Backs Boston Metal to decarbonize steel using molten oxide electrolysis
[RECORD.TXT] · cat --full
Breakthrough Energy Ventures led a $120 million Series C in Boston Metal, an MIT spin-out using electrolysis to produce carbon-free steel. Traditional blast furnace steelmaking accounts for roughly 8% of global CO₂ emissions. Boston Metal's process replaces coal with clean electricity, enabling zero-emission steel production. Gates has repeatedly named green steel as one of the hardest and most important decarbonization challenges.

Gates-Backed Commonwealth Fusion Installs Its First Magnet, Racing Toward 2026 'First Plasma'
Commonwealth Fusion Systems — backed by Bill Gates's Breakthrough Energy — hit a major hardware milestone heading into 2026, installing the first of 18 powerful high-temperature superconducting magnets in its SPARC tokamak near Boston. CFS is racing to achieve 'first plasma' in 2026 and net energy gain in 2027, aiming to prove that commercial fusion power is possible. It is among several fusion ventures Gates has funded in his long search for an 'energy miracle' to fight climate change.

TerraPower Begins Building America's First Utility-Scale Advanced Reactor in Wyoming
On April 23, 2026, Bill Gates's nuclear company TerraPower formally began nuclear construction of its first Natrium reactor in Kemmerer, Wyoming — billed as the first utility-scale advanced nuclear power plant built in the United States. The milestone followed the Nuclear Regulatory Commission's approval of the construction permit, and came after earlier work on non-nuclear facilities and a multi-year delay caused by the loss of Russian fuel supplies. The 345-megawatt sodium-cooled reactor, with molten-salt energy storage, is central to Gates's bet that next-generation nuclear can deliver clean, around-the-clock power.
