Integrating hydrogen into data centre energy systems Beyond backup, the trial explores how hydrogen can be integrated into wider data centre energy strategies. The system’ s ability to operate alongside battery storage and UPS infrastructure allows for real-time responsiveness, supporting both resilience and peak shaving.
“ As demand for digital infrastructure continues to grow, operators are facing increasing pressure to secure reliable power, reduce emissions and minimise the impact on local communities,” explains Andrew Cunningham, CEO of GeoPura.
“ This trial shows how hydrogen can help address those challenges today. By combining hydrogen fuel cell technology with battery systems and uninterruptible power capabilities, we’ re delivering reliable zero direct onsite-emission power that can respond instantly when required.
“ Working alongside Equinix and ESB, this project is demonstrating that hydrogen can support both backup and prime power applications in a live data centre environment, showing how hydrogen can strengthen energy resilience, reduce reliance on fossil fuels and support the continued growth of critical digital infrastructure.”
The trial also highlights potential secondary efficiencies. Waste heat generated by the fuel cells could support district heating schemes, while water byproducts may be reused within cooling systems, reducing reliance on mains supply.
