The aim of this report was to examine the viability and identify possible benefits of implementing a PV and hydrogen storage system in Skolfastigheter AB’s facilities in Uppsala. The idea is that surplus solar energy from the school’s PV system is directed towards hydrogen gas production. By storing the produced hydrogen gas, it can supply the school with electricity in times of low solar radiation, such as during the winter. The study was conducted using data from Tiundaskolan in Uppsala. Three models were designed, investigating the number of self-sufficient days from utilizing the hydrogen gas, considering factors such as installed PV capacity and total yearly electrical energy consumption. All models were based on data from Tiundaskolan. Model A showcases the implementation of a PV and hydrogen storage system at Tiundaskolan specifically, while Model B takes varying electrical energy consumptions into consideration. Model C dimensions a school’s energy system to enhance the number of self-sufficient days, and thereby increases the favorability of the implementation of hydrogen storage. The results show that considering current conditions, Tiundaskolan would only be self-sufficient on hydrogen for almost 3 days, and the number of days increases significantly when more PV capacity is installed. Additionally, the dimensioning proposed in Model C further enhances the impact of installing more PV capacity. The conclusion was drawn that implementation of this type of system can be viable for Skolfastighter AB, if the safety aspects of hydrogen gas are taken into consideration. The conditions for successfully utilizing hydrogen storage include the size of the PV system, the total yearly energy consumption, and features such as the rooftop design and the school’s location. Identified benefits of using hydrogen storage include the ability to balance the electrical grid and reduce capacity deficiency, contributing to the technological development of hydrogen gas and being at the forefront of the green transition. Furthermore, the ability to stay self-sufficient through hydrogen storage could be crucial for a school in the event of a crisis or power shortage since it can contribute with security to the local society. |
