The UK’s waterways and coastal regions look set to become major sources of renewable energy as the the UK steps up inestment in marine and hydro energy.


Tidal Energy


The UK has the best wave and tidal resource in Europe, an asset that has the potential to provide a considerable proportion of the UK power market in years to come.


Marine energy can be generated from wave power, tidal stream or from tidal range. Tidal Range technologies are considered to be ‘mature’ whilst wave and tidal stream technologies are at an early stage of development, but all are considered to offer the potential for bulk electricity generation. Around 4MW of single wave and tidal stream prototypes are currently being tested in the UK and a variety of sources suggest there is a wide range of possible wave and tidal stream deployment scenarios beyond 2020.


To date, UK Government support for wave and tidal stream technologies has mainly been in the form of grants, with over £100m of funding. This has reflected the early stage of development of wave and tidal stream technologies and the potential for their future deployment.


DECC’s £22m Marine Renewables Proving Fund has taken six of the leading device


developers to a point where they are ready to test full-scale prototypes in the marine


environment. Full-scale prototypes need to be deployed in small arrays before moving to commercial-scale, however, this route to commercialisation is very expensive and risky to those developing devices.


It is only recently, with the development of promising near-megawatt scale devices, that major industrial players have begun to invest in the sector. Whilst larger investors are taking more interest, financial modelling carried out by DECC has shown that the first demonstration arrays (ranging in size from 5 to 10MW) will require both grant and market instrument support to generate the internal rates of return which will be necessary to justify investment from funding partners such as utilities and large industrial organisations.


Recent figures published by RenewableUK suggest that by 2035 the marine energy industry in the UK could employ 19,500 people and bring an annual value of £6.1bn

Marine Current Turbines Ltd (MCT) has been involved with tidal energy technology development since the early 1990’s, initially with the Loch Linhe turbine, then SeaFlow located near Lynmouth, North Devon and more recently Strangford Lough in Northern Ireland where MCT installed SeaGen, the first commercially operating tidal turbine in 2008 (Sea Generation).


The next stage in the development of the SeaGen technology is to install an array of devices. The Skerries site off the north west coast of Anglesey was identified as a possible site for a 10MW array of SeaGen devices


and a newly created development company, Sea- Generation (Wales) Ltd, was set up in 2008 as a joint venture between MCT and RWE npower renewables to take forward the development phase of the project. The project, named the Skerries Tidal Stream Array, has also benefited from funding from the Welsh European Funding Office.


The location for the proposed array is in the Sound between the group of rocks and islands known as the Skerries and Carmel Head on mainland Anglesey, less than 1km from the Anglesey coast, in approximately 20 to 40m water depth. The proposed array will


consist of up to 9 SeaGen devices and have a total capacity of up to 10MW.


It is proposed that the turbine array will be installed and operated for up to 25 years, where it will serve as a test case for the development of the technology as part of a programme of further multiple unit arrays. see www.seagenwales.co.uk
