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 ...
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]
Hydrogen fuel enhancement is the process of using a mixture of hydrogen and conventional hydrocarbon fuel in an internal combustion engine, typically in a car or truck, in an attempt to improve fuel economy, power output, emissions, or a combination thereof.
Rotary engines of the Wankel design are used in some automobiles, aircraft and motorcycles. These are collectively known as internal-combustion-engine vehicles (ICEV). [18] Where high power-to-weight ratios are required, internal combustion engines appear in the form of combustion turbines, or sometimes Wankel engines.
