DOE: global electrolyzer sales reached 100 MW per year in 2017

Global sales of electrolyzers in 2017 were estimated to be 100 megawatts per year, according to the US Department of Energy (DOE).

That is enough to produce approximately 50,000 kilograms of hydrogen per day (assuming 50 kWh/kg, running full time).

During electrolysis, an electrolyzer uses electricity to split water molecules (or H2O) into hydrogen and oxygen.




For proportion:  1 kg H2 has the energy of about 1 gallon gasoline.

The USA burns about 370 million gallons of gasoline PER DAY.


In proportion to current ICEVs (gasoline and diesel) BEVs and FCEVs are NOT YET major contributors. However, this will change progressively by 2025/2030/2040 and by 2050 or so, most ICEVs may become museum pieces?

H2 from clean REs will become common place.


USA burns 370 million gallons of liquid fuel per day because they (and we) continue to use oversized, heavy grossly inefficient (10 to 15 mpg) gas guzzlers.

A mix of HEVs, PHEVs, BEVs and FCEVs could reduce daily consumption to 50-70 million gallons.

Unfortunately, short of progressive heavier FED gas taxes on fossil and bio-fuels, polluting guzzling ICEVs may be around for another 30 to 50 years.
