Hydrogen Energy Earthshot19 goal of reducing the cost of producing carbon-free hydrogen to $1/kg. Carbon-free hydrogen is already being produced at commercial scale with electrolysis coupled with renewable energy, but the costs of electrolysis and renewable. energy need to be reduced for this Figure 2: Electrolysis.

IEA analysis finds that the cost of producing hydrogen from renewable electricity could fall 30% by 2030 as a result of declining costs of renewables and the scaling up of hydrogen production. Fuel cells, refuelling equipment and electrolysers (which produce hydrogen from electricity and water) can all benefit from mass manufacturing.

An atom of hydrogen has only one proton and one electron. Hydrogen gas is a diatomic molecule—each molecule has two atoms of hydrogen (which is why pure hydrogen is commonly expressed as "H 2"). At standard temperature and pres sure, hydrogen exists as a gas. It is colorless, odorless, tasteless, and lighter than air.

Hydrogen is stored and can be re-electrified in fuel cells with efficiencies up to 50 percent. A fuel cell generated electricity through an electrochemical reaction instead of a combustion. See the diagram below for a depiction of a hydrogen fuel cell. Hydrogen storage is unique. Hydrogen can be tanked like propane or turned into a powder.
