Supporting the move to electric vehicles
In a pan-Defence collaboration, trials of hydrogen fuelled charging facilities to power the electric vehicle fleet have concluded.

This marks a significant step forward in the use of sustainable energy sources in Defence.
Generating enough electricity to power roughly 120,000 miles of travel, the trial provided learning on the use of hydrogen as a source of fuel in Defence’s future energy mix.
Hydrogen provides an opportunity to influence operations at home and overseas, as well as providing resilience and mobility in off-grid and compromised locations. Following the trials successful delivery, new initiatives focused on hydrogen as an energy system for Defence, are planned.
Starting in August 2023, the trial 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).
On the trial, 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.
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.
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.
Hydrogen is just one of the ways Defence might be able to manage electric vehicles in the 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.
