Abstract
Many nations are rapidly increasing electrical generation capacity from renewable energy sources (RES) such as wind and solar. The wide penetration of RES requires an energy storage solution which has come in the form of hydrogen generated via polymer exchange membrane (PEM) electrolysis. A study of the current state-of-the-art PEM electrolysis indicates that the largest PEM-based stacks range from 150 – 250kW and that a significant scale-up of the technology is required to accommodate multi-Megawatt (MW) energy storage solutions in large-scale RES applications.
