Ship operators are increasingly adopting waste heat recovery to curb emissions

The shipping industry is facing increasing pressure to reduce greenhouse gas (GHG) emissions. Many shipowners and operators have adopted sustainability goals and strategies to minimize their environmental impact. One effective way to achieve this is to integrate sustainable technologies, such as Waste Heat Recovery (WHR) systems, into existing ships and new shipbuilding.

Marine waste heat recovery involves reusing the heat generated by ship engines to power onboard operations like heating, fresh water production, and electricity. However, most conventional waste heat consumers use high-temperature waste heat, while ship engines produce mainly low-temperature heat. Sustainable technologies now allow this low-temperature waste heat to be converted into sustainable electricity, reducing reliance on diesel-powered generators and resulting in fewer emissions.

One example of a WHR system is the Climeon HeatPower 300 Marine system, which uses organic rankine cycle (ORC) technology to generate CO2-free electricity from waste heat. It can operate with waste heat from a single source, simplifying integration and reducing costs. WHR systems like the HeatPower 300 Marine provide economic incentives for shipowners, with reduced fuel costs, shorter payback periods, and lower cost per kilowatt produced.

Low-temperature ORC-WHR systems are well-suited to the shipping industry’s need for long-term, environmentally friendly and economically beneficial solutions. They can be combined with other sustainable technologies and green fuels to maximize emissions reduction and fuel savings. The HeatPower 300 Marine system, for example, can be used in conjunction with clean fuels to increase a vessel’s energy efficiency without increasing fuel consumption. By integrating low-temperature ORC-WHR systems, shipowners and operators can future-proof their vessels and achieve their sustainability goals.

Overall, sustainable maritime technologies like WHR systems are playing a critical role in the industry’s journey towards a greener future. The Climeon HeatPower 300 Marine system is already making a significant impact in generating sustainable onboard electricity, highlighting the potential for fiscal and environmental benefits in the maritime industry.
