Competitive Wave Energy on Islands

Project description

Competitive Wave Energy

Wave energy is a viable alternative to fossil fuels, and competitive with other renewable energy sources. In this context, the EU-funded Wavepiston project will develop a disruptive technology that can demonstrate wave energy potential, ensuring low cost per kWh. The technology works thus: when waves roll along the energy collectors, plates are moved back and forth. The moving plates pump seawater into a pipe. The pipe leads the pressurised water to a turbine and/or a reverse osmosis system in a dry and easily accessible location for energy conversion and/or desalination. This low-weight and low-tech system is easy to transport and to assemble on-site. Maintenance can also be carried out without specialists.


Wavepiston is developed on the shoulders of the first-generation wave energy technologies. Due to its low weight, low-tech design, simple installation and operations & maintenance, Wavepiston will be the disruptive technology that can make wave energy competitive with the other renewable energy sources.

Our prototype test and Phase 1 feasibility study have confirmed this potential. The Wavepiston system is easy to assemble on site by local staff and can be deployed from a regular tug boat, just like operations and maintenance can be carried out without expensive specialists.

In the Phase 2 project we will install a full-scale Wavepiston demonstration system to demonstrate the energy potential, durability and survivability ensuring a low cost per kWh.

In the first step our customer focus is islands and isolated coastal communities. We already have the first 4 commercial customers in the pipeline; Isola Piana at Sardinia, Ebeye at Marshall Islands, Siargao at the Philippines and the Alidhoo J-resort at the Maldives. During Phase 2 we will prepare the first commercial projects together with professional energy project developers. This will enable us to start the commercialisation right after the finalisation of Phase 2.

The Wavepiston technology is protected by several patents.

The Phase 2 project plan has 6 work packages; WP1 Management, WP2 Preparation for the full scale demonstration, WP3 Manufacturing demonstration system and site installation, WP4 Demonstration and qualification, WP5 Business plan, commercial exploitation and dissemination WP6 NEC Requirements
