Rijkswaterstaat has renovated the Flakkeese Spuisluis and put it back into use in 2017. After the renovation, a two-way connection was created. The water can flow from the Oosterschelde to the Grevelingenmeer and vice versa. This improves the water quality of the Grevelingenmeer and creates a place to produce tidal energy.
A consortium, including project developer BT Projects, wants to take advantage of this opportunity and realize a test and demonstration center for tidal energy, the Tidal Technology Center Grevelingendam. The ultimate goal is to develop an (inter) nationally applicable tidal energy system.
What makes tidal energy complex is the shared ownership when using objects, such as locks. That is why it is important to develop knowledge from a shared vision and a shared interest. The question of BT Projects was therefore: what interests do we have to take into account in order to smoothly go through the licensing process and what knowledge is required for this? Together with Delta Platform, BT Projects is raising this demand more broadly. Stakeholders in the area, together with researchers and other experts, map out the effects, interests and possible combinations. Together they work on knowledge questions that arise. The focus is on tidal energy, the starting point is the Flakkeese Spuisluis location.
The process resulted in several subprojects, including in the field of asset management. A Raak Pro application was accepted in early 2017 for the sub-project ‘Playing with Currents’. In this project, partners work together on the question: How to build a tidal power station in an ultra-low decay site, aimed at maximum economic profit and with minimal impact on ecology.
The Play with Current project (2017-2021) has resulted from this. Jacob van Berkel is actively involved in this project as a lecturer in Delta Power. Annelies Koomans van den Dries is the first point of contact.
Playing with Strooming is a project where “playing with currents” is central. Research is being conducted into 1) improving water quality, 2) generating energy, not only focusing on the possibilities of a passage. The project is in transition from Phase 1 to Phase 2.
