The UK-based firm plans to decarbonise hard-to-electrify vehicles such as fire engines, ambulances, and HGVs with its new range.

The loan marks a step beyond UlemCo’s existing dual fuel hydrogen technology, which allows diesel engines to run partly on hydrogen. The new range will deliver fully zero-emission options, combining electric motors with hydrogen combustion or fuel-cell systems.

“Our dual fuel solution enables them to quickly convert existing vehicles and reduce the use of fossil fuels,” explained Amanda Lyne, founder and Managing Director of UlemCo.

“However, our goal has always been to offer zero emissions solutions too. We know that for many applications, battery technology is not only very expensive, but it cannot match the operational needs of fleets.

“Therefore, we are excited about our new range, which will enable customers to fully decarbonise their existing vehicles at a much more affordable cost.”

The announcement comes as the UK government invests £500m ($653m) to build regional hydrogen transport and storage infrastructure, which is expected to boost demand for hydrogen-powered fleets.

Rob Horby of Mercia Ventures, which led a £5m ($6.5m) financing round in UlemCo last year, said the company “will be well positioned to take advantage of the growing demand.”
