S966 - Carbon Capture and Storage

Description

“Carbon Capture and Storage” Engineering the Future evidence, led by the IET, to the Energy and Environment Select Committee


Abstract

There are three main components to CCS: the capture, transport and storage of CO2. All three use proven technologies that have been demonstrated independently in different industries. The three have not yet been implemented together in an end-to-end system in the power sector.  All of the CCS technologies currently available will impose an efficiency penalty, effectively requiring approximately 10-15% more fuel to be burned in gas-fired power plants and 20-25% in coal-fired power plants to produce the same amount of electricity.  The key barrier for CCS technology is that, to date, there have been insufficient economic reasons for companies to develop and implement it, or even to undertake the demonstrations necessary to bring the technology to maturity.

However, the potential advantages are greater diversity of supply and maintaining some of the flexibility that fossil fuelled plant provides. A largely decarbonised electricity sector (consisting of nuclear, renewables and CCS, combined with energy storage and demand response) is technically achievable.  Without CCS, the UK would need a lot more nuclear if it is to meet greenhouse gas (GHG) targets.

This evidence is submitted on behalf of Engineering the Future.  Its development has been led by The Institution of Engineering and Technology and it is supported by The Energy Institute, The Institution of Chemical Engineers, The Institution of Mechanical Engineers and the Royal Academy of Engineering.
