Electricity is 60 to 80% of the cost of green hydrogen, and most electrolyzers use far more of it than they need to. The theoretical minimum to split water into hydrogen is 39 kWh per kilogram, but real systems typically consume 50 to 55 kWh, a gap that drives up the price of every kilogram produced.
This video explains the four levers that actually cut electrolysis energy use: raising cell electrical efficiency, reducing internal losses in the stack architecture, cutting energy wasted on idle and cycling, and lowering the cost of the input electricity through better renewable power matching. Conventional alkaline and PEM electrolyzers were built for steady baseload power, so when they're connected directly to variable solar or wind, they lose efficiency and degrade faster, forcing operators to add costly battery or grid backup.
H2Pro's Decoupled Water Electrolysis (DWE) is a membraneless design built at ambient temperature to cycle on and off without that degradation, aimed at running directly on intermittent renewables. H2Pro is scaling from a 0.5 MW pilot in Israel toward a 5 MW off-grid solar demonstration in Spain.
