How do they make liquid hydrogen
WebHydrogen production is the family of industrial methods for generating hydrogen gas. As of 2024, the majority of hydrogen (∼95%) is produced from fossil fuels by steam reforming … WebJun 3, 2024 · In theory, it's easy to make water from hydrogen gas and oxygen gas. Mix the two gases together, add a spark or sufficient heat to provide the activation energy to start the reaction, and presto—instant water. Merely mixing the two gases at room temperature, however, won't do anything, like hydrogen and oxygen molecules in the air don't ...
