L2M – Innovative Strategy for Reducing Energy Consumption and Pollutant Emissions in Liquid Fuel Carrier Ships

This project will develop two integrated boil-off gas recovery and re-liquefaction systems for liquefied natural gas and liquefied hydrogen carriers that harness ship exhaust heat and convert it into usable energy through the Kalina power cycle and water-ammonia absorption refrigeration unit. Unlike conventional re-liquefaction systems that require burning additional fuel to produce cooling, the proposed solution will utilize waste heat to reduce onboard energy demand. This approach lowers operating costs by decreasing fuel consumption for BOG management, reduces greenhouse gas and other pollutant emissions, improves coastal air and water quality, and helps operators meet the International Maritime Organization standards through a scalable and optimized design. For the partner organization, this project will create practical, low-carbon technologies that can be adopted by shipbuilders, shipping companies, and clean-tech providers. It will reduce operating costs, improve environmental performance, and support Canada’s role as a reliable and sustainable energy exporter.
