Abstract: A heavy-duty vehicle (1) comprises an ORC system for waste heat recovery out of flue gas exhausted by the vehicle's combustion engine. The ORC system comprises a condenser (3) which is arranged in the slipstream of the vehicle's base structure (7). The overall width W of the condenser is in the range between 1.0 m and 3.0 m, the overall height H of the condenser is in the range between 1.0 m and 4.0 m, while the overall depth D of the condenser is in the range between 0.05W and 0.30W and in the range between 0.05H and 0.30H. Air-intake and air- outlet openings of the condenser are configured for realizing buoyancy flow of environmental air through the condenser. Thanks to the condenser's location, dimensions and configuration considerable improvements in energy savings are obtained as compared to previously proposed ORC systems for heavy-duty vehicles.

Abstract: A method and apparatus of generating electric power includes expanding a flow of exhaust gas from a combustion process as the exhaust gas passes through a turbo-expander disposed on a turbo-crankshaft. The flow of exhaust gas from the turbo-expander is routed through an absorber section of an open cycle absorption chiller system. Water from the exhaust gas is absorbed via a first refrigerant solution disposed in the absorber section as the exhaust gas passes through the first refrigerant solution and out of the absorber section. The flow of exhaust gas from the absorber section is compressed as the exhaust gas passes through a turbo-compressor disposed on the turbo-crankshaft. Electrical power is generated from a bottoming cycle generator disposed on the turbo-crankshaft.

Abstract: Aspects of the present disclosure include a system for turbo-compression cooling. The system may be aboard a marine vessel. The system includes a power cycle and a cooling cycle. The power cycle includes a first working fluid, a waste heat boiler configured to evaporate the working fluid, a turbine, and a condenser. The condenser condenses the working fluid to a saturated or subcooled liquid. The cooling cycle includes a second working fluid, a first compressor configured to increase the pressure of the second working fluid, a condenser configured to condense the second working fluid to a saturated or subcooled liquid after exiting the first compressor, an expansion valve, and an evaporator. The turbine and first compressor are coupled one to the other. The waste heat boiler receives waste heat from engine jacket water and lubricating oil from a ship service generator. The evaporator cools water in a shipboard cooling loop.
