cars in India, priced accordingly, include Tata Tiago EV (₹ 8.49 Lakh), Tata Nexon EV (₹ 14.99 Lakh) and Mercedes-Benz EQS (₹ 1.55+ Crore). Electric two-wheelers are priced from 50,000 to 2 Lakh.

Difference Between H2 and Biofuel

Emission

Hydrogen, after processing, generates electrical power in a fuel cell, emitting only water vapour and warm air. It holds promise for growth in both the stationary and transportation energy sectors. Emissions from biofuel, such as Carbon dioxide, carbon monoxide, sulfur dioxide, particulate matter and other hydrocarbons, are much less than conventional fuel.

Pricing

Hydrogen is cheap, and its combustion produces only water (no CO2). It has three times as much energy as an equivalent quantity of petrol. Current green hydrogen production costs range anywhere between ₹320 and ₹330 per kilogram in India. It can reduce to as low as ₹160-170 per kg by 2030, bringing parity with grey hydrogen and other fossil fuels. But hydrogen contains less energy per unit volume than all other fuels. Transporting, storing, and delivering it to the end-use point is more expensive per gasoline gallon. The average price of ethanol and biodiesel in India is Rs.70 per litre. However, there is a substantial difference in these prices among countries as well as states.

Potential

The transport sector, railways, and aviation is the major end-user of biodiesel, and bioethanol. It can also be found in automobiles, energy production, the chemical industry, etc. However, bioethanol production from fourth-generation feedstock is still in the embryonic stage. With India’s prime energy demand is to be doubled by 2040 and thus the demand of biofuel would increase as a result.

Based on FY 2021- quarterly update, India’s biodiesel market demand stood at 0.17 million tonnes despite major setbacks due to the pandemic induced disruption in supply chains. The report predicted a healthy growth of 8.60 per cent CAGR until 2030, with a forecasted demand set to reach 0.26 million tonnes. Also, for hydrogen induced fuel showcases similar growth potential as the cumulative value of the green hydrogen market in India could be $8 billion by 2030 and $340 billion by 2050. Electrolyser market size could be approximately $5 billion by 2030 and $31 billion by 2050.

Storage

Hydrogen is difficult to store due to its low volumetric energy density. It is the lightest of all elements, more delicate than helium, and quickly lost into the atmosphere. The onboard hydrogen storage systems expense is too high, particularly in comparison with conventional storage systems for petroleum fuels.

But in contrast, the storage of pure biodiesel from vegetable oil is to be safely kept at 45° to 50°F. In cold climates, Above-ground tanks may need to be heated or insulated, depending on the location. Also, biodiesel should not be stored or transported in copper, brass, bronze, lead, tin, or zinc because these metals will hasten degradation. If biodiesel is held for about four to five months, a stability additive to be used, especially in more southern climates due to increased temperature and humidity. Ethanol also tends to absorb water from the surrounding environment—stored in dry areas with low humidity. Ethanol will absorb any condensation that forms inside storage vessels.

Availability

The biomass feedstock required for biofuel are more expensive than petroleum. Also the processes for producing the fuel aren’t yet efficient enough to produce it very cheaply. But as of current scenarios in the year 2021, The United States was the leading biofuel producer in the world, with production amounting to 1,436 petajoules. Brazil and Indonesia ranked second and third, with figures at roughly 840 and 312 petajoules, respectively. By comparison, Germany’s biofuel production reached around 121 petajoules, placing the country amongst the top five countries in biofuel production, and the leading producer in Europe.
