The two units will operate in conjunction with solar collectors that concentrate the sun’s energy to create heat, which is captured by the ORC units to generate electricity.
For this 5.5MW application in Hawaii, the two Turboden TD 27 HR ORC systems will take heat energy from Sopogy’s MicroCSP solar collectors into a receiver tube that will heat up a transfer fluid to create the high-temperature thermal resource.
The heated fluid then becomes the fuel to power the ORC units, which is said to be the first application of the the company’s ORC systems in this solar-thermal application.
Installation is expected to begin during the fourth quarter of 2011.
With Turboden, Pratt & Whitney offers a spectrum of ORC products ranging in output power from about 280kW to about 10MW of renewable power.
