The hydrogen combustion engine has a peak at high load and can achieve similar efficiency levels as a hydrogen fuel cell. [34] From this, one can deduce that hydrogen combustion engines are a match in terms of efficiency for fuel cells for heavy duty applications. Efficiency decreases for small internal combustion engines.

In 1970 Paul Dieges patented a modification to internal combustion engines which allowed a gasoline-powered engine to run on hydrogen. [114] Mazda has developed Wankel engines burning hydrogen, which are used in the Mazda RX-8 Hydrogen RE. The advantage of using an internal combustion engine, like Wankel and piston engines, is the lower cost of ...
Arvin Meritor, a Tier 1 supplier of automotive technology, at one time, was experimenting with a plasma reformer technology which would use hydrogen produced from the fuel to enhance engine combustion efficiency and reduce emissions of NO x. [26] This reference states that a 20% to 30% increase in engine thermal efficiency is possible. However ...

In 2008, The Boeing Fuel Cell Demonstrator achieved straight-level flight on a crewed mission powered by a hydrogen fuel cell. 2008 - Aircraft, Boeing [80] 2015 - Drone, Intelligent Energy, UK tested successfully Drones with Hydrogen fuel cell engine. [81] 2016 - HY4 is the first passenger aircraft in Germany. [82]
Tenneco is working to accommodate growing demand to find H 2-ICE solutions for hard-to-abate mobility sectors.; The H 2-ICE test cell in Burscheid, Germany, operational since Q4 2022, was expanded with two additional cells, and a fourth new H 2-ICE test cell was recently commissioned in Ann Arbor, Mich.
It is a common liquid rocket fuel for rocket applications and can be used as a fuel in an internal combustion engine or fuel cell. Various concept hydrogen vehicles have been lower volumetric energy, the hydrogen volumes needed for combustion are large. Hydrogen was liquefied for the first time by James Dewar in 1898.
