Power-generating stations worldwide release 12 billion tons of carbon dioxide every year as they burn coal, oil or natural gas; home and commercial heating plants release another 11 billion tons. A team of Dutch scientists has a use for it.
Power plants could, they argue, pump the carbon dioxide through water or other liquids and produce a flow of electrons – and therefore more electricity.
This would be enough, they argue, to create 1,750 terawatt hours of extra electricity annually – about 400 times the output of the Hoover Dam in the Nevada – and all without adding an extra gasp of carbon dioxide into the atmosphere. The exhaust from one cycle of electricity production could be used immediately to deliver another flow of power to the grid.
