The Carbon Jigsaw

摘要

Carbon capture and storage(CCS)has yet to live up to the hype.But it is enjoying a renaissance among companies seeking to keep oil and gas a key part of their businesses during the energy transition.Qatar Petroleum,for example,is maldng CCS a major element of its LNG mega-expansion,while Exxon Mobil is also embracing the technology(p3).The focus has shifted to advancing next-generation CCS technologies rather than spend billions on more commercial-scale projects(WGI Feb.17'21).Right now,roughly 65 operational,planned or under-construction developments globally are capturing about 40 million tons of carbon dioxide per year.For CCS to play a major role in decarbonization,it would need to scale up massively.Anywhere from 350-1,200 gigatons would have to be captured and stored by 2100 to meet the UN Intergovernmental Panel on Climate Change's(IPCC)goal of keeping warming to 1.5°C.
