Breakthrough study enhances efficiency and sustainability of green hydrogen production.

Green hydrogen is seen as one of the key solution for achieving net zero target by 2050. This ambitious decarbonisation goal relies on successful deployment electrolysis technologies, in particular PEM Electrolyser, which is known for its efficiency, compact design, and ability to work well with renewable energy sources. While PEM Electrolyser is starting to be used commercially, there are still uncertainties about its future environmental impact. To address this, PEM cells need to be designed with a focus on using materials more efficiently, particularly through improvements in electrochemical catalysts, membranes, and electrodes.

As reported in this paper, Michael et. al. simulated a 10MW PEM Electrolyser plant to identify important operational factors and assess future development scenarios for the membrane electrode assembly (MEA). They examined how these scenarios affect energy use, material efficiency, and system durability. Their findings highlight the trade-offs between energy and material efficiency, offering insights to reduce environmental impacts.

This research is important for enhancing the environmental and operational performance of PEM Electrolyser plants. Full paper is available from Procedia CIRP

Michael will present this work at the 31st CIRP Conference on Life Cycle Engineering (LCE 2024) this month in Turin, and he is looking for opportunity to work closely with industry partner. Please get in contact if you are interested to host Michael!
