RWE and the Dutch-Norwegian company SolarDuck signed a collaboration agreement to develop the use of floating solar parks at sea, according to RWE's release. To accelerate the learnings on SolarDuck’s floating solar technology, RWE will invest in a first offshore pilot in the North Sea. The project is a first step in the collaboration and lays the foundation for a larger demonstration project at the Dutch offshore wind farm Hollandse Kust West (HKW). RWE is tendering for this project, and has included SolarDuck into its bid with a highly innovative combination of offshore floating solar with integrated storage solutions.
The offshore floating solar technology, as developed by SolarDuck, establishes a new frontier for solar energy and provides an answer to increasing land scarcity for the generation of renewable energy. The integration of offshore floating solar into an offshore wind farm is a more efficient use of ocean space for energy generation (using the space between the wind turbines) and allows for synergies with regards to the construction and maintenance of the multi-source renewable energy plant. The result is a more balanced production profile due to the complementary nature of wind and solar resources.
SolarDuck´s unique, triangular-shaped platform, which has received the world´s first certification for offshore floating solar by Bureau Veritas, is designed to float several meters above the water, following the waves like a carpet. Therefore, keeping critical electrical components dry, clean and stable, as well as securing the integrity of the semi-submersible structure while enabling safe operations and minimal maintenance.
To accelerate the development of the technology, RWE will invest in SolarDuck’s full-scale offshore pilot called ‘Merganser’ with a nameplate capacity of 0.5 MWp in 2023. ‘Merganser’ is expected to be installed off the coast of Ostend in the Belgian North Sea and will be SolarDuck’s first offshore pilot following the successful deployment of an inland pilot in the Netherlands last year. ‘Merganser’ will provide RWE and SolarDuck with important first-hand experience in one of the most challenging offshore environments in the world. These learnings will enable a faster commercialisation of the technology from 2023 onwards.
RWE is a leading global player in renewable energy and number 2 worldwide in offshore wind. The company currently has 18 offshore wind farms in operation; it is constructing the Sofia (1.4 GW off the UK coast) and Kaskasi (342 MW off the German coast) wind farms, and has a total of more than 10 GW of offshore wind farms under development. For many years, RWE has been a partner of the Dutch government to advance the energy transition by investing in clean energy solutions. RWE currently operates seven onshore wind farms in the Netherlands with a total installed capacity of over 330 MW (RWE's pro-rata share), with new ones under development and construction as well as solar farms including the floating PV project in Amer. RWE is also working on the expansion of CO2-free flexible production capacity and the development of onshore and offshore hydrogen projects, such as H2opZee, NortH2 and FUREC to help industry reduce CO2.
SolarDuck is a Dutch-Norwegian OFPV company with strong roots from the maritime industry. The company was established following a spin-off from Damen Shipyards (the largest shipbuilder in the Netherlands).
