Stena Line seeking novel approaches to recover energy from exhaust gases from ship engines

Green Car Congress

Stena Line is seeking novel, cost-effective approaches to recover energy from exhaust gases from ship engines and to transform it into a more useful energy form (e.g., electricity to supply hotel loads on board the ship). These energy losses are primarily radiant heat loss and the sensible heat of exhaust gases.
