Advancements in energy generation technology are poised to offer environmentally sustainable alternatives when compared to mid century combustion/steam systems. Using emerging clean energy technologies, coal and other fossil fuel based processes can operate at high efficiencies, be integrated with carbon management platforms, and offer power that is reliable and reasonably priced. To achieve the goals and demands of clean energy, the conditions under which fossil fuels are currently converted into heat and power are extremely harsh compared to previous combustion/steam cycles. Temperatures are reaching 1600 Celsius (C) in certain systems and pressures are reaching as high as 5000 pounds per square inch (psi)/340 atmospheres (atm). These conditions serve as drivers for new harsh environment sensor technology, so that these systems can be safely monitored and efficiently operated. Emerging power systems are also highly integrated with many unit operations leading to a new level of operational complexity especially when the need for cycling the plants for grid management is considered. Process control systems are a key component in managing the complexity of the emerging power systems, but new control technology is needed address complexity and the desire to optimize the integrated process for changing demands.
This paper will highlight the US Department of Energy, Office of Fossil Energy and National Energy Technology Laboratory’s Program in Sensors and Controls which is aimed at addressing the technology development needs and drivers through the development of new sensor materials and designs and novel control architectures.
