Hydrogen-fuelled charging facilities trialled at RAF sites

Trials of hydrogen fuelled charging facilities to power an electric vehicle defence fleet have concluded.

The trial, which started in August 2023, was initially planned for three sites (RAF Leeming, Devonport Naval Base and Merville Barracks in Colchester). It was later extended to include two more (HMS Excellent Portsmouth and RAF Northolt).  

Following the trial's successful delivery, new initiatives focused on hydrogen as an energy system for Defence, are planned.

The trial used Hydrogen Power Units (HPU) to convert hydrogen into electricity, which is then harnessed to charge electric vehicles via fast-charging posts. The HPUs provided a reliable and environmentally friendly source of power, ensuring seamless rapid charging with zero harmful emissions. They also bypass the constraints of grid capacity, allowing MOD to provide power even in areas where grid upgrades are delayed or not feasible.  

This work was a joint endeavour between Defence Support within Strategic Command, the Defence Infrastructure Organisation (DIO) and Front Line Commands (FLC), delivered in partnership with industry experts, GeoPura.  

Assistant Chief of Defence Staff (Support Operations), Air Vice-Marshal Rich Pratley said: "In embracing innovative solutions like hydrogen power, the Ministry of Defence has reaffirmed its commitment to sustainability and as the trial has proved, to improving operational efficiency.

"This trial has demonstrated the potential of hydrogen as a key enabler of our transition to zero-emissions energy, while also addressing the current challenges posed by our expanding electric vehicle fleet."

GeoPura’s Chief Hydrogen Business Officer, Matt Barney, said: "GeoPura HPUs and supply of green hydrogen provide a seamless solution to these challenges. By harnessing the power of green hydrogen, our generators ensure rapid charging with zero harmful emissions, completely unrestricted by grid limitations. This not only facilitates the widespread adoption of EVs but also contributes to a cleaner and more sustainable future."

Defence Support are now expanding the trials across other Defence sites and are working with partners, such as DIO, to consider how Defence can use hydrogen in other ways.
