This study focused on the modelling and optimization of hydrogen storage integrated with combined heat and power plants and rooftop photovoltaic systems in an energy system in central Sweden. Three different scenarios (S0–S2) were designed to investigate the impacts on the system flexibility and operational strategy.
The regional energy system including the CHP plants and heat-only boilers integrated with rooftop PV systems and power-to-gas storage is considered as the reference scenario. The other scenarios are described to investigate the potential of the hydrogen storage and the fuel cell application to meet the deficit of power supply in the system.
Many studies have been carried out to investigate the effect of hydrogen storage on a power system based on renewable resources, especially wind power. The potential of hydrogen for providing a long-term storage in different system architectures was evaluated by Lewandowska-Bernat et al. .
The results indicate that the proposed storage system increases the system flexibility and can reduce power imports and the marginal emissions by around 53%, compared with the current energy system. There is a potential to convert a large amount of excess power to hydrogen and store it in the system.
Almost all of the stored hydrogen is from the conversion of excess power produced by the PV system. The maximum power import to the region in scenario S0 is 322 MW. The system supplies excess power over the studied period, which can be converted to hydrogen using an electrolyser and stored into the hydrogen tank.
This paper proposes an optimal planning model for the hydrogen-based integrated energy system (HIES) considering power to heat and hydrogen (P2HH) and seasonal hydrogen storage (SHS) to take full advantage of multienergy complementarity.
