The envisioned role of hydrogen in the energy transition–or the concept of a hydrogen
economy–has varied through the years. In the past hydrogen was mainly considered a clean …

Research on 100% renewable energy systems is a relatively recent phenomenon. It was
initiated in the mid-1970s, catalyzed by skyrocketing oil prices. Since the mid-2000s, it has …

The role of hydrogen in a future energy system with a high share of variable renewable
energy sources (VRES) is regarded as crucial in order to balance fluctuations in electricity …

There are two competing concepts in the literature for the integration of high shares of
renewable energy: the coupling of electricity to other energy sectors, such as transport and …

The market for stationary battery storage systems (BSS) has been growing strongly around
the world for several years. The areas of application for BSS range from ancillary services, to …

Water electrolysis is a promising technology for storing surplus energy from intermittent
renewable energy sources in the form of hydrogen. The future investment costs of water …

The requirements made on energy system models have changed during the last few
decades. New challenges have arisen with the implementation of high shares of Renewable …

Pursued climate goals require reduced greenhouse gas emissions by substituting fossil
