Kotzebue Electric Association Waste Heat Recovery & Power Renewable Energy Fund Grant November 10th 2008 The thermal energy source for the APC will be the engine jacket cooling system. The heat in the 50/50 glycol/water mix after cycling through the engine radiator, after cooler, and exhaust stack heat will pass through the APC. The cooling supply for the APC will be provided in the winter by the city water system and a 1 MW air cooler. In the summer the cooling will be provided by the existing BAC evaporative cooler. This will increase efficiency and optimize operational time. One of the city’s water loops is routed through the KEA power plant. This system extracts heat from the jacket water system to maintain the city loop potable water. This system is currently used during the winter months to keep the four city water loops at approximately 65 F from approximately November – April. KEA will work with the city to utilize the water system in the summer months to act as the heat sink for the APC generation system. Winter time temperatures are often sub zero so there will be no difficultly generating the necessary temperature differential. KEA’s existing generators can produce an average of 14.5 kWh per gallon of diesel. As of August 2008, KEA purchased diesel at $4.37/gallon. Energy Concept’s Absorption Power Cycle is capable of producing a net 162 kW. Assuming an availability of 95% one APC would produce 1,348MWh which could save approximately 93,000 gallons of fuel per year. This would equate to an annual savings of $406,410. The APC requires a thermal input of 1800 kWth (6.14 MMBtu/hr) for optimum efficiency. There is sufficient thermal energy in KEA’s existing system which produces around 60,000 MMBtu/year, while KEA currently uses only 13,001 MMBtus/year.

Even during periods of peak wind the diesel generators rarely produce less than 1500 kW. The below graph shows there is less than 100 hours/year when the city load is less than 1500 kW. 3 Jacket water calculation based on theoretical calculations. 4 Stack heat calculations based on modeling provided by Cain Industries.
