Climeon waste heat recovery system passes a FAT milestone

Stockholm, Sweden-based waste heat recovery system specialist Climeon AB has marked another milestone. A Climeon HeatPower 300 system that will be installed on a landmark NovaAlgoma Cement Carriers (NACC) newbuilding has completed its Factory Acceptance Test (FAT). It has now been certified by classification society RINA.

At 38,000 dwt, the vessel will be the world’s largest cement carrier. It will also be the world’s first methanol dual-fuel vessel of its type and will also likely be the world’s greenest — with the Climeon system making a significant contribution to its energy savings.

The system will now be prepared for shipment to Chinese shipyard Zhejiang Xinle Shipbuilding Co. in January, with installation planned during 2026 in line with the vessel’s construction schedule.

This represents an important milestone for Climeon, as HeatPower 300 has now been approved by a new shipowner and an additional marine classification society for the first integration of Climeon’s technology on a bulk carrier.

Climeon’s HeatPower 300 system enables the vessel to generate up to 300 kW of sustainable electricity by converting low-temperature waste heat from the main engine into useful power. The solution supports Nova Algoma Cement Carriers’ ambition to improve energy efficiency while reducing fuel consumption and emissions on one of the most innovative cement carriers ever built.

RINA attended the FAT in its capacity as the classification society and on behalf of the shipowner, confirming that the HeatPower 300 meets all applicable class specifications, safety standards and documentation requirements for installation and operation on board the vessel.

The integration of the HeatPower 300 has been carried out in close cooperation between Climeon, NACC and the shipyard to ensure the system is well aligned with the vessel’s design and performance requirements.

“Reaching this FAT milestone is an important step for the project and demonstrates that our HeatPower 300 meets all requirements and expectations from a new shipowner as well as an additional marine classification society,” said Lena Sundquist, CEO, Climeon. “We appreciate the trust placed in us and look forward to contributing to improved energy efficiency on NACC’s new vessel.”

The project represents an important step in expanding the application of the HeatPower 300 to new vessel types. As the maritime sector continues to increase its focus on energy efficiency, reduced fuel consumption and carbon dioxide emissions,

Climeon’s HeatPower 300 uses an Organic Rankine Cycle (ORC) process to convert low-temperature heat into clean, carbon free electricity. As a non-weather-dependent source of green energy, says Climeon. HeatPower has the potential to diversify and safeguard the renewable energy mix and, therefore, accelerate the global transition to a net-zero future.
