22 Facts About Hydrogen economy

Hydrogen economy is using hydrogen to decarbonize economic sectors which are hard to electrify, essentially, the "hard-to-abate" sectors such as cement, steel, long-haul transport etc.

Hydrogen economy can react in a fuel cell, which efficiently produces electricity in a process which is the reverse of electrolysis of water.

The hydrogen economy is nevertheless slowly developing as a small part of the low-carbon economy.

Idea of hydrogen economy has been heavily criticized from the moment it was proposed.

Hydrogen economy can be an environmentally cleaner source of energy to end-users, without release of pollutants such as particulates or carbon dioxide.
