Jeffrey Phillips, a Senior Program Manager at the Electric Power Research Institute (EPRI), provided an overview of the U.S. Dept. of Energy's and Ohio Coal Development Office's Advanced Ultrasupercritical Boiler and Steam Turbine Materials Development Program. This is a $50 million, 9-year effort aimed at increasing steam temperatures by more than 250°F above the current state-of-the-art. This remarkable effort has now resulted in a code case submission to the ASME Boiler Code committee for a new material which can operate at the targeted conditions. Approval of this material will open the door to the most significant improvement in the thermodynamic performance of coal-fired power plants in 50 years. You can learn more about this at an April 7 conference also covered in this Alert. One of the important discussions following the talk was regarding the possibility to design new coal-fired boilers to eventually operate in the advanced ultrasupercritical state but to initially operate at efficiencies substantially higher than the old power plants they replace. So the old plants could be immediately replaced with major benefits. Then in 2020 when the advanced ultrasupercritical materials are commercial, the plants can be retrofitted for this additional efficiency boost. Click Here For Complete Presentation Text
