Copenhagen – Maritime giant Maersk undertakes what could be one of the first modernizations and tests of an electrical heat recovery system aboard one of its container ships in collaboration with a Swedish technology company Climeon which develops heat recovery systems for marine and other applications. The demonstration project is one of the techniques the container shipping company is exploring as it seeks to play a leadership role in the development of new technologies to improve the efficiency and environmental performance of commercial transportation. . Climeon announces the successful integration of the thermal energy system commissioned aboard a Maersk container ship. Maersk will begin to assess the potential of waste heat recovery technology to increase energy efficiency: “After numerous delays due to the Covid-19 restrictions, we are delighted to start power generation and assess the potential aboard the Maersk container ships, ”said Fredrik Thoren, head of the maritime division at Climéon. – We are very grateful for the professional support and genuine enthusiasm shown by the Maersk team to ensure the success of this collaboration.
The Climeon Heat Power System recovers residual heat, in the form of jacket cooling water and excess steam from the vessel’s main engine. The recovered heat is used to generate electricity for the ship’s grid, thereby reducing the electrical production required from the ship’s generators. The technology automatically and continuously ensures that the output power is optimized for maximum conversion efficiency via the Climeon Live control system. The software provides daily system information and reports, facilitating proactive system monitoring, ensuring maximum uptime The current installed system has the capacity to produce 150 kW, but the system is scalable up to 1 MW. Climeon says that in addition to improving the vessel’s existing Ships Energy Efficiency Index (EEXI), their system can reduce annual CO2 emissions by up to 3,500 tonnes, which equates to annual fuel savings. of 1,000 tons.
Climeon’s first maritime application took place in 2015 on board the two-year-old “Viking Grace” ferry, powered by LNG. which sails between Sweden and Finland. The system was installed on the ferry and according to the company, after a successful test period the CO2 and fuel savings were higher than expected, which led Viking Line to develop cooperation with Climeon. Other applications of heat recovery technology include installation on Virgin Voyages’ new cruise ships built by Fincantieri. The technology is also on board the new Norwegian Havilah cruise ferries, the first of which entered service this week and sails the Norwegian coast. The company hopes that the demonstration project with Maersk will help expand the use of heat recovery to wider segments of the marine industry.
