This study investigates how green hydrogen through the utilisation of CAES can contribute to securing a sustainable level of bioenergy use in the Danish electricity sector by substituting the biomass-based dispatchable electricity-producing units with a dispatchable electricity-producing unit consisting of a CAES unit fueled by green hydrogen.
This is investigated by utilising knowledge and theories about the dependency on bioenergy and the lock-in mechanisms that hinder the implementation of alternative sources of energy. Furthermore, an energy system analysis is applied for the investigation of the hydrogen-CAES system. This is used to investigate the amount of electricity the system can contribute with and thus the amount of bioenergy that can potentially be substituted and the revenue that can be obtained by operating the system.
The simulation results show that the Green Hydrogen Hub can produce 1.04 TWh of electricity annually, based on the used assumptions. It can be argued that this electricity, or parts of it, can be used to substitute bioenergy used for electricity production and thus minimise the bioenergy dependency.
