Bill Gates’ Breakthrough Energy Selects 21 Startups for Future Energy Innovation

Breakthrough Energy, the climate technology organisation founded with support from Bill Gates, has announced its latest Breakthrough Energy Fellows cohort featuring 21 startups developing technologies across energy, climate, and industrial sectors.

The sixth cohort includes companies working on nuclear fusion, semiconductor efficiency, hydrogen, agricultural technology, robotics, and climate adaptation. Breakthrough Energy said the program supports early-stage founders developing technologies that could contribute to future energy systems.

New Technologies for Rising Energy Demand

Breakthrough Energy Ventures managing partner Eric Toone said the growing demand for electricity from AI data centres is part of a broader increase expected as more industries transition toward electrification.

The organisation is supporting startups that aim to address challenges across the energy sector, including power generation, efficiency, storage, and infrastructure.

Fusion and Advanced Computing Technologies

Borealis Fusion is developing a fusion approach based on proton-boron fuel. This technology could offer benefits but remains technically challenging because fusion reactions require extreme conditions.

StarWarden is developing heat-management technology for future fusion reactors, addressing one of the engineering challenges associated with advanced nuclear systems.

Several fellows are focused on improving semiconductor and data centre efficiency. Bedrock Semiconductor and K1 Semiconductor are among the companies developing technologies to improve electronic systems and reduce energy costs.

Hydrogen, Agriculture and Climate Solutions

Breakthrough Energy is also supporting companies working on hydrogen transportation, agriculture, and critical materials. AmHyTech is developing technology for hydrogen and ammonia systems that could help address challenges in hydrogen distribution.

The cohort also includes companies exploring areas such as molecular sensing for crop disease detection and robotics for resource extraction. Mithril Minerals is among the startups working on critical mineral technologies.

Breakthrough Energy’s latest group reflects a mix of technologies focused on reducing emissions, improving energy efficiency, and helping societies adapt to climate challenges.
