Introduction from the coordinator
Sustainable hydrogen generation by water electrolysis using renewable electrical energy is a very promising technology for the next energy system. Polymer electrolyte water electrolysis is characterized by excellent efficiency and appropriate dynamic characteristics for storing renewable energy in hydrogen. This can efficiently address the gap between intermittent renewable power production and grid demand while hydrogen can become the future energy vector.
Increase in hydrogen production rate - by ITM Power
ITM Power increases hydrogen production rate of its PEM Water Electrolyser three-fold observing negligible impact on degradation during laboratory stack testing
The large-scale deployment of wind power and solar energy sources will strongly contribute to the implementation of Europe’s energy policies objectives i.e. to produce 65% of electricity from renewable energy sources by 2050 and to reduce CO2 emissions linked to energy production by 50%.

PGM (precious group metal) amount in PEM catalyst layers - by EWII
One of the ambitious targets in HPEM2Gas is to lower the amount of precious group metal (PGM) in the catalyst layers without jeopardizing good performance or durability. The specific target is to reduce the total PGM loadings down to 0.5 mgPGM/cm2 or below. Good results are obtained e.g. the cathode PGM loading has been reduced by a factor of five without significant loss of performance nor durability (Figure below). Furthermore, prolonged single cell test show encouraging low degradation rates in steady state test.

High performance nanostructured Ir-Ru-oxide electro-catalyst - by CNR
CNR-ITAE has recently developed high performance nanostructured Ir-Ru-oxide electro-catalysts with core-shell structure. This electrocatalyst when operated with stabilized Aquivion® membranes and ionomers developed by Solvay Specialty Polymers has allowed to achieve an electrolysis current density of 3 A cm-2 at a cell potential <1.8 V (>80% enthalpy efficiency) with a low catalyst loading (<0.34 mg cm-2) while showing more than 4000 h stable performance (<8 µV/h degradation rate).
