GeoPura™ HPU

When the grid can’t deliver, the GeoPura HPU uses fuel cell technology to supply clean, large-scale power when and where it’s needed and the only by-product is pure water.

Leading the way in hydrogen power capabilities, the GeoPura unit has provided energy for festivals, displaced diesel generators in construction and delivered reliable power without any damaging emissions.

Our HPU is fuelled with green hydrogen which is a clean fuel. Producing green hydrogen, with renewable energy, does not harm the environment; unlike diesel and even bio replacements like HVOs, which still produce harmful emissions and can have a devastating impact on natural habitats.

  • Fully redundant, uninterruptable power system rated for full load
  • Direct support for connecting grid supply or renewable generation
  • Connected renewables continue generating during external grid outages/constraints
  • Can be supplied with EV charging posts to create an off-grid charging facility
  • Can be used in a CHP (combined heat and power) mode to provide heating and hot water at no added cost
Combined heat and power

The HPU can be configured to supply 50kW of hot water (60oC) via a heat exchanger.

EV fast charging

The HPU can be supplied with charging posts to create temporary or permanent grid-independent EV charging facilities.

How it works 

The GeoPura Hydrogen Power Unit is a clean, efficient, and reliable solution that enables businesses to eliminate diesel generators and transform their energy use. By providing zero-emission energy, the HPU helps companies reduce their carbon footprint and meet their decarbonisation goals. With advanced power controls and onboard batteries, the HPU offers a fully redundant, critically backed supply capable of peak shaving and grid augmentation.  
Moreover, the HPU is scalable, cost-effective, and sustainable, making it an attractive solution for businesses looking to transition to clean energy. At GeoPura, we are committed to helping businesses reach their net-zero ambitions sooner by providing zero-emission energy wherever it’s needed.

Our Service

Where can I use a HPU?

The HPU is ideal for a wide range of applications, helping to decarbonise industry sectors on the journey to Net Zero. Already proven by multiple high-profile deployments, including recently powering the live TV broadcast of the DP World Golf tour, providing EV charging for the MOD and powering the shutdown of a Uniper power station in the UK, companies such as the BBC, Balfour Beatty, National Grid and many more are already reducing their carbon footprint and contributing to a more sustainable energy system today.

Power Requirements

How much power do you need?

GeoPura’s Energy as a Service model is ideal for developing sites and long-term projects. Our HPU is a scalable technology offering power outputs from 250kW up to 1MW.

This enables the setup to be customised to site load and adapt to power requirements, creating a more efficient, reliable energy solution.

Providing critically backed, reliable and consistent electricity to supplement grid connections and standalone power. The HPU is also ideal as a short-term solution for temporary power on sites with future DNO connection plans.

Utilising a HPU provides the opportunity to transfer more applications over to clean energy as your project site grows and develops long-term.

You can also benefit from additional services such as a Combined Heat and Power system and EV Charging facilities.

How does the HPU compare to a traditional generator?

Diesel vs Hydrogen

Diesel generators were designed without considering environmental concerns, resulting in the release of harmful pollutants such as carbon dioxide, nitrogen oxide, and particulate matter.

Prolonged usage of diesel generators leads to local air quality issues and contributes to global climate change.

Increased levels of toxins and noise from diesel generators can have negative impacts on the health of individuals living and working near the site.

Governments are implementing low-emission zones and net-zero targets, penalizing companies that continue to use fossil fuels.

The GeoPura HPU is a reliable, consistent, and renewable alternative to diesel generators, successfully deployed in various industries since 2019. Ideal for short term hire, off grid and environmentally sensitive locations.

The HPU offers significantly lower noise levels and zero emissions, providing a game-changing solution for power generation without negative impacts on air quality and health.

The benefits

Why choose us?

bar chart icon

More efficient

HPUs convert hydrogen fuel directly into electrical energy. Unlike traditional combustion engines that convert fuel into heat and then mechanical work.

tree icon

No harmful emissions

HPUs emit just water and a little heat. Internal combustion engines emit CO2 and pollutants such as NOx and particles.

turning cog icon


HPUs have no moving parts and require less maintenance. Integrated 216kWh battery storage provides hours of back-up should a hydrogen supply be interrupted at any stage

About GeoPura

GeoPura was founded to help source enough clean energy to electrify our global economy and navigate the logistical issues of getting this energy to where it is needed.

The GeoPura solution uses renewable energy, normally solar PV or wind, to create hydrogen and hydrogen based zero emission fuels. This fuel is then transported to locations where a local generator converts it to electrical power. From start to finish the process is clean and carbon free – the only by-product is pure water.
