Industry Update
Bosch develops chemicalfree water treatment technology for electrolysis Bosch has announced that it plans to launch its water treatment systems for use in green hydrogen production in 2024 . Designed by Bosch Manufacturing Solutions , the new systems eliminate the need for chemicals in water treatment , making them environmentally friendly , according to the company .
The Bosch systems remove minerals from the water by means of thermal and electrochemical processes to obtain ultrapure water . Thanks to a treatment process without filter media , it is possible for operators to completely dispense with the use of chemicals . “ Green hydrogen is sustainable only if its production doesn ’ t cause collateral damage to the environment ; for example , by putting chemicals into our already heavily polluted waters ,” said Dr . Wolfgang Schleifenbaum , head of the Hydrogen business unit at Bosch Manufacturing Solutions . For predictive maintenance of the equipment , even from far away , Bosch offers software solutions that ensure robust operation in harsh environmental conditions .
For water treatment in developed areas , Bosch plans to expand its portfolio to include industrial systems that use reverse-osmosis processes and ion exchangers to turn tap water into the ultrapure water electrolyzers need . With this combination of industrial and specialpurpose equipment , the company aims to fulfil the requirements for electrolysis projects worldwide .
H2U Technologies successfully demonstrates non-iridium PEM electrolyzer H2U Technologies has announced the successful demonstration of the first non-iridium PEM electrolyzer for commercial hydrogen production , marking a significant milestone for the company as it moves closer to the goal of reducing the costs of green hydrogen production .
At the end of 2022 , California-based H2U proved the efficacy of its non-iridium catalyst materials in smallscale electrolyzer stacks . Since then , the company has scaled this technology to a 200kW electrolyzer system for in-house testing and demonstration . This significant achievement is a crucial step toward H2U ’ s goals of alleviating iridium supply chain constraints on the growing electrolyzer industry .
During the in-house demonstration of its 200kW iridium-free electrolyzer system , the H2U team is collecting operational data to further validate the durability and performance of novel non-iridium catalysts at the commercial scale . The company will apply those lessons learned to the design review and construction of their first external proof-ofconcept units set to ship at the end of this year .
