Abstract
This memo explores the potential and feasibility of different heat‐to‐power technologies for application
in industrial surplus heat recovery. Several technologies are described and evaluated qualitatively for
typical low‐to‐medium temperature heat sources in HighEFF partner industries. The evaluations are
based on published literature as well as research experience at SINTEF Energy Research. RC‐based
technologies and absorption cycles were found to have most potential, whereas conventional and novel
technologies such as the Stirling engine and PCM technology were found to be less promising. Literature
indicates that total system size and heat source temperature are critical to thermodynamic performance,
and should be considered in fair comparison between technologies. This memo serves as basis for future
activities in WP3.1 Energy‐to‐power conversion, including a quantitative evaluation of promising
technologies.
