The process of carbon capture and storage (CCS) refers to the isolation of carbon dioxide from generation by gas or coal-fired generation and storing it rather than discharging it to the atmosphere. The CO2 is extracted and piped to a storage facility. This may be a partially depleted oil field where it is used to facilitate enhanced oil recovery (EOR). Figure 7.1 shows a typical installation where the natural gas is fed into a reformer and capture plant where it is separated into CO2 and hydrogen using specially developed membranes. The CO2 is pumped into the offshore oilfield to enhance oil recovery or an offshore aquifer. The remaining hydrogen fuels a gas-fired power station producing clean electricity without CO2 emissions.
