The boom in carbon removal, whether from the air , what is called direct air capture (DAC) or from industrial point sources , what is called carbon capture and storage (CCS), cannot come fast enough. The UN-backed Intergovernmental Panel on Climate Change (IPPC) assumes that if Earth is to have a chance of warming by less than 2°C above pre-industrial levels, renewables, electric vehicles and other emissions reductions are not enough. Carbon Capture and Storage (CCS)and sources of “negative emissions” such as DAC must play a part. The US Department of Energy calculates that America’s climate targets require capturing and storing between 400m and 1.8bn tonsof CO2 annually by 2050, up from 20m tons today. ..
For years DAC and CCS projects were regarded as technically plausible, perhaps, but uneconomical but carbon capture, utilization and storage (CCUS) may attract $150bn in investments globally this decade. A factor behind the recent flurry of carbon-removal activity is government action. One obvious way to promote the industry would be to make carbon polluters pay a high enough fee for every ton of carbon they emit that it would be in their interest to pay carbon removers to mop it all up, either at the source or from the atmosphere….The emerging view among technologists, investors and buyers is that carbon removal will develop like waste management did decades ago—as an initially costly endeavor that needs public support to get off the ground but can in time turn profitable…
Maybe the biggest sign that the carbon-removal business has legs is its embrace by the oil industry. Occidental is keen on DAC. ExxonMobil says it will spend $17bn from 2022 to 2027 on “lower-emissions investments”, with a slug going to CCA…Equinor and Wintershall, a German oil-and-gas firm, have already secured licenses to stash carbon captured from German industry in North Sea sites. Hugo Dijkgraaf, Wintershall’s technology chief, thinks his firm can abate up to 30m tons of CO2 per year by 2040. The idea, he says, is to turn “from an oil-and-gas company into a gas-and-carbon-management company”.
