CEFOW Report Summary

Project ID: 655594

Periodic Reporting for period 1 - CEFOW (Clean energy from ocean waves)

Reporting period: 2015-06-01 to 2017-03-31

Summary of the context and overall objectives of the project

The most advanced wave power demonstrations today have 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 multiple wave energy converters in MW-scale with improved power generation capability and demonstrate that they are able to survive rough sea conditions over a period of several years. Clean Energy From Ocean Waves (CEFOW) project has an exceptionally good starting point. It has a site in a wave power testing centre called EMEC (European Marine Energy Centre) with all the needed infrastructure, including grid connection already in place. In addition, the wave energy converter technology to be deployed in the project has already been tested and proven in real conditions in Scotland.

The ultimate purpose of the CEFOW is to increase the speed of wave power development, decrease the levelised cost of ocean energy by improving technical solutions used for multiple device system, and create an efficient supply chain to support larger wave power projects in the future. To reach these targets, the CEFOW consortium will improve the wave energy converter performance by 50% and raise its availability to 70%; develop new types of dynamic mooring and electrical connections suitable for multi-device deployment and deploy 3MW (three 1MW units) wave energy converters in real world offshore conditions in a grid-connected testing environment. In addition, CEFOW will study the feasibility of on-board and on-shore storage solutions and conduct thorough multi-year environmental, health and safety studies.

The consortium spans the full value chain from research organisations to wave converter technology developers, marine service providers and a large multinational utility company as the operator.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

The project started in June 2015 with goal to deploy and grid connect three 1 MW Penguin Wave Energy Converters (WECs) at Wave Hub in Cornwall UK. The original planning and specifications were done for the Wave Hub site. Due to unexpected problems in 2016, a decision was made and the Grant Agreement was amended to change the project test site to European Marine Energy Centre (EMEC) in Orkney Scotland. In March 2017, the first Penguin was successfully deployed and later connected to grid.

The main achievements of the reporting period (M1-22) include:
• Transportation of refurbished WEC1 to EMEC, Orkney
• WEC1 deployment
• WEC1 connected to grid
• WEC1 power production

The requirements and specifications were first defined for Wave Hub site, but later revised for EMEC site. The related WP1 has been finished. Existing Penguin (WEC1) went through maintenance and revision programme where some modifications to improve performance and reliability were made.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

At this stage of the project, there is no reason believe that the expected impacts mentioned in section 2.1 of DoA would not be realised, and thus all the impacts are still relevant. During the following periods, more information should be received concerning the project contributing to the impacts when all three devices will be operational with improved properties, installations and operation characters and array operations. During the first period, the main focus was on the installation of the existing 2009 designed device (WEC1) with only some improvements in anchoring.

Main impact of the project is that CEFOW will take one of the most promising wave power technologies closer to commercial phase. More specific impacts include 20% cost reduction in investment cost and 30 % savings in operation costs. The use of renewables will increase and CO2 emission in power production reduce.
