Abstract:
1. A system for capturing and storing energy from heat expelled in engine exhaust, the system comprising: a generator configured to receive the engine exhaust and circulate a first solution comprising a solute, the solute vaporizable into a gaseous state by heat absorbed from the received engine exhaust; a condenser fluidly coupled to the generator for receiving solute vaporized from the first solution, the condenser configured to condense the vaporized solute into a liquid state; an evaporator fluidly coupled to the condenser, the evaporator comprising a first fluid passage for circulating the condensed solute and a second fluid passage for circulating a second solution, the first and second fluid passages arranged to provide heat exchange therebetween so that the condensed solute circulating within the first fluid passage is vaporizable into the gaseous state by heat absorbed from the second solution circulating within the second fluid passage to thereby cool the second solution; and a thermal storage tank configured to house a third solution for storing thermal energy, the thermal storage tank thermally coupled to the evaporator for exchange of thermal energy between the second solution and the third solution.
