CEFOW: Clean Energy from Ocean Waves
The European Commission’s research and innovation programme Horizon 2020 has granted €17 million for the Clean Energy from Ocean Waves (CEFOW) research project coordinated by Fortum.
CEFOW aims to deploy advanced multiple wave energy converters (WECs) with improved power generation capability and demonstrate that they are able to survive challenging sea conditions over a period of several years. In addition, a realistic roadmap will be developed for cost reduction to bring the levelised cost of wave power down nearer to commercially viable level in the near future. CEFOW also has a fantastic starting point in that the devices will be deployed at EMEC, the world’s leading test facility for wave and tidal energy generators, where all the required infrastructure, including grid connection and permits, are already in place.
Europe is today unquestionably leading the way in wave power development. The most advanced wave power demonstrations have been performed in the UK and showed the feasibility of power generation with single device deployments and MW-scale performance within several testing periods of several years. The next step beyond this is to deploy arrays of wave devices.
CEFOW is aiming to be the first project to grid connect an array of wave devices in the UK and to create an efficient supply chain to support larger wave power projects in the future.
The CEFOW project will see two Wello Penguin WECs deployed as an array at the EMEC grid-connected wave energy test site.
The CEFOW project aims to demonstrate advanced ocean WEC technology to increase the speed of wave power development and decrease the levelised cost of ocean energy by 30%. This target can be reached by:
- Improving the availability and performance of the Penguin wave device;
- Tailoring the solution with low life-cycle cost in mind for long term deployment; and
- Creating a cost efficient supply chain to support much larger wave energy deployments in the future.
The five year demonstration project at EMEC will offer unique and valuable information not only about the weak points of different components but also the real cost levels of long term marine operations, component price development and decommissioning costs.
The project outcomes and results will be disseminated for the benefit of the ocean energy industry through published reports. These reports can be downloaded on the CORDIS website.
CEFOW Periodic Report Summary | Period 1
This report summaries the progress of the project during the first period between 01/06/2015 and 31/03/2017. This included the transportation and deployment of WEC1 at EMEC in Orkney, Scotland.
Measurement Plan | Work Package 7
This plan presents the measurements to be carried out during the testing of the 3 Penguin WECs to verify whether the quality of electrical powered supplied to the national grid complies with EMEC requirements, the efficiency of the WEC(s) with respect to ocean wave power available, as well as to ensure that the WEC(s) can operate safely and sustainably.
Environmental Impacts, Health & Safety | Work Package 6
Work package 6 within the CEFOW project is currently conducting device-specific research to investigate responses of seals, seabirds, fish and seabed organisms to the deployment of single and multiple Penguin wave energy converters at EMEC. The results will aim to aid industry and regulators regarding wider-scale deployments of renewable energy technology and potential environmental responses. As the work package progresses, the Universities of Exeter, Plymouth and Uppsala present on the advancements they are making through CEFOW, these presentations can be viewed below:

Led by Fortum, CEFOW is supported by a range of project partners with a vast amount of expertise in onshore renewable energy:
- Fortum: Fortum, a multi-national energy utility, believes that a transition to a solar economy, where energy production is based solely on renewable energy sources, is inevitable, although gradual. As an inexhaustible and emissions-free energy form, wave power can play an important role in the future, and that is why it is also a key focus area in Fortum’s research and development work. Fortum is responsible for coordinating the CEFOW project which will take place at the EMEC test facility, where Fortum has signed a leasing agreement for a grid connected wave power array.
- Wello: Finnish wave energy device developer Wello has already developed and successfully tested a single Penguin device at EMEC in Scotland in 2013. The Penguin device is one of the most advanced devices today, when measured in terms of power conversion capability and survivability. Penguin is also the only semi-permanently deployed megawatt scale floating wave energy converter. The CEFOW project will see three Penguin devices deployed at EMEC starting in 2017.
- EMEC: The three Penguin WECs will be deployed at EMEC’s grid-connected wave test site at Billia Croo, off the west coast of Orkney, Scotland. In addition to being the test site of choice for the CEFOW project, EMEC are also leading the dissemination and communications activities for the project.
- Green Marine: Green Marine’s involvement in the CEFOW project is to design a safe & cost effective installation and maintenance plan along with the other partners. Green Marine will be responsible for installing the mooring infrastructure, cabling and installing the Penguin devices onsite along with ongoing maintenance over the full term of the project, using our own vessels and experienced crews.
- Plymouth University: Plymouth University facilitates the sustainable development of wave renewable energy by assessing benthic change, the ecosystem functional relevance and provides advice to developers and regulators for potential mitigation measures. As part of the CEFOW project they will complete the benthic spatial and temporal baseline survey of the EMEC site using towed flying video and produce a research plan. They will annually monitor the impact of the Penguin device(s) and associated management practices and report associated change in seabed biodiversity and integrity.
- University of Exeter: The University of Exeter combines world class research with excellent education at its campuses in Exeter and Cornwall. It is a member of the Russell Group of leading research-intensive universities and are leading on the ‘Environmental Impact and Health & Safety’ work package in CEFOW, and tasked to monitor the effect of the Penguin device(s) on the mobile seabed faunal community and seabird interactions/behaviour.
- Uppsala University: Uppsala University has a vast amount of experience in developing its own linear generator wave energy converter which is also the base for another wave energy technology, Seabased. Uppsala has been running the Lysekil test site for wave energy since 2004 and has contributed greatly in environmental studies related to wave energy. Uppsala university will be involved in work relating to the grid connection, measurements and power quality of the Penguin device. They will also be involved in environmental monitoring by deploying sonars and eco-sounders.
This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 655594.
