GeoPura plans to deploy 2500 hydrogen power units (HPUs) to support off-grid EV charging infrastructure in areas facing grid capacity, access and planning challenges. Currently, 80 HPUs are in operation, with rapid expansion anticipated over the next five years.
The HPUs operate like diesel generators but use zero-emission green hydrogen fuel cell technology, producing only water as a byproduct. Renewable energy sources like wind and solar generate the hydrogen fuel. Public sector fleets, such as the Ministry of Defence (MoD), and companies like Balfour Beatty are already using HPUs for EV charging and site power. Cairn Lodge Services on the M74 in Lanarkshire has also adopted HPUs for EV chargers.
Each HPU delivers 250kVA of three-phase, 400V power with an integrated 216kWh battery system. Multiple units can be combined to scale as needed.
Matt Barney, chief hydrogen business officer at GeoPura, said the HPUs initially supported EV infrastructure, but have since expanded to construction, film production and outdoor events.
The MoD is trialling HPUs at five locations, including RAF Leeming and HMS Excellent Portsmouth, allowing EV charging on-site where grid power is insufficient. Barney highlighted that HPU-powered charge points cost around 70p/kWh, similar to rapid chargers on public networks.
GeoPura produces its own green hydrogen in partnership with Siemens Energy, and it plans to expand distribution to reduce delivery miles. With no moving parts, HPUs require minimal maintenance while offering reliable and sustainable power. Barney emphasised the role HPUs can play in scaling EV-charging infrastructure without delays, ensuring fleet managers can meet net-zero goals effectively.
