New cash to fund research into lowering the costs of capturing carbon dioxide from power plants has been announced by the United States.
Its Department of Energy (DOE) is awarding $84 million (£52.3m) to 18 projects in a bid to limit emissions from new and existing coal-fired power plants.
Projects being funded include $12.8 million (£8m) to test carbon capture technology for use in commercial projects such as enhanced oil recovery and $8 million (£5m) to improve the efficiency of getting power from coal.
US Energy Secretary Ernest Moniz said: “The projects announced will focus on the next generation of carbon capture technologies – helping to drive down the cost, increase efficiency and ensure America’s continued international leadership in combating climate change.”
Coal and other fossil fuels still provide 80% of the energy in the US. The Obama Administration has invested $6 billion (£3.7bn) in clean coal technologies to date.
Last month the DOE announced grants totalling $60 million (£37.2m) to drive affordable and efficient PV technologies.
