アルストム Alstom、潮流発電の Tidal Generation Limited (TGL) 社をロールスロイス社から取得

　フランスの発電事業などを手がけるアルストム Alstomは、潮流発電の Tidal Generation Limited (TGL) 社をロールスロイス社から取得したと発表しました。潮流発電の Tidal Generation Limited (TGL) 社は、スコットランドの欧州海洋エネルギーセンター　European Marine Energy Centre (EMEC) の海洋エネルギー開発用のテストサイトにおいて、2010年9月より500kWの潮流発電装置のテストを行い。合計100MWhの発電を行い、同センターの行った初めての商用電源網への連系の初めてのケースとなった実績をもっています。このEuropean Marine Energy Centre (EMEC)での実証実験は、今後1MW機の開発へと駒を進める予定です。これにより、本格的な潮流発電機の開発へとつなげることが期待されています。

　海底で巨大なプロペラを回す潮流発電機に関しては、その実現性について若干の疑問を持っていましたが、今回の Tidal Generation Limited (TGL) 社のものは、一定の実証も済ませ、さらに大型の実証機を稼動させる段階に到達しています。
　さらにフランスの発電、送電、鉄道インフラの世界で大企業たる地位を確保しているアルストム傘下に加わったということは、潮流発電に積極的な発言が目立ち始めたフランスの海洋エネルギー開発において、その活躍が期待され、これまでの動きが評価されているということですから、1MW機の実証試験への興味が湧いてきます。

プレスリリース / Tidal Generation Limited,25 September 2012
・Rolls-Royce, the global power-systems company, today announced the sale of Tidal Generation Limited (TGL) to Alstom

"・Innovative Tidal Stream Power Generation Project First to Supply 100MWh to Scottish Grid
・Demonstrates Rolls-Royce Commitment to Developing Next Generation of Cleaner Energy Solutions

Rolls-Royce, the global power systems company, has achieved a significant milestone in the deployment of tidal energy technology with confirmation that its prototype tidal turbine, located subsea off the Orkney Islands, Scotland, has successfully generated and fed over 100 megawatt hours (MWh) of electrical power into the national grid.

Harnessing the reliable and predictable energy of tidal streams, the 500 kilowatt (kW) tidal turbine prototype was designed and built by Rolls-Royce wholly owned subsidiary Tidal Generation Limited.

Robert Stevenson, Rolls-Royce, Vice-President – Power Ventures said: “Rolls-Royce has injected its world-class engineering expertise and incubation processes to deliver this innovative renewable energy project. Reaching the 100 megawatt hours milestone highlights the significant potential of cleaner, greener tidal power as part of a diversified UK energy mix. Having proven the capability of tidal energy, Rolls-Royce is well placed to meet any future demand with larger, more efficient technology on a commercial scale.”

As a reliable and predictable energy source, deep water tidal stream power generation could make a valuable contribution to meeting the electricity demands and carbon emissions reduction objectives of many industrialised nations, including the UK, Canada, Australia and the U.S.A. For example, Rolls-Royce tidal technology could generate up to 30TWh (terawatt-hours) of UK electricity, equivalent to around 7.5 per cent of existing UK electricity needs or enough to power 3 million homes.

Harnessing the Energy of Tidal Streams

　Installed as part of the Deep-Gen III project, co-funded by the UK government-backed Technology Strategy Board, the Rolls-Royce prototype tidal turbine is currently deployed at the European Marine Energy Centre’s (EMEC) offshore test site off the Orkney Islands, Scotland. It is the first EMEC located project to both receive Renewable Obligation Certificates and to reach 100 MWh of supply to the grid.

The tidal unit’s three-bladed turbine is attached by a tripod to the seabed and can operate, fully submerged at water depth of 40 meters. Its innovative design allows the turbine to continually rotate to face the incoming tide at an optimal angle. In addition, the turbine unit is semi-buoyant and can be easily towed to and from the point of operation, minimising installation and maintenance costs by avoiding the need for specialist vessels.

Neil Morgan, Head of Energy at the Technology Strategy Board said: “This is a significant milestone for the UK marine renewables industry. The UK is well-placed to exploit tidal stream energy resources and, if commercialised on a large scale, this technology could be an important part of the renewable energy mix we’ll need in the future, and could create jobs and exports for the UK.”

As part of the Energy Technologies Institute funded ReDAPT (Reliable Data Acquisition Platform for Tidal) consortium project, Rolls-Royce is currently building a 1MW tidal turbine demonstration unit that will be deployed in mid-2012 at EMEC in Orkney. The project will deliver detailed environmental and performance information never before achieved at this scale in real sea conditions. Rolls-Royce is also working with a number of developers in advancing demonstration arrays, systematic arrangements of turbines, which will lead to large scale commercial deployment.

-----image(上-”Tidal turbine installation”、下２点も) : 上記リリースより-----

"Alstom has signed an agreement with Rolls-Royce to acquire Tidal Generation Limited (TGL), a wholly owned subsidiary of Rolls-Royce Plc, specialised in the design and manufacture of tidal stream turbines. Alstom’s acquisition of TGL is expected to be completed within the next few months, subject to closing conditions.
TGL is at the forefront in the design, development and manufacture of tidal stream turbines which capture and convert the energy of tidal streams to generate electrical power. TGL’s first 500kWe unit was successfully installed at the European Marine Energy Centre (EMEC) at Orkney in Scotland. It generated and fed into the grid over 250MWh of electricity – enough power to supply the equivalent of 300 homes - averaging 12 hours of operation each day.

This acquisition reinforces Alstom’s position in renewable power as the company with the broadest and most complete range of products and systems, from hydro to wind, geothermal, biomass and solar. It will complement Alstom’s on-going research and development activities on ocean energies that are based in Nantes, France. It gives Alstom the opportunity to build a complete portfolio of tidal products and technologies which is necessary to cover the wide range of site conditions and to meet all customer needs.

TGL, which is based in Bristol, UK and employs 29 people, will benefit from Alstom’s experience in the energy industry, its global presence in 100 countries and its integrated offer including power generation and transmission.

TGL was the first EMEC located project to receive UK Renewable Obligations Certificate. As part of the Energy Technologies Institute commissioned and co-funded ReDAPT (Reliable Data Acquisition Platform for Tidal) consortium project, TGL’s 1MW tidal turbine will be installed in EMEC’s water by the end of 2012 and will be tested in various operational conditions off Orkney over a two-year period. Detailed environmental and tidal stream information will be measured to help the marine renewable industry understand the challenges that must be addressed for tidal technology to be developed on a commercial scale.

“With this acquisition, Alstom strengthens its position in a promising market and complements an already large offer of cutting-edge renewable energy technologies” said Jérôme Pécresse, President of Alstom Renewable Power. “This new step sets Alstom as a leader in ocean energies, with its Haliade™ 150 offshore wind turbine and its stake in AWS Ocean Energy Ltd, Scotland’s pioneering company in the wave energy, with whom we will provide wave devices for the world's largest wave farm off the coast of Orkney in Scotland. We now intend to be rapidly in a position to participate to pilot farms projects and develop a tidal turbine commercial offer” added Jérôme Pécresse.
