Wrightbus Shows Hydrogen Bus Hype Turning Into An Electric Bus Business

A hydrogen bus fire in Crawley should not be turned into a simple hydrogen-cause story. That would be sloppy, and the investigation needs to run its course. But it is a useful hook for the real transit lesson: a small hydrogen fleet can create a large operational support problem, and that support problem gets harder to justify when the manufacturer’s commercial center of gravity is battery-electric buses.

Crawley and Gatwick were supposed to be one of Britain’s stronger hydrogen bus showcases. Go-Ahead, Metrobus, Wrightbus and Air Products had the right ingredients for the story: UK-built zero-emission buses, a liquid hydrogen refuelling station, airport-area routes, government-supported decarbonization, and a visible link to domestic manufacturing. The initial fleet involved 20 Wrightbus GB Kite Hydroliner buses for routes around Gatwick, Crawley and Horley, with hydrogen stored at the Metrobus Crawley depot in liquid form before being converted to gas for the buses. A further 34 buses were planned, taking the project well beyond a token demonstration and into the territory where fleet operations start to matter.

Then one of Metrobus’ hydrogen buses was destroyed in a fire in Crawley in early December 2025. No injuries were reported, which is the most important point. Metrobus described the withdrawal of its hydrogen single-deck buses as a precaution while the vehicles remained under investigation, and said it was using buses loaned from other operators to keep services running. Months later, the single-deck hydrogen buses are still reported as out of service. That is the part transit agencies should care about. The cause matters technically, but the operating consequence arrived immediately: a specialized zero-emission fleet became unavailable for an extended period and had to be backfilled.

The point is not to speculate about the cause of the fire or pretend that other vehicle technologies do not have faults. Diesel buses burn. Battery-electric buses have failures. Hydrogen fuel cell buses include batteries, power electronics, hydrogen storage, fuel cells and thermal-management systems, and any serious investigation has to distinguish among them. The point is operational. When a hydrogen fleet is small, specialized and dependent on a thin support ecosystem, one incident can turn into a much larger service, maintenance and confidence problem.

Wrightbus is the right company through which to examine this because it is a serious manufacturer with a visible recovery, real orders and a politically attractive industrial narrative. Hydrogen was central to the public story of the company’s post-administration rebirth. It gave the recovery a national-manufacturing hook, aligned neatly with the Bamford and JCB hydrogen push, and offered ministers an appealing zero-emission transport story with domestic jobs attached. The commercial denominator points decisively toward battery-electric buses.

That distinction matters because hydrogen transport stories often survive longer in policy narratives than they do in operating budgets. A few dozen hydrogen buses can look strategically important when they arrive with ministers, funding announcements, refuelling infrastructure and national-manufacturing language. Transit systems, however, are not run on launch-event logic. They are run on vehicle availability, route reliability, maintenance capacity, depot operations, fuel logistics, driver confidence and total cost.

Wrightbus’ recovery story was not casually adjacent to hydrogen. Hydrogen was part of the brand architecture of the rebound: visible, politically useful and wrapped into a broader UK industrial-policy narrative. The problem is that brand architecture and commercial gravity are not the same thing. Wrightbus’ large fleet orders and visible commercial momentum are much more strongly associated with battery-electric buses, especially Electroliners, than with hydrogen fleets multiplying across the country.

That does not mean Wrightbus will stop building hydrogen buses. It means the scalable business is battery-electric bus manufacturing. Hydrogen helped make the recovery story legible to politicians and the press. Electric buses are carrying the production volume, the repeat procurement and the operational learning curve.

Crawley makes the support-tail problem concrete. A hydrogen fleet is not just a set of buses. It needs fuel supply, refuelling infrastructure, trained maintenance, emergency procedures, spare parts, specialist diagnostics, safety procedures and operational workarounds when something is unavailable. If hydrogen is a minority drivetrain inside an operator’s fleet and a manufacturer’s order book, that support structure has to be justified against a much larger electric pathway that is getting more standardized with each procurement cycle.

Battery-electric buses have constraints of their own. Depot power, route scheduling, charger reliability, grid connections, winter performance and charging management all matter. Those are not trivial issues. The difference is that they are now mainstream transit-electrification problems, with a widening supplier base, repeated deployments and a clearer learning curve. Hydrogen adds another fuel system, another infrastructure chain, another maintenance regime and a thinner ecosystem.

The same pattern keeps appearing across transit procurement. Hydrogen looks strongest at announcement scale and weakest at fleet-turnover scale. It can make a compelling pilot, particularly where public funding absorbs much of the cost and industrial policy wants a hydrogen use case. It struggles when the comparison shifts to hundreds of buses, repeated orders, depot integration, service reliability and operating budgets that have to survive after the launch photos are gone.

For policy makers, the lesson is straightforward. Support domestic bus manufacturing, but follow the order book rather than the slogan. If the commercial scale is battery-electric, then the useful industrial policy is about reliable zero-emission bus production, workforce development, supply chains, charging infrastructure, depot upgrades and operator support. Hydrogen should clear the same filters as everything else: cost, reliability, infrastructure burden and repeat procurement.

For transit agencies, the denominator test is even more direct. A hydrogen bus procurement is a long operating commitment, not a technology-neutral press release. Agencies need to know who supplies the fuel, what it costs, how resilient the refuelling system is, how many trained technicians are available, what happens when the station is down, how warranties are handled and whether the supplier ecosystem is deep enough for a twenty-year fleet transition.

Wrightbus’ current trajectory makes the denominator visible. Hydrogen was central to how the rebound was presented: domestic manufacturing, zero-emission transport, industrial renewal and the Bamford/JCB hydrogen thesis in one convenient package. That was politically powerful. But the commercial weight is in battery-electric buses: larger orders, repeatable fleet deployment, depot learning, supplier maturity and production scale. Hydrogen remains visible, and Wrightbus can continue to sell hydrogen buses where buyers and funding support them. The business gravity, however, is electric.
