TL;DR

Imagine a power plant whose fuel comes out of ordinary water, that leaves behind only helium and that sells electricity for under 2 euro cents a kilowatt-hour. That is what a Swedish start-up, 2D Fusion AB, announced on Nov. 5: it says it is now selling fusion reactor parts and control systems, with first deliveries in the third quarter of 2029 and a first 1-gigawatt plant, enough for about 750,000 homes, running by 2032. It is a company claim, made in a press release with no test data attached, and it aims at the hardest version of fusion there is: burning deuterium, a heavy form of hydrogen, on its own. If even part of it holds up, the race to clean, nearly bottomless power just gained a very bold entrant. To see our odds on whether those first parts ship on time, and the timeline of breakthroughs fusion still needs, subscribe.
