CALM Initiative Managing Director, Chris Hardin, is working closely with GTR-M, and its CEO Norbert Hector to develop the technical details for GTR-M’s patented method that utilizes coal combustion residuals (CCRs) to store energy. Last week (January 8 - 12, 2018) Chris toured the Power South CAES plant in McIntosh, Alabama to obtained site specific details on the compressed generator and a variety of technical details. More to come in the near future.
