Designed for consistent performance in rough waters, the prototype marks a step forward in the pursuit of diverse offshore energy sources, particularly in regions already invested in wind energy infrastructure.
The Slow Mill system delivers more than clean energy. Functioning as an artificial reef, the structure contributes to marine biodiversity by providing habitats for sea life. Additionally, its ability to absorb wave energy could help mitigate coastal erosion, potentially reducing the frequency and cost of sand replenishment projects along vulnerable shorelines.
A key strategic advantage of the system lies in its compatibility with existing offshore wind installations. The technology is engineered to operate within the perimeters of wind farms, allowing it to utilize pre-existing subsea cabling and infrastructure. This co-location model optimizes energy transmission and reduces deployment costs, making the technology more commercially viable.
Plans are also underway to develop floating platforms for deeper-water deployment, which would significantly extend the range and scalability of the solution.
The current prototype produces up to 40 kilowatts of energy, enough to supply approximately 10 households. Building on this success, the next phase of development aims to scale output to 400 kilowatts through the installation of multiple units. Once implemented, this capacity could power up to 100 households, positioning the technology for entry into broader commercial markets.
Founded in 2012, Slow Mill Sustainable Power has focused on long-term research and development, with this successful demonstration serving as a validation of its efforts and opening pathways for investment and partnerships.
The project has received backing from several regional organizations, including InnovationQuarter and WaterFonds, under the Energy and Climate Program led by the Province of South Holland. This support underscores increasing institutional interest in wave energy as a complementary solution alongside wind and solar, particularly for countries with extensive coastlines.
