ZWIJNDRECHT, Belgium — Belgian partners DEME, Tractebel and Jan De Nul have released SEAVOLT, a new offshore floating photovoltaic (PV) technology.
This technology is a result of joint R&D, combining the expertise of solar, environmental and offshore experts. SEAVOLT can withstand harsh offshore conditions while creating large surfaces that are protected from the waves. The modular design allows for easy adaptation to different sites and demands. DEME said benefits include local renewable energy production and the possibility to install the panels in offshore wind farms (where local authorities permit multi-use concessions). Another advantage is the addition of large volumes of renewable energy capacity in a relatively short time.
The partners, together with Ghent University, started the VLAIO-funded research project MPVAQUA (Marine PV Aquaculture) within the frame of Blue Cluster four years ago. A marine floater concept was developed together with initial research on effects on the marine ecosystem, integration of aquaculture and a financial assessment.
Following laboratory testing, the partners are currently developing an offshore test installation, which will be launched off the Belgian coast in summer 2023.
Furthermore, in collaboration with RBINS, parallel tracks focusing on the ecosystem, the environment and cost effectiveness are being launched with the support of the Energy Transition Fund and the Federal Relaunch Fund.
The interest from the PV sector in offshore locations stems from land scarcity, combined with the need for local production and rapid acceleration of the energy transition. PV technology is developing faster than ever; The “magic” 1-TW milestone of installed capacity was reached in 2022, the need for local renewable energy production is increasing drastically, and the complementarity between wind and solar technology has been confirmed all over the world.
As authorities allow for multi-use concessions and the grid infrastructure shows good potential for combined use, the addition of offshore floating solar to current and future offshore wind sites presents an opportunity to add large volumes of additional renewable energy.
Tractebel CEO Philippe Van Troeye said, “In the same way that we have seen wind technology moving from land to the sea, we are seeing the extension of the whole energy system toward offshore locations. Along with offshore green fuel production, offshore energy islands, interconnectors and potential solutions for energy storage, we believe offshore floating PV has an important role to play in the acceleration of the energy transition."
