Green energy through scaling up hydrogen fuel cells

Based in the United Kingdom, GeoPura provides clean, reliable hydrogen energy for various industries to replace diesel generators, supplement the electricity grid, reduce emissions and ensure uninterrupted power supply even in the most demanding environments.

By integrating green hydrogen production, hydrogen storage and hydrogen fuel cell technology, GeoPura is creating a resilient hydrogen ecosystem that delivers low-carbon energy where and when it is needed. HARTING's connectivity and cabling solutions are helping to scale up.

At the forefront of the energy transition, GeoPura, founded in 2019, is tackling one of the greatest challenges of all time: eliminating reliance on fossil fuels. Developing scalable solutions for clean energy is crucial for decarbonising our global economy. By using hydrogen fuel cell technology, GeoPura offers energy storage solutions that enable the time-delayed, demand-driven use of renewable energies such as wind or solar power.

GeoPura’s HPU2 (second generation Hydrogen Power Unit) delivers off-grid and supplementary power up to 500kW, (scalable up to 50MW) providing renewable energy whenever and wherever it’s needed. Fuelled by green hydrogen, a zero-emission fuel, HPU2 replaces diesel generators as a backup and serves as prime power for data centres, EV charging, construction, film production, events, and more. It ensures clean, reliable electricity with only water and heat as by-products.

The HPU2 offers efficient, robust, and safe power distribution, helping industries reduce their reliance on fossil fuels. Whether supporting grid resilience or powering remote locations, HPU2 delivers a future of sustainable, emissions-free electricity.

The hydrogen transition is well underway, but strong partnerships are needed to drive it forward. GeoPura's strategic partnership with Siemens Energy has been instrumental in accelerating global decarbonisation on the path to a greener world.

Since 2019, the Hydrogen Power Units (HPUs) have been mass-manufactured in the United Kingdom by Siemens Energy, ensuring high production quality, reliability and scalability.

A key challenge is scaling up this innovative solution to meet the growing global demand for clean energy. The partnership between GeoPura and HARTING has advanced manufacturing of the fuel cell generators in the UK. By working closely together, the companies have been able to accelerate the production of hydrogen power systems and use the available space as efficiently as possible. The result is outstanding.

The partnership between GeoPura and HARTING is a real success story based on a shared vision of the All Electric Society. Two companies that firmly believe in the energy transition are working closely together to decarbonise energy consumption in various industries.

Engineers from both companies discussed various options for accelerating the production of the HPUs. One of these proved particularly advantageous for scaling: the use of pre-assembled cable harnesses with rear mounting functionality.

Normally, cable harnesses and connector parts must be inserted from the inside of the control cabinet into a housing attached to the inside wall of the control cabinet. This can be quite a complex challenge. The rear mounting option for industrial connectors offers valuable time savings for equipment using the Han® industrial standard.

For installation, both ends of the cable harnesses can be rear-mounted from the inside of the switch cabinet into the bulkhead-mounted housing. HARTING supplies them as pre-assembled and tested cable assemblies. This allows the work to be divided up, further increasing efficiency and thus productivity.

Another key to succeess is the use of HARTING’s modular connector series Han-Modular®. GeoPura benefits from a high I/O density, enabled by HARTING’s RJ45 Domino module. Making use of the Domino modules allows for smaller and lighter connectors. The results are space savings of up to 50%, and maximum flexibility, scalable to the respective need.
