Renewable Energy Wave Energy


www.managingwater.co.uk Marine Energy Project


A new project to extract energy from waves using wave energy converters has been unveiled by the Energy Technologies Institute


The ETI has invested around £24m in marine energy with the aim of exploiting the energy potential of the waters from around the UK


The wave energy converter system (WECs) will be designed and built to extract energy from waves and this is expected to begin in Summer 2012.


Offshore wave energy has the potential to be one of the most environmentally benign forms of electricity generation with a minimal visual impact from the shore.


Although wave energy is a form of concentrated wind energy, as it has often travelled over large distances it is regularly out of phase with the local wind conditions. Wave energy can therefore help to balance output variability from other renewable sources and maximise the efficient use of the electricity networks. Wave energy is also more predictable than many other forms of renewable energy, such as wind or solar, and can be forecast accurately up to five days in advance.


Wave energy is clean and renewable! It is one of the last renewable energy forms which mankind has yet to harness, and its potential is huge.


The technical and


economically recoverable resource around the UK alone has been estimated to be between 50-90TWh per year or around 14- 26%[1] of the current UK electricity demand.


Wave energy could play a major part in the world’s efforts to combat climate change, potentially displacing 1 – 2 billion tonnes of CO2 per annum from conventional fossil fuel generating sources. Such installations would also provide many employment opportunities in construction, operations and maintenance. As an indigenous resource that will never run out, wave power would provide the UK with security of supply.


The first phase is a detailed design concept for the wave energy converter system. This needs to be capable of delivering at least 10MW of power and is anticipated to last around 12 months.


The second phase will involve trialling and developing the new system at sea level.


Marine technologies have the potential to play an important role with other offshore renewables, enabling the UK to meet its long-term carbon emission reduction targets.


In its research, the ETI identified cost reduction as

fundamental for the development of the marine energy sector.


ETI chief executive Dr David Clarke warned that the long- term viability of wave energy depends on whether it can compete with other low-carbon energy sources, such as wind power.


He said: "Wave energy offers a potential clean energy source for the UK without needing to import fuel but we need to ensure that it is affordable and competitive with other technologies.


"For wave energy to realise its potential there will need to be reductions in the costs of building, installing and operating the devices and associated infrastructure, as well as improvements to device technical performance and reliability."


The ETI has issued a request for proposals in a bid to encourage organisations to get involved in the project. The deadline for notification of intention to submit a proposal is December 2 and all proposals must be submitted by January 25 2012.

The coastal waters around the UK are among the most regulated and controlled seas in the world with respect to the marine environment. Especially now as we are seeing an increase in offshore activity which includes all forms of renewable energy development. Lubricants and fluids for use offshore have to be formulated in accordance with OSPAR (Oslo Paris) regulations to meet the very highest environmental standards and need to be registered with all of the regulatory bodies involved. These bodies, CEFAS, SODM and KLIMA OG, administer the North Sea, Irish Sea and Norwegian Waters


Areas of Special Scientific Interest and Marine Conservation Zones now require oils that are registered before any form of offshore activity such as oil and gas exploration, wind farm

construction, tidal turbines and wave power generators can begin. PANOLIN has been involved in the offshore market for about 10 years and has a range of registered hydraulic oils called PANOLIN ATLANTIS. In addition PANOLIN ATLANTIS oils are used in Remotely Operated Vehicles, Cranes, Seabed Cable Laying Machines and Subsea Mining Equipment. Operators who want to use these oils can do so in the full confidence that they are certificated which, along with the Material Safety Data, assist with the risk assessments that are carried out before any such work is undertaken.


Original Equipment Manufacturers also offer PANOLIN ATLANTIS oils as factory fill which guarantees full compliance right from the start.
