The most economical sources of hydrogen production are still
natural gas and coal, but these processes are also
liberating large quantities of CO2. Production of green hydrogen through
electrolysis remains quite
costly, because producing all of today’s dedicated hydrogen output from electrolysis would result in a global electricity demand of
3600 TWh, which is more than the total
annual electricity generation of the European Union . So, production cost dictates the accessibility to green hydrogen. And Knowing that only 20 % of European Union needs in energy (all sources combined) are currently met by electricity and that only
7% of it is produced from renewable energy sources, an alternative method not utilizing electricity to produce green hydrogen could be a much needed solution.
