Hydrogen as a foundation of the energy transition. Pt. 2: Sector coupling and hydrogen. Two sides of the same coin

This second part - Sector coupling and hydrogen: two sides of the same coin - takes up this point. It deals in detail with possible utilisation paths of hydrogen in the transport, industry and heat sectors, as well as with the systemically important aspect of reconversion to electricity. Using current research work at DLR as an example, it illustrates the potentials that arise from coupling the various energy consumption sectors in the production and use of hydrogen. These synergies pave the way for a more efficient and flexible use of renewable energy. In addition to the technological application possibilities, the infrastructure and associated safety aspects also play an important role in the use of hydrogen. Furthermore, DLR is conducting research in the field of energy system analysis to assess the impact of large-scale hydrogen infrastructures on the existing and future energy system. This also includes the questions of whether a climate-neutral energy system is at all conceivable without hydrogen from today's perspective, or how large the hydrogen demand and supply would be in such target scenarios. In addition, environmental impacts are being investigated and life cycle analyses are being prepared.
