THE PRIMARY OBJECTIVE OF THE 3-YEAR PROJECT IS TO DESIGN, DEVELOP, AND PERFORM A FIELD DEMONSTRATION OF A ZERO GREENHOUSE GAS (GHG) EMISSION COMBINED COOLING, HEATING, AND POWER SYSTEM (CCHP). THE TECHNOLOGY CAN USE GREEN HYDROGEN OR RENEWABLE PROPANE TO ENHANCE FLEXIBILITY AND RESILIENCY DURING GRID OUTAGES. THE COMBINED UNIT WILL ENHANCE THE PENETRATION OF SOLAR AND GEOTHERMAL RENEWABLE ENERGY SOURCES IN DISTRICT ENERGY (DE) SYSTEMS TO BROADLY CONTRIBUTE TO NATIONWIDE DECARBONIZATION EFFORTS. THE FIELD TEST WILL BE CONDUCTED WITH A REDUCED SCALE, FLEXIBLE FUEL ENGINE TO LEVERAGE EXISTING RESOURCES AT CSU. THE GOAL OF BUDGET PERIOD 1 IS TO PERFORM DETAILED (TECHNICAL, ECONOMIC, SYSTEM) DESIGN STUDIES FOR THE PROPOSED SYSTEM AND VERIFY DISTRICT ENERGY AND FLEXIBLE CHP PERFORMANCE TARGETS CAN BE MET. THE OBJECTIVE FOR BUDGET PERIOD 2 IS TO INTEGRATE THE ENGINE AND THE TURBO-COMPRESSION COOLING SYSTEM AND PERFORM LABORATORY EXPERIMENTAL TESTING TO PREPARE FOR A FIELD DEMONSTRATION. FINALLY, THE PRIMARY OBJECTIVE FOR BUDGET PERIOD 3 IS TO PERFORM A FIELD TEST OF THE INTEGRATED CCHP SYSTEM AND VERIFY THE TECHNOECONOMIC PERFORMANCE TARGETS ARE MET.
