GSR Ventiltechnik develops new valve series for electrolyzers GSR Ventiltechnik GmbH & Co . KG has developed a new valve series for the hydrogen sector . The direct-pressure controlled valves are characterized by a long service life , achieved through the unique design of the stem seal , enabling 35 % more switching cycles than comparable competitive products , according to the company .
The new externally controlled valves control the processes surrounding electrolysis .
A version for use in both the hydrogen and oxygen processes will soon be available . The body materials have been specially qualified for use with H 2 or O 2
. The hydrogen version has reliable , tested sealing elements , while these are even BAM-certified for the oxygen version .
The valves are optimally designed for the prevailing pressure and temperature ranges , have excellent flow characteristics , and feature sophisticated materials that ensure a long service life . They have high tightness ( 10-6 mbar l / s ) and are ATEX certified . SIL2 acceptance is planned .
ANDRITZ wins first order in green hydrogen sector Koppö Energia of Finland has selected international technology group ANDRITZ to perform the Front-End Engineering Design ( FEED ) for a large-scale plant to produce green hydrogen . This order is a milestone in ANDRITZ ’ s strategy to become one of the world ’ s leading industrial partners for large-scale green hydrogen production plants .
The plant , with a capacity of 200 MW , will be built in Kristinestad , Finland as part of a Power-to-X project . The customer , Koppö Energia , is a joint venture of Germany-based Prime Capital , a renowned asset manager specializing in alternative energy projects , and CPC Finland , a subsidiary of project developer and green power producer CPC Germania .
The FEED provided by ANDRITZ will include the complete hydrogen plant , incorporating the alkaline electrolyzer technology of HydrogenPro . Based on the design , the joint venture intends to place the order for the Engineering , Procurement and Construction ( EPC ) of the green hydrogen production plant at the beginning of 2024 .
The hydrogen in Kristinestad will be produced using renewable energy , mainly wind power . Up to 500 MW of wind and 100 MW of photovoltaics power will be developed under the Koppö Energy Cluster to supply the green hydrogen plant with electricity .
ITM partners with Mott to advance PEM electrolysis components ITM Power has announced it is partnering with Mott Corporation to further advance porous transport layers ( PTL ), which are a key component of proton exchange membrane ( PEM ) electrolysis .
ITM claims that its stacks operate at the highest current density on the market , which results in lower stack cost due to reduced material use . The high current density brings very specific requirements for the PTL , which Mott have demonstrated capability to deliver . The two companies are working together to further enhance the efficiency and performance of ITM ’ s PEM electrolysis technology and to develop ITM ’ s next-generation stack . ITM will work alongside Mott ’ s engineering teams to design and verify component customisation in support of its ongoing technology roadmap .
PTL distribute electrical current and fluids uniformly across the surface of the membrane . Through optimisation of the PTL , the performance of the core technology is maximised while providing a precise mechanical environment promoting long-term stability .
