Mobile Hydrogen Power: Whitepaper
Electricity demand is rising, grid connections are delayed, and diesel is facing growing pressure from emissions, noise, health concerns, and tighter regulations.
This whitepaper explores how GeoPura’s Hydrogen Power Unit™, manufactured by Siemens Energy, replaces diesel generators in temporary, off-grid, backup, and grid-constrained applications across construction, utilities, EV charging, data centres, events, and critical infrastructure.
GeoPura’s Hydrogen Power Units replace diesel generators with zero-emission electricity – for construction sites, events, EV charging, data centres, and critical infrastructure. No exhaust. No noise. No compromise on reliability.
- Manufactured by Siemens Energy
- UK-based production
- 24/7 remote monitoring
Diesel is no longer good enough
Grid connections are delayed. Regulations are tightening. ESG targets are non-negotiable. And diesel generators carry real costs to air quality, worker health, and your reputation.
2012
WHO classified diesel exhaust a lung cancer carcinogen
2030
London generators must meet Stage V emissions standard
10M+
Tonnes of CO₂ displaced over HPU fleet lifetime
From Low Emission Zones to fossil-free construction site mandates, the regulatory direction is clear. Companies relying on diesel face compliance risk, permit costs, and reputational damage, especially on public-facing projects.
Hydrogen Power Unit™: proven, deployable, clean
GeoPura’s HPUs are containerised hydrogen-battery hybrid power systems that deliver zero exhaust emissions at the point of use. Unlike batteries, they don’t need recharging. Unlike HVO generators, they produce no local emissions and face no palm oil supply constraints.
Procured as energy-as-a-service, including hydrogen supply, delivery, monitoring, and support – HPUs give you clean, reliable power without building any in-house hydrogen capability.

Where HPUs are working today
- Construction & infrastructure – Off-grid site power for HS2, Balfour Beatty, National Highways, and National Grid projects.
- EV charging – Enabling fleet electrification where grid capacity lags, including Ministry of Defence and Westmorland Services deployments.
- Events & broadcast – Clean power for the Isle of Wight Festival, Touch Rugby World Cup, Extreme H championship, and BBC live coverage.
- Data centres – Co-located, self-sustaining power reducing exposure to grid congestion and planning delays.
- Critical infrastructure & backup – Instant backup power for the Munich Security Conference 2026, protecting live broadcast and sensitive operations.
