Hydrogen production

Hydrogen production

+

Hydrogen production is the family of industrial methods for generating hydrogen gas. As of 2020, the majority of hydrogen (∼95%) is produced from fossil fuels by steam reforming of natural gas, partial oxidation of methane, and coal gasifiion. Other methods of hydrogen production include biomass gasifiion, no CO 2 emissions methane pyrolysis, and electrolysis of water.

Chemical Energy to Thermal Energy Examples

+

1. Coal is burned at a power plant. The chemical energy released as the coal is burned heats water and turns it into steam. The chemical energy causes the liquid water molecules to move faster increasing their thermal energy. 2. Gasoline is burned in a car engine. As the gas burns, small explosions release heat or thermal energy which makes the ...
