Horizon Europe project. PressHyous (PRESSurized HYdrogen prOdUced by high temperature Steam electrolysis) project has started on September 2023. 👉 https://linktr.ee/presshyous_he The European Commission has identified the production and use of clean hydrogen has key lever for the industry decarbonation. Solid Oxyde Electrolysers appear to be a competitive solution to help reaching the clean H2 production level set by the EU. H2 compression is energy-intensive, producing pressurised H2 directly in the electrolyser will bring major relief on the compression costs, the technological complexity and the process efficiency with a potentially smaller footprint. PressHyous, an EU R&D project funded by the Clean Hydrogen parthership, aims to produce low-carbon pressurised H2 at reduced cost, around 3€/kg by 2030. The concept will be proven through the operation of a 20 kWe pressurised lab-scale device (eq. 13.5 kg of pressurized H2/day). This lab-scale device will be composed of a Solid Oxide Electrolysis (SOEL) stack located in a pressurised vessel, and will be operated up to 30 bar at least at 1 A/cm2 close to the thermoneutral voltage during 4000 hours. The project also aims to investigate an innovative stack concept, without pressure vessel, thus reducing the cost of Balance of Plant, by testing this solution up to 10 bar at a short stack scale, at similar current density to the stack operated in the pressurised vessel. To reach the set objectives, both stacks will integrate optimised components, notably electrochemical cells and sealings, improved for operation under pressure. To complement the practical testing of the PressHyous concepts, the project will deliver model-based insights for H2 production under pressure for up to 5 identified use cases, on expectable performances of both stack concepts (with or without pressurised vessel) towards large scale developments up to 100s MWe, coupled with techno-economic and life-cycle analysis.
