Despite the production costs associated with green hydrogen, the gas has many attractive properties as a future fuel source. With over three times the energy of petroleum per unit of mass and zero carbon emissions, hydrogen works well when used in conventional combustion engines but also as a source of heat for homes.
Unlike electricity, hydrogen distributed production is possible wherever renewable energy and a water source are present. Hydrogen can fill gaps in the renewable grid when stored in high-pressure tanks when solar or wind farms cannot produce energy.
