It Just Signed a Contract to Replace Them With Transportable Hydrogen Microgrids That Charge Electric Cars Anywhere, Off the Grid"},"content":{"rendered":"

Military bases needing reliable power is hardly a new concern. Diesel generators have been the default backstop on RAF runways and Army garrisons for decades, humming away whenever the grid hiccups or a deployment sets up shop somewhere with no grid at all. But the Royal Air Force just signed a contract that tries to ditch the diesel entirely, and it’s leaning on hydrogen to do it.<\/p>\n

Nottingham-based GeoPura has been named prime contractor on a Ministry of Defence programme to roll out six self-powering EV charging hubs across RAF sites, according to Hydrogen Central<\/a>. Each hub is a transportable microgrid that stitches together solar panels, hydrogen-fuelled power units and battery storage, with the idea that it can run an EV charging<\/strong><\/a> operation without ever touching the national grid or burning a drop of fossil fuel. The first two units are due to enter service this summer for what the MOD calls Initial Operating Capability, with all six in place by the end of October 2026 for Full Operating Capability. GeoPura then sticks around on operations and support for three years after that.<\/p>\n

What’s actually being deployed at the RAF sites<\/h2>\n

The hardware is built around GeoPura’s Hydrogen Power Units, which are essentially fuel-cell generators on skids. As TwinFM<\/a> describes the HPU, it behaves like a self-charging battery, with a fuel cell turning hydrogen into electricity and emitting only water and heat at the point of use. On the RAF hubs, those units sit alongside solar generation and battery storage, and the chargers themselves bolt onto the front end.<\/p>\n

The design priority here is “solar-led” with hydrogen<\/strong><\/a> on standby. When the sun is doing its job, the solar array carries the load and tops up the batteries. When it isn’t (which, this being the UK, is most of the time), the HPUs kick in to keep cars charging and the site running. Group Captain Maurice Dixon of the RAF told Hydrogen Central that the six units will support the service’s growing electric vehicle fleet and provide “flexible surge power capacity for various operational needs, including grid reinforcement and deployment scenarios.”<\/p>\n

That last bit is the interesting part. These aren’t just charge points for the base motor pool. They’re modular and transportable, so the RAF can theoretically pick one up and drop it on a forward site, an exercise location or anywhere the grid is either unreliable or non-existent.<\/p>\n

Why the MOD is buying hydrogen instead of more diesel<\/h2>\n

Energy security is genuinely on the table in defence procurement right now, and the grid-independence pitch is doing a lot of work in this contract. A microgrid that doesn’t need a fuel convoy or a substation is harder to knock offline, which matters when the alternative is parking a diesel genset somewhere and praying nobody cuts the supply chain.<\/p>\n

GeoPura already has form here. The company ran charging hubs for the MOD’s Future Energy Trials back in 2024, with deployments spanning RAF, Royal Navy and Army locations to prove off-grid zero-emission setups could actually hold up under operational use. The new contract is essentially the production order that follows those trials. GeoPura CEO Andrew Cunningham framed it in the announcement as a step toward “strengthening the RAF’s resilience while reducing reliance on fixed infrastructure and fossil fuels.”<\/p>\n

There’s also the net-zero accounting angle. UK Defence has its own carbon targets, and swapping diesel gensets for solar-plus-hydrogen knocks a noticeable chunk off the emissions ledger without forcing the RAF to wait for a grid connection that might take years to upgrade.<\/p>\n

GeoPura is having a busy 2026<\/h2>\n

The RAF deal lands in the middle of a run of contracts that has put GeoPura’s name on quite a lot of UK infrastructure this year. In February the company was named hydrogen supplier for National Highways’ Lower Thames Crossing project, per Quantum Commodity Intelligence<\/a>. In March, GeoPura and Forth Ports signed off on a green hydrogen production project planned for the Port of Tilbury site. In April, the firm announced a trade partner agreement with Sunbelt Rentals UK & Ireland to push HPUs and green hydrogen supply through Sunbelt’s national hire network, putting hydrogen power into the temporary-rental market that has historically run on diesel.<\/p>\n

And earlier this month, Quantum reported a National Highways construction compound being powered by hydrogen for what was described as a company first. The cumulative picture is a hydrogen vendor that’s quietly stitching together a portfolio across defence, public infrastructure and the rental market at the same time, which is more or less the playbook for getting a hydrogen supply chain to scale before the demand side catches up.<\/p>\n

The economics of a hub like this<\/h2>\n

Solar-plus-battery-plus-hydrogen is not the cheapest way to charge an EV. Grid power, where it exists and where it works, is still going to win on a straight pence-per-kWh basis. The MOD isn’t buying these hubs because they’re cheap, it’s buying them because they’re independent. That changes the cost calculation entirely. If the alternative is trenching new grid connections across a Cotswold runway, or running diesel generators with all the fuel logistics that implies, a self-contained microgrid starts to look reasonable.<\/p>\n

The HPU concept itself sidesteps the chicken-and-egg problem that has haunted hydrogen transport for years. You don’t need a hydrogen filling station network to use one of these, because the hydrogen gets trucked in as fuel for the unit, not for the vehicles. The cars plugging in are bog-standard battery EVs. The hydrogen is just doing the job a diesel generator would otherwise do, with water as the tailpipe output instead of NOx and particulates.<\/p>\n

What the contract doesn’t say<\/h2>\n

The announcement doesn’t put a value on the deal, doesn’t specify which six RAF sites are getting the hubs, and doesn’t break out how much hydrogen GeoPura expects to consume across the three-year operations and support window. It also doesn’t lay out what happens at the end of that three-year period, whether the MOD extends, takes the hubs in-house, or expands the rollout to more bases.<\/p>\n

What the RAF and GeoPura have confirmed is that the six-site deployment is being pitched as a scalable template. If it works on the first half-dozen bases, the door is open for the same package to land at other RAF sites and across the wider MOD estate. Alongside the contract, GeoPura signed the Armed Forces Covenant, which is the standard commitment UK companies make to support serving personnel, veterans and reservists.<\/p>\n

For now, the deliverable is concrete enough. Two hubs live this summer, all six by late October, and a three-year support tail. If GeoPura hits those dates, the RAF gets a working answer to whether you can run a defence-grade EV charging operation without a grid connection or a diesel tank. If it slips, the diesel gensets aren’t going anywhere.<\/p>\n","protected":false},"excerpt":{"rendered":"
