Rent-a-GPU outfit Lambda says its latest Nvidia GB300 NVL72 system is not only powered entirely by hydrogen fuel cells but doesn't consume a single ounce of water.

In fact, the fuel cell used to convert the explosive gas into electrons actually generates water as a byproduct, which ECL, the bit barn operator housing the cluster, says is recycled for facility cooling.

The off-grid datacenter, announced back in 2023, is located at ECL's Mountain View (MV1) campus and powered entirely by hydrogen fuel cells that, much like those found on spacecraft, combine hydrogen with oxygen from the atmosphere, generating power in the process.

In total, ECL claims its facility can support up to a megawatt of capacity. While that might sound like a lot of power, it's only enough for a handful of racks,
