Overview
- Lambda, ECL and Supermicro say the first production-grade NVIDIA GB300 NVL72 racks are now running at ECL’s Mountain View MV1 campus powered entirely by hydrogen fuel cells with no external water draw.
- The Supermicro-built NVL72 systems house 72 GPUs per rack and are reported to be rated at about 142 kW each, though Lambda has not disclosed how many racks are installed.
- ECL says MV1 can support up to roughly 1 MW, suggesting the deployment is smaller than a fully loaded GB300 Superpod, which would exceed that power level.
- Operators report that water produced by the fuel cells is captured, purified and reused in a closed-loop liquid cooling system, with efficiency, water-recycling performance and emissions claims pending independent validation.
- The companies frame MV1 as a proof of concept for scaling to ECL’s planned TerraSite‑TX1 near Houston, while the availability of sustainably produced hydrogen and supporting infrastructure remains uncertain.
