On 17th June 2021, the Neptune project jointly held an online workshop, together partners from with the Pretzel project, covering the topic ‘Game Changer Proton Exchange Membrane (PEM) Water Electrolysers’. The aim was to discuss next generation polymer electrolyte membrane electrolysers, with novel solutions at intermediate Technology Readiness Level, contributing to step changes in performance. The workshop attracted 59 participants from several different countries with both industry and academia represented.
The morning session was dedicated to funded projects in the field of water electrolysis, focusing on those projects with a game changing aspect to the scope. The workshop was opened with a welcome from the project coordinators of the Neptune and Pretzel projects and a keynote lecture from Nikolaos Lymperopoulos, FCH JU Project Officer presenting ‘FCH JU past and future support to electrolysis development and demonstration’. Invited speakers from key European projects described the project overviews and recent technical advances made within those projects. The invited speakers from the projects were Rachel Backhouse (ITM Power, UK, Neptune), Aldo Gago (DLR, Germany, Pretzel), Daniel García Sánchez (DLR, Germany, Promet-H2), Lisa Ruf (Element Energy, UK, Oyster), and Corneliu Marius Craciunescu (Politehnica University Timisoara, Romania, CoDePEM).
In the afternoon session, presentations from international experts in the field focussed on specific topics such as electrocatalysts, membranes, MEAs, PTLs, stacks and systems. The afternoon was opened by Peter Strasser from Technical University of Berlin, Germany with a presentation on the topic of ‘Oxygen evolution catalysts for PEM water electrolyser anodes’ followed by a presentation on ‘A 9+ Years Journey in Aquivion Membrane Development for Electrolysis: from ELECTROHYPEM to NEPTUNE’ from Claudio Oldani (Solvay Specialty Polymer, Italy). Daniel Greenhalgh (ITM Power, UK) presented ‘Stack and System Development at ITM Power’ and Felix Büchi (Paul Scherrer Institute, Switzerland) gave an insight on the subject ‘Towards understanding of the key properties of porous transport layers’. A link to demonstration activities and national plans for developing advanced green hydrogen production technologies was provided by Laila Grahl-Madsen (IRD Fuel Cells, Denmark) discussing the ‘Implementation plan in Denmark’.
Two round table discussions were held, providing opportunities for participants to interact with specific discussions about material development, degradation effects, stack and system development. The day was concluded by an overview from Nikolaos Lymperopoulos, representing the FCH JU.
Finally, we would like to thank all the participants, it was a very interesting day with high level presentations.
