Researchers from the Japan Coal Energy Centre and Columbia University have signed a memorandum of understanding with the state of Wyoming to work on technology to make calcium carbonate from carbon dioxide captured from coal-fired power plants and mixed with coal ash and industrial waste. Columbia University and its spin-off GreenOre CleanTech are currently running pilot-scale trials of the technology, and the next step will be the launch of a joint development project, scheduled for early 2020. Following that, the technology is to be deployed at industrial scale at a 400 MW coal-fired power plant in Wyoming, with funding expected both from the Japanese and US governments.
