MARAD partnered with Collins Aerospace to demonstrate a waste heat recovery device on the training ship GOLDEN BEAR.  Low-grade waste heat was recovered from the ship’s service diesel generators and utilized as the heat source for a prototype adsorption chiller.  The chiller operated during the 2023 summer cruise providing cooling to the machine shop.  The cooling capacity for the chiller was measured and a simple business case developed for payback based on the installation and energy savings.
