Abstract : The Infinia PowerDish Combined Heat and Power (CHP) demonstration was intended to showcase and assess the capabilities of the Infinia PowerDish CHP technology to generate clean solar electricity as well as thermal energy for domestic hot water and space heat requirements. When applied to Department of Defense (DoD) facilities, at both domestic facilities and forward operating bases (FOB), the PowerDish CHP could reduce the consumption of utility electricity and fossil fuels, thus reducing air and carbon emission pollution as well as stabilizing or even reducing total energy costs for the application site. An alternative to the PowerDish CHP technology for providing non-fossil fuel electric generation and thermal energy for end-use application would be to install two systems: a photovoltaic (PV) system for electricity and a solar thermal system for water and space heating applications. Each of the specific performance objectives was addressed in the demonstration which included: monitoring estimated facility energy usage; maximizing renewable energy usage; maximizing savings for systems economics; minimize direct greenhouse gas (GHG) emissions; monitoring facility metering; monitoring system maintenance; and monitoring system integration. Overall, the demonstration clearly confirmed that the PowerDish CHP technology can provide clean solar electricity as well as thermal energy for water and space heating applications. However, while the amount of electric production was somewhat less than expected, the quantity of thermal energy delivered to the facility for end-use applications was significantly lower than expected. This report and the Final Report detail the reasons for the thermal energy underperformance as well as the lessons learned and performance improvements gleaned from this demonstration. The PowerDish CHP system is a modified Infinia PowerDish solar system.
