Feasibility Study on the Transmission of CO2
GASTEC at CRE (GaC)
GASTEC at CRE Limited (GaC) was commissioned by The IEA Greenhouse Gases R&D Programme (IEAGHG) to undertake a feasibility study to assess the economic and practical viability of a distributed carbon dioxide collection and transmission network.
It has been well documented that the capture and storage of CO2 from fossil fuel power plant and other major industrial processes offers one route to major reductions in greenhouse gas emissions. Collection of CO2 from large point sources is attractive because of the large economies of scale that can be achieved, and the relative simplicity of the transmission system. However, there remain a significant proportion of CO2 emissions which derive from the industrial and commercial sectors which is distributed. Most recent studies have concentrated on centralised CO2 collection and disposal, possibly coupled with distribution of ‘clean’ energy in the form of electricity or hydrogen to the smaller, decentralised sources. However, such a strategy would still require an extensive distribution network and has not been compared to the alternative of decarbonisation at the point of consumption combined with distributed collection and transmission of CO2 .
In order to formulate designs for the distributed collection system, three distinct levels of collection were considered.
