Abstract:
Power Systems with a high share of variable renewable energy (VRE), e.g., the European Union, must face several challenges related to curtailment, flexibility, and system stability. Therefore, the development of new technologies for the decarbonization of the electricity network and the future models of power systems should consider these challenges. In this study, we propose renewable hydrogen, a decarbonized fuel, as an energy carrier (chemical energy storage). In addition, a new model (in development) to facilitate the integration of VRE's generation into the power system according to the climate change objectives is outlined. Hydrogen is a versatile and clean energy carrier because its combustion does not produce emissions. Electrolysis to produce hydrogen is a commercial option to study the coupling with the surplus of VRE's avoiding or minimizing curtailment. However, hydrogen can also be produced from biomass at a large scale. Large scale and long-term underground storage can be done in salt caverns. Furthermore, hydrogen-rich fuels could be used in solid fuel cells (SOFC) to generate electricity. The preliminary results indicate that these options would provide a reliable and flexible electricity generation, as well as stability to the system.
