What Is The Future Of Bio Fuel In India?

Biofuels are fuels produced directly or indirectly from organic material (biomass) including plant materials and animal waste. The most common biofuels used today are ethanol and biodiesel.

In India, ethanol is produced from sugarcane molasses and used as a blending component in gasoline (petrol). Biodiesel is produced from non-edible oilseeds like jatropha and pongamia pinnata (karanja) and blended with diesel. In 2021-22, India consumed 3.25 billion liters of ethanol and 0.27 billion liters of biodiesel.[1]

The Indian government has implemented policies like the Ethanol Blended Petrol Programme and National Biofuel Policy to promote biofuel adoption. Targets include 20% ethanol blending in petrol and 5% biodiesel blending in diesel by 2030.[1]

Benefits of Biofuels

Biofuels offer several benefits compared to conventional fossil fuels. One major advantage is that they are much more environmentally friendly. Biofuels like ethanol and biodiesel burn cleaner than gasoline and diesel, emitting fewer greenhouse gases and air pollutants (https://afdc.energy.gov/fuels/biodiesel_benefits.html). This helps reduce the impact of transportation on climate change and improves public health. Biofuels can often be produced from waste materials, reducing the amount of waste going to landfills.

Biofuels also promote energy security by providing a renewable, domestically produced alternative to imported petroleum. Growing biofuel feedstocks and producing biofuels within a country reduces dependence on foreign oil and mitigates vulnerability to global oil price shocks. This provides greater energy security and insulation from geopolitical conflicts (https://www.epa.gov/environmental-economics/economics-biofuels).

In addition, biofuels spur rural economic development and employment. Cultivating biofuel feedstocks and building biorefineries creates agricultural jobs and investment in rural communities. This provides income sources beyond food production and revitalizes struggling rural economies (https://www.dxpe.com/7-hidden-benefits-of-using-biofuel/).

Challenges Facing Biofuels

India faces several key challenges in expanding its domestic biofuel production and usage. One major issue is the food versus fuel debate. As more agricultural land and crops are diverted towards biofuel production, it reduces the land and crops available for food production. This can potentially impact food security and increase food prices in a country still battling hunger and malnutrition issues (Biofuels and their Challenges in India – Cuts CCIER).

Another challenge is the high production costs of biofuels compared to conventional fossil fuels. Setting up the infrastructure for collecting feedstock, processing into biofuels, and distribution requires major upfront investments. The production costs are further increased in India due to relatively lower crop yields compared to other countries (The Current Status and Key Challenges For Biofuel in India).

There are also concerns around land availability for energy crop plantation, especially with increasing urbanization. Much of India’s marginal and wastelands may not be suitable for intensive biofuel crop cultivation. Ensuring sustainable use of land and water resources is important as biofuel production expands (India Biofuel economy roadmap – Challenges & Prospects).

Biofuel Feedstocks

India has abundant potential for biofuel feedstocks, with sugarcane, jatropha and algae emerging as leading sources for biofuel production.1

Sugarcane is the primary feedstock for ethanol production in India, accounting for over 90% of ethanol produced. India is the world’s second largest producer of sugarcane, after Brazil. Existing sugarcane production and processing infrastructure contributes to low production costs for sugarcane-based ethanol in India.2

Jatropha is a drought-resistant, non-edible oilseed plant that can be grown on marginal and degraded lands unsuitable for food production. Jatropha oil has been identified as an excellent feedstock for biodiesel production. However, large-scale jatropha cultivation has faced challenges such as low yields and lack of planting material.1

Algae is an emerging feedstock with high oil yields compared to conventional crops. Algae can be grown using non-arable land and non-potable water resources. R&D is ongoing to develop viable technologies for mass cultivation and oil extraction from algal biomass in India.2

Biodiesel Production and Usage

India has rapidly expanded its biodiesel production capacity over the past decade. According to Statista, the production volume of biodiesel in India was 185 million liters in 2022, forecast to increase to 200 million liters in 2023[1]. Companies like Aemetis have invested in large biodiesel plants, with Aemetis completing an expansion to increase annual production capacity to 60 million gallons at their plant in India[2].

The Indian government has implemented biodiesel blending mandates to spur domestic production and usage. In 2018, the blending requirement for biodiesel was increased from 5% to 10% by volume for transportation fuels. However, challenges with consistent supply and distribution infrastructure have prevented the full blending target from being achieved so far.

Biodiesel is primarily used in transportation applications in India. It can be blended with conventional diesel and used in diesel vehicles without engine modifications. Initial adoption focused on government and public transportation fleets in major cities. But increased production is expected to support broader consumer vehicle use going forward.

Ethanol Production and Usage

India’s ethanol production capacity has rapidly expanded in recent years to meet the government’s blending targets. As per the Ethanol Booklet 2023 published by Bharat Petroleum, ethanol production capacity reached 6.5 billion liters per year as of December 2022, up from just 1.5 billion liters in 2013 [1]. Most ethanol production comes from molasses, a byproduct of sugar production. However, in December 2022, the government permitted diversion of up to 1.7 million tons of sugar for ethanol production in 2023 to further increase supply [2].

To boost ethanol blending, the government has set targets of 10% blending by 2022 and 20% blending by 2025 under the Ethanol Blending Programme. As of December 2022, India has achieved 10% blending across the country, up from just 1.53% in 2013. All gasoline sold in India now contains 10% ethanol.

This has increased ethanol consumption for vehicle use. According to government data, ethanol consumption reached 3.5 billion liters in 2021-22, up from just 0.38 billion liters in 2013-14. With 20% blending target, annual ethanol consumption could reach 7.2 billion liters by 2025.

Advanced Biofuels

Advanced biofuels, also known as second generation biofuels, are produced from non-food crops like agricultural residues, woody biomass, and municipal waste. These fuels provide environmental benefits and don’t compete with food production like some first generation biofuels made from food crops like corn and sugarcane.

One key advanced biofuel is bio-jet fuel made from materials like jatropha, camelina, and algae. Major airlines in India including SpiceJet and IndiGo have started using blended bio-jet fuels on some flights. Bio-jet fuels have the potential to reduce aviation emissions and reliance on fossil fuels. However, production costs remain high (IEA).

Biobutanol is another advanced biofuel that can be produced from agricultural waste products through fermentation by microorganisms. Compared to ethanol, biobutanol has a higher energy content and can be blended with gasoline at higher ratios. Companies like Gevo and Butalco are developing biobutanol production technologies, but commercialization remains limited (DBT India).

While advanced biofuels show promise, more research and investment is needed to improve production processes and drive down costs. Government policies that support commercialization will be key to realizing their potential in India.

Government Policy

The Indian government first introduced the National Policy on Biofuels in 2009 to promote the development and utilization of biofuels. This policy has since been updated through amendments in 2018 and 2022.

The policy aims to meet the blending targets for ethanol and biodiesel, encourage production through subsidies and incentives, and establish coordination between ministries for the procurement, blending and marketing of biofuels.

Some key aspects of India’s biofuel policy include:

Ethanol blending target of 20% by 2025 and 20% biodiesel blending by 2030
Differential pricing for ethanol based on feedstock used
Financial assistance and subsidies for 2G ethanol projects

Tax incentives for biodiesel production
Mandates for certain industries to use biodiesel

The 2022 amendments introduced additional incentives such as interest subvention for grain-based distilleries, viability gap funding for 2G ethanol projects, and expansion of feedstocks for ethanol production beyond molasses and sugarcane juice.

The policy aims to balance the interests of farmers, industry and consumers while meeting India’s energy security and climate change goals through greater adoption of biofuels.

Private Sector Investment

Major companies involved in biofuel production and research in India include Reliance Industries, IOCL, HPCL, BPCL, Praj Industries, and Abellon CleanEnergy.[1] Oil marketing companies are investing in ethanol production from sugarcane and biodiesel production from non-edible oil seeds.[1]

India’s emphasis on biofuels has created business opportunities in feedstock supply, technology providers, project developers, biofuel production, distribution and blending infrastructure, and manufacturing equipment.[2] Many startups are emerging in 2nd and 3rd generation biofuel technologies using agriculture waste, municipal solid waste, and algal feedstocks.[3]

Major areas of startup and small business innovation include biofuel production from lignocellulosic biomass, microbial conversion, gasification and pyrolysis technologies, new feedstocks like algae and seaweeds, and enzymatic catalysis.[1] Startups can help drive development of next generation biofuels.

Future Outlook

India has set ambitious targets for biofuel production and consumption by 2030. The government aims to achieve 20% ethanol blending in petrol and 5% biodiesel blending in diesel by 2030 [1]. To meet these targets, ethanol production is projected to reach 10 billion liters and biodiesel production is expected to reach 5 million metric tons by 2030 [2].

A SWOT analysis of India’s biofuel sector shows strengths in abundant feedstock availability, government support through policies, and growing private sector investments. Weaknesses include high production costs compared to fossil fuels, lack of infrastructure for distribution and blending, and concerns about food security from using food crops as feedstock. Opportunities lie in meeting rising energy demands through renewable sources, reducing oil imports and fuel costs, boosting rural economies, and mitigating climate change. Threats include competition from other renewable energy sources, lack of sustained government policy support, and concerns about engine compatibility and land use changes.

Key challenges ahead include securing adequate feedstock supplies, minimizing food vs fuel issues, reducing production costs, building ethanol distillation and biodiesel production capacity, setting up distribution infrastructure, and increasing flex-fuel vehicles. If these challenges can be properly addressed, India has the potential to build a thriving biofuel industry that contributes to the country’s energy security and sustainability.
