Electrolysis Plant

The purpose of water electrolysis process is to produce hydrogen for use in ammonia making. The electrolysis process consists of 14 electrolytic units. Electrolysis of water at Sable is a process whereby 6.5 kA direct current is applied across each electrolytic unit to separate water into hydrogen and oxygen both at 35°C and 30 bar. An electrolyte consisting of 25% wt/wt Potassium Hydroxide, the other part being demineralised water, is used as feed to the electrolytic units. 90MW are required to run all electrolytic units at capacity.
