Floating Solar Panels That Survive Ocean Waves for Coastal Energy

energyPilotedTRL 7

Imagine laying solar panels on the ocean surface the way fish farms float their pens in rough Norwegian waters. That's exactly what this project did — they built an ultra-thin membrane (thinner than a credit card) that sits on water and holds solar panels, flexing with the waves instead of fighting them. Regular floating solar only works on calm lakes, but this system handles open-sea wind and waves thanks to 20 years of know-how borrowed from the aquaculture industry. The result is a way to generate solar power without using any land at all.

The business problem

What needed solving

Coastal cities and island nations desperately need solar energy but have no land to spare. Conventional floating solar panels work fine on calm lakes and reservoirs, but ocean waves and wind destroy them within months. Until now, there has been no commercially proven way to deploy large-scale solar on open sea waters.

The solution

What was built

A full-scale floating solar prototype using a patented hydro-elastic membrane (less than 1mm thick) attached to buoyant tubing, designed for open-sea deployment. The mooring and anchoring system was adapted from 20 years of Norwegian fish farming technology to handle rough wave and wind conditions.

Business applications

Who can put this to work

Offshore Energy Development
enterprise
Target: Offshore wind or marine energy developers looking to add solar capacity

If you are an offshore energy developer dealing with expensive subsea infrastructure that sits idle between wind turbines — this project developed a floating solar system proven in open-sea conditions that can share your existing mooring and grid connections. The consortium expects 1,750 MW of installed capacity within 5 years, representing 6.2% of the addressable market.

Coastal Utilities & Island Power
mid-size
Target: Electric utilities serving coastal cities or island communities with limited land

If you are a utility company serving a coastal or island population and struggling to find land for solar farms — this project built a full-scale floating solar prototype designed for non-sheltered sea waters. Each plant lasts at least 25 years, and the technology avoids CO2 emissions of 4,120 kt over the initial deployment phase.

Aquaculture & Fish Farming
SME
Target: Fish farming companies with existing offshore infrastructure

If you are a fish farming operator with floating pens and mooring systems already in the water — this project's technology was directly inspired by your industry's 20-year track record in rough Norwegian seas. You could co-locate floating solar with your existing operations, generating on-site power and reducing diesel dependency for offshore operations.

Frequently asked

Quick answers

What does the system cost compared to land-based solar?

The project objective mentions reducing LCOE (Levelized Cost of Energy), Capex, and Opex as key targets, but does not publish specific cost-per-watt figures. Based on available project data, the consortium projects accumulated profits above €94m from the expected 1,750 MW deployment, suggesting commercial viability at scale.

Can this scale to utility-grade installations?

Yes. The project built and tested a full-scale prototype ready for large-scale testing. The consortium's 5-year target is 1,750 MW of installed capacity, which represents 6.2% of their serviceable addressable market. Each installation is designed to last at least 25 years.

Is the technology patented? How can I license it?

Yes, the core floating hydro-elastic membrane technology is patented. The coordinator, Ocean Sun AS, is a Norwegian SME that owns this intellectual property. Licensing or partnership discussions would need to go through Ocean Sun directly.

How does this handle storms and rough seas?

The system uses a hydro-elastic membrane thinner than 1mm attached to buoyant tubing. It moves with the waves rather than resisting them — similar to how oil calms troubled water. The mooring and anchoring design draws on over 20 years of proven fish farming technology used in rough Norwegian waters.

What's the environmental impact?

The consortium estimates the initial deployment would avoid 4,120 kt of CO2 emissions. Since each plant lasts at least 25 years, the long-term impact is projected at 5 times that figure. The system leaves no permanent footprint on the seabed beyond mooring anchors.

How soon can this be deployed commercially?

The project ran from 2021 to 2023 and is now closed. A full-scale prototype was constructed and installed for large-scale testing. Ocean Sun AS, the coordinator, is actively bringing the technology to market. Based on available project data, commercial deployments should be underway or imminent.

What support is available for integration?

The consortium includes 6 partners across Norway, Spain, and France, with 4 industrial partners providing expertise in mooring, marine operations, and solar technology. Ocean Sun AS has direct experience deploying systems in Norwegian sea conditions and can support engineering and installation.

Consortium

Who built it

The BOOST consortium is lean and commercially focused: 6 partners across Norway, Spain, and France, with 4 out of 6 being industry players (67% industry ratio) and zero universities or research institutes. This is unusual for EU projects and signals a team built for market delivery, not academic publishing. The coordinator, Ocean Sun AS, is a Norwegian SME — the patent holder and technology originator. The geographic spread covers Northern Europe (harsh sea testing conditions) and Southern Europe (high solar irradiance markets), which is a smart combination for proving the technology works where it's hardest and sells where it's most profitable.
