The UK Ministry of Defence (MOD) has successfully concluded trials of hydrogen-fuelled charging facilities to power its growing electric vehicle (EV) fleet.
This initiative marks a significant step in the military’s journey towards adopting cleaner energy sources and reducing its carbon footprint.
Powering the Future of Defence
The trials, which began in August 2023, initially encompassed three sites: RAF Leeming, Devonport Naval Base, and Merville Barracks in Colchester. Due to promising results, the project was expanded to include HMS Excellent Portsmouth and RAF Northolt.
Outcomes of the trial include:
- Generation of electricity equivalent to powering 120,000 miles of travel
- Insights into hydrogen’s potential as a future energy source for Defence
- Demonstration of off-grid charging capabilities for enhanced resilience
Air Vice-Marshal Rich Pratley, Assistant Chief of Defence Staff (Support Operations), highlighted the significance of the trials:
“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.”
How Hydrogen Power Units Work
The researchers in the trial converted hydrogen into electricity using Hydrogen Power Units (HPUs), and then used this electricity to charge EVs via fast-charging posts.
This system offers several advantages:
- Zero harmful emissions
- Reliable power source
- Bypasses grid capacity constraints
- Enables charging in areas with limited infrastructure
A Collaborative Effort
This initiative was a joint endeavour involving:
- Defence Support within Strategic Command
- Defence Infrastructure Organisation (DIO)
- Front Line Commands (FLC)
- Industry partner GeoPura
Matt Barney, GeoPura’s Chief Hydrogen Business Officer, emphasized the potential of their technology:
“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.”
The Road to Net-Zero
The success of these trials has paved the way for further exploration of hydrogen as an energy system for Defence. As part of the UK government’s broader Net Zero goal by 2050, the military is taking significant steps towards electrification:
Year |
Milestone |
|---|---|
| 2027 | 100% of non-operational “white fleet” to be fully electric |
| 2030 | Deployment of hybrid electric drive (HED) equipped troops |
| 2035 | Migration to sustainable power sources for most applications |
| 2040 | RAF pledges to be net-zero |
While challenges remain, particularly for large platforms and combat vehicles, the MOD’s commitment to innovation and sustainability is clear. The successful hydrogen charging trials represent a crucial step towards a greener, more resilient future for UK Defence.
