The Energy Gang

Direct air capture and carbon sequestration – is it viable, and scalable?The U.S. Department of Energy announced in late August that it would be investing $1.2 billion in two direct air capture or DAC facilities. Direct air capture technology, which uses either chemical media (such as a liquid solvent or solid sorbents) or physical processes involving filters to remove C02 directly from the atmosphere. Carbon capture technologies - that capture CO2 at emissions point sources, like power plants or steel making - is also an area the DOE will be supporting for demonstration projects.Some environmentalists have sharply criticized the Biden administration for providing financial support for DAC and CCS technologies, arguing not only is the technology expensive and unproven, but that it serves as a false flag mechanism by the oil and gas industry to sanction them to continue emitting greenhouse gases.So should the government be investing billions in these technologies? Can CCS and DAC play a role in decarbonizing h
