Luxembourg-based SISTO Armaturen S.A., a key member of the esteemed KSB Group, has been awarded a significant contract to supply valves for a groundbreaking pilot electrolyser project in Herne, Germany. This pivotal initiative is part of a joint effort by Evonik and Siemens Energy under the collaborative banner of H2annibal.
SISTO Armaturen S.A. will contribute a range of valves, including pneumatically actuated SISTO-20 diaphragm valves and SISTO-RSK swing check valves, meticulously selected for their suitability for the unique requirements of the pilot electrolyser. Operating on the proton exchange membrane (PEM) principle, the electrolyser demands precision and reliability, qualities exemplified by SISTO’s valve solutions.
The SISTO-20 diaphragm valves, tailored for the electrolyser’s specifications, feature a design that minimizes contact between the fluid and valve components, ensuring durability and optimal performance. With a focus on longevity, these valves boast rear support for the diaphragm, enhancing their service life—a critical factor in electrolysis operations.
Additionally, the SISTO-RSK swing check valves, designed to handle deionized water, feature rubber-lined interiors for superior performance. Their compact design minimizes system footprint, facilitating efficient operation and installation.
This project marks a significant milestone in Germany’s transition to sustainable energy solutions. The H2annibal initiative aims to produce green hydrogen through an 8 MW pilot plant in Herne, Germany, with the hydrogen serving as a vital raw material for isophorone diamine production—a key component in manufacturing wind turbine rotor blades. By replacing grey hydrogen derived from fossil sources, the pilot plant is expected to yield significant reductions in carbon emissions, estimated at up to 12,000 tonnes of CO2 per year post-commissioning.
SISTO Armaturen S.A.’s involvement underscores its commitment to driving innovation in fluid handling technology for sustainable energy applications. With a proven track record in electrolysis plants globally, SISTO’s valves are poised to play a crucial role in facilitating efficient and reliable operations at the forefront of green hydrogen production.
As the pilot electrolyser project in Herne progresses, the collaboration between SISTO Armaturen S.A., Evonik, and Siemens Energy represents a significant step towards realizing the potential of green hydrogen as a key contributor to a cleaner, more sustainable energy future.
