What is seasonal storage?

Seasonal storage is a form of storage technology that typically charges during over-production of electricity from renewable energy sources during summer and discharges in winter, when electricity demand is large and renewable electricity production, specifically solar PV, is low.

Can seasonal storage solve the problem of long periods without renewable generation?

Our research shows that seasonal storage provides a possible solution to address the problem of long periods without renewable generation, for example in the Northern European winter,” said Lucy Craig, Director of Technology and Innovation at DNV GL Energy.

Can seasonal storage decarbonize peak power generation?

Therefore, seasonal storage is a possible solution to decarbonize peak power generation when demand is high and variable renewable energy production is low and to make effective use of excess variable renewable energy when generation exceeds demand. The full report can be downloaded at

Is seasonal storage a viable balancing yearly cycles?

This is one of the key findings of DNV GL’s latest research paper ‘The promise of seasonal storage’, which explores the viability of balancing yearly cycles in electricity demand and renewable energy generation with long-term storage technology.

How do I maximize my battery storage system for cold weather?

The first step to maximizing your battery storage system for cold weather is to locate it in a place protected from the elements, such as a garage, house, or insulated building. Keeping the batteries in an insulated area ensures you maximize their performance, even if the temperatures outside are dropping.

Can synthetic fuels provide a stepping-stone for seasonal storage applications?

Rise of synthetic fuels can provide a critical stepping-stone for the use of seasonal storage applications. Overall need for additional storage solutions is lower than expected. Growing number of electric vehicles in our transport system will provide most of the needed energy storage solutions.
