Swedish waste heat-to-power technology provider Climeon AB has announced that it has delivered a HeatPower 300 system to Jiangsu New Yangzi Shipbuilding Co. Ltd in China for installation onboard the first vessel in a series of dual-fuel methanol container vessels ordered as part of a newbuild program announced in September 2025.
The delivery marks Climeon’s first delivery to Jiangsu New Yangzi Shipbuilding, one of China’s largest shipbuilders.
The system was approved for delivery following the completion of the FAT, which verified system performance and functionality in accordance with approved technical documentation, class requirements, and contractual specifications. Installation onboard the vessel will take place during the construction phase at Jiangsu New Yangzi Shipbuilding.
We value the close collaboration with both the shipowner and Jiangsu New Yangzi Shipbuilding on this project. Each new HeatPower installation adds to our growing operational track record and further demonstrates the value of waste heat recovery for modern vessel designs, said Lena Sundquist, CEO, Climeon.
Waste heat-to-power
Climeon’s HeatPower 300 system converts low-temperature waste heat from engine cooling systems into electricity using Organic Rankine Cycle (ORC) technology.
With rising fuel costs and stricter emissions requirements, ORC waste heat recovery is becoming an increasingly relevant solution for improving vessel efficiency and reducing operating costs.
Climeon has several HeatPower 300 system units in operation on board container vessels, commissioned over the past year, and now producing power in commercial operation.
These installations continue to build the company’s operational track record in the marine segment.
Installation is also underway for Climeon’s system on a cement carrier under construction in China at Zhejiang Xinle Shipbuilding Co. Ltd.
