According to the abstract released by the Intellectual Property India: "The project focuses on the development of an ammonia-based waste heat recovery system for electricity generation in two-stroke engines of oil tankers. Large amounts of heat generated in engine exhaust and cooling systems are typically wasted, reducing overall efficiency. This system captures the low-grade waste heat and converts it into electrical energy using an ammonia-based Rankine cycle. Ammonia is chosen as the working fluid due to its high latent heat and low boiling point, which make it suitable for efficient heat-to-power conversion. The recovered energy can be used to power onboard electrical systems, reducing dependence on auxiliary engines. Performance analysis indicates a significant improvement in energy utilization and overall engine efficiency. Additionally, the system contributes to lower fuel consumption and reduced greenhouse gas emissions, promoting environmentally friendly operation. Practical implementation considerations, such as space constraints, safety, and maintenance, have been addressed. The design is feasible for oil tankers and can be adapted for other marine engines. Overall, this project demonstrates an effective method for improving energy efficiency and sustainability in marine transport."
