The terms carbon capture and storage (CCS) and carbon capture, utilization, and storage (CCUS) are closely related and often used interchangeably. [3] Both terms have been used predominantly to refer to enhanced oil recovery (EOR) a process in which captured CO 2 is injected into partially-depleted oil reservoirs in order to extract more oil. [3]
The United States Geological Survey (USGS) defines carbon sequestration as follows: "Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide." [3] Therefore, the difference between carbon sequestration and carbon capture and storage (CCS) is sometimes blurred in the media.
The Petra Nova project is a billion dollar endeavor undertaken by NRG Energy and JX Nippon to partially retrofit their jointly owned W.A Parish coal-fired power plant with post-combustion carbon capture. The plant, which is located in Thompsons, Texas (just outside of Houston), entered commercial service in 1977. Carbon capture began on 10 ...
Many of these techniques existed before World War II and, consequently, post-combustion capture is the most developed of the various carbon-capture methodologies. Post-combustion capture plant should aim to maximise the capture of CO 2 emissions from combustion plant and delivery it to secure sequestration in geological strata. [ 1 ]
Burning peatlands is a major cause of carbon emissions, releasing carbon dioxide and other greenhouse gases which contribute to climate change. These peat fires are responsible for up to 5% of the world's total annual emissions, as well as significant air pollution that can have serious health implications on local communities.

Direct air capture (DAC) is the use of chemical or physical processes to extract carbon dioxide (CO 2) directly from the ambient air. [1] If the extracted CO 2 is then sequestered in safe long-term storage, the overall process is called direct air carbon capture and sequestration (DACCS), achieving carbon dioxide removal.
