Sweden-headed heat-to-power technology provider Climeon AB has announced that it has secured an order from Jiangsu New Yangzi Shipbuilding Co. Ltd. in China for its HeatPower 300 system, expanding the adoption of HeatPower in the world’s leading shipbuilding nation. The system will be installed on a 13,000 TEU methanol-powered dual-fuel container ship scheduled for delivery to the owner in 2027.
One of China’s leading shipbuilders, Jiangsu New Yangzi Shipbuilding, has selected Climeon’s HeatPower 300 system for the first vessel in a new series of methanol dual-fuel container ships being built for an undisclosed major Asian shipowner.
The new vessels are designed to carry 13,000 twenty-foot equivalent units (TEU) containers and are equipped with a range of energy-saving features, with HeatPower contributing directly to reduced fuel use and improved operational efficiency.
This order is the result of a long-term collaboration between Climeon, the shipyard, and the shipowner, along with a thorough evaluation of our technology. During this process, we demonstrated how HeatPower can deliver consistent and valuable efficiency gains. We greatly value the trust and cooperation of both the shipyard and the owner, and we look forward to supporting these new partners in their continued decarbonization journey, said Fredrik Thoren, EVP, Head of Marine, Climeon.
Turning waste heat into power
Climeon’s HeatPower 300 system converts low-temperature engine waste heat—primarily from jacket water cooling—into sustainable electricity using Organic Rankine Cycle (ORC) technology.
The HeatPower system’s ability to efficiently harness energy from jacket water enables more continuous power generation across different operating conditions.
This results in greater cumulative electricity generation over time, leading to increased fuel savings and lower operating costs, while also supporting compliance with key environmental regulations such as the EU Emissions Trading System (EU ETS), FuelEU Maritime Regulation, and the International Maritime Organization’s (IMO) efficiency and carbon intensity standards.
Momentum building for ORC in shipping
According to Climeon, this order from Jiangsu New Yangzi Shipbuilding highlights the growing role of ORC-based waste heat recovery as shipyards and owners are increasingly integrating cost-effective efficiency measures from the outset of newbuild projects.
It is encouraging to see both leading shipyards and shipowners recognizing the value of our HeatPower technology in improving efficiency and reducing emissions. Securing this order in China, the world’s largest shipbuilding nation, for a new shipowner that is among the largest container shipping companies, highlights the growing role of ORC-based waste heat recovery and reinforces Climeon’s position in the global shipping market, commented Lena Sundquist, CEO, Climeon.
Demonstrated performance at sea
Climeon has achieved several recent successes with its latest HeatPower generation, now producing power at sea.
These include installations on six newly built AP Moller-Maersk vessels from Hyundai Heavy Industries, with three vessels currently in operation, two retrofit projects on existing container ships, and upcoming installations on NovaAlgoma’s new cement carriers.
These references, the company says, “underline the technology’s proven performance and readiness for broader use in modern shipping.”
