" Every gas turbine project we supply today includes a hydrogen option.”
building energy infrastructure that is hydrogencapable,” Drehmel notes.“ It’ s a global trend.”
These projects are anything but small; some of the installations PRUSS supplies reach up to 593 MW in capacity, highlighting the critical role their valves play in some of the world’ s largest hydrogen-ready power plants.
A typical package from PRUSS includes up to 14 valves – highly precise control valves with integrated shut-off functions, supported by quickacting emergency shut-off valves. Designed to handle gas temperatures exceeding 300 ° C, these valves are made from carefully selected materials that can withstand the embrittlement risks and other challenges associated with hydrogen at elevated temperatures.
segments.“ We are a high-pressure valve specialist, so storage and transport systems are not our focus,” Drehmel explains.“ But in hydrogen production, we see opportunities – particularly in oxygen recovery from electrolysis.”
Wet oxygen, a by-product often vented to the atmosphere, presents a promising application.“ We’ re working with clients on systems to recover and reuse this oxygen at industrial scale,” says Drehmel.“ We believe there is untapped potential in this area, and our engineering team is closely collaborating with partners to develop robust, safe, and cost-effective valve solutions.”
Meanwhile, PRUSS has made headway in cryogenic valve technology. Targeting applications such as bypass valves in compression stations and pressure reduction from liquid hydrogen storage to gasification, the company is developing a multistage, metal-sealed solution.“ The aim is
These solutions are tailored for demanding conditions, offering rangeabilities up to 500:1, which allows for highly responsive and accurate flow control, especially during ignition and load changes. This level of control not only enhances safety and efficiency but also helps reduce overall system costs by eliminating the need for multiple valves performing similar functions.
While details remain confidential, PRUSS has also developed a new valve series tailored to a leading turbine model in the 60 Hz market.“ This model is expected to become the new workhorse,” Drehmel says.“ We’ re prepared to handle the expected ramp up to several dozen in the coming years.”
