Similar to aircraft applications, the reduction of fuel consumption in marine power systems is of great importance, because it leads to reduction in CO2 emissions, in travel costs and so to optimal use of fossil fuels. Moreover, the ship autonomy becomes higher. In the ECOMARINE project, in order to maximize electricity production by waste heat recovery and to simultaneously improve electric power quality, the introduction of a supplementary thermoelectric energy recovery unit is being implemented. The heat of the produced gases from a diesel generator is directly converted to electrical energy with the use of a thermoelectric generator. The typical temperature of the exhaust gases is over 300oC, thus their temperature difference from the ambient temperature corresponds to a typical thermoelectric module’s operating temperature difference. The generated voltage of the module drops with the increase of its current; hence an MPPT is required in order to achieve the maximum power output. Although ZT~ 1 materials do not provide in general the thermal efficiency and system costs to be the long term solution to industrial scale waste heat recovery, in the particular case of marine energy production, where special conditions apply, they could serve as sustainable prototype energy system components. Advanced TE materials having ZT~ 2 properties that have recently been developed and characterized and new advanced TE materials with ZT~ 4 envisioned in the long-term future will strongly enhance TEG commercialization., This work has been supported by the research program "Fuel consumption reduction in marine power systems through innovative energy recovery management (ECOMARINE)", Project Code 11SYN_7_104, within the Greek Research Activity "COOPERATION". This project is co-financed by the European Union (European Social Fund) and Greek National Funds.
