As a source of low-carbon power, CCS can’t compete on economics with wind and solar.ĬCS is a new technology, and costs tend to fall as new technologies are deployed and develop. A new solar PV or wind plant is between half and a third the price of a new coal unit with CCS and emits zero CO 2. Coal plants that capture and store 90% of their carbon emissions cost nearly two-thirds more than an equivalent coal plant without CCS to produce the same amount of electricity. costs more than onshore wind and solar PV per unit of electricity it generates. Energy InnovationĮven without CCS, a new coal plant in the U.S. Levelized generation costs of coal, coal with CCS, onshore wind and solar PV plants. Additional costs come from building pipelines to transport the CO 2, injecting it underground, and monitoring the injection site. Since a considerable amount of energy is required to extract, pump, and compress CO 2, a plant with CCS must also purchase and burn more fuel to produce the same amount of electricity as a plant without CCS. is already quite high, about $92 per megawatt-hour ), a coal plant with CCS requires additional equipment, increasing upfront construction costs, and has additional operations and maintenance (O&M) expenses. In addition to the costs of an ordinary coal-fired power plant (which in the U.S.

The largest problem facing CCS today is cost. Perhaps unsurprisingly, many of the world’s largest oil and gas companies recently invested $1 billion in CCS research. It holds out the promise that we can continue to burn fossil fuels, potentially in large quantities, without negative climate change impacts. Scottish Carbon Capture and StorageĬCS is a favorite emissions reduction option for many politicians and coal companies because it does not involve transitioning to a different electricity source (such as wind, solar, or nuclear power). being storaed under the sea floor, it may also be stored beneath land.
