While the world's tech giants grapple with AI data centers, Breakthrough Energy Ventures is setting its sights on the real energy crunch looming on the horizon. Eric Toone, managing partner at Breakthrough Energy Ventures, argues that data centers are the canary in the coal mine, hinting at a surge in electricity demand that will dwarf today’s struggles.

Their response: a diverse cohort of 21 startups, from proton-boron fusion to semiconductor efficiency, targeting everything from agriculture to hydrogen transport. StarWarden and Borealis Fusion are pushing the boundaries of nuclear fusion, while K1 Semiconductor is aiming to slash costs in key materials. These ventures reflect a dual approach: decarbonization and adaptation to a warming world.

Yet, amidst these ambitious bets, a sobering truth emerges. Ashley Grosh, who previously led the Breakthrough Energy Fellows program, has departed for greener pastures, leaving a gap filled by senior director Benjamin Gaddy. The program continues to focus on high-risk, high-reward investments, much like a startup itself.

The stakes are high, with hydrogen emerging as a key player. AmHyTech and Ammovolt Energy are developing ammonia solutions to transport hydrogen, a potential game-changer. But the real challenge lies in the infrastructure. Toone notes that there's essentially zero capacity to move hydrogen around, a glaring gap that needs to be filled if these startups are to succeed.
