Carbon and fuel reduction at sea and ports -development of a new cogeneration concept with ship engine exhaust heat driven cooling generation/storage system
Although international shipping is the most carbon efficient mode of commercial transport, it was still estimated to have emitted 870 million tonnes CO2 in 2009. Part of the emission is generated by ship auxiliary engine that produces electricity for refrigeration and other electric devices on-board, while large amount of exhaust heat from ship propeller engine is wasted without further utilisation. Through applying new technologies, thermal energy management work can be done on waste heat recovery and utilisation on-board, in turn, achieve carbon abatement of shipping. Based on a Ro-Ro ship travelling regularly at northern Atlantic Ocean, a ship propeller engine heat driven refrigeration and cooling storage system is developed in terms of the transport schedule of the case ship. The thermally-activated absorption refrigeration saves about 40 kWe from auxiliary engine. The ice-slurry cooling storage system releases cooling at ports while the propeller engine heat is unavailable, therefore the overall refrigeration system generates zero carbon emission at ports, which could meet the most stringent policy in some emission controlled areas. The estimated annual emission reduction on this Ro-Ro ship is about 1176.85 tCO2 if the new system is applied.
