  1. Promoting Emerging Technologies

National Green Hydrogen Mission: This flagship mission aims to make India a global hub for green hydrogen production, a clean fuel with the potential to decarbonisehard-to-abate sectors like:

  • Steel Production: Green hydrogen can replace coal in steel-making, significantly reducing carbon emissions. Pilot projects are being undertaken to explore the feasibility of this technology.
  • Fertiliser Production: Green hydrogen can produce ammonia, a key fertiliser ingredient, without releasing greenhouse gases. Research institutions like The Energy and Resources Institute (TERI) are exploring this possibility.
  • Heavy-Duty Transportation: Green hydrogen fuel cell trucks have the potential to revolutionise long-haul transportation, reducing emissions compared to traditional diesel trucks.

Carbon Capture, Utilization, and Storage (CCUS): Research and development efforts are underway to explore CCUS technologies. These technologies capture carbon emissions from power plants and industrial facilities, preventing them from entering the atmosphere. Captured carbon could be utilised for various purposes or safely stored underground. The Indian Institute of Technology Delhi (IIT Delhi) is leading research projects on developing efficient and cost-effective CCUS technologies suitable for Indian conditions.

  1. Market Mechanisms and Incentives
  • Perform, Achieve, and Trade (PAT): Implemented as a pilot program, PAT incentivisesenergy efficiency improvements in industries through tradable Energy Savings Certificates (ESCerts). Industries exceeding their energy efficiency targets can trade ESCerts, creating a market for energy efficiency. As of 2023, over 500 industrial units participated in the PAT scheme, achieving cumulative energy savings of 8 million metric tonnes of CO2 equivalent.
  • Green Procurement: With its substantial purchasing power, the government promotes low-carbon materials like steel and cement through green procurement policies. By 2022, 30% of government procurement contracts were awarded based on environmental criteria, stimulating demand for low-carbon products and enabling innovation in sustainable manufacturing.
  1. Challenges and Considerations

Despite policy efforts, many low-carbon technologies struggle to compete economically with traditional alternatives. Increased carbon prices or targeted production subsidies are essential to make these technologies commercially viable. For instance, subsidies for renewable energy generation reached $150 billion globally in 2023, driving down costs and increasing adoption rates.

Effective enforcement and long-term policy clarity are critical for market mechanisms to succeed. Inconsistent enforcement undermines carbon market integrity. A clear and stable policy framework is essential; for example, the EU’s carbon pricing mechanism has reduced emissions by 42% since 1990, demonstrating the effectiveness of stringent and sustained policy implementation. Overall, the Indian government’s policy framework is multifaceted, both established and emerging decarbonization technologies.
