RS-25 engines powering NASA's SLS (Space Launch System) rocket use liquid oxygen and liquid hydrogen as propellants – the same elements that combine to create water (H2O). For an RS-25 engine test, liquid hydrogen and liquid oxygen are mixed in the engine combustion chamber and ignited, which results in extremely high-temperature exhaust (up to 6,000 degrees F) exiting the nozzle into the flame deflector at a very high rate and pressure. Hundreds of thousands of gallons of water also are flowing

The world’s first hydrogen propulsion superyacht ‘BREAKTHROUGH’. Built by Dutch yard Feadship and delivered in 2025, Breakthrough uses a large scale hydrogen fuel cell system with cryogenic liquid hydrogen to power hotel loads and coastal cruising with zero emissions and only water vapor as a byproduct, while hybrid diesel-electric systems provide extended range when needed.  Originally commissioned as Project 821 for billionaire tech figure Bill Gates, the 118.8m vessel was completed after a f
