Technology Profile
Primary Organization Ocean Engineering and Energy Systems

Technology Description Kalina Cycle The Kalina Cycle is a variation of the more conventional closed cycle OTEC system incorporating aqueous ammonia ammonia water mixture as the working fluid instead of the conventional ammonia or propylene working fluid employed in earlier designs of closed cycle OTEC power systems The Kalina Cycle is a break through technology for OTEC power systems providing a nearly 80 increase in efficiency over previous closed cycle designs Because the ammonia water concentrations can be varied throughout the system to optimize according to system temperatures sort of a designer working fluid and by adding an extra component the recuperator heat losses generally experienced in other closed cycle designs can be minimized and recovered thereby improving the overall efficiency of the power cycle
