The main objective of REMEDHYS is to advance the maturity of aboveground solid-state hydrogen storage solutions based on metal hydrides with hydrogen chemically bounded to the metals, and operation at ambient conditions. This is a compact and safe hydrogen storage method, and with significant advantages compared to both compressed and liquid hydrogen storage solutions. The hydrogen storage system in REMEDYS with capacity of 100 kg H2 will operate at a pressure below 50 bar. The metal hydrides will be produced from low-cost recycles metals sourced in Europe, and then minimizing the needs to import critical raw materials to Europe. The modular hydrogen storage system will be validated in an end-user scenario with a 2 MW PEM electrolyzer and supplies of hydrogen to a hydrogen-powered offshore service supply vessel. REMEDHYS will contribute to implementation of regulations, codes, and standards for large-scale aboveground storage systems for solid-state hydrogen storage systems. The project will also address sustainability and circularity aspects by employing a Life Cycle Assessment and make recycling of critical raw materials as an integrated part of the materials development. The REMEDHYS consortium consists of the leading research institutions in Europe on solid-state hydrogen carriers; four research centers and two universities, and four partners from the industry. REMEDHYS will build on the experiences from the EU funded project HyCARE, 2019-2023, which had six of the REMEDHYS partners.
