The country’s first new aluminum smelter in 45 years could cut production emissions by 75%.Century Aluminum Co. hopes half a billion dollars in federal funding will help it revive a dying industry while making it less polluting. 3 May 2024Aluminum is a crucial raw ingredient in the fight against climate change. But to ensure the transition off fossil fuels is a clean one, the industry needs a serious makeover. A new federally-funded “green smelter” could help make that happen. Making this remarkably versatile metal requires a huge — and near-constant — supply of electricity. Much of it is generated by burning fossil fuels, which is one reason aluminum manufacturers are responsible for about 1.1 billion tons of carbon dioxide emissions a year. That’s more than twice the amount all of Australia spews annually.
Cleaning things up poses a huge challenge, one the Department of Energy, or DOE, wants to help solve. In March, the agency announced $6 billion in funding for “industrial demonstration” projects that showcase promising strategies for reducing the climate impact of heavy industry. The need is particularly acute, because heavy industrial processes like aluminum production generate nearly one-third of the country’s greenhouse gas emissions. That could boost a sector on life support. Although the United States once led the world in producing the lightweight and durable metal, most of the country’s aluminum smelters have shuttered since the 1980s due to rising energy costs, falling prices, and a broader trend of American firms sending manufacturing overseas. And that’s to say nothing of the aluminum required for EVs, power transmission lines, and countless other applications, from cookware to cell phones. Even recycling the stuff requires virgin material, which is mixed into all those melted cans and car parts and other scrap to produce quality metal.....read on https://grist.org/solutions/the-nations-first-new-aluminum-smelter-in-45-years-could-cut-production-emissions-by-75/?utm_medium=email&utm_source=newsletter&utm_campaign=daily
