Hydrogen-powered vehicles are already here. Internal combustion hydrogen engines are being used in commercial applications in Europe, while numerous automakers globally have patents for hydrogen engines for both commercial and performance applications. Just like gas or diesel mills, air is mixed with fuel to make horsepower. And Cummins already has a special turbocharger to force-feed these new engines, called the CCS H2 ICE.
It’s a variable geometry turbo designed to “meet the unique requirements of hydrogen engines,” according to Cummins. The exact details of the design aren’t shared, though it’s said to incorporate a bespoke aerodynamic design that caters best to hydrogen, which has a lower density compared to gasoline or diesel. A by-product of burning hydrogen is water, and being a turbocharger, it’s driven by the engine’s exhaust system. As such, the…
