The 37th International Conference on Efficiency, Cost, Optimization, Simulation and Environmental Impact of Energy Systems was held on the island of Rhodes, from June 30 to July 5, 2024. The conference aimed to provide a space where any interested researcher attending the congress could post a poster and/or distribute brochures or other materials on funded European projects. This allowed expert researchers to exchange knowledge and experiences in their fields of expertise. At the conference we had the opportunity to participate with a presentation about our PUSH-CCC project.
