Cost-effective and high-capacity hydrogen compression in a wide pressure range is an important component for enabling fossil-price parity of green hydrogen for Power-to-X (PtX) and transport fuel onwards 2030. This calls for substantially reduced CAPEX and OPEX costs and improved efficiency and reliability for hydrogen compression compared to state-of-the-art, through pursuing new innovations and designs. This requires pioneering new design solutions to address the unique challenges of hydrogen compression, such as material degradation and leak tightness under high-pressure conditions and ensuring structural integrity to prevent component failures.
Innovations might include exploring novel design for currently used materials or the development of new materials resistant to hydrogen embrittlement and high-temperature hydrogen attack, and advanced leak detection and mitigation systems. Furthermore, innovations could include disruptive and breakthrough enhancements with a strong emphasis on solutions that can withstand varied operational stresses.
Previous EU-funded projects[1] e.g electrochemical compression (PHAEDRUS[2]), thermochemical compression (COSMHYC[3], COSMHYC XL[4] & COSMHYC DEMO[5]), hydraulic boosters (H2Ref[6] & H2Ref Demo[7]), are helping to progress hydrogen compression towards achieving the Clean Hydrogen JU SRIA 2024 targets. However, for hydrogen compression to contribute to enabling fossil-price parity a further stretch towards the SRIA 2030 targets is required.
