Can seasonal hydrogen storage increase solar PV Difusion in Sweden?

In conclusion, the idea of seasonal hydrogen storage for electricity might not be the ultimate path to increasing solar PV difusion in Sweden. However, the storage of energy in the more general sense in the form of hydrogen might very well be a driver that can facilitate an increase in solar PV capacity in Sweden.

How much peak power PV & storage capacity is needed in Sweden?

Figure 9: Estimation of installed peak power PV and storage capacity to enable 10 % of yearly electricity usage in Sweden to be covered. It can be seen from the results that 24 GWp peak power PV is needed as well as 3.46 TWh of electricity storage capacity.

How is PV capacity collected in Sweden?

All the grid-connected PV capacity is collected through surveys sent out by Statistics Sweden, SCB, (Statistiska Centralbyrån) on behalf of the Swedish Energy Agency (Energimyndigheten) to all the Swedish grid operators .

How much power does a PV system have in Sweden?

The official statistics provided by grid operators and collected by the Swedish Energy Agency only classify PV system sizes (power) into three ranges: 0–20 kW, 20–1000 kW, and >1000 kW. Table 7 summarises the total installations at the end of 2023 based on this data source.

How many energy storage facilities are there in Sweden?

The opening ceremony for one of the 14 facilities was held in Eskilstuna. The Role of Energy Storage in the Energy Transition Since 2023, Ingrid Capacity and BW ESS have been working together on 14 large-scale energy storage projects strategically located within Sweden’s electricity grid in price zones SE3 and SE4.

Does solar PV contribute to Sweden's energy supply?

Despite this potential, solar PV’s contribution to Sweden’s 508 TWh/yr energy supply is today minimal, accounting for only 0.2 % (1 TWh/yr) of the total energy supply . For Sweden to further tap into this vast supply of energy, some challenges are apparent.
