30kWh mobile energy storage container used at Nordic airports

How much battery capacity will the Nordic countries have by 2030?

The Nordic countries are expected to have almost 1800 MW of installed battery capacity by 2030, not including batteries in electric vehicles. Figure 06.3: Expected battery capacity in the Nordics by 2030, not including batteries in electric vehicles.

Which countries have a large energy storage capacity?

Finland, Norway and Sweden have a substantial energy storage capacity of approximately 125 TWh, thanks to their large hydro reservoirs. To put the Nordic hydro storages into perspective, the energy storage capacity of 100 million electric cars is approximately 5 TWh (assuming 50 kWh per car).

Why do we need hydro reservoirs in the Nordic region?

The Nordic region benefits from large hydro reservoirs that provide excellent and cost-effective energy storage options, which are already being efficiently utilised. Meeting growing future flexibility needs with a changing energy mix will require supplementing hydro reservoirs with batteries or hydrogen-based fuels.

What is the largest underground thermal energy storage in the world?

Vantaa Energy in Finland started the construction of the largest underground thermal energy storage in the world. It will have a volume of 1.1 million m3 and capacity of 90 GWh, approximately 5% of Vantaa's annual DH demand.
