About the IRTG
Why hydrogen?
The pressing significance of climate change and its associated risks to humanity are widely acknowledged, necessitating an urgent shift in our energy systems towards carbon neutrality. The substantial potential of renewable wind and solar energy must be utilized to achieve defossilization. However, widespread utilization of these intermittent sources requires effective means for transporting the energy over long distances and storing it for extended periods, for which hydrogen is very well suited. Hydrogen can be produced with good efficiency and offers remarkable versatility as a chemical energy carrier for various on-demand energy applications. It can be employed for electricity generation, providing heat for industrial processes and buildings, and as a fuel in transportation. On a global socio-economic scale, hydrogen production through processes like water electrolysis using renewable electricity or biomass gasification presents economic opportunities that can cater to diverse regions, each with its unique energy resources and needs.
Still, many challenges and open scientific questions exist in the hydrogen life cycle from production to utilization. For instance, hydrogen production by water electrolysis and its use in fuel cells require low-cost and stable catalysts with high activity; storage and transport of hydrogen are difficult because of its low volumetric density under non-extreme conditions; and hydrogen combustion can show intrinsic flame instabilities, which precludes its use in existing combustion devices. To address the existing challenges, fundamental research is needed addressing the scientific details in the research domains of hydrogen production, transport and storage, as well as its thermo- and electrochemical utilization while considering their interconnections.
Accordingly, this International Research Training Group (IRTG), covers these aspects holistically to pave the way for the widespread use of hydrogen as a renewable energy carrier with a meaningful impact on the wider community and society.
Aims and objectives of HyPotential
Responding to the pertinent challenges, the proposed IRTG aims to (1) advance the state of the research across the spectrum of hydrogen-based technologies including hydrogen production, transport and storage, thermochemical and electrochemical usage, and socio- and techno-economic analysis, and (2) train cohorts of excellent researchers and future leaders at different stages of their careers by providing them with holistic and interdisciplinary knowledge on a broad range of aspects related to the hydrogen life cycle that go beyond their immediate subject areas. RWTH Aachen University and Institute of Science Tokyo are jointly in a unique position to provide interdisciplinary competencies and an environment of world-class research both on the fundamental side, for instance, in electrocatalysis, membrane technology, combustion, and on the system scale for electrochemical, thermochemical, and other applications.
This IRTG is the first dedicated attempt in both Germany and Japan to train a young cohort of engineers, natural scientists, and social scientists uniquely qualifying them to drive national and international programs within the energy transition, for which hydrogen is increasingly considered a central element for a long-term strategy. Hydrogen, as the theme of this IRTG, is a global topic demanding regionally different solutions because of varying local conditions. Yet, worldwide interdependencies and globally connected solutions are essential and need to be fostered. Therefore, the exposure of all involved young researchers to two very different economies is a major added value provided by the IRTG.
