The clean energy transition doesn’t just need a ton of solar panels, electric vehicles, and batteries. It needs aluminum — a key component to all of those technologies and many more.
In the next 25 years, global aluminum demand is set to surge as much as 80% as we deploy clean energy and build out the grid. But if we keep making aluminum the way we have for decades, the emissions-heavy process will outweigh a lot of the clean benefits it’ll unlock.
A massive new aluminum smelter wants to set a new status quo, Canary Media reports in the first of a two-part series. Using $500 million from the U.S. Energy Department, the Century Aluminum plant aims to run on carbon-free energy and implement efficient designs to curb its emissions as much as 75% compared to traditional smelters. Procuring all that clean power won’t be easy, though, and the part of Kentucky where it’s likely to be built is also scaling up solar and transmission development to meet the demand.
Recycling can meanwhile reduce the need for new aluminum in the first place, Canary Media continues. As much as 80% of aluminum produced in the U.S. is recycled, and the industry relies on trash pickers, scrappers, and everyday Pepsi drinkers to gather up recyclable material. But because secondary aluminum still demands some virgin material, experts say cleaning up smelters should be the industry’s top priority.
Also this week in essential clean energy materials: There’s a debate raging over the merger of two major steel companies, Grist reports. Japanese steelmaker Nippon Steel is looking to acquire U.S. Steel in a move some environmentalists say could slow both companies’ climate progress. The carbon-intensive industry has been notoriously slow to clean up its processes even with federal funding available, and advocates want to make sure the government keeps that in mind as it approves the consolidation.
