Energy Efficient Carbon Capture and Storage

Tom Baxter, School of Engineering

The UK’s Committee for Climate Change and others have concluded that Carbon Capture and Storage (CCS) is essential if net-zero is to be met by 2050.

This talk focuses on gas-fired power stations combined with CCS. Deploying CCS introduces a large parasitic energy load resulting from the capture and compression system. This reduces power station generation efficiency. Furthermore, gas providers have to deliver additional gas to make up for the energy deficit. This results in additional emissions from the gas-producing assets. Hence, reducing the CCS energy demand has clear benefits.

The equipment and unit operations associated with CCS will be presented together with the quantification of associated energy requirements. Energy-saving opportunities will be discussed and their impact on energy consumption enumerated.
