Supporting energy efficiency on the world’s largest methanol-powered cement carrier with ORC heat recovery technology
As the maritime industry accelerates its transition to low-emission operations, shipowners like NovaAlgoma Cement Carriers (NACC) are showing what’s possible when bold sustainability commitments are paired with proven energy solutions. By combining renewable methanol propulsion with advanced energy efficiency technologies, NACC is setting a new benchmark in sustainable bulk shipping.
Now, with the next vessel in its advanced cement carrier series moving into development, NACC has once again chosen Climeon’s ORC-based HeatPower 300 waste heat recovery system. Building on the collaboration around the first methanol-enabled ship already under construction, this follow-up project reflects a continued commitment to reducing maritime emissions through innovation and partnership.
A Repeat Order Reflects Continued Trust and Momentum
Climeon has received a second order from NACC to deliver its HeatPower 300 waste heat recovery system for another cutting-edge cement carrier. The vessel will be built at Zhejiang Xinle Shipbuilding in China and, once delivered in 2027, will become the world’s largest cement carrier powered exclusively by renewable green methanol.
By operating on clean fuel and integrating multiple energy efficiency technologies—including Climeon’s waste heat recovery system—the vessel is expected to reduce CO₂ emissions by more than 60% compared to conventional designs. This translates to approximately 180,000 tons of CO₂ avoided over a decade of operation.
Extending a Successful Collaboration
This second vessel follows positive progress on the first project between Climeon, NACC, and the shipyard—where alignment between owner, yard, and technology supplier has enabled smooth integration of sustainability features from the early design stage.
Making Methanol More Viable Through Waste Heat Recovery
Methanol continues to gain traction as a clean alternative in marine propulsion, but its higher cost compared to conventional fuels presents a financial hurdle for operators. This makes it increasingly important to recover as much onboard energy as possible to reduce overall fuel demand and emissions.
Climeon’s HeatPower 300 system helps address this by turning low-temperature waste heat—especially from the engine’s jacket cooling system—into clean electricity through ORC technology. Because jacket cooling water is always available during engine operation, the system is able to generate power more consistently over time—even as conditions onboard fluctuate. This enhanced performance leads to higher total electricity production across the vessel’s lifetime, easing the economic burden of using more expensive fuels like methanol while supporting compliance with decarbonization regulations.
Strengthening Compliance and Decarbonization Strategy
With regulations tightening—through frameworks such as the IMO’s CII (Carbon Intensity Indicator) and EEXI (Energy Efficiency Existing Ship Index)—waste heat recovery is increasingly becoming a compliance enabler.
By improving overall energy utilization, Climeon’s technology supports shipowners in meeting environmental targets without sacrificing economic performance. It also adds value for shipyards and designers seeking to offer future-proof, regulation-ready vessels.
Partnering for Greener Cement Shipping
The cement industry is among the most energy-intensive in the world. By investing in low-emission, fuel-efficient transport, companies like NovaAlgoma are showing leadership in maritime sustainability. Climeon is proud to contribute to this journey—demonstrating how ORC-based waste heat recovery can support green shipping across even the most demanding industrial sectors.
As demand grows for low-emission, high-efficiency newbuilds, Climeon’s repeat order signals more than project success—it reflects a broader industry shift toward smarter, cleaner energy use at sea.
