Project IPCEI Hy2Tech ES15

About the project

Sener is leading the IPCEI Hy2Tech ES15 project, a flagship initiative within the European hydrogen ecosystem. The project focuses on the development and industrial-scale deployment of next-generation electrolysers based on both advanced alkaline and AEM (Anion Exchange Membrane) technologies. Its primary goal is to transform conventional alkaline electrolysis into a new generation of systems that are significantly more efficient, compact, and fully aligned with the requirements of today’s energy landscape.

The initiative addresses the current technical and economic barriers of electrolysis through a combination of breakthrough technological innovation, advanced process automation, and manufacturing-oriented design. Key targets include lowering equipment costs by minimising the use of critical raw materials while dramatically enhancing both energy efficiency and operational flexibility of electrolysers. These improvements will enable seamless integration with renewable energy sources and smooth deployment in complex industrial settings.

The project forms part of the broader IPCEI Hy2Tech framework (Important Project of Common European Interest in Hydrogen Technology), a set of high-priority actions with a strong R&D focus and a clear mission to decarbonise strategic industry sectors. Within this programme, Sener leverages its proven technological expertise and advanced engineering capabilities to deliver solutions that make green hydrogen production more efficient, cost-effective, and readily scalable.
