Elogen said its membrane electrolysis technology has been selected by Storengy as part of the project, developed by the Communauté d'Agglomération Pau Béarn Pyrénées, for the operation of the Lescar wastewater treatment plant, and the construction of methanization and methanation units.

Elogen will design and produce a PEM electrolyzer with a power of 1 MW, and capable of peak operation at 1.3 MW. The Elogen electrolyzer, which will be part of the methanation unit, will be delivered in the first half of 2023 to the Lescar wastewater treatment site.

The PEM electrolyzer, designed by Elogen, will be used in the production of synthetic methane developed by Storengy in Pau Lescar by means of an innovative technological process of catalytic methanation. This process will make it possible to transform all the carbon dioxide emitted by the methanization unit present on the site, into synthetic methane, thanks to the use of the hydrogen produced by the electrolyzer.

The project, developed by Pau Béarn Pyrénées, will make it possible to produce 10 energies and resources from the wastewater of Lescar1, and is part of the objective to achieve carbon neutrality by 2040.

"We are particularly proud of this new contract as it allows Elogen to contribute to the development of an unprecedented project to transform a depollution unit into a real "biofactory" that will produce green energy and resources from wastewater and CO2," said Jean-Baptiste Choimet, CEO of Elogen. "This is also a third collaboration with the Storengy group, the second in the field of methanation, confirming that the PEM technology developed by Elogen offers the advantages sought for the most innovative projects."

"With ever more innovative solutions for the production of renewable and low-carbon gas, Storengy enables its customers to accelerate their energy transition," said Christophe Renier, Director of Industrial Expertise and Energy Solutions at Storengy. "Thanks to the hydrogen produced by the Elogen electrolyzer, our methanation process will transform all the CO2 resulting from the treatment of sludge from the sewage treatment company in Lescar into synthetic methane, which is 100% renewable. This will be a first in France. We are proud to be able to write this new story as part of our consortium with Suez and all of our partners, on behalf of the Communauté d'Agglomération Pau Béarn Pyrénées."
