Producing green hydrogen thanks to wave movement

Taking a look back at the success stories of 2022, the Luxembourg Institute of Science and Technology developed a proprietary technology providing freedom from the intermittent nature of variable renewable energy, such as solar and wind power, but from ocean’s waves as a source of electricity in the water electrolysis process.

The principle of electricity production by a chaotic trajectory pendulum system was validated and proved in the environment of the wave pool of the Thermes de Strassen. These results made it possible to validate a first level of performance of a 1/6th scale technological demonstrator incorporating an electrolyser for the in situ production of hydrogen. The system at scale 1 will aim for autonomous operation in a marine environment.

This proof of concept has strong economic potential with regard to hydrogen production costs, while minimising the strategic dependence on critical metals and scarce land resources used in variable renewable energy.

This device was exhibited to local industrial stakeholders at the TechDay at the Maison des Arts et des Etudiants in Belval on 15 June 2022. It aims to convince local players of the robustness of the technology in order to move towards the next stage of a full-scale demonstrator in the marine environment. A recent visit by politic players has already enabled us to discuss the potential of this technology "made in LIST".
