U.S. unveils plans for large facilities to capture carbon directly from air

Excerpt: The U.S. Department of Energy (DOE) today announced it will spend $1.2 billion for two pioneering facilities—one in Texas, the other in Louisiana—that will remove millions of tons of carbon dioxide (CO2) annually from the atmosphere using a technology known as direct air capture (DAC). Part of a controversial effort to combat global warming, the awards represent the first phase of $3.5 billion in funding for DAC hubs set aside in last year’s Bipartisan Infrastructure Law and mark the first major governmental backing in the world for the emerging carbon capture technology. ...But critics of the strategy are plentiful as well. Benson’s Stanford colleague Mark Jacobson, an atmospheric scientist, calls the program “a boondoggle” and “a complete waste of money.” He argues that because DAC requires so much energy to capture CO2, purify it, and pump it underground for permanent storage, it is one of the most expensive and inefficient ways to sequester carbon. A better climate strategy, Jacobson says, would be to simply spend the money on building out renewable energy faster, so that coal and natural gas electricity plants can be retired more quickly. But DAC proponents counter that even though the world is spending more than $1 trillion a year on clean energy technologies, that won’t be enough for countries to meet their carbon reduction goals....
