Japan is leading the preparation of a detailed work program for investigation and evaluation of OTEC resource to be approved by the ExCo and conducted by a group of interested countries in the topic.

Under Task 5 “The Exchange and Assessment of Ocean Energy Device Project Information and Experience” a serious of workshops with key experts have been organized by NREL on behalf of US Department of Energy covering topics such as open water testing, computational modeling tools and reliability issues. The final workshop to be held in 2016 is expected to cover “Ocean Energy Policies: Lessons Learnt”. The outcomes of previous workshops are public available.



At the federal level, the Department of Natural Resources Canada, under the Marine Renewable Energy Enabling Measures programme, continues to take a lead role towards the development of a policy framework for administering marine renewable energy activities in the federal offshore.

At the provincial level, the Government of Nova Scotia has introduced legislation regarding the administration of tidal energy projects in the provincial waters of the Bay of Fundy and the Bras d’Or Lakes. 

Major activities in Canada are focused on the Bay of Fundy. At the FORCE tidal demonstration centre, the substation has been upgraded to 30 MW. Through the Government of Canada’s Clean Energy Fund, FORCE has received $20 million for the cables installation and $4 million for the FAST programme (Fundy Advanced Sensor Technology platform). A new instrument for high precision measurement of velocity and turbulence will be attached to the FAST instrumentation platform, to assist in the engineering of turbines. This new instrument, along with the FAST platform, is expected to be deployed in the water at FORCE before the end of the year.

The current berth holders at FORCE include: Atlantis Resources (Lockheed Martin, Irving and DP Energy), Black Rock Tidal (Schottel), Cape Sharp (OpenHydro, DCNS and Emera) and Minas Basin.

Interest in wave energy in Canada continues to focus on the West Coast Wave Initiative (WCWI) established by the University of Victoria. Also active is the Canadian Hydrokinetic Turbine Test Centre in the Winnipeg River, Manitoba, permitted since 2013 by the University of Manitoba. These two programs have received over $4.5 million in federal funding from Canada’s ecoENERGY Innovation Initiative.



The State Oceanic Administration (SOA) together with the Ministry of Finance (MOF) are continuing to fund R&D on marine renewable energy. In 2015, a global amount of RMB 100 million has been allocated for 3 projects.

Since 2010, five pre-feasibility studies have been conducted for tidal range energy projects (Jiantiao, Rushan Estuary, Bachimen, Maluan Bay and Oufei), which have now been completed.

After the successful 2-year testing of the 10 kW wave energy device known as Sharp Eagle, Guangzhou Institute of Energy Conversion (GIEC) with China Shipping Industry Co. has begun to develop a 100 kW device which was assembled in April 2015 and  is planned to be deployed before the end of the year.

The 60 kW semi-direct drive horizontal-axis turbine deployed near Zhairuoshan Island for sea trials since May 2014 has achieved 20MWh in one year of operation. The project is now progressing for a 300 kW turbine, led by Guodian United Power Co.

The LHD L-1000 turbine, a 4×300kW modular turbine, has been assembled and will be deployed on Xiushan Island before the end of the year.

Two open sea testing sites are progressing in Wanshan, Guangdong  and in Zhoushan, Zhejiang; this last one was initiated by China Three Gorges Corporation in June 2015 with a total investment of 135M RMB.

A R&D project on OTEC on Xisha Islands was initiated by NOTC in April 2015.



In Denmark, several different wave power systems at different scales have been developed and tested with the support from national energy development programmes EUPD and

During 2015, the Danish "Partnership for Wave Power" have prepared a Roadmap with the goal of international commercial success of the wave power sector by 2030.  Twice a year the partners meet and share their experiences from R&D and tests at sea.

At the DanWEC Hanstholm test centre, two wave rider buoys have been launched this year and a seabed survey has been carried out over an area in the sea south of the harbour accepted by authorities for test purposes. A pre-requisite for achieving the long term goal includes in particular the support for prototype testing at DanWEC. The level of funding required is estimated in the order of DKK 5-20 million/year.



Japan is progressing with approval of testing centres for ocean energy: there are now six sites approved for demonstration projects on wave energy (Niigata and Iwate), tidal current (Niigata, Nagasaki and Saga), ocean current (Niigata) and OTEC (Okinawa).

The Government has an R&D programme in place (2011 – 2017) administered by Japan’s New Energy and Industrial Technology Development Organization (NEDO) to enhance ocean energy development aiming at progressively reducing the costs of the energy produced.  A few projects are progressing from tank testing to demonstration at sea.

Okinawa OTEC plant of 100 kW has been operating continuously, grid-connected, on Kume Island for almost two years. There has been a close collaboration between this project and the OTEC project in Hawaii conducted by Makai Ocean Engineering at the Natural Energy Laboratory of Hawaii Authority (NELHA). In August this year Japan signed a MoU with USA, during the dedicated ceremony of the Makai OTEC plant to celebrate the beginning of power production at their facility. Both the Okinawa and Makai OTEC demonstration facilities are providing valuable data and this is seen as an opportunity for combined US and Japanese experience on OTEC developments.



As part of the Mexican policies to foster the renewable energies in the country, the Ministry of Energy (SENER) has decided to support academic-industry alliances in order to promote and accelerate the development of ocean energy. A call has been launched for a centre of excellence on ocean energy and only one consortium of 45 institutions has applied, consisting of academic institutes and private companies lead by the National Autonomous University of Mexico (UNAM).

The CeMIE-Oceano (as stands for its name in Spanish Centro Mexicano de Innovación en Energía del Océano) is expected to be launched soon by the Mexican Government and will respond to the need to develop a better understanding of the ocean energy resource in the country and provide a solid support to the development of a national ocean energy industry, promoting innovation, scientific research and technological development. The Government will provide a seed grant for about 20 million dollars to cover its operation during the first four years.



Tocardo and Huisman have recently installed an array of 1.2 MW (5 Tocardos T2 tidal turbines) in the Eastern Scheldt storm surge barrier, which is the largest of the world-renowned Delta Works series of dams and storm surge barriers, designed to protect the Netherlands from flooding from the North Sea. The T2 turbines are fitted with bi-directional rotor blades thus enabling to generate electricity during ebb and flood.

BlueTec, a floating device designed for producing electricity from tidal currents in remote areas has recently been connected to the grid. It is the first prototype of 200 kW that can be deployed as a single unit or in a small array of multiple units.

There are relevant R&D activities in OTEC and Salinity gradients: A Dutch company named Bluerise, a spin-off company from Delft University of Technology, is developing a project on OTEC near the Caribbean Island of Curacao. REDstack is conducting a salinity gradient project of 15 kW using reverse electro dialysis.



Since March 2015, there is an electronic submission procedure for licensing projects at sea. This follows last year’s publication of the Basis of Planning Policy and Management of National Maritime Space.

A new R&D project - WETFEET - funded by the European Commission programme H2020 started in June 2015. It is a 3-year project with a €3.5 million budget led by WavEC and involving other 11 European partners. The project aims to understand and find solutions to the constraints of wave energy technology.

AW- Energy (Waveroller) is now developing a new 350 kW unit due to be deployed next year in Peniche (Portugal). This is the first of a series of 5.6 MW array to be developed at that site with NER300 funding.

Pico plant continues operational in the Azores and supplying electricity to the grid.



In Singapore, regional efforts are being pursuit to develop marine renewable energies in the country. Example of this is the recent workshop with a roundtable discussion about the challenges in the renewable energy sector in Southeast Asia, as well as the roadmapping exercise under preparation involving all relevant stakeholders.

In terms of research, Energy Research Institute @ NTU is focused in development of tropical solutions of ocean energy systems specifically in tidal and wave energy towards remote conditions such as islandic states.

Offshore Renewable Energies are attracting much interest in the country: Asia Clean Energy Summit organized this year in Singapore (27-28 October 2015) included two plenary sessions and 7 technical sessions on offshore renewable energies with 43 oral presentations on the topic.

At the SEAcORE meeting on 26 October, attended by key representatives from Brunei, Thailand, Malaysia, Vietnam, Singapore and Philippines, a Memorandum of Understanding (MoU) was signed with the ASEAN Centre for Energy. Following this meeting, an ocean energy country report will be prepared.

South Africa has a renewable energy policy which specifies targets for the renewable energy deployment but nothing specific for marine energy.  Currently, there is an increased interest in energy storage due to the increased share of renewable energy on the South African grid. There is an initiative that is looking to unlock the potential of the ocean economy and through this the country is hoping to raise the profile of marine energy.  As an initial step, ocean data is being collected from the shipping industry especially now that Eskom has stopped monitoring the Agulhas current.  There have been two projects announced, one overtopping device on an abalone farm by the company Mean SeaLevel (Pty) for 5.45 MW and another ocean current one off the Durban coast by Hydro Alternative Energy (HAE).



Bimep, an open sea test site in the Basque Country, was officially inaugurated in July and is now working with the first users who will shortly install several trial devices. An innovative public procurement was tendered by bimep, which closed on November 20th, to develop and install a submarine hub for electrical connection.

The Basque Energy Agency (EVE) has awarded a pre-commercial public procurement contract to the wave energy developer OCEANTEC Energias Marinas to supply its technology for the deployment off the Basque coast. This 2.5 million contract will allow OCEANTEC moving forward into a TRL7 stage after testing, during one year, of a low power prototype connected to grid at bimep. A new call to support open sea testing has also recently been launched by EVE, closing on December 31st.

After 4 years of continuous operation with a cumulative production of over 1GWh, Mutriku Wave Power Plant is now being offered as a test site for OWC components.

The public Consortium PLOCAN manages an open sea test site in Canary Islands inaugurated in April 2014 and has been working with different developers to test wave energy converters without grid connection: the Spanish companies PIPO Systems and Wedge Global and the Finish WELLO. A public tendering will be launched during 2016 to install the submarine electrical infrastructure with a power capacity of 15 MW.

Regarding the Undigen+ Project (partially funded by the Spanish Ministry of Economy and Competitiveness), based on Wedge Technology (Wave Energy Converter with direct drive power take-off), and currently carried out in PLOCAN, the industrial-scale W1 device´s ocean tests have kept on showing an outstanding performance (once duly improved the braking & blocking systems). Such effective generation results achieved during the last months are being presented to the offshore renewal energy industry for the immediate pre-commercial stage.



The Swedish Ocean Energy Programme (2015 – 2018) has a budget around € 5.6 million for 4 years. Around half of this budget was allocated to the first call, in which 7 projects out of 23 was approved.  The second call has just opened.

Further, within the first call of OCEANERA-NET (European initiative to coordinate research among European funding agencies), the OCEANERA-Net consortia has approved 9 projects out the 18 evaluated. 4 of these projects have Swedish partners.

Two new demonstration projects with Swedish development companies will take place:

·         The testing of the 1:2 scale wave energy prototype developed by the Swedish company, CorPower Ocean AB, to be installed at EMEC, Orkney (Scotland). The project is supported by the Swedish Energy Agency.

·         Minesto, the company that is developing a new concept for operation in low velocity currents, called Deep Green, is planning a 10 MW project to be installed in Welsh waters (Holyhead Deep) 2017-2019. In parallel, the company is also developing a 1:4 scale device in Northern Ireland (Strangford Lough).

Further on progress is being made in the wave energy demonstration project in Sotenäs (western Sweden). The project is carried out by Seabased Industry AB and the Finish utility Fortum with support from the Swedish Energy Agency.  They have now all devices in place (1 MW in total in the first stage) but is not yet grid connected. Another project is being planned where the company Simple Blue Energy intend to use Seabased´s wave energy technology for installations at the WaveHub site.

A fourth Swedish development company, Waves4Power AB will soon start the installation of their demonstration project at the Runde environmental centre in Norway. The project is supported by the Swedish Energy Agency.
