Equinix has deployed a hydrogen power system at its DB3 data centre in Dublin, marking its first live trial of the technology across its global estate. Delivered in partnership with ESB and GeoPura, the 12-week pilot seeks to address ongoing grid capacity constraints in the Dublin region, where energy availability continues to shape data centre development.

Two hydrogen-powered generators, each housed in container-sized units, are operating onsite to support cooling infrastructure. Together, they provide up to half a megawatt of continuous power, with the ability to respond dynamically to grid conditions through uninterruptible power supply( UPS) integration. The trial has already contributed to reducing power use effectiveness( PUE) at the facility to below 1.3.

“ This is a landmark research project that could be part of the solution to Ireland’ s grid constraints and the
