The 'Unite!Energy' research program focuses on advancing hydrogen as a sustainable energy storage medium to address the challenge of mismatched demand and production of renewable energies. By utilizing green hydrogen produced through electrolysis powered by renewables, the program aims to store and distribute energy efficiently. Through international collaboration, doctoral students are investigating hydrogen's role in storing surplus electrical energy and power generation during peak load times. Research areas include water electrolysis, fuel cell catalysts, and hydrogen storage concepts. The program involves partnerships with industry and universities, aiming to prepare a new generation of innovative researchers in the energy field. 'Unite!Energy' strengthens the research field of Energy and Environment at TU Darmstadt and complements research projects focusing on hydrogen technology to facilitate the climate transition.
