On 12–13 June, the X-SEED consortium met once again — this time in Barcelona, hosted by Leitat Technological Center. This in-person gathering marked a new milestone for the project, providing an important space to review progress, strengthen coordination, and align on both strategic and technical priorities.
Two Days of Collaboration and Progress
The agenda featured working sessions focused on key aspects of the project, ranging from management and coordination to critical technical developments such as the design of the membrane-less supercritical cell, catalyst and electrode optimisation, and test bench preparation.
The first day began with an institutional welcome, followed by progress meetings, partner updates, and joint planning to ensure alignment across all work packages. In the evening, consortium members shared a group dinner in the city — an ideal moment to strengthen connections and reinforce the human dimension of collaboration.
The second day continued with practical technical exchanges, discussions around system testing, shared challenges, and strategies to maintain momentum and deliver on the project’s objectives.
A Shared Commitment to Clean Hydrogen
What stood out most during the meeting was the sense of energy, purpose, and commitment across the consortium. Beyond coordinating tasks and reviewing data, the partners used the opportunity to reflect on achievements to date, identify areas for improvement, and maximise the impact of X-SEED within the European hydrogen landscape.
With renewed motivation, the team leaves Barcelona more connected and more determined than ever to keep advancing cutting-edge hydrogen technologies — together.
About the project
The main objective of X-SEED is to make renewable hydrogen more affordable. The key innovation is the development of a membrane-less electrolyzer that operates in supercritical water conditions—above 374°C and 220 bar. This approach produces high-quality hydrogen, improving energy efficiency, sustainability, and system longevity.
With a duration of three and a half years, the X-SEED project is coordinated by Technological Centre Leitat, also involves SNAM, Industrie De Nora, Particular Materials and DTU.
X-SEED project is co-funded by the European Union and supported by Clean Hydrogen Partnership and its members with a total budget of €2,989,495.
X-SEED goes beyond technology by driving the hydrogen ecosystem, helping Europe achieve climate goals and boost its leadership in energy transition and technological innovation
