The energy company GreatPoint has figured out a way to transform coal into a clean natural gas, and the operation is less costly than drilling for it. The company’s researchers refined a catalytic process developed in the 1970s that also captures the harmful carbon dioxide emissions. The resulting product, called “bluegas,” can flow through pipelines and can be used for all the same applications as the drilled form. The Chicago-based firm plans to expand within the United States and in China.
