Invests in Form Energy's iron-air battery for 100-hour grid storage
[RECORD.TXT] · cat --full
Breakthrough Energy Ventures co-led a $200 million Series D in Form Energy, which is developing an iron-air battery capable of discharging over 100 hours — far longer than lithium-ion. The technology uses cheap, abundant iron and atmospheric oxygen, dramatically reducing material costs compared to other long-duration storage approaches. Long-duration storage is considered a prerequisite for a grid powered predominantly by wind and solar.

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.
