PRESS RELEASE: ALAZ ARIMA AND NORDEX ELECTROLYZERS S.L. JOIN FORCES FOR PROJECT “RECAFEL”

Alaz Arima and Nordex Electrolyzers, a company supported by “Sodena, a public company of the Government of Navarra,” have joined forces to develop Recafel, a project aimed at improving the efficiency of hydrogen electrolyzers and reducing energy consumption for H2 generation. This collaboration aims to advance cooling solutions for electrolyzers using innovative technology, through devices called thermosiphons. This technology allows for heat transfer through the evaporation and condensation of a fluid. It is more efficient and reliable than traditional cooling methods, such as water recirculation circuits. This innovative phase change technology makes Alaz Arima and Nordex Electrolyzers leaders in the field of energy transition.

Luis Solla, CEO of Nordex Electrolyzers, emphasizes the importance of this technology: “Thermosiphons are systems that are simple in appearance but of great technical complexity. The application of this technology will allow us to make a qualitative leap in the cooling of electrolyzers. This will not only help us optimize technical performance, but also significantly reduce operating costs.”

Nordex Electrolyzers, specialized in the design, manufacture, and assembly of pressurized alkaline electrolyzers, considers this collaboration an essential step to differentiate itself in an increasingly competitive market. Thermosiphons will not only improve the technical performance of electrolyzers but will also help consolidate Nordex Electrolyzers in the sector as one of the most innovative players.

An innovation driven by European funds

The Recafel project has received funding of €243,250, thanks to the support of the Government of Navarra and the European Regional Development Fund. This financial support will allow Alaz Arima and Nordex Electrolyzers to carry out the necessary research and testing to validate the developed technology and move towards its commercial implementation.

“The hydrogen sector is expanding, and Recafel offers us the opportunity to lead a necessary change to make renewable hydrogen production more efficient and sustainable,” says Solla. “We are facing a unique opportunity to generate disruptive technology that will not only benefit our companies, but the entire energy industry,” he adds.

With Recafel, Alaz Arima and Nordex Electrolyzers face a technological challenge that could set a new standard in electrolyzer cooling, opening the door to new industrial applications and greater competitiveness in the green hydrogen sector.

About Nordex Electrolyzers

Nordex Electrolyzers designs, manufactures, and installs pressurized alkaline electrolyzers to produce green hydrogen. With headquarters in Navarra and Puertollano in Spain, and a highly specialized team, it has developed prototypes of 50kW and 500kW. Currently, it is focused on the development of a 2.5MW prototype.

Nordex Electrolyzers seeks to contribute to a sustainable future through the transition to green energy. Nordex Electrolyzers is a joint venture founded in 2022 between Sodena, a public company of the Government of Navarre, and Nordex Group.

About ALAZ ARIMA

ALAZ ARIMA develops high-performance cooling solutions mainly applicable to the Renewable Energy and Electric Mobility sectors. Through devices called thermosiphons, heat is extracted by changing the phase of a fluid, without the need for recirculation pumps. These are passive cooling solutions, with no electrical consumption and no maintenance required, providing high reliability and long lifespan. Currently, they market equipment for cooling photovoltaic inverter IGBTs and traction boxes, among others.

Based in Pamplona, ALAZ ARIMA has facilities equipped to validate their developments under the most unfavourable operating conditions.
