Moreover, during this period, he expected carbon capture and storage technology to become cost-effective, thus helping to reduce or eliminate emissions from gas power stations.

BBC: Coal-to-gas power shift 'to cut energy costs'

The carbon capture and storage technology can strip carbon from fossil fuel exhaust gases and store it in rocks, but it is unproven at scale, trials are years behind schedule and it may not work in some areas of the world.

Success with shale gas will reduce dependence on imports and increase tax revenues, they say, but there is a downside: if it takes off, shale gas will shatter the UK's statutory climate change targets unless the government moves much faster with carbon capture and storage technology.

BBC: UK shale gas bonanza 'not assured'

The Liberal Democrat MSP said that initially the power station was to have 400 megawatt of its gross output (300 megawatt net) processed through carbon capture and storage technology, which would leave 75% to 80% of the plant' s CO2 emissions unabated for an indeterminate length of time.

Longannet was the trial site for carbon capture and storage, a technology that is yet to be proven commercially, but funding for that was withdrawn by the UK Government last October.

He has batted away all criticisms of the Albertan tar sands, where oil extraction is an especially dirty business, and placed his faith in carbon capture and storage, an unproven and expensive technology.

Ayrshire Power wants to build a plant with experimental carbon capture and storage (CCS) technology at the site.

Only coal plants with carbon capture and storage will, in effect, be allowed, although this technology is unproven on a large scale.

BBC: Energy bill to boost cleaner energy production

So today I'm announcing a Carbon Capture and Storage Task Force that will be charged with the goal of figuring out how we can deploy affordable clean coal technology on a widespread scale within 10 years.

The bill also sets rules for building more natural-gas storage (as imports replace dwindling domestic supplies) and for developing technology to capture and sequester carbon emissions from fossil-fuel plants.
