[ industry update ]
Hystar officially opens its HyPilot project On 18 November , Hystar hosted an event at the Kårstø Gas Processing Plant in Rogaland , Norway , to formally open its field project , HyPilot . The Kårstø plant is hosting the HyPilot project at its K-Lab test centre . HyPilot is the in-field demonstration of Hystar ’ s 1.5-MW containerized PEM electrolyser . The project will provide performance data from various operating regimes , including intermittent power supply .
Fredrik Mowill , CEO of Hystar , said : “ HyPilot marks an important juncture both for Hystar and for the global green hydrogen industry . The project allows us to showcase our patented , ultra-efficient electrolysers , and the exceptional benefits of our unique design and scalable technology can bring to the industry . We are
grateful to Enova and our partners , Equinor , Yara Clean Ammonia , Gassco , and ABB for their collaboration and support .”
Cork composite sealing solutions proven in 100 % hydrogen environment Amorim Cork Composites has tested two cork-based materials , cork & EPDM and cork & NBR , which have proven to provide excellent sealing in a 100 % hydrogen environment , marking a significant advancement in the development of sustainable cork solutions for hydrogen sealing .
The test was conducted in accordance with European standard EN 13555 , a recognised methodology for assessing the stress and impermeability of sealing joints under pressure conditions . However , deviating from the standard practice , hydrogen was used as the test gas instead of helium .
The sealing joints were prepared with DN40 / PN40 dimensions , with an outer diameter of 92 mm , an inner diameter of 49 mm and thickness of 3 mm . A servohydraulic press ( TEMESfl . ai1 ) was used to apply and measure the stress , with loading and unloading cycles to assess the leakage rates . Hydrogen was maintained at 10 bar , and leakage rates were measured at different stress levels : from 2 MPa to 20 MPa for cork & EPDM and from 4 MPa to 40 MPa for cork & NBR .
Seals play a crucial role in sealing hydrogen technologies , as even small leaks can pose significant safety risks and cause operational inefficiencies . The test results confirm the reliability of these materials for storing and transporting hydrogen , underscoring their potential to maintain safety and efficiency in hydrogen-rich environments .
Future tests could expand on these findings by evaluating new materials and testing under varying temperature and pressure conditions , simulating more extreme environments commonly found in industrial hydrogen applications .
