Carbon Capture, Carbon Capture and Storage (CCS) and Carbon Capture Usage and Storage (CCUS)

Last Updated:

Number of definitions:


Definition 1

Carbon Capture Storage (CCS)  means the use of technology to safely:

(a) capture waste carbon dioxide at the emissions source;

(b) transport the captured carbon dioxide; and

(c) [either use or] permanently store the captured carbon dioxide such that the captured carbon dioxide is not released into the atmosphere.

Definition 2

Carbon Capture Storage (CCS) OR [Carbon Capture Usage and Storage (CCUS)] means the [technology for and] process of capturing, transporting [and using or] storing waste carbon dioxide.

Drafting notes and guidance

The EU's Carbon Capture and Storage ( CCS ) Directive (2009/31/EC) provides that CCS should not serve as an incentive to increase the share of fossil fuel power plants. Its development should not lead to a reduction of efforts to support energy saving policies, renewable energies and other safe and sustainable low carbon technologies, both in research and financial terms.

Lawyers who write and negotiate contracts that provide for CSS or CCUS should raise with clients the need for CCS or CCUS to be a last resort technology, where there is no viable alternative to producing the waste carbon dioxide.

The definitions above can be expanded to refer to the specific technology used or to the underlying industrial process or burning of fossil fuels necessitating CCS or CCUS. For example, the definition could be tailored to:

  • specifically mandate the use of a particular type of CCS technology that provides the best net emissions outcome – for example, ‘pre-combustion capture’ or ‘post-combustion capture’; or
  • refer to capturing waste carbon dioxide emitted in the production of cement or in biomass energy production.
