Carbon Abatement Technologies (CATs)

The combustion of fossil fuels produces greenhouse gases like Carbon Dioxide (CO2) Nitrogen Oxide (NOx) and other harmful gases such as Sulphur Dioxide (SO2). CO2 is the main gas that causes climate change. Fossil-fuel based CATs are a group of technologies that enable fossil fuels to be used with substantially reduced CO2 emissions, and therefore can be part of the solution to climate change. By enabling continued use of fossil fuels within our emissions targets, CATs can also strengthen the diversity and security of energy supply.

CATS include a range of generic options, including:

  • Higher efficiency conversion process to reduce the amount of fuel consumed and the associated CO2 emissions. This can contribute to emission reductions of 10 – 30%
  • Fuel switching to lower carbon alternatives – such as natural gas and co-firing with 5-10% CO2 neutral biomass
  • Carbon Capture and Storage with the potential to reduce emissions by 85-90%

The UK’s Carbon Abatement Technologies: Strategy addresses the future requirements for reducing CO2 emissions from fossil fuel power generation and is intended to ensure that the UK takes a leading role in the development and commercialisation of CATs that can make a significant and affordable reduction in CO2 emissions from fossil fuel use.

Carbon Capture and Storage (CCS) is a radical type of CAT which has great potential for climate change mitigation.
