28th Executive Committee Meeting, 12-13 May 2015

The Executive Committee of Ocean Energy Systems (OES), an Energy Technology Initiative under the International Energy Agency (IEA), announces the outcomes of its 28th Meeting held in Kassel, Germany, on 12-13 May 2015, hosted by Fraunhofer IWES.

On the previous day, Fraunhofer IWES organized a workshop with a session on key markets with a deployment roadmap presented by Ireland, UK, China, Republic of Korea and USA. The workshop further addressed public and private R&D activities in the sector in Germany, R&D in industry for components and systems and success stories for market introduction of new technologies and services.

Comprehensive overviews of international activities and achievements on ocean energy were shared during the ExCo meeting, and are presented below.



OpenHydro has granted $6.4 million for a 2x2 MW tidal current energy demonstration project at the FORCE test site to be in place later in 2015.

Natural Resources Canada (NRCan) has launched a public consultation from December 2014 until March 2015 of the Marine Renewable Energy Enabling Measures Programme to engage coastal provinces and stakeholders on the programme background, aiming to obtain input on a proposed policy framework for administering marine renewable energy in the federal offshore. 

At a provincial level, there are several activities going on: The Government of Nova Scotia amended the Renewable Electricity Regulations under the Electricity Act to establish the feed-in tariff (FIT) approval process for larger scale developmental tidal projects.  This is intended to help ensure more private investment. Nova Scotia continues to lead Strategic Environmental Assessments (SEA), including an update for the Bay of Fundy which was  released in 2014.

While major activities in Canada are centred around tidal energy at the Bay of Fundy, there are several projects and initiatives underway in river and wave energy. The University of Victoria has recently established the West Coast Wave Initiative, which is a university/industry collaborative project.



The support from the Government has been essential in promoting ocean energy in the country, in particular the implementation of the Special Funding Programme  for marine renewable energies in the last 4 years with a budget over RMB845 million (€120 million).

The Chinese Government is developing a strategy for marine renewables, considering three goals for ocean energy: i) design and manufacture of tidal current energy arrays, ii) modular design and manufacture of wave energy devices, and iii) R&D of environmental-friendly technology for tidal range energy. Further, the Government has been structuring a strategy to advance ocean energy technology development until 2030, which includes the development of a few tidal and wave test sites and the utilization of ocean energy on remote islands.

Several devices have been tested in the sea: over 10 tidal current turbines with average capacity of 150 kW and 15 wave energy converters with average capacity of 50 kW: There are two operational tidal range power plants, and pre-feasibility studies are being done for another 4 sites; an OTEC prototype of 15 kW is under development; research on salinity gradient projects is progressing as well.

More and more Chinese companies are engaged in development of ocean energy. The market of ocean energy is emerging with 32 Chinese institutions (public and private sector) highly engaged in R&D.

A joint venture between Zhejiang Golden Eagle Group Co., Ltd (China) and IT Power Ltd (UK) was announced in March 2015 for the design and manufacturing of a new tidal technology. This is seen as an initiative to enhance international cooperation to accelerate the implementation of a national plan for ocean energy.



In Germany there are a few success stories for market introduction of new technologies and services for marine energies. Among them there are Bosch Rexroth, Andritz Hydro and Schottel Hydro.

Schottel Hydro has launched a new turbine called SCHOTTEL INSTREAM TURBINE (SIT) and has been testing a full scale unit at Portaferry (Strangford Lough) in Ireland with Queens University Belfast and IWES Fraunhofer within the framework of the EU-Project MARINET.

NEMOS is a new company established in 2012 developing an innovative wave energy system that can be coupled with offshore wind turbines. Within the EU-Project MARINET tests with a 1:5 scale device have been done at the wave tank of École Centrale de Nantes, France. In cooperation with German industrial partners the company is now preparing a full scale prototype for 2016. SINN Power is another German company moving ahead with the development of an innovative wave energy device. 



Ireland has in place a robust governance structure for the Offshore Renewable Energy Development Plan (OREDP) launched last year. The work is happening in six areas.

Environmental and Planning - a new Planning and Consent Architecture for Development in the Marine Area is being developed including a Digital Ocean Mapping.

Research - the MaREI Research Programme was launched for specific research areas related with marine energies.

Supply Chain - an Inter-Governmental Agreement to export renewable electricity to the United Kingdom was set up. In particular Ireland is developing their ports, particularly those along the western seaboard.

Enterprise Development - The Prototype Fund allows developers to progress in TRL since 2009; a budget of €4.5 million is allocated for 2015.

Grid - An initial market support scheme will be in place from 2016, funded from the public service obligation levy, equivalent to €260/MWh and strictly limited to 30 MW for ocean (wave and tidal).

Test facilities – Ireland continues to ensure appropriate infrastructure development: The Beaufort Test Centre Cork is expected to open in July this year, at Galway Bay test site the power and data cable have been deployed and work at the open sea test site AMETS is progressing on landside infrastructure.

In April this year a new area for demonstration projects (wave and offshore wind) at Iwate Prefecture was decided by the Government. Besides this one, other 4 sites were approved last year at Niigata, Saga, Nagasaki and Okinawa Prefectures.

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.  One of these projects is an underwater floating-type ocean current tidal energy turbine system developed by IHI Corp and Toshiba Corp.

Okinawa OTEC project has been operating continuously since June 2013 and it is now planned to be upgraded during the year (with a new cycle and new heat exchanger).         



The last 18 months have been challenging for ocean energy in Norway with three large companies deciding not to continue their development. However other players are active and progressing, among them:

  • Andritz Hammerfest Strom, a long time player in the field, achieved good results with the 1 MW prototype tested at EMEC; with its two previous prototypes HS300 and HS1000, 3 GWh in total have been produced; The Islay Array project has received NER300 support.
  • Havkraft is developing a wave energy device of the oscillating water column type with a Wells turbine - a prototype of 260 kW is currently undergoing tests.
  • Tidetec is developing a tidal barrage concept in collaboration with German and English partners.


In March 2015, the Portuguese Government launched an electronic submission procedure for licensing projects in the sea aiming to streamline the process. This follows the publication of the Basis of Planning Policy and Management of National Maritime Space last year, presenting a new vision and proposing new simplified procedures for the effective use of the ocean.

Enondas, manager of the open sea test site OCEANPLUG, published the regulation access for promoters on their website, as well as the geophysical and the environmental characterization of the site, after public consultation.

A new R&D project - WETFEET - funded by the European Commission programme H2020 will start in June 2015 and will run for 3 years with a €3.5 million budget. The project is led by WavEC and involves other 11 European partners. WETFEET has the overall aim to understand and find solutions to the constraints of wave energy technology. In particular, the project seeks to identify the reasons that have been delaying the sector's progress and propose viable solutions to improve the overall performance of new technologies.

Instituto Superior Técnico is progressing with their development of a Spar-buoy OWC with a bi-radial turbine. Good results have been obtained with the experimental tests conducted over the last years within the framework of the FP7-MARINET Project.

An Ocean Energy Development Planprepared by the Government is expected to be approved during the year. Key proposed actions include the construction of open sea testing facilities for wave and current devices, policy mechanisms for promoting ocean energy, hybrid ocean energy system including floating offshore wind and application of wave energy technologies for remote islands with micro-grid.

The 254 MW Sihwa Tidal Power Plant (10 turbines), operational since 2011, has reported increased annual productions of 466 GWh, 484 GWh and 492 GWh over the last 3 years. The goal is to achieve an annual production of 552 GWh, expected to represent an annual reduction of CO2 emissions of 315,000 tons. Feasibility studies for other three sites have been carried out.

Uldolmok Tidal Power Plant (2x 500 kW) continues operational since 2009. Yongsoo OWC pilot plant (2x 250 kW) on Jeju Island is expected to begin operation in 2015.

In previous years two experimental OTEC plants have been built, of 20 and 200 kW. The next step is the design of a 1 MW test bed during 2015, tentatively scheduled to be constructed in 2016~2018.



The new Renewable Energy Integration Demonstrator - Singapore (REIDS) initiative was launched by the Singapore Government in October 2014:  Nanyang Technological University (NTU) will build a hybrid micro-grid which will integrate multiple large scale renewable energy sources including an offshore test site. This initiative is expected to attract $20 million worth of projects over the next five years, in addition to the initial $8 million investment in the infrastructure. This project, located offshore at Semakau Landfill, will be suitable for small islands and isolated villages. Under this initiative, a feasibility study for the development of a marine energy testing facility is being carried out by a consortium led by ClassNK and the Energy Research Institute of Nanyang Technical University (ERI@N), with support from other leading research institutes and consultants including the European Marine Energy Centre (EMEC) and marine specialists such as Fugro.

NTU is collaborating in a joint 18-months project with the University of Strathclyde and the University of Southampton involving industry partners as well. This project, funded by the Energy Innovation Research Programme (EIRP) in Singapore, will lead to the development of a floating tidal test bed for South East Asia tropical waters.



Despite the current situation regarding lack of support to renewables, the ocean energy industry in Spain is progressing, with some interest from big players (Iberdrola, ABENGOA, REPSOL) and with enthusiastic Spanish technology developers.

Support exists from two regional Governments, the Basque Country and Canary Islands. Two open sea test facilities, bimep in the Basque Country and PLOCAN on Canary Islands, are in operation with devices in the water already or planned to be installed soon. Wedge Global has been testing its wave energy device in PLOCAN since February 2014. Additionally, there is some initial interest in two other regions Andalusia and Galicia.

In November 2014, the Basque Energy Agency (EVE) launched a tender of a pre-commercial public procurement for the development of a floating wave energy converter suitable for the Basque coast. OCEANTEC, a Spanish company with two shareholders (Iberdrola and TECNALIA) has been the only applicant which submitted the required documentation on time. The tendering process is still underway. Mutriku OWC plant in the Basque Country, promoted by EVE, has now more than three years of continuous operation and it is also working as a testing site.



The Swedish Energy Agency has recently issued a call for proposals under their national ocean energy programme. The first call is now closed and the evaluation process of the 23 proposals is going on.

CorPower Ocean AB will test a 1:2 scale prototype at EMEC, Orkney. It is a project developed in collaboration with Iberdrola and WavEC. Seabased Industry AB continues to develop the wave energy park outside Sotenäs together with Fortum and with support from the Swedish Energy Agency: 36 wave energy converters are in place (1 MW), not yet connected to the grid. The company is further developing a project in Ghana.

Uppsala University got permission to expand their test site in Lysekil. Further, they are involved in the project funded by the European Commission research and innovation programme Horizon 2020 coordinated by Fortum which concerns the demonstration of the Penguin wave energy converter, developed by the Finnish company Wello, to be carried out at Wave Hub in the UK. The EU has granted €17 million. In addition to Fortum, Uppsala University and Wello Ltd, the joint project consists of Mojo Maritime Ltd, Wave Hub Ltd, Green Marine (UK) Ltd, Plymouth University and the University of Exeter.
