46 02 MARKET AND INDUSTRY TRENDS few years; most of these developments are planned for U.K. coastal waters. Scotland awarded approval to MeyGen Ltd. (U.K.), now fully owned by Atlantis Resources Ltd. (Singapore), for the 86 MW first phase of what could eventually be a 398 MW tidal array in the Inner Sound of Pentland Firth. MeyGen plans to start with a demonstration of six turbines, with construction commencing in 2014.6 Consent was also granted for a 40 MW (40–50 device) wave farm off the coast of Lewis, Scotland, which is considered one of the best wave energy locations in Europe. The deployment of Aquamarine Power’s (Scotland) Oyster wave energy devices will take place in the coming years, alongside necessary grid interconnection.7 In March 2014, the U.K. government accepted an application for the proposed 240 MW Swansea Bay Tidal Lagoon, advancing this concept closer to realisation.8 Construction is planned for the period 2015–2018.9 Meanwhile, the proposed Severn Barrage in Wales (U.K.), which might provide 5% of the U.K.’s electricity demand if built, was dealt a heavy blow when a parliamentary committee said that the project should not go ahead as presented because it had not yet demonstrated evidence of economic, environmental, and technological viability.10 Another potential 240 MW tidal project, proposed for the Alaska coast (United States), was granted a preliminary permit extension in early 2014, for the purpose of establishing project feasibility.11 ■■OCEAN ENERGY INDUSTRY Ocean energy technologies continued to advance during 2013, with a wide variety of devices under development. Industry firms advanced their goals through acquisitions and collaborative agreements, and governments often lent a hand. Scotland’s EMEC, the world’s leading test facility for wave and tidal energy converters, continued to share its expertise globally during 2013. It announced an agreement to help set up a test facility in Singapore—the latest of several agreements with parties across North America and Asia.12 In addition, neighbouring Ireland recently launched its Offshore Renewable Energy Development Plan, committing funds for test facilities, R&D, and a feed-in tariff for ocean power.13 (See Policy Landscape section.) Alstom started the year by completing the acquisition of Tidal Generation Limited from Rolls-Royce Holdings plc.14 By an agreement between Alstom and ScottishPower Renewables (Scotland), which is owned by Iberdrola (Spain), four of Alstom’s 1 MW tidal turbines will be deployed at the planned Sound of Islay array, beginning in late 2015.15 In late 2013, Voith Hydro acquired the remaining 20% share of Voith Hydro Ocean Current Technologies from Innogy Venture Capital.16 As noted above, both companies launched turbines at EMEC in 2013. Voith’s HyTide turbine has a direct drive (no gears), uses symmetrical blades for bi-directional operation, and relies on sea water lubrication, all for simplicity and robustness in the harsh marine environment.17 Unlike the HyTide, which has a fixed nacelle and blades, Alstom’s turbine has adjustable nacelle position and blade pitch for maximum energy potential.18 Atlantis Resources Ltd, developer of the AR1000 1 MW tidal turbine, raised capital in its initial public offering in early 2014 and received additional funding from the European Commission.19 Atlantis plans to use the funds to advance the MeyGen project, including the AR1500 turbine developed with Lockheed Martin (United States), and to fund its AR1000 demonstration project in China. Atlantis acquired all remaining shares in MeyGen Ltd from GDF Suez (France) and Morgan Stanley (United States) in October.20 In early 2013, DCNS (France) acquired a majority stake in OpenHydro (Ireland), which continued to test new versions of its open-center tidal turbine at EMEC.21 Later in the year, DCNS announced an agreement with Fortum and AW-Energy (both Finland) to develop a 1.5 MW wave power demonstration project in Brittany, France, using AW-Energy’s WaveRoller device.22 In September 2013, the French government issued tenders for pilot tidal projects off the coast of France.23 Both DCNS and GDF Suez have expressed interest in the projects, the latter possibly joining forces with Voith and Alstom for their tidal turbines.24 Aquamarine Power continued testing of its second Oyster 800 wave energy device at EMEC, and Pelamis Wave Power (Scotland) continued to develop its articulating cylindrical wave energy converter.25 Pelamis tested new scale models in 2013, with the aim of improving power, reliability, and economics of the device through changes in configuration, shape, and controls.26 In partnership with the University of Dundee, Pelamis is investigating the advantages of utilizing concrete, in place of steel, as the main construction material for its device, for improved design options and economics.27 Vattenfall (Sweden) intends to start testing of the latest Pelamis device at EMEC in 2014.28 Wello Ltd (Finland) redeployed its Penguin wave energy converter at Orkney in July 2013. The device fully encapsulates a rotating eccentric mass that is actuated by waves, driving a generator typically used in wind turbines.29 Seatricity (U.K.), another relatively new wave technology company, is poised to develop a 10 MW array of its Oceanus 2—a buoy-type device that pumps seawater onshore for power generation—at the Wave Hub test facility in Cornwall (U.K.).30 Minesto (Sweden) started tests in Ireland of a 1:4 scale prototype of its Deep Green tidal device, which it describes as an underwater kite that is designed to work well in low-velocity currents. Deep Green marries a turbine with a wing and a tether, capturing tidal energy while looping tangentially to the direction of the tide. A full-scale device is to be deployed by 2015.31 China announced funding for ocean energy technology in 2013, including a 200 kW turbine developed by Harbin Engineering University, as part of a plan to use ocean energy to improve sustainability of remote islands.32 Other Chinese pilot projects launched in late 2012 and 2013 included wave energy converters developed by Guangzhou Institute of Energy Conversion, and a 120 kW wave buoy developed by Shandong University.33 In early 2014, the European Commission launched a two-step action plan to support ocean energy in Europe.34 The first step was the launch of the Ocean Energy Forum in April, with the aim of bringing together a wide range of stakeholders to find solutions to issues challenging the industry.35
