Biofuel is a type of hydrocarbon fuel that is created either directly or indirectly from organic material. They serve as alternatives to traditional fuels, which are fossil fuels. Ethanol and biodiesel are the two most popular biofuels currently in use. Promoting the use of biofuels in transportation in nations like India will assist in lowering the cost of importing crude oil. New cash crops derived from biofuels can also aid in rural and agricultural development. In India, according to the Biodiesel Purchase Policy, the petroleum industry must purchase biodiesel. 9 States and 4 Union Territories must blend 5% ethanol with gasoline as of January 1, 2003, as per the Ethanol Blending of Gasoline Mandate. This article will explain to you the Promotion of Biofuels which will be helpful in preparing the Environment Syllabus for the UPSC Civil Service exam.

Biofuels - Categories

First Generation Biofuels

• These are produced using traditional technologies from food sources including sugar, starch, vegetable oil, or animal fats.
• Bioalcohols, Biodiesel, Vegetable Oil, Bioethers, and Biogas are examples of typical first-generation biofuels.
• Although the conversion process is simple, using food sources to produce biofuels upsets the food system, driving up food costs and contributing to hunger.

Second Generation Biofuels

• These are made from non-food crops or by-products of food crops that are considered wastes since they cannot be eaten, such as fruit peels, husks, stems, and wood chips.
• Such fuels are created through thermochemical reactions or biochemical conversion processes.
• Examples include biodiesel and cellulose ethanol.
• Although these fuels have no impact on the food economy, they are difficult to produce.
• Additionally, compared to first-generation biofuels, it is claimed that these biofuels release fewer greenhouse gases.

Third Generation Biofuels

• These are made from microscopic organisms like algae.
• Butanol is an excellent example of third-generation biofuels.
• Algae can be cultivated on land and in water that is not suited for food production, which relieves pressure on already-depleted water supplies.
• One drawback is that the fertilizers used to grow these crops pollute the environment.

Fourth Generation Biofuels

• Crops that have been genetically modified to absorb large amounts of carbon are cultivated and harvested as biomass in the creation of these fuels.
• Then, utilizing second-generation processes, the crops are transformed into fuel.
• Pre-combustion of the fuel occurs, and carbon is captured.
• The carbon is then geo-sequestered, which refers to the storage of the carbon in coal seams that cannot be mined or in exhausted oil or gas fields.
• Some of these fuels are regarded as carbon-negative because they remove carbon from the environment during production.

Biofuels - Advantages

• Renewable Source: Biofuels are renewable because they are made from biomass.
• Source Material: Biofuels can be produced from a variety of materials, including crop waste, manure, and other wastes, whereas oil is a finite resource that originates from a limited number of sources.
• Environment Pollution: Although biofuels don't emit as much carbon as fossil fuels do, the fertilizers that are needed to grow them produce greenhouse gases. Additionally, biofuels can assist in controlling municipal solid waste by allowing garbage to be turned into fuel.
• Security: Local biofuel production reduces the country's reliance on imported energy and increases security. Countries can preserve the integrity of their energy resources and keep them secure from outside influences by limiting their reliance on foreign fuel sources.
• Economic Stimulation: Since biofuels are made close to home, factories that make them can hire hundreds or thousands of people, bringing new jobs to rural communities. Demand for appropriate biofuel crops will rise as a result of biofuel production, stimulating the economy of the agriculture sector.

Biofuels - Disadvantages

• Efficiency: Compared to some biofuels, fossil fuels yield more energy. For instance, ethanol produces less energy per gallon than gasoline does per gallon (a fossil fuel).
• Cost: Extraction of fossil fuels from the earth is a challenging and expensive operation, which results in high costs. The land is needed for the production of biofuels, which affects both their price and the price of food crops.
  • Additionally, even while farmers can benefit financially from planting transgenic biofuel crops, too many of these crops have the potential to destroy biodiversity.
• Food Shortages: Concerns have been raised about the possibility of food shortages and price increases as a result of the use of important acreage for fuel crops.
• Water Use: Proper irrigation of biofuel crops and the production of the fuel require enormous amounts of water, which may put a burden on local and regional water supplies.

Promotion of Biofuels in India

National Policy on Biofuels 2018

• The Ministry of Petroleum and Natural Gas notified the National Policy on Biofuels in 2018, superseding the National Policy on Biofuels published by the Ministry of New and Renewable Energy in 2009.
• MNRE has set an indicative target of 20% blending of ethanol in petrol and 5% blending of biodiesel in diesel to be achieved by 2030.
• The Ministry has also outlined a roadmap for the efficient realization of the policy which entails the following steps:
• Improve the current production of ethanol and biodiesel by increasing domestic production;
• Set up second-generation (2G) biorefineries;
• Develop new feedstock for biofuels;
• New technological developments to improve biofuel production;
• Facilitate the blending of biofuels with conventional fuels.
• To enable the extension of appropriate financial and fiscal incentives under each category, the Policy categorises biofuels as "Basic Biofuels" - First Generation (1G) bioethanol and biodiesel - and "Advanced Biofuels" - Second Generation (2G) ethanol, Municipal Solid Waste (MSW) to drop-in fuels, Third Generation (3G) biofuels, bio-CNG, etc.
• The Policy encourages the establishment of supply chain mechanisms for the production of biodiesel from non-edible oilseeds, used cooking oil, and short gestation crops.
• The Policy also outlines the roles and responsibilities of all relevant Ministries/Departments in terms of biofuels.
• It broadens the range of raw materials available for ethanol production by allowing the use of sugarcane juice, sugar-containing materials such as sugar beets and sweet sorghum, starch-containing materials such as corn and cassava, damaged food grains such as wheat, broken rice, and rotten potatoes for ethanol production.
• With the approval of the National Biofuel Coordination Committee, the Policy allows the use of surplus food grains for the production of ethanol for blending with gasoline.
• With a focus on Advanced Biofuels, the Policy proposes a Rs. 5000 crore viability gap funding scheme for 2G ethanol Bio refineries over 6 years, in addition to additional tax breaks and higher purchase prices than 1G biofuels.

What is Ethanol Blending Programme (EBP)?

• In January 2003, the EBP initiative was initiated to provide 5 per cent ethanol mixed gasoline.
• The program aimed to promote the use of alternative and environmentally beneficial fuels while also reducing energy import dependency.
• OMCs should continue to prioritize ethanol production from:
• sugarcane juice/sugar/sugar syrup
• B-heavy molasses
• C-rich molasses
• contaminated cereals and other sources
• With effect from April 1, 2019, this initiative has been extended to all of India, save the UTs of the Andaman Nicobar and Lakshadweep islands, where OMCs sell fuel blended with ethanol up to 10%.

Biofuels Related National Initiatives

• Pradhan Mantri JI-VAN Yojana, 2019: This program was launched to promote R&D in the 2G ethanol sector and to build an ecosystem for the establishment of commercial initiatives.
• GOBAR (Galvanizing Organic Bio-Agro Resources) DHAN Scheme: It focuses on managing and turning solid farm waste, like animal dung, into compost, biogas, and bio-CNG, which helps keep villages clean and boosts the income of rural people.
• Repurpose Used Cooking Oil (RUCO): The Food Safety and Standards Authority of India (FSSAI) launched it with the intention of creating an ecosystem that would make it possible to collect leftover cooking oil and turn it into biodiesel.

Biofuels Related Global Initiatives

• Roundtable on Sustainable Biomaterials (RSB): It is an international initiative that brings together parties with an interest in the sustainability of biofuel production and distribution, including farmers, businesses, governments, non-governmental organizations, and scientists.
• It introduced the "RSB Certification System," a set of comprehensive sustainability standards, in April 2011. Producers of biofuels that adhere to these standards can demonstrate to consumers and government officials that their product was produced without endangering the environment or violating human rights.
• Sustainable Biofuels Consensus: Governments, the commercial sector, and other stakeholders are encouraged by a global initiative to act swiftly to secure the sustainable trading, production, and use of biofuels.
• Bonsucro: It was founded in 2008 as a global, non-profit, multi-stakeholder organization to support sustainable sugar cane. With the recognition of the requirement for economic viability, it aims to lessen "the environmental and social consequences of sugarcane production."

Conclusion

The ability of biofuel to reduce greenhouse gas emissions varies greatly, with some scenarios having emissions that are lower than those from fossil fuels and others having negative emissions. In order to lessen reliance on petroleum, the International Energy Agency expects biofuels to supply more than a quarter of the global demand for transportation fuels by 2050. The IEA's sustainable development target, however, is not being met by the production and use of biofuels. To meet the IEA target, the worldwide biofuel output must rise by 10% between 2020 and 2030.
