Hydrogen Power for Construction
Zero-Emission Power for a Cleaner, Safer Construction Industry
The construction industry faces mounting pressure to reduce emissions, improve air quality, and enhance site safety, yet traditional diesel and HVO generators continue to dominate, releasing CO₂, NOx, and particulate matter into the environment. With grid limitations slowing down the adoption of electrified machinery and sustainability targets tightening across the sector, there is an urgent need for clean, scalable power solutions that support on-site operations, heavy equipment charging, and site electrification – without compromising performance.
“The GeoPura units we have been using at our sites have been an excellent and reliable source of zero-emissions power from the outset.” – Alan Silverster, KFB Carbon Manager

Introducing the GeoPura HPU™ for Construction
GeoPura’s Hydrogen Power Unit™ is transforming the industry by bringing renewable energy in construction to the forefront of site operations. Our HPUs™ provide a clean, reliable alternative to traditional construction site generators, replacing noisy diesel engines with zero-emission technology. Whether supplementing a limited grid or powering an entirely off-grid project, GeoPura ensures that your site offices, tower cranes, and EV fleets run on 100% sustainable power.
GeoPura has worked with leading construction firms, including Balfour Beatty, BAM, and EKFB, to deploy zero-emission hydrogen power for site offices, welfare units, crane operations, and EV charging, replacing diesel across critical infrastructure projects like HS2 and National Highways sites.

Power Performance & Environmental Impact: HPU™ vs. Diesel
| Feature | Standard 250kVA Diesel Generator | GeoPura HPU™ (250kW) | The "Win" for Construction |
| CO2 Emissions | ~17.5 Tonnes per month* | 0.0 Tonnes | Total Scope 1 decarbonisation. |
| Tailpipe Pollutants | High NOx and Particulate Matter | Zero (Water vapour only) | Ideal for Low Emission Zones (LEZ). |
| Noise Level (at 7m) | ~70 – 78 dB (Constant drone) | <45 dB (Near silent) | Easier Section 61 compliance/24hr work. |
| Fuel Security | Risk of diesel theft/spills | Hydrogen (Secure/Non-toxic) | No ground contamination risk. |
| Waste Heat | Lost to atmosphere | Recyclable | Can be diverted for site drying/heating. |
Note on Carbon Savings: > Estimated based on a 250kVA generator running at 75% load, 10 hours a day, 22 days a month. Actual savings will vary based on site duty cycles, but the HPU™ consistently delivers a 100% reduction in local emissions.
Case Study: EKFB
In collaboration with EKFB (a joint venture of Eiffage, Kier, Ferrovial, and BAM Nutall) and HS2, GeoPura successfully deployed its Hydrogen Power Units™ to decarbonise major infrastructure construction.
Primarily utilised at the Thame Valley Viaduct and rural footpath sites in Aylesbury, these units replaced traditional diesel generators to provide 100% renewable, off-grid electricity.
The deployment proved the reliability of green hydrogen in challenging, remote environments, ultimately saving over 189 tonnes of CO2 and significantly improving local air quality by eliminating NOx and particulate emissions.
This partnership serves as a landmark case study for the "diesel-free" construction movement, demonstrating that zero-emission technology can meet the high-capacity power demands of the UK’s most significant engineering projects.
Workers on construction sites are exposed to air pollution levels up to 15 times higher than urban background levels, largely due to diesel emissions.
