FRANCE – Observer

The French tidal power engineering group Sabella has been successfully testing the D10 prototype (500 kW unit) connected to the local grid since September 2015, installed at Fromveur Strait, close to Ouessant (Ushant Island offshore Britany), in collaboration with Akuo Energy. This is the first of a 2 MW array planned for this site. In January 2016, the tidal turbine achieved 50 MWh of electricity production.

The Paimpol-Bréhat project, with total installed capacity of 1 MW, jointly developed by DCNS and EDF with OpenHydro technology, has already seen the installation of the first of two 500 kW tidal turbines in France in January of this year (off Île-de-Bréhat near Paimpol in Britanny). The second turbine is on site and will be connected to the grid over the next few months.

Two tidal array projects are also in the pipeline at Raz Blanchard (Alderney Race, Normandy): 14 MW for the Normandie Hydro project (EDF/DCNS) and 5.6 MW for the Nepthyd project (ENGIE/Alstom-GE).

NEMO, the 10 MW ocean thermal energy project to be developed off the west coast of Martinique in the Caribbean Sea, is benefiting from the complementary know-how of two partners - DCNS and Akuo - with NER300 support. OTEC is seen in France as an opportunity for non-connected islands. Recently, DCNS has signed a Memorandum of Agreement (MoA) with the OTEC Centre of the Universiti Teknologi Malaysia (UTM OTEC) to conduct together a pre-feasibility study aiming at identifying the potential opportunities of developing a pioneer OTEC plant on the Malaysian island of Layang-Layang.



 “Partnership for Danish Wave Energy” is a network of active Danish wave energy developers stimulating innovation and collaboration on wave energy development in Denmark.

The Energy Technology Development and Demonstration Programme (EUDP) has provided funding for testing a prototype of WavePiston at DanWEC and for Weptos to be tested in a smaller scale in a sheltered site in Kattegat.

WavePiston was damaged by a passing vessel ignoring the marked DanWEC test site area but will be re-installed this summer. Crestwing is building a ¼ scale device for installation in Kattegat this summer.

WaveStar is presently in the harbour of Hanstholm and will be decommissioned. At the International Energy Conference on Ocean Energy (ICOE) in February this year, WaveStar shared its experience on operation and maintenance over 4 years of power production at sea. Further performance data from the WaveStar has been incorporated in the standards series on marine energy under IEC DTS 62600-102.

Finally, EUDP has funded an ongoing project on mooring solutions for large Wave Energy Converters coordinated by Aalborg University – in this project Floating Power Plant, WaveDragon, Leancon and KNSWING are participating in order to investigate a common and more economic mooring system.



The German company SCHOTTEL HYDRO and its subsidiary, the Nova Scotia renewable energy company Black Rock Tidal Power Inc. (BRTP), have raised CAD10.5 million  of private equity and an additional CAD4.5 million  commercial loan to develop their instream tidal project (2.5 MW) in the Bay of Fundy, at the demonstration site FORCE.

NEMOS, a German wave energy developer, has been testing a 1/5 scale device at the Nissum Bredning Test Site in Denmark; the full scale prototype is under preparation expected to be installed at Hanstholm in Denmark during 2016 and 2017.



India joined the OES in April this year!

The commitment of the Indian Government to reduce carbon emissions has increased in recent years; renewable energy is considered in the Government’s plans to be an important part of India’s sustainable solution. There are 3 organizations active on ocean energy research: the Indian Institute of Technology in Madras, the Ministry of New Renewable Energy and the National Institute of Ocean Technology (NIOT). Additionally, the Indian Navy is committed towards harnessing power from ocean renewables. 

The Ministry of New and Renewable Energy (MNRE), acting as the nodal Ministry for all matters relating to new and renewable energy, has recently set up a technical committee for evaluating marine energy devices ready for open sea with NIOT as the technical experts.

Also, the Indian Navy is exploring the possibility of setting up an OTEC plant off Port Blair (Bay of Bengal) with support from the Ministry of Earth Sciences (MoES). NIOT is in the process of setting up a laboratory for experimental studies on OTEC powered desalination.

NIOT is involved in several R&D projects on wave and marine current energy, including the improvement of the Backward Bent Ducted Buoy (BBDB) performance by re-designing the air turbine. The design and fabrication of first prototype of a cylindrical navigational buoy using this technology is under way. Another research focus is the development of marine hydrokinetic turbines suitable for low current speed.




The Marine Institute has been working together with the Sustainable Energy Authority of Ireland (SEAI), MaREI (UCC) and SmartBay Ireland to enhance the ¼ scale Galway Bay Ocean Energy Test Site. In 2014-15 the Government  supported with €3 million the cable deployment as well as ongoing management of the test site. Further governmental support of €2 million during the past 2 years has been allocated to the full scale test site named AMETS for consenting preparation and grid connection and further €15 million to Lir National Ocean Test Facility. This test facility at Beaufort consists of state-of-the-art wave tanks and electrical rigs that allow for scaled testing in a controlled environment throughout the early stages of device development (TRL 1-4).

In November 2015, SEAI announced a Memorandum of Understanding with Apple to promote the development of ocean energy in Ireland. Apple has committed a €1 million fund that will help developers test their prototypes at the Galway Bay Test Site.

Last year, over €4.5 million were granted to 14 projects through the Ocean Energy Prototype Development Fund administered by SEAI. This funding scheme designed to support wave and tidal energy devices testing with emphasis on industry-led projects has enabled a number of Irish developers to progress, among them:  GKinetic Energy deployed its 1/10 scale tidal energy device in Limerick Docks, Ireland; Sea power and Limerick Wave Ltd. completed the design of its 1/4 scale demonstrator unit ready to be tested this summer in Galway Bay; OE Buoy has been testing at the US Navy Wave Energy Test Site (WETS), Hawaii.



Two years ago, the Japanese Government authorised the development of a number of test sites in Japan for wave, tidal and offshore wind aiming to accelerate deployment and development of marine renewable energies in Japan. The development of these infrastructures has been progressing since then. 

Up to now, 15 R&D projects on ocean energy will run until 2017, funded by Japan’s New Energy and Industrial Technology Development Organization (NEDO). One of these projects is an underwater floating turbine system conducted by IHI Corporation and Toshiba Corporation together with the University of Tokyo and Mitsui Global Strategic Studies Institute. The system is driven by the ocean current with two counter-rotating turbines, anchored to the sea floor and floating like a kite.

Japan is reputed to lead the world in the research and development of OTEC. Since June 2013, on Kumejima in Okinawa Prefecture, southern Japan, a 100kW class onshore OTEC facility has been operating.



In Monaco, the sea is used as a renewable energy source for the development of a heat pump system. In 2015, 70 heat pumps produced 17% of the energy consumed in the Principality.

One oceanographic buoy has been installed for  more than one year in the coastal area of Monaco as part of the CANDHIS (National Centre for Archiving Swell Measurements) network:

The company SBM Offshore based in Monaco is moving ahead with the development of their wave energy technology using electro active polymers for the Power-Take-Off system. After a series of tests, SBM Offshore is investigating the feasibility of deploying a scale prototype in 2017 and is inviting industry partners to the project.



The Dutch company Bluerise will soon be building a seawater cooling plant on Curaçao Island in the Caribbean Sea with full support from the Curaçao Government. The core of the project is the construction of a SWDC (Seawater District Cooling) system, in the coast near to the island's airport complex. In addition, a 500 kW pilot OTEC plant (Ocean Thermal Energy Conversion) is being built.

Tocardo is developing plans for the installation of an array of eight T2 turbines at the European Marine Energy Centre (EMEC) in Orkney. Tocardo’s T2 turbines have already been tested in the Netherlands at the Eastern Scheldt storm surge barrier (Deltaworks). Installation of this 2 MW project at EMEC will start next year.

The Dutch company Redstack has been active over several years on salinity gradient research and is now focusing on the development of more efficient and cheaper membranes. Although there is an important perspective for energy production with this technology, the early stage of development still requires research activities and long-term support.



WaveEI, the floating wave energy device developed by the Swedish company Waves4Power has been tested in beginning of this year at Runde Environmental Centre located on Runde Island on the Norwegian west coast.

Other wave energy companies - Havkraft, Ocean Energy Ocean (Storm Buoy) and Langlee (Langlee Robusto) -are actively working on research and development; a number of Norwegian tidal developers - Deep River, Tidal Sails, TideTec and Flumill – have recently shown progresses.

Andritz Hydro Hammerfest, the company founded in Norway in 1997 by the local utility company Hammerfest Energy (currently owned by Andritz Hydro, Iberdrola and Hammerfest Energi) is now taking the step into commercial delivery. Andritz Hydro is also part of the Meygen tidal energy project.



The Minister of the Sea has been assigned with the responsible for implementing a cross-cutting strategy for the ocean. Under this strategy, offshore renewable energy has special relevance.

In March this year the Portuguese Government created the Inter-Ministerial Working Group “Energy at Sea” to discuss a development model for Portugal to boost investment in R&D on marine renewable energies to develop competitive industries with services and products of added value. This group is formed by members of the Government for the sea, for the energy sector, for the environment, for defence and for the area of science and technology, including a number of representatives from national agencies, state laboratories, universities and innovation centres. For a period of four months this team has prepared a relevant report to serve as the basis for a public discussion.

AW-Energy is further developing the WaveRoller wave energy farm in Portugal. A new full scale grid connected device will be installed in Peniche and the company is presently applying for the licence. Bombora Wave Power, an Australian company, is working on the design of its real scale prototype for testing in Portugal.

A long term R&D plan prepared by the Government for the period 2015 -2025 and approved last year has a set of key actions for ocean energy including the construction of open sea testing facilities for wave and current devices, enhancing market incentives for ocean energy, priority on hybrid ocean energy systems and application of wave energy technologies for remote islands.

The construction and commissioning of the Yongsoo OWC pilot plant (2x250kW) located offshore Jeju Island is now concluded and expected to be officially inaugurated in June this year.

The construction of a prototype of the Floating Pendulum Wave Energy Converter (FPWEC) started in May this year and is expected to be launched into the water next year. It uses hydrostatic power transmission and a synchronous generator (300kW, 11kV).

Further three relevant R&D projects funded by the Government have been initiated this year by the Korea Research Institute of Ships and Ocean Engineering (KRISO):

1.       The K-WETEC (Korea Wave Energy Test & Evaluation Centre) starting in May this year and to be completed in 4 years, with a budget of $17 million for the first phase corresponding to 5 berths with total capacity of 5 MW; an expansion to 20 MW in a second phase is planned;

2.       Energy Storage in remote islands using small oscillating water columns (OWCs) wave energy devices integrated in breakwaters;

3.       1 MW OTEC demonstration project on a floating platform located 6km offshore at 1300m water depth to be moved to Kiribati (under a Memorandum of Understanding between Kiribati and the Korean Government).



Mutriku OWC plant in the Basque country, operated by the Basque Energy Agency - Ente Vasco de la Energía (EVE) – since 2011, has reached 1GWh of cumulative power this year.

EVE also contracted the wave energy developer Oceantec Energías Marinas to install a prototype off the Basque coast, at the BiMEP test centre, which has all the permission to install wave energy devices and is equipped with 4 cables of 5 MW each, an onshore substation and a monitoring system.

Oceantec with Tecnalia have been further awarded a contract from Wave Energy Scotland for the development of a novel PTO. This project was one of the 16 successful applications for innovative PTOs. 

OPERA is the new R&D project funded by the European Commission (H2020) initiated in February this year: It is coordinated by Tecnalia in collaboration with Oceantec (ES), BiMEP (ES), EVE (ES), IBERDROLA E&C (UK), GLOBAL MARITIME (UK), DNV (UK), University of Edinburgh (UK), University of Exeter (UK), KYMANER (PT), IST (PT) and University College Cork (IE). This project will collect and share 2 years of open sea operating data to validate and de-risk four industrial innovations with the final aim of reducing wave energy cost.



Seabased Industry AB, a spin-off company from Uppsala University, is building a wave energy park outside Sotenäs on the Swedish west coast, together with Fortum and with support from the Swedish Energy Agency: 36 wave energy converters are in place, with a total installed capacity of 1 MW. This corresponds to the first phase of the project which will be evaluated before a possible second phase. In January 2016, the first converters started delivering electricity to the grid. Seabased has also signed a contract with the Ghanaian company, TC Energy, for a large wave energy plant in Ghana in several steps, where the largest step corresponds to 14 MW (140 generators).  The work on its 5 MW project has already been initiated expected to go into operation around the end of 2016, or early 2017. Six devices have already been installed offshore the coastal town Ada.

On 11 May, the OES delegates visited the factory of Seabased in Lysekil and had the opportunity to see all steps of the fabrication process of the electrical generators and floating buoy.

With support from the Swedish Energy Agency the company Waves4Power installed their full scale wave energy converter at Runde, Norway in February 2016. Next step will be launching the collection hub and cable for grid connection.

The national ocean energy programme received 26 applications in the second call, which was even more than in the first call. The final decisions on which projects will receive funding will be soon taken.

Furthermore, OCEANERA-Net, a cooperation between member states and with support from the commission, received 19 pre-proposals in the second call. 11 of these had Swedish partners which show that the Swedish ocean energy sector is very active.

For the first time the Swedish Energy Agency organised a conference on ocean energy. The Conference took place on the 11 – 12 May in Smogen, after the ExCo meeting.

The creation of Wave Energy Scotland (WES) underlines the Scottish Government’s support for the wave sector. Through Wave Energy Scotland, the public sector is funding a series of procurement calls, aimed at encouraging collaboration between device developers, researchers and large engineering firms. This is a new model of support for the wave sector, encouraging deeper collaboration.

So far, two competitive project calls were launched last year.  The first one was for Power Take-Off (PTO) systems (PTO) and over £7 million has been awarded to 16 projects (phase I); the second call focused on novel wave energy converter devices and over £2.25 million were awarded to 8 technology developers and consortia. Metrics of affordability, reliability, survivability and performance were assessed during the evaluation process.

The two final PTO awards have been announced and were made to Trident’s WaveDrive project and to Exceedence Hydraulic PTO project.

In February 2016, Wave Energy Scotland (WES) announced the start of two landscaping studies: one in Materials conducted by the Institute for Materials and Processes at the University of Edinburgh and another on Structural Forces conducted by Arup’s team.

Early this year, DOE has launched a new call to support R&D on marine energy projects in two Topic Areas: (1) design and test full scale wave and current energy technologies ($16.05 million), and (2) support the development and innovation of technologies for monitoring the potential environmental impacts of marine energy technologies ($5.95 million). This call closed on 26 May 2016.

In December 2015, the U.S. Department of Energy (DOE) awarded $10.5 million for six organizations to support the design and operation of innovative marine energy systems: Dehlsen Associates, M3 Wave LLC, Oscilla Power, Columbia Power Technologies, Igiugig Village Council and Verdant Power. These teams will address the challenges of designing devices to operate in the ocean environment for years and reduce uncertainty regarding marine installation, operations, and maintenance.

Another initiative from the U.S. Department of Energy (DOE)‘s Water Power Program is the Wave Energy Prize (, a public prize challenge designed to attract innovative ideas from developers new to the industry and next-generation ideas from existing developers by offering a monetary prize and providing an opportunity for tank testing in national facilities. In March this year DOE announced the 9 finalists (from the 17 applications) that are now proceeding to the next phase of the competition. Each of the finalists will receive seed funding from DOE to develop 1/20 scale models of their wave energy technologies to be tested in the summer of 2016.
