3 Capture, transport and storage of CO2 in BECCS systems
CO2 is not only a greenhouse gas, but is also used in many industrial applications. Best known to the layman is perhaps the CO2 used for forming bubbles in soft drinks, but CO2 is also used in fire extinguishers, as a refrigerant in the food industry, and in the production of artificial fertilizers and other chemicals. Due to the wide range of applications for CO2, extensive knowledge of how to store, handle and transport CO2 has been acquired in the industrial world.
BECCS shares to a large extent technological components with fossil fuel CCS, but has different compositions of CO2 and other gases in flue streams as well as a smaller scale of operations. This creates a set of demands that are unique to BECCS, both in relation to fossil fuel CCS and industrial applications.
