According to the sunshine situation in Stockholm, this recommended scheme is:
February to October, the photovoltaic meets the daily electricity consumption, and the excess photovoltaic is used for hydrogen production; November to the following January, the stored hydrogen will feed hydrogen fuel cell power generation for power supply.
Based on the calculated results, the hydrogen production rate of the hydrogen production system is 4 Nm3/h, the total capacity of the hydrogen storage system is about 400 kg H2. ( about 5900kwh)
