ZHENIT goal is to fully untap “on-board WH potential” developing and validating WHR solutions at different temperature levels towards the exploitation of WH for different on-board services (cooling, power, desalination) thus able to valorise heat in different vessel processes like: WH-to-Trigeneration via an innovative recuperated ORC integrated with an heat pumpt with ejector (T>100°C – NTUA); WH-to-Cooling and Desalination via an adsorption system (70
