Local seasonal energy storage in the spotlight
In the transition to a sustainable and resilient energy system, local seasonal energy storage is a promising solution. The concept, which stores and deploys temporary surpluses of renewable energy when supply and demand are imbalanced, is essential for increasing security of supply and relieving the burden on energy infrastructure. This was emphasized in the study "Local Seasonal Energy Storage" by Royal HaskoningDHV to which Energy Storage NL contributed. Five key messages on local seasonal storage and living labs are central.
1. Local seasonal storage is crucial, but not yet prevalent
While applications such as thermal storage and processing of surpluses from solar and wind energy are well known, seasonal storage is still underutilized. Storing energy for months can reduce peak loads in the grid and offers opportunities for self-sufficiency in urban, rural and industrial areas.
2. Living labs answer technical, economic and social questions
Living labs are pivotal in researching and testing techniques for local seasonal storage. These practical situations provide valuable insights into performance and social impact. Social accountability and integrated system approaches are central to ensuring that future applications are widely supported.
3. Impact at the national and local level
Local seasonal storage not only contributes to decentralized self-sufficiency, but also has effects on national infrastructures. By applying local solutions at scale, national peak loads can be reduced and import dependence on energy is reduced.
4. Socially responsible innovation as a success factor
Citizens and businesses play a crucial role in the acceptance and implementation of energy storage. Living labs with a strong focus on participation and social added value create support and accelerate the energy transition.
5. Renewable generation surplus as a condition
Regional energy surpluses are a prerequisite for successful storage. By understanding local generation and storage capacities, regions can move in a targeted manner toward a 100% sustainable and future-proof energy system.
Future prospects and bottlenecks.
Although the potential is great, seasonal storage still faces economic and regulatory barriers. There is insufficient financial incentive from existing subsidies, and regulations hinder the optimal use of storage technologies. Innovative revenue models, coupled with more flexible market systems, are necessary to accelerate implementation.
With new living labs starting soon in urban, rural and industrial areas, the Netherlands is taking an important step towards a more sustainable energy system. Energy Storage NL remains committed to further developing the preconditions for successful local seasonal storage and putting the Netherlands on the map as a frontrunner in energy innovation.
