Ansaldo Green Tech successfully tests its first full-size AEM electrolyzer prototype
Ansaldo Green Tech, a part of the Ansaldo Energia Group, has reached an important milestone in the framework of its development program for anion exchange membrane (AEM) electrolyzers by successfully concluding tests on short stack prototypes of full-size geometry, which will lead to a commercial stack of 1 MW.
The prototypes, whose electrochemical cells have an active area equal to several thousand square centimeters, were operated until full power was achieved, exceeding expectations in terms of current density and efficiency.
This result is a part of the Nemesi project, supported by PNRR funds, and was successfully achieved thanks to the know-how and experience of the Ansaldo Energia Group in the fields of hydrogen and fuel cells.
The program foresees, in the short term, the completion of the test facility to continue the performance verification phase. This will allow progression towards the goal of product industrialization and commercialization. In parallel, research and development activities continue at the Ansaldo Green Tech laboratories and the University of Genoa (a partner in the Nemesi project), aiming to improve the performance of electrodes and membranes.
The AEM electrolyser is characterized by reduced use of critical raw materials and electrolytes, high flexibility (making it suitable to follow the cyclicality of renewable sources), and by the possibility of producing hydrogen under pressure. The product integrates synergistically with other activities of the Ansaldo Energia Group aimed at supporting the decarbonization process.
