Tecnalia develops a pioneering electrolyser to test hydrogen production technologies.

Tecnalia has developed an innovative electrolyser capable of testing different technologies for hydrogen production. The prototype is an experimental bench that enables companies to test the different components of an electrolyser, mainly its core or stack, operating at a power of approximately 50 kW and with a hydrogen production capacity of around 1 kg/h. With its commissioning, the technology centre is now starting tests and demonstrations with national and international companies at its facilities.

The electrolyser is located in the laboratory for the development of technologies for the production, storage, transport, distribution, use and safety of hydrogen that Tecnalia opened last year at its facilities in Donostia-San Sebastián, where more than 50 projects are currently underway for the research and validation of hydrogen technologies, as well as their scaling up to accelerate their industrialisation.

The test bench is capable of testing two of the four technologies capable of producing green hydrogen: alkaline and AEM. Designed entirely by Tecnalia, this prototype will be able to test the electrolyser stack as well as balance the plant components under different operating conditions. It also includes advanced tools for monitoring key process parameters.

In the last five years alone, Tecnalia has participated in more than 80 hydrogen projects in different fields: production, distribution, transport, storage, use and safety. It is currently working on the design, development and operation of electrolyser prototypes for companies and has more than 70 researchers specialising in hydrogen-related projects.
