Robust Combined Heat and Hybrid Power (CHHP) for High Electrical Efficiency Cogeneration

The goal of this project is to develop a hybrid solid oxide fuel cell/gas turbine (SOFC/GT) cycle as a CHHP system for both robust and high P/H cogeneration. The system concept will entail a “direct” hybrid arrangement wherein a high temperature SOFC stack will be inserted within the pressurized side of a recuperative Brayton cycle. Fuel (e.g., methane from natural gas) will be reformed and then primarily oxidized in an electrochemical manner for direct power generation, while residual reformate and byproduct thermal energy will flow into a “bottoming” post-combustion turbine assembly for additional power generation.
