Nora Han, ABB System Drives, Switzerland, outlines the importance of efficient power supply in green hydrogen production.
oday, over 99.6% of hydrogen processing involves petroleum and natural gas. This is unsustainable and does not make net zero goals any more achievable. As the hydrogen industry shifts to focus on producing green hydrogen, there is one major obstacle to overcome: the cost. Assuming that water is relatively affordable, electricity is an electrolysis facility’s greatest OPEX. In an average green hydrogen plant, electricity accounts for approximately 80% of OPEX. Therefore, improving the energy
efficiency of a facility is the best way to lower the unit cost of green hydrogen. Fortunately, technological advances in power supplies mean that greater efficiency is now possible. These developments, in combination with other economic factors, will earn green hydrogen its place as the fuel of the future.
A clear way to improve energy efficiency A green hydrogen processing system involves many components, and
