Scaling - Up Carbon Capture, use and Storage

   Scaling-Up Carbon Capture, Use and Storage

Trapping and storing carbon dioxide(CO2) emission from fossil power generation and industry is needed urgently to achieve carbon neutrality, the UN's Economic Commission Europe (UNECE) said in a report published on wednesday.

The net-zero emission goal is crucial to limit global warming, as outlined in the "Paris Agreement" on the climate changes, and the technology brief calls for repaid scale-up of carbon capture, use and storage(CCUS)  

CCUS

  • CAPTURE: CO2 from processing or burning carbon-emitting substances such as fossil fuels is put through and absorbed by a solvent before it can be emitted via a smokestack. It can later be separated out from the solvent and compressed and liquefied for transport.
  • TRANSPORT: CO2 is typically pumped through a pipeline to get from where it was captured to where it will be stored or used.
  • UTILIZIATION: Captured CO2 can be used to make new products, such as fuels, concrete or even soap.
  • STORAGE: CO2 IS injected deep underground into depleted oil and gas reservoirs. In the process, it can be used to help recover extra oil from aging well. It's stored in the microscopic spaces  in porous rocks. A "Cap Rock" on the prevents it from leaking out again. 

United Nation Economic Commission for Europe(UNECE) stated that deployment of CCUS technology on a large scale would permit the countries to decarbonize these sectors.
