Floating solar plants
Large-scale floating photovoltaics plants can be one of the solutions for a sustainable energy supply. The EU has now approved a project that will optimise the anchoring and mooring of floating solar plants and adapt the anchoring to ocean environment as well. The aim is to significantly reduce the cost of anchoring floating solar parks.
RISE is part of a consortium of Swedish, Spanish and Portuguese players who have now received funding from the European Union's European Maritime and Fishery Fund (EMFF) to develop the technology for anchoring and mooring floating solar cells. The FRESHER project (Floating Solar Energy mooring: Innovative mooring solutions for floating solar energy) will start this month and continue for two years.
"We are happy to be part of the value chain in such an innovative and emerging market, providing competences to the industry and supporting SME’s," said John Rune Nielsen, Director Research and Innovation at RISE.
The main goal of the FRESHER project is to be able to showcase and validate new innovative anchoring technology for floating solar power plants. The new technology results in both greatly improved LCoE (Levelised Costs of Energy) and increased capacity for solar power. The solar power should therefore cost less and provide more energy, which makes it possible to increase the rate of expansion so that ocean based solar parks can be profitable.
The project leader is Seaflex, a company that offers flexible and environmentally friendly anchoring and mooring solutions:
"Seaflex has worked in the marine industry for a long time, focusing on the environmental aspect of safe and efficient mooring systems. The development in this project is aimed directly at floating solar cells and is therefore very important to us," said Lars Brandt, CEO at Seaflex.
Another partner in the project is EDP, a Portuguese energy company with an energy production target of 70% renewable sources by 2022, and which already has an active floating solar cell park in northern Portugal. They see a great future for floating solar cells.
"Portugal has the ambition to be carbon neutral by 2050 and to have 80% of the energy supplied by renewable sources (RES), a commitment that EDP shared from the first day. Hybridising alternative sources of energy with our hydro fleet is one of the fastest ways to help accomplish this target," said João Maciel, Director for EDP CNET.
"Floating photovoltaic, only in Portugal, has a potential of more than 2 GW. However, the harsh environment in our dams and competition with other conventional RES technologies requires an optimisation of the mooring designs and a reduction of costs . Our ambition goes in three ways: improve the existing solutions, bring competitive proposals and contribute for the design in harsher environments, as the offshore sea water applications," Maciel continued.
FRESHER's goal is thus to show that floating solar energy is ready to take the next step and grow in market share. Among the new technologies in the project are so-called PV anchoring suitable for the marine environment, which open up new markets and uses in the green energy transition. The design is based on lessons learned from previous tests and commercial implementations as well as experience from the industrial and offshore sectors.
Other partners in the FRESHER project include Portuguese marine renewable energy firm WavEC and Spain's ISIGENERE, which specialises in floating photovoltaic technology.
António Sarmento, President of the Board of Directors at Wavec commented: “WavEC is delightful to join the effort to design and demonstrate at full-scale an innovative mooring solution to take a step forward in improving the performance of floating solar power plants, easing its manufacturability and deployment and eventually LCoE reduction. In addition, it is noteworthy the contribution of the Fresher project to the business development of this emergent sector and in advancing the maturity of its value-chain.”
Emilio Pons Puig, Engineering and Development Director at Isigenere said: “We are very excited to participate in this EU project which will bring new insight and competitiveness in mooring applications to floating solar installations.”
