EDITORIAL: Hydrogen ICE is heating up

In the past three months, at least four major announcements have detailed the kickstart of development programs or real-world demonstrations of hydrogen-fueled internal combustion engines (ICE). As OEMs and fleets look to accelerate the decarbonization of their product portfolios, engine makers are ramping up efforts to provide another alternative.

“Hydrogen internal combustion engines are emerging as a key technology to eliminate carbon emissions from heavy-duty sectors, while retaining the power density and operational range typical of diesel engines,” Jim Nebergall, General Manager - Hydrogen Engines at Cummins, said in an October statement detailing a collaboration with Terex Advance Mixer, end user Edge Materials and hydrogen producer PCC Hydrogen.
