    Large-scale electrolysis' role in global decarbonization

    May 24, 2021 Large-scale electrolysis' role in global decarbonization. The world is racing to drastically lower greenhouse gas emissions and limit the earth's warming to 1.5 degrees from pre-industrial levels. To reach this goal, 189 parties, representing the producers of 83 percent of global emissions, have ratified the Paris Climate Agreement

    Alkaline water electrolysis is known as the principal process for the water splitting reaction. Military applications related to the use of hydrogen isotopes boosted the development of this technology. The first plants for the electrolysis of D 2 O (D 2 production) were built in Norway. Nowadays, several companies are producing alkaline

    water is broken into hydrogen and oxygen. It is an expensive process. Alkaline electrolysis costs $500/kW and PEM electrolysis costs $1000/kW [Kato 2005]. These costs make process efficiency all the more important. If electrolysis efficiency is 71%, then 5000 kWh of electricity production would result in the generation of 500 Nm3 of oxygen
