HGF Innovation Pool Project "Solar Hydrogen - Highly Pure and Compressed"

Erlangen, April 27, 2023 - The Helmholtz Innovation Pool project "Highly pure and compressed solar hydrogen" aims to provide essential scientific knowledge and viable technologies for the conversion of solar energy into hydrogen with the highest possible value for a sustainable energy system. Researchers from the participating Helmholtz centers met for this purpose at HI ERN to share their latest results.

The sun, as one of the most powerful natural energy sources, provides free and abundant energy that can be captured and converted into hydrogen (also called solar hydrogen) through various technological routes. To achieve its highest possible value as a fuel for power generation and the mobility sector, and as a raw material with broad industrial applications, hydrogen must meet strict criteria in terms of its purity and pressure.

The technologies pursued in the Innovation Pool project, which are the subject of the recently published review article, enable the production of solar hydrogen with the highest purity and pressures that in some cases far exceed atmospheric pressure.

More than 20 scientists from the Helmholtz centers involved in the Innovation Pool project gathered at HI ERN's Erlangen headquarters to share their latest findings on new technological pathways for solar hydrogen production and storage.

In addition to HI ERN, as a branch of Forschungszentrum Jülich, the Karlsruhe Institute of Technology, the Helmholtz Centers Berlin and Dresden-Rossendorf, the Max Planck Institute for Plasma Physics, the German Aerospace Center and Forschungszentrum Jülich are contributing their respective expertise to the innovation pool project. In particular, HI ERN contributes theory and simulation to manufacturing and operating processes of novel electrolyzers.
