Why in news?

India has launched the Global Biofuel Alliance in G20 summit 2023, demonstrating its commitment to climate action with global cooperation.

Global Biofuels Alliance

  • About- It is an initiative to develop an alliance of governments, international organisations and industry to facilitate the adoption of biofuels.
  • OriginIndia, Brazil, United States will work together for the development of alliance
  • Brazil, India and the US contribute about 85% of the world’s biofuel production.
  • 19 countries and 12 international organisations have joined the GBA
  • Aim- To facilitate cooperation and intensify the use of sustainable biofuels, including in the transportation sector.
  • It will place emphasis on
    • Strengthening markets, facilitating global biofuels trade and developing concrete policy lesson-sharing
    • The already implemented best practices and success cases.
  • It will work in collaboration with the relevant existing agencies as well as initiatives such as
  • The Clean Energy Ministerial Bio-future Platform,
  • The Mission Innovation Bioenergy initiatives, and
  • The Global Bioenergy Partnership (GBEP)

What is Biofuel?

  • Biofuels are liquid fuels produced from renewable biological sources, including plants and algae.

Generation

Source

Example

First generation (1G)

Conventional source or food sources - Sugarcane, corn etc.,

Bioethanol, biodiesel, biogas

Second generation (2G)

Non-food sources and the waste left from the food resources-  Municipal solid waste, wood chips etc.,

Cellulose ethanol, biodiesel

Third generation (3G)

Algae- It consists of 40% of lipids which can be converted to biodiesel or synthetic petroleum.

Butanol, Gasoline, Jet fuel

 

Fourth generation (4G)

Produced from genetically engineered bio algae

What is the significance of Biofuel?

  • Eco-friendly- It is alternative to the fossil fuel which is a non-renewable source.
  • Reduce emission- It have gained worldwide popularity, contributing to meet net zero carbon emission targets.
    • Reports say that ethanol reduces Greenhouse Gas Emissions (GHG) up to 65%.
  • Reduce import bill- It help in reducing energy imports, on which the country depends for a large part of its oil and natural gas requirements.
  • Fuel economy- Vehicles that run on biodiesel get 30% better fuel economy than gasoline-powered vehicles.
  • Economic development- International Food Policy Institute (IFPI) has said that ethanol made from a shrub called cassava can help reduce poverty in that West African nation where 80% of the labour force is farmers.
  • Sustainable biofuel- They are produced from crop residues and other wastes, with low water and GHG footprint

What are the challenges faced by India?

  • Dependence on 1G- The policy target in India of achieving 20% ethanol blending with petrol (E20) by 2025-26 is expected to be met almost entirely by 1G ethanol made from sugar cane and food grains.

  • Supply chain bottlenecks- 2G is unlikely to contribute much to achieving E20 target due to several challenges related to feedstock supply chain and scaling up
  • Food security- India’s crop yields have already stagnated, and global warming is expected to reduce yields, India’s strategy to meet blending targets cannot depend on surplus crop production.
  • Groundwater depletion- Recent study led by the University of Michigan projected that the rates of groundwater depletion could triple during 2040-81 compared with the current rate.
  • Increase in GHG emissions- Increasing GHG emission from the agriculture for fuel production is not sustainable option.
  • Reliance on sugarcane- It is a remunerative crop that has more to do with government intervention than anything else.
  • Economies of scale- Balancing economies of scale with the energy needs and costs of biomass collection and transportation across large distances is major challenge.

What lies ahead?

  • Prioritise Biomass- The Energy Transitions Commission, in its report on ‘Bio resources within a Net-Zero Emissions Economy’, recommended that biomass should be prioritised for use in sectors where there are limited low-carbon alternatives.
  • Net zero emission- According to the International Energy Agency, to achieve net-zero emissions by 2050 globally, sustainable biofuel production needs to triple by 2030 to fuel modes that have few other mitigation options.
  • Sustainable fuel- Although 1G ethanol is unlikely to fit the bill, 2G ethanol could be counted as a sustainable fuel, especially if the production is decentralised, i.e., crop residues do not have to be transported large distances to a central manufacturing plant.
  • Innovation- The Global Biofuels Alliance could help drive innovation and technology development in establishing an efficient biomass supply chain and smaller-scale decentralised biofuel production units.

Steps taken by India to promote Biofuel Production

  • E5 program- It was India’s pilot project of 5% ethanol belnding.
  • National Biodiesel Mission- It was formulated in 2003 to achieve 20% biodiesel blend by 2011-12.
  • National Policy on Biofuel- It was launched in 2009, proposed a non-mandatory target of 20% blending of both biodiesel and bioethanol by 2017.
  • The policy is revised in 2018 to achieve 20% bioethanol blending and 5% biodiesel blending by 2030.
  • GST- Goods & Service Tax (GST) on ethanol meant for EBP Programme has been reduced from 18% to 5%.
  • SATAT scheme- Sustainable Alternative towards Affordable Transportation Initiative (SATAT) encourages entrepreneurs to set up CBG plants, produce & supply CBG to Oil Marketing Companies (OMCs) for sale as automotive & industrial fuels.
  • PM JI-VAN Yojana- It was launched in 2018 to provide Viable Gap Funding for 2G bioethanol.
