GOWES
Grid Connected Offshore Wind + Energy Storage
Publieke samenvatting / Public summary
Aanleiding
Supply and demand on the electricity grid always needs to be in perfect balance with each other. Therefore, as the amount of variable renewable energy sources (wind and solar) increases, so too does the need for more flexibility on the demand side of the energy system. There are several ways to increase the flexibility on the demand side. Energy storage (and power to X) are options for this. In addition to this fundamental need for more flexibility, offshore wind farms are evolving into so called hybrid power plants when offshore wind is being combined with floating solar assets and electrolysers for hydrogen production. How these assets should be sized and operated to provide a healthy business case for the operator is currently unknown and storage could play a critical role in such a hybrid power plant.
Doelstelling
This project GOWES therefore will study how storage could be combined with two Dutch upcoming wind farms Ten Noorden van de Waddeneilanden (TNW) (0.7GW) and Doordewind, site I (2GW). Specifically, the following questions will be answered. • How can offshore energy storage support the flexibility requirements of The Netherlands? • What value can this add to offshore wind projects: unlock new revenue streams? enable new business models? • What cost targets must be achieved (€/kWh) on the two technologies selected, providing different time ranges for flexibility?
Korte omschrijving
The project partners are Seaway7, a global leader in offshore project delivery, with a growing interest and development portfolio of offshore hydrogen and offshore energy storage. TNO is the independent research organization who will be using its state-of-the-art models to model the scenarios to answer the above questions. GROW is a joint research program with much of the Dutch wind sector industry actively involved as partners. GROW makes a financial contribution to this project and GROW wind farm developers will give feedback during the project's performance.
