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.
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.
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.
Fereidooni et al. (2018) studied the economic feasibility and annual performance of a 20 kW photovoltaic power station located in Yazd City, Iran, and found, through both experimental studies and simulations, that the region is capable of generating electricity for hydrogen production [ 10 ].
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.
Comparing the results for the power storage in all scenarios reveals that the increased capacity of the storage installation in the systems in scenarios S1 and S2 contributes to the increased power storage in the form of hydrogen.
