Scaling‐up PEM Electrolysis Production: Challenges and Perspectives

Abstract

AbstractElectrolysis is fundamental to meet the Paris agreement targets, as it serves as an energy storage technology, with hydrogen being a major energy vector to decarbonize the industry sector. In particular, proton exchange membrane (PEM) electrolysis is well suited for coupling with renewables such as wind turbines and PV. The worldwide objectives for hydrogen ramping up are very ambitious and can only be satisfied with rapid and efficient production. This paper describes how the giga‐factory from Siemens Energy installed in Berlin will play a significant role in satisfying the rising demand of PEM stacks for the company. In addition, challenges such as catalytic material shortage and the need for industrial eco‐systems are discussed.
