"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."
"These dense, rack-scale systems announced back at GTC this spring feature 72 of Nvidia's hottest Blackwell Ultra accelerators. In total, the system boasts roughly 20TB of HBM3e memory and an exaFLOP of dense FP4 performance. The consequence of such a dense system is power consumption. While a typical 4-node DGX deployment might have required 40 to 50 kilowatts per rack of power and cooling during the Hopper generation, just one of the Supermicro-built GB300 NVL72 systems is rated for 142 kilowatts of capacity."
Lambda deployed an Nvidia GB300 NVL72 system housed at ECL's off-grid Mountain View (MV1) campus powered entirely by hydrogen fuel cells that generate electricity by combining hydrogen with atmospheric oxygen. The fuel cells produce water as a byproduct, which ECL recycles for facility cooling. The GB300 NVL72 packs 72 Blackwell Ultra accelerators, roughly 20TB of HBM3e memory, and an exaFLOP of dense FP4 performance, resulting in very high power draw. Each GB300 NVL72 is rated at 142 kilowatts; an eight-system Superpod exceeds one megawatt. Hydrogen's environmental benefit depends on how the hydrogen is produced.
