Energy storage knowledge center

Energy Storage NL is the subject matter expert on energy storage and conversion technology. We promote awareness and knowledge about the current and future role for energy storage and conversion in the energy system. We have collected our knowledge documents in one place, visit our Knowledge base to see these.

We gather information from the national and international market and offer it in a useful way to our participants and other stakeholders.

This do we by

Initiate and encourage

Initiate and stimulate projects and studies on innovative technologies, applications, markets and business models for energy storage and conversion. Together with research firms, we commissioned studies on, among other things, the costs and benefits of battery storage in the electricity system and together with our participants, we have made the Plan of Approach Heat Storage prepared and presented to the Ministry of Economic Affairs.

External projects

We regularly collaborate with stakeholders on projects to promote energy storage. For example, we contribute to studies commissioned by universities, governments and grid operators, among others. Examples include the model agreement Cable Pooling with storage and the Smart Storage Trend Report

Working Groups

Establish and maintain working and project groups in which participants can learn from each other's experience and expertise.
There are currently six working groups active within Energy Storage NL, namely:
1- Electricity Storage
2- Market Information
3- Safety
4- Heat Storage
5- Molecule Storage
6- Sounding Board Policy

Here our participants work on knowledge development and exchange on these topics.
