How it works

GeoPura is enabling the production, transport, and use of zero-emission fuels through innovative, commercially viable technology that decarbonises power generation and supports the transition to a cleaner global economy.

Zero Emission Fuels

From green hydrogen production using renewable electricity to hydrogen-powered generators delivering clean, reliable energy, we offer a complete solution for sustainable power.

How does a
Hydrogen Powered Generator work?

A Hydrogen Powered Generator, like our HPU, works like a self-charging battery system, powered by green hydrogen. Inside the unit, hydrogen is combined with oxygen from the air in a fuel cell, where a chemical reaction takes place, splitting hydrogen atoms into protons and electrons. The electrons flow through an external circuit, generating direct current (DC) electricity.

This DC power is then passed through inverters to create alternating current (AC), which is conditioned and stabilised to deliver 400V three-phase electricity. The system also includes advanced power controls and onboard battery storage to ensure a redundant, uninterruptible power supply capable of peak shaving, load balancing, and off-grid operation – all with zero harmful emissions.

Our HPU Units

Hydrogen Production

We generate green hydrogen from renewables using electrolysis, a process that uses clean electricity, typically from solar or wind power, to split water into hydrogen and oxygen. This creates a zero-emission alternative fuel that can be used to decarbonise power, transport, and industry.

Delivery & Refuelling

GeoPura offers a comprehensive fuel management system, delivering low-carbon hydrogen directly to site. With refuelling services for vehicles, plant, and HPUs, our infrastructure is designed for rapid deployment with no permanent installation required.

Plug and play solution

Our HPUs are set up and operated by GeoPura engineers, ensuring fast, safe installation and reliable performance. From site surveys to system integration, we manage every step of the process for a seamless customer experience.

Fully Monitored & Maintained

All systems are remotely monitored and maintained to maximise uptime, optimise performance, and ensure efficient energy use. Real-time diagnostics and predictive maintenance provide a hassle-free solution with built-in resilience.

Did you know?

Air pollution from burning fossil fuels, including diesel, causes an estimated 36,000 premature deaths per year in the UK.

Exposure to pollutants such as nitrogen oxides (NOx) and particulate matter (PM) contributes to respiratory diseases, heart conditions, and has been associated with an increased risk of dementia – (gov.uk)

How is green hydrogen produced?

Green hydrogen is produced through a process called electrolysis, which uses renewable electricity, typically from wind, solar, or hydro power, to split water (H₂O) into its basic elements: hydrogen (H₂) and oxygen (O₂). This process takes place inside a device called an electrolyser, which contains two electrodes submerged in water. When electricity is applied, it triggers a chemical reaction that separates the water molecules. The hydrogen is collected and stored as a clean, energy-dense fuel, while the oxygen is usually released into the atmosphere or captured for industrial use.

Because no fossil fuels are used and the electricity comes from renewable sources, green hydrogen is carbon-free from start to finish, unlike “grey” or “blue” hydrogen, which are produced using natural gas or other hydrocarbons.

Green hydrogen is then be stored, transported, and used in fuel cells, industrial processes, transport, and power generation, making it a vital tool for decarbonising hard-to-electrify sectors and creating energy security through long-term renewable storage.

Why Choose GeoPura for Clean Energy?

Scalable Solutions

From 50kW to 50MW solutions, GeoPura delivers scalable, efficient energy systems to suit any project. Already in mass production and backed by industry-leading engineers and global investors, we are powering everything from festivals to critical infrastructure.

Reliable Supply

HPUs have no moving parts, meaning less downtime and reduced maintenance. Even in the rare event of hydrogen supply interruption, the onboard self-charging battery continues to provide reliable backup power.

No Harmful Emissions

Our HPUs produce only water and a little heat, with no CO₂, NOx, or particulate emissions. Unlike diesel or HVO generators, they offer clean air benefits and protect both human health and the environment.
