Abstract
In the pursuit of sustainable energy transition, enhancing energy efficiency stands as a pivotal strategy to mitigate global energy consumption. A significant portion of primary energy is however lost as waste heat during various energy conversion processes, with a notable amount emitted at low temperatures. This paper examines the possibilities of waste heat recovery, with a specific focus on low-temperature waste heat recovery, emphasizing the thermodynamic constraints and technological solutions for its utilization. The study explores the emerging Carnot Battery technology as a scalable and cost-effective energy storage solution for recovering low-temperature waste heat. With Belgium as a case study, where energy consumption remains substantial across industrial sectors, this analysis quantifies and characterizes the waste heat potential, particularly focusing on low-temperature waste heat, to provide insights into its recovery and utilization. Through a comprehensive examination of waste heat recovery technologies, including Heat Pumps, Organic Rankine Cycles, and Carnot Batteries, this thesis aims to provide an overview of the potential benefits of waste heat recovery on a global industrial scale in Belgium.
