By Corbin Hiar, CLIMATEWIRE | That’s distinct from typical applicants for Department of Energy funding programs, experts say. It is largely due to the emerging nature of direct air capture technology — a collection of fans, filters and piping that removes carbon dioxide from the atmosphere and stores it permanently underground or in long-lasting products like concrete.
There are less than two dozen DAC facilities in operation worldwide, but that could sharply increase when DOE awards $3.5 billion to help build massive DAC hubs in the United States. Scientists believe DAC and other carbon removal technologies need to rapidly deploy in the coming years to avoid damaging levels of global warming that could cause extreme heat waves, disastrous flooding and lead to the collapse of food systems.
DOE plans to make its initial DAC hub selections around the end of next month. Other groups that have said they are competing for the matching funds include industrial conglomerate General Electric, geothermal startup Fervo Energy and the DAC company Global Thermostat.
