Note that additional commentary on the issues discussed in this Practice Note in the context of the regulation, consenting and incentivisation of the net zero energy transition is available in the following textbook that we have published: Collinson and Hockman on Energy Law: Regulating, Consenting and Incentivising the Energy Transition. What is carbon capture, usage and storage (CCUS)? CCUS is sometimes referred to as ‘carbon capture and storage’ (CCS), which is, broadly, a more narrow subset of the same industry. CCS refers to a variety of processes which capture and store CO2 emissions from industrial activities. CCS generally involves the following steps: • capturing CO2 generated by industrial processes (or removing unavoidable and/or historic CO2 directly from the air, also referred to as ‘Direct Air Carbon Capture’ (DACC) and compressing it to a liquid state • transporting the CO2 (usually via pipelines, which may include re-purposed natural gas pipelines) to deep underground geological storage points, eg rock formations, depleted oil and gas reservoirs
