It is a complex and expensive process, and many of the schemes proposed in the 1990s have been abandoned as too expensive or too technically difficult.Īn overview of the report says: “The technology still faces many barriers, would only start to deliver too late, would have to be deployed on a massive scale at a scarcely credible rate and has a history of over-promising and under-delivering.”Ĭurrently there are only 26 CCS plants operating globally, capturing about 0.1 per cent of the annual global emissions from fossil fuels. “įossil fuel CCS is a distraction from the growth of renewable energy, storage and energy efficiency that will be critical to rapidly reducing emissions over the next decade.įriends of the Earth, Global Witness Attempts abandoned The CO2 that is removed is converted into a liquid and pumped underground into geological formations that can be sealed for generations to prevent the carbon escaping back into the atmosphere. These include gas and coal-fired electricity generating plants, steel-making, and industries including the conversion of natural gas to hydrogen, so that the gas can then be re-classified as a clean fuel. The report, from Friends of the Earth Scotland and Global Witness, was commissioned by the two groups from researchers at the UK’s Tyndall Centre for Climate Change Research.ĬCS, as the technology is known, is designed to strip out carbon dioxide from the exhaust gases of industrial processes. Instead of financing a technology they can neither develop in time nor make to work as claimed, governments should concentrate on scaling up proven technologies like renewable energies and energy efficiency, it says. One of the key technologies that governments hope will help save the planet from dangerous heating, carbon capture and storage, will not work as planned and is a dangerous distraction, a new report says.
