Co-founded TerraPower — a next-generation nuclear energy company
Gates co-founded TerraPower, a nuclear energy startup developing a Traveling Wave Reactor designed to run on depleted uranium waste rather than enriched uranium. The design addresses two of conventional nuclear energy's biggest problems: fuel cost and radioactive waste. Gates has described advanced nuclear power as one of the few technologies that can provide cheap, always-on, zero-carbon electricity at the scale the world needs to address climate change.

Breakthrough Energy Ventures Invests in Savor — Butter Made Directly from Carbon
Breakthrough Energy Ventures backed Savor, a startup that produces butter using carbon dioxide and hydrogen — derived from atmospheric carbon and water — without any conventional agriculture, animals, or farmland. Savor's thermochemical process generates saturated fat with an identical molecular profile to dairy butter while using an estimated 99.9 percent less water and zero agricultural land. The product launched at Michelin-starred restaurants in 2025, with supermarket availability targeted for 2027, as part of Gates's broader bet on food-system decarbonisation.

Breakthrough Energy Catalyst Invests $40 Million in Deep Sky Carbon Removal
Breakthrough Energy Catalyst — Gates's industrial decarbonisation investment vehicle — committed $40 million to Deep Sky, a Quebec-based company developing commercial direct air capture facilities across Canada. The investment marked Catalyst's first in the DAC sector. Deep Sky's Alpha facility in Alberta is designed as a testing ground for multiple next-generation carbon removal technologies, with the goal of proving the cost trajectory needed to make DAC viable at planetary scale.
