New combined solution to harness wave energy full renewable potential for sustainable electricity and fresh water production

Periodic Reporting for period 3 - W2EW (New combined solution to harness wave energy full renewable potential for sustainable electricity and fresh water production)

Reporting period: 2021-12-01 to 2022-10-31

With 96.5% of all water on Earth being on the ocean, there is a theoretical ocean wave energy potential, which could contribute to decarbonizing the energy system and at the same time expand the water supply through desalination, creating a new industry with export opportunities worldwide.

This project consists of the implementation of an innovative integration of wave energy and water desalination technologies, to produce zero-emission electricity and fresh water.

The project consortium consists of Vryhof Anchor (Mooring), Wavepiston (Wave Energy), Fiellberg (Hydraulics and Desalination) and Ener.Med. (Grid, Monitoring and Control). Together we assemble the multidisciplinary technologies needed to demonstrate the benefits of a combined system of using wave power for electricity conversion and desalination, and to get the Wave to Energy and Water (W2EW) solution commercialized.

The consortium plans to roll out the W2EW solution at off-grid, small-scale energy and water production sites in islands and isolated coastal communities with up to 100,000 inhabitants, which corresponds to a potential market of 22Bn EUR for electricity and 6Bn EUR for freshwater.
The main goal of this project is to integrate the partners’ technologies, demonstrate the combined solution, and build the market to pave the way for broad market roll-out.

In collaboration with the local community and the local authorities a full-scale Wavepiston wave energy converter will be installed in PLOCAN, Gran Canaria.The wave energy converter leads pressurized water to shore/platform for conversion to electricity and desalination to supply clean power and desalinated water.
The system is expected to have a peak effect of minimum150 kW, being able to produce 350,000 kWh and 28,000 m3 desalinated water per year.

The W2EW project plan has been structured in 5 work packages as follows:

• WP1 Management
• WP2 Commercial scale system requirements, specifications and design finalization
• WP3 Build market confidence-Integration, demonstration and qualification
• WP4 Build market recognition- Dissemination and communication
• WP5 Commercial exploitation

WP1 and WP2 will be led by Vryhof, WP 3 and WP5 by Wavepiston and WP4 by Ener.Med.

All work packages are currently ongoing.

The physical installation has been moved to Gran Canaria. Isola Piana, Sardinia, will still be used as a case study.

The COVID 19 crisis had an impact on the project development delaying some of the planned tasks. However the project is currently running and the consortium has been working on the new location and the tasks to prepare the installation.

Concerning the site data and potential installation location, the consortium is working on the specific location and contract with PLOCAN.

First versions of the business plan, and dissemination and communication plan have been finalized.

The installation has started at PLOCAN Offshore Platform in the island of Gran Canaria. The Power Module & RO container already installed. All parts of export pipe are ready for installation.
The overall project goal is to integrate the partner’s technologies to demonstrate and commercialise the W2EW solution for power production and desalination.

The partners expect to create the first commercial zero emission system for electricity and freshwater production.

On top of that, this project proposes several positive impacts that will be produced throughout the project and in the future, thanks to the benefits of the innovative solutions.

We will improve the innovation capacity and strengthen the competitiveness and scale-up of the industrial partners, which will enable the opportunities for companies in the sector of renewable energy and desalination.

All of these expected impacts will contribute to the positive impact at EU level in several areas as following:

• Economic Impacts: improving the EU position in the renewable energy market, increase the activity of the companies involved, over 200 new jobs will be created.
• Societal Impacts: Innovative solutions for islands and isolate coastal communities (clean energy and fresh water)
• Environmental Impacts: Reducing the CO2 emissions, producing fresh water from renewable.
