100 kg Ammonia production requires ~18 kg Hydrogen
100 kg Urea production requires ~ 46 kg Ammonia
100 kg DAP (Di-Ammonium Phosphate) production requires ~ 18 kg Ammonia
Generally, specified electrolyser capacity (in MW) refers to the input electricity consumption per hour. To derive Hydrogen production per hour, divide the capacity by the Specific Energy Consumption (kWh / kg) of the electrolyser. E.g. A 1 MW electrolyser with Specific Energy Consumption of 50 kWh / kg will produce 20 kg Hydrogen per hour.
