ULEMCo on Hydrogen Injection For Commercial Vehicle Propulsion
ULEMCo, founded by Amanda Lyne in 2014, offers hydrogen dual fuel technology, working with fleets to highlight the benefits hydrogen could bring.
She says: “Hydrogen as a fuel will allow people to have zero tailpipe emissions without changing their duty cycle and behaviour. Quite simply, we need to crack on and not just talk about it.”
Lyne maintains that hydrogen is as close to conventional technology, in terms of operational use, as possible. Electric vehicles are feasible for certain things but, she argues, they aren’t going to be suitable for everything and will also require a lot of changes to duty cycles.

The ULEMCo solution is relatively straightforward. The only major changes, says Lyne, over an existing set-up is to add some form of hydrogen storage and integrate gas injectors into the engine.

“Our aim is to offer decarbonisation,” she explains. “We recognise that Euro VI technology [and it doesn’t work with older tech] is primarily about air quality emissions, so by using hydrogen instead you are helping decarbonisation.
“As far as our technology is concerned, we calibrate the engine and map our hydrogen to ensure the vehicle works exactly the same [as a diesel],” continues Lyne. “We do that to make sure the driver doesn’t notice any difference, and also to at least equal the NOx level of diesel – or even improve it. We inject hydrogen at the times when all of those factors come together. So we will use more hydrogen in a vehicle that’s operating at low speed and low torque than we would do than if it was running flat out on the motorway.
“That’s why refuse trucks work very well, because there’s a great engine to move the heavy weight, but when it’s moving it’s not really doing a lot, so then we can use more hydrogen.”
