Peterhead represents the best hope for the first "clean power" station in the UK and potentially Europe, the power company behind the scheme has said.

Scottish & Southern Energy (SSE) said the plant could be up and running within five years in response to the UK Government's launch of a £1 billion competition to build a carbon capture and storage (CCS) power station for the third time in five years.

UK ministers also announced that Edinburgh University will host a new £13 million CCS research centre.

However, Scottish ministers called on the Tory-LibDem Coalition to prove its commitment to the technology, following previous false starts.

Labour also accused the Coalition of appearing to quietly drop a commitment to get a total of four such plants off the ground by 2020. Earlier this year it was announced that plans for the first CCS power station plant to be built at ScottishPower's coal plant at Longannet, in Fife, were to be scrapped, prompting a cross-border row.

Last night, business leaders warned that, if it was to work, the latest funding competition had to learn the lesson of past failures.

CCS technology has been praised for offering the potential to safely dispose of harmful carbon by burying it underground, but it has yet to be proven to work on a commercial scale.

The Peterhead development, part of a co-operation between SSE and Shell, is competing with a number of other projects across the UK for what experts say is vital Government backing.

Paul Smith, from SSE, said: "For more than six years, we've thought that Peterhead represents the best site in the UK for a gas CCS project.

"Our co-operation with Shell strengthens this proposition even further. The Peterhead project is in a strong competitive position and can proceed at a pace at least equal to other CCS projects in Europe."

Companies have until July to submit a bid, with a decision expected in the autumn. Projects will have to be up and running between 2016 and 2020.
