Solar energy storage swedish policy

What is the goal of energy policy in Sweden?

The overall objective of energy policy is to create the conditions for efficient and sustainable energy use and a cost-effective Swedish energy supply with low negative impacts on health, the environment and climate and to facilitate the transition to an ecologically sustainable society (Bill. 2017/18: 228 direction of energy policy).

Can solar PV help Sweden achieve its climate goals?

If enabled by energy storage technologies, solar PV may become a helpful component for Sweden to achieve its climate goals. The mention of Sweden however is not because of its climate policy but rather for its geographical and environmental context making it an interesting topic for study when it comes to solar energy.

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.

Can seasonal storage improve the environmental benefits of solar PV in Sweden?

If seasonal storage can enable a larger dispersion of solar PVs in Sweden, the environmental benefits of it will also indirectly be those of solar PVs. In the case that it is, the benefits provided by hydrogen for this purpose may prove to be positive looking over the whole system. Unfortunately, there is a lack of studies investigating this.

Can seasonal energy storage be used in the Swedish energy mix?

Seasonal energy storage can be used to address the decrease in electricity production from solar PVs during the Swedish winter, which could eventually enable increased utilization of solar PVs in the Swedish energy mix.
