Cummins looks to hydrogen ICE engines

Internal combustion engines powered by hydrogen regarded as interim decarbonisation solution

Automakers are announcing plans to develop hydrogen-fuelled internal combustion engines (ICEs) for vehicles as an interim decarbonisation measure, given the time it will take to improve the economics of high-cost hydrogen fuel cell engines. Indiana-based Cummins, a leading maker of diesel engines, revealed a plan in September to develop medium-duty 6.7-litre and heavy-duty 15-litre engines fuelled by hydrogen following preliminary testing over the summer. British heavy machinery maker JCB is also researching hydrogen-fuelled ICE engines for its excavators and other vehicles, while Toyota is planning to launch hydrogen combustion versions of the Prius and Corolla by 2025.
