Background
Gas-fired power generation currently accounts for around 20% of global electricity production capacity and in the past twenty years it has been a popular choice for new power generation capacity, particularly in many developed countries, due to its high efficiency, low installed costs and good reliability and flexibility. Interest in natural gas fired power generation has increased recently because of the increasing availability of natural gas from shale and greater concerns about nuclear power in some countries.
A switch from coal to gas can help to reduce emissions from power generation substantially but it is not a CO2-free generation option. In the longer term it is likely that new gas fired power plants will be required to be built and operated with CO2 capture and storage (CCS) technology to achieve deep reductions in emissions. Most of the work on CCS has so far concentrated on coal and relatively little information on the performance and costs of gas fired power plants with CCS has been published. IEAGHG has therefore commissioned Parsons Brinckerhoff to undertake this techno-economic study on CO2 capture at natural gas fired power plants. . |
