At the start of 2023, Yuval Bachar told us about his latest project - to build off-grid, hydrogen-powered data centers. As 2023 came to an end, he was back to tell us he'd done it.

He's got 1MW of capacity fed by hydrogen in Mountain View California, and he's telling potential customers he can build the same thing anywhere you can get hydrogen shipped by pipe or tanker. 

He's keen on the benefits. No long waits for power distribution, no struggles getting permits for diesel. And the building is quick and cheap too. He can make them with a 3D concrete printer - which incidentally is environmentally better than tilt-up building, he says. 

He picked up the Environmental Impact prize at this year's DCD Awards, and joined the podcast to give us some more details on what he has done.... and what's coming next
