Tech firms, oil companies and the U.S. government are investing billions of dollars in carbon capture technology to suck greenhouse gases out of the atmosphere. Can it save the warming world?

Her dad, Klaus Lackner, happened to be a physicist working on nuclear fusion at Los Alamos National Laboratory.
But Samala was growing concerned about climate disasters, including in India. The 2018 report by the Intergovernmental Panel on Climate Change , which for the first time said carbon removal would probably be required to keep global warming to 1.5 degrees C, convinced him that “there is no future of the planet” without the technology. Two years later heHeirloom with Noah McQueen, a chemical engineering Ph.D. student.
Alongside equipment, energy is the main cost. The million-metric-ton Project Cypress will consume as much electricity as 230,000 U.S. homes. Removing a billion metric tons would require up toto meet its renewable-energy goals. Critics have argued that investments in DAC would be better spent on replacing natural gas and coal power, which still generatein the atmosphere over two decades than replacing a coal plant with that same wind power, according to a 2019by Mark Z.
But Emily Grubert, a University of Notre Dame sociologist who previously worked for the DOE on DAC hubs, says “paying the oil companies to stop doing oil” is fruitless. She and others argue that the carbon-removal industry should be nationalized, with the government limiting emissions and paying for capture, akin to municipal garbage collection for the atmosphere. Activists such as Ozane have called for the hubs to be at least partially owned by communities.
