Waste Heat Recovery and Digital Energy Management for Decarbonizing Shipping Vessels

transportTestedTRL 5

Imagine a ship as a giant machine that leaks a lot of heat through its exhaust and engines. Instead of letting that heat vanish, this project builds a system to catch it and turn it into electricity, fresh water, or cooling. It's like putting a recycling plant on a boat to make sure no energy goes to waste.

reduction of vessel energy consumption
The business problem

What needed solving

Shipping companies face strict EU and IMO decarbonization targets for 2030. Current vessels waste significant thermal energy that could otherwise be used for power, cooling, or water production.

The solution

What was built

Lab-scale prototypes of adsorption chillers, isobaric expansion engines, and ORC-heat pump systems, alongside a digital modeling platform for energy simulation.

Who can put this to work

Maritime Shipping
enterprise
Target: Commercial Fleet Operator

If you are a fleet operator dealing with high fuel costs and strict emission limits — this project developed a combination of heat recovery and wind propulsion that can bring up to 25% reduction of vessel energy consumption.

Shipbuilding
enterprise
Target: Naval Architect/Shipyard

If you are a shipyard dealing with the need for greener vessel designs — this project developed WHR-to-X solutions like Organic Rankine Cycle and adsorption systems that convert waste heat into power and desalination.

Maritime Technology
SME
Target: Energy Management Software Provider

If you are a software provider dealing with inefficient onboard power distribution — this project developed a digital modeling platform that simulates heat recovery integration to optimize energy use.
