Fuel Switching to Lower Carbon Fuels at Thermal Power Plants

Detailed overview of innovation with sample startups and prominent university research


What it is

Fuel switching to lower-carbon fuels involves replacing traditional fossil fuels, such as coal and oil, with cleaner alternatives, such as natural gas, biomass, or hydrogen, in thermal power plants. This approach aims to reduce greenhouse gas emissions and air pollution while maintaining reliable electricity generation.

Impact on climate action

Fuel Switching to Lower-Carbon Fuels under Low-Carbon Thermal Power significantly reduces greenhouse gas emissions from power generation. By transitioning from coal or oil to natural gas or renewable alternatives, this innovation lowers carbon intensity, mitigates climate change, and promotes a more sustainable energy mix, aligning with global decarbonization goals.

Underlying
Technology

  • Fuel Handling and Storage: Different fuels have different handling and storage requirements. For example, natural gas requires pipelines or compressed gas storage, while biomass may require specialized storage facilities and handling equipment.
  • Boiler or Combustion System Modifications: Depending on the new fuel, modifications to the boiler or combustion system may be necessary to ensure efficient and clean combustion.
  • Emissions Control: Switching to lower-carbon fuels can reduce emissions, but additional emissions control technologies may still be required to meet environmental regulations.
  • Fuel Supply Chain: A reliable and sustainable supply chain for the new fuel is essential for successful fuel switching.

Prominent Innovation themes

  • Natural Gas Conversion: Converting coal-fired power plants to natural gas can significantly reduce CO2 emissions and air pollution.
  • Biomass Co-firing and Conversion: Co-firing biomass with fossil fuels or converting power plants to run entirely on biomass can further reduce emissions and promote the use of renewable energy sources.
  • Hydrogen Co-firing and Conversion: Hydrogen is a clean-burning fuel that produces only water vapor when combusted. Co-firing hydrogen with natural gas or converting power plants to run entirely on hydrogen can significantly reduce greenhouse gas emissions.
  • Fuel-Flexible Power Plants: Power plants are being designed with fuel flexibility, allowing them to switch between different fuels, such as natural gas and hydrogen, depending on availability and market conditions.
