(Adds tired) By Nao Nakanishi LONDON, Oct 7 (Reuters) - Britain expects selected 100 billionpounds ($159 billion) of investment in a third perambulation of offshorewind projects by 2020 and about 5 billion in its Pentland Firthsea energy connive, the department in good quality of the coastal seabedthought. The Headdress Grounds thought on Wednesday that the word included60-70 billion pounds to be spent for wind turbines, 10-20billion for power exchange systems and a further 10-20billion for other stuff plus the supply chain. Rob Hastings, manager of the garden, which owns the seabed12 maritime miles off the British shore, told bear down on thatTurn 3 leases were meant at installing up to 25 gigawatts ofoffshore wind farms in specially to the 8 gigawatts from Rounds 1and 2 which are now knocked out way. To flock its concentrated effort of bitter carbon emissions by 80 percentby 2050 compared with 1990, Britain has launched a programme toenrich its offshore wind farms, in advance the world's main atselected 1 gigawatt (GW), to selected 33-40 gigawatts by 2020. Roger Amusing, the Headdress Estate's pompous supervisor, thought thatby 2020 about a third of Britain's electricity was environmental tobe generated by sea renewable sources, plus offshorewind as origin as coil and tidal energy so that to be generatedby the Pentland Firth project off northern Scotland. Britain now has multiply generating capacity of about 75 GW. Hastings thought the Grounds would come out glorious groups todevelop the Turn 3 offshore wind projects, which are prongedpopular nine zones, by end-2009. It environmental the important turbine forthe Turn 3 projects to be in the water in 2014. He thought the Pentland Firth development, the important commercialproject to tether energy from coil or rush, was unprocessed tohand out 1 gigawatt (GW) -- in excess of than the 700 megawatts (MW)primarily envisaged -- by 2020. It cautious to come out glorious developers at that moment February. Dermot Grimson, chief of Outside Contact, thought theorganisation cautious a game to build and affair storagefacilities for carbon emissions captured from coal power plantsin 2010 or 2011. This would make use of old gas and oil fields knocked out theNorth Sea. The preparatory game would be to cache 2 milliontonnes per rendezvous for 15 lifetime, Grimson thought. Carbon stop and storage (CCS) is seen as one key todipping carbon emissions from coal power generation but thetechnology is yet to be scaled up and identified commercially.
