INTRODUCTION

Ocean Energy Systems (OES) is the short name for the Technology Collaboration Programme on Ocean Energy Systems under the International Energy Agency (IEA). 
 
This Annual Report presents an overview of progress made by the OES, including summaries of new, ongoing and recent projects, as well as updated country reviews prepared by the Delegates. 
 
Interest and outreach for new membership within OES continued in 2018. Australia re-joined the OES in August and the Commonwealth Scientific, and Industrial Research Organisation (CSIURO) signed the Implementing Agreement on behalf of the Australian Government.
 
The OES is always looking for new members across the globe, and key representatives from potential new member countries are encouraged to attend meetings as Observers. 
 
The OES has 25 members, which provide a broad international base of information, sharing experience and knowledge and further a diversified representation of interests: members are from governmental departments, utilities, universities and research organizations, energy agencies and industry associations. This is one of the benefits of joining OES: participants gain an international perspective on ocean energy issues, opportunities and present challenges.
 
The OES international co-operation facilitates:
  • Securing access to advanced R&D teams in the participating countries;
  • Developing a harmonized set of measures and testing protocols for the testing of prototypes; 
  • Reducing national costs by collaborating internationally;
  • Creating valuable international contacts between government, industry and science;
  • Sharing information and networking.  
 
This Executive Summary provides a brief summary of the OES Annual Report for the year 2018. It synthesizes the main achievements in the OES collaborative activities and presents relevant policies, R&D activities and deployments in the water by each OES member country. It also includes, as in previous years, an interview on a specific topic, this year about performance metrics on ocean energy: Two experts from Wave Energy Scotland (WES) and from the U.S. Department of Energy (DOE) are invited to give their views on this topic based on the programmes being run by WES and by the Water Power Technologies Office (WPTO) within DOE where a formalized technology evaluation or stage-gate process is applied to measure the success of the technology and its development.
 
OES has a close link with the International Conference on Ocean Energy (ICOE), held every two years, and leads a competitive process to select host country teams. In 2018, the 7th edition of ICOE was held in France gathering 200 exhibitors and more than 3500 visitors from 36 countries. In this report, OES also interviews the past and current Chair (2020) of the ICOE to hear about the benefits of this event for the international ocean energy industry.
 

 

OES KEY ACHIEVEMENTS IN 2018
The OES held two ExCo Meetings in 2018: The 34th and 35th meetings were convened in Cherbourg, France (14 – 15 June 2018), and in Las Palmas on Canary Islands (29 - 30 November 2018).  The meeting in Cherbourg was organised for the occasion of the International Conference on Ocean Energy (ICOE 2018) and the meeting in Las Palmas was hosted by the Oceanic Platform of Canary Islands (PLOCAN) and organised in the same week as the High-Level Conference of the Atlantic International Research Centre (AIR Centre).

The overall Work Programme of the OES is headed by an Executive Committee composed of representatives from each participating country and organisation, while the management of individual research projects or studies is the responsibility of Operating Agents. The present Programme consists in thirty Tasks, of which ten are currently operational.

During 2018, the OES project on Environmental Issues (known as Annex IV) led by the US Department of Energy (DOE) pursued a process for retiring, or putting aside, environmental risks that continue to slow consenting and hamper the development of marine energies. This process is made up of three parts:

  1. Data Transferability and Data Collection Consistency;
  2. Risk Retirement Pathway;
  3. Outreach and Engagement with the MRE Community.

Tethys, the online knowledge management system, continues to expand and increase user interactions. Last year, the publicly available collection of scientific papers, reports, and other media increased by 681 papers  for a total of 4,723 entries. During 2018, a peer review process was completed for Tethys with feedback from the greater Tethys community online. Two workshops were organised: one on social and economic data to address consenting; and a second one on the data transferability and data collection consistency processes. Further 3 webinars were hosted during 2018. Annex IV  continued to collect and update information on new wave and tidal projects as well as on-going research studies. 

On the Cost of Energy for Ocean Energy Technology, further progress has been done during the year with a new study led by Tecnalia from Spain as a continuation of a previous one done in 2015. This new study monitors the evolution of ocean energy costs and assesses the impact of different drivers on the LCOE, by taking into account historical trends, future development and differences among technologies and countries. 

OES has two tasks dedicated to the modelling verification and validation, one led by Ramboll, for wave energy, and a second one, for tidal energy, led by the Energy Research Institute at Nanyang Technological University. These groups have been engaging with a number of experts from universities, research institutions and companies and comparing results among different numerical codes.  
A group of member countries – Japan, India, China, Korea, France and The Netherlands – have been working together on OTEC to assess the potential around the world and discuss the present status and plans for OTEC projects.

OES has been developing efforts on the topic of international performance evaluation of ocean energy technologies with strong inputs from the European Commission, the U.S. Department of Energy and from Wave Energy Scotland, aiming to support the definition of a fully defined set of metrics and success thresholds for wave energy technologies and develop an internationally accepted approach. 

In 2018, OES supported the organisation of a second workshop on ocean energy in insular conditions, aiming to discuss barriers and opportunities, and also supported a workshop on open water testing to exchange information and experience on all aspects of planning, development and operation of open-water test facilities.

The need to assess the number of jobs related to the development of the ocean energy sector has been discussed and the terms of reference to prepare this study was prepared, with the work expected to start in 2019.

  • Tidal stream projects made significant strides in demonstrating performance and reliability:
     
    • SIMEC Atlantis Energy’s MeyGen array project in Scotland’s Pentland Firth surpassed 10 GWh of generation onto the grid by December 2018. The next phase, planned for late 2019, is to install an additional two Atlantis turbines uprated to 2MW each. 
       
    • The Nova Innovation three-turbine 0.3 MW array has continued to operate and further granted an extension to their existing seabed lease to increase capacity from 500 kW to 2 MW. This extension will enable the installation of three additional turbines, each rated at 100 kW, thus increasing the number of turbines in the water from three to six.
       
    • Orbital Marine Power continued testing their 2 MW twin rotor floating tidal turbine at the site and in 12 months of continuous operation achieved 3 GWh of generation. The company will design and build their optimised production model, for deployment at EMEC in 2020. 
       
    • The Swedish tidal developer Minesto built and deployed their commercial scale DeepGreen500 tidal kite off Holyhead, North Wales. Other tidal current projects are further planned to be tested next years at EMEC and include the Instream Energy Systems’s 100 kW floating tidal device with funding from Innovate UK’s Industrial Strategy Challenge Fund, the Magallanes Renovables’s 2 MW floating tidal device and the Tocardo floating platform intended to provide a generic solution for the integration of tidal turbines.
       
  • Wave energy projects are progressing in UK waters:
     
    • Wello Oy marked its first year of deployment of Penguin at EMEC’s Billia Croo test site and the next generation of the device is planned be relocated to EMEC, next to the existing one, after testing in Estonia.
       
    • CorPower deployed their half-scale C3 device and demonstrated 18 months of combined dry and ocean testing at EMEC.
       
    • Marine Power Systems (MPS) built their 10 kW WaveSub device in Pembroke Dock and are currently finalising tests in FaBTest, Cornwall. 
       
    • The Australian wave energy developer Bombora Wavepower secured a £10.3 million ERDF grant to test a 1.5 MW prototype at Pembrokeshire.
       
    • Laminaria’s 200 kW LAMWEC device is planned to be deployed at EMEC in 2019. 
 
 
THE UNITED STATES
  • The U.S. Department of Energy's Water Power Technologies Office (WPTO) has maintained an upward trend since 2013, and in 2018 the annual budget was at $105 million, a 25% increase from 2017 and its highest level ever. 
     
  • The Naval Facilities Engineering (NAVFAC) is funding and actively managing the Navy's Wave Energy Test Site (WETS) in Hawaii with a budget of $35 million to support Alternative and Renewable Energy R&D. 
     
  • In April 2018, a recent funding opportunity was announced of up to $23 million to support marine energy technologies.
     
  • In June 2018, the six awardees selected to receive a total of $6.7 million in federal funding have been announced: The Igiugig Village Council (IVC) in Alaska, the Ocean Renewable Power Company, Resolute Marine Energy, Oscilla Power, Enorasy and the University of Alaska.
     
  • During 2018, WPTO collected public comments on its draft report “Potential Maritime Markets for Marine and Hydrokinetic Technologies” that details economic and technical landscapes of 14 different non grid markets for marine energy technologies. The final report will be released in 2019. 
     
  • Several teams have been engaged in developing innovative products and systems with improvements on control or cost reduction: The ocean energy research team at NREL conceived and patented an innovative wave converter concept; SNL completed wave tank testing work in advanced wave energy dynamics and controls.
     
  • On environmental issues, two relevant initiatives are pointed out: (1) the new sensor package, NoiseSpotter, developed by a research group from Integral Consulting, Inc. in collaboration with PNNL, designed to record sound generated by marine energy devices and (2) the Living Bridge Project, led by the University of New Hampshire, where the Memorial Bridge has been converted into a demonstration "smart bridge" equipped with environmental sensors powered by a 25 kW cross-flow vertical axis tidal turbine supplied by New Energy Corporation of Calgary, Alberta.
     
  • The 1 MW OE Buoy developed by Ocean Energy USA (originally from Ireland) has been under construction in Oregon and once complete will be towed to the U.S. Navy’s WETS in Hawaii for testing. The BOLT Lifesaver wave energy device from the Norwegian company Fred Olsen was also redeployed in this testing facility.

OPEN SEA TEST SITES

There are many open sea test sites established across the world and each has its own challenges, such as consenting issues, resource and operating environments. Test centres also provide very different service offerings to industry. 

The development of open sea testing facilities encourages ocean energy development by enabling practical experience of installation, operation, maintenance and decommissioning activities for prototypes and farms, as well as on services and streamlining procedures.
