Sweden-headed heat-to-power technology provider Climeon AB has announced the successful commissioning and handover of its HeatPower 300 system onboard a container vessel operated by a global shipping and logistics leader committed to decarbonizing ocean transportation. This marks a major milestone in the previously announced retrofit project, confirming the system is now fully operational and generating electricity from onboard waste heat.
Following the installation of the HeatPower 300 system in early 2025, Climeon’s team carried out commissioning activities to ensure the system was properly integrated with the vessel’s existing systems, running reliably and delivering power to the vessel, and meeting all applicable safety requirements.
With these steps completed, the system has now been handed over for operational use as part of the vessel’s onboard energy efficiency measures.
This is a meaningful milestone and a strong example of how waste heat recovery can support efficiency improvements on existing vessels. The efficient installation and commissioning of the system highlights the practicality of this solution for shipowners aiming to reduce emissions and fuel consumption as regulatory demands continue to increase, said Fredrik Thoren, EVP and Head of Marine Sales at Climeon.
Utilize low-grade residual heat
Climeon’s Organic Rankine Cycle (ORC) technology, HeatPower 300, is designed to generate electricity from low-temperature waste heat from the vessels’ engines, including jacket water, HT cooling water, and, when available, steam.
Climeon’s HeatPower technology is one of the few solutions capable of recovering useful energy from these lower-grade heat sources, enabling shipowners to reduce fuel consumption while supporting compliance goals.
The HeatPower 300’s modular platform is designed for straightforward integration into a variety of vessel types and operational profiles.
Its flexibility supports both retrofit and newbuild applications, allowing shipowners and shipyards to incorporate waste heat recovery without disruption to vessel design or operations.
The successful commissioning of this system strengthens Climeon’s track record in marine waste heat recovery and demonstrates how ORC technology can be deployed to support long-term environmental and operational goals.
