Electro-thermal energy converter using novel combined thermoacoustic and electrocaloric system

2026-07-22

Energy and transport are the highest emitters of greenhouse gases in the EU at 25% and 21% respectively of total emissions. Efficient management, conversion and distribution of thermal energy as well as converting excess or wasted heat into electricity presents a major opportunity to reduce greenhouse gas emissions and achieve net zero by 2050 in the energy and transport sectors and beyond e.g. heating and cooling distribution in buildings and districts, improved efficiency in renewables and more efficient, longer range electric vehicles. THERMINATOR will develop a new energy conversion technology in the form of an efficient low profile energy conversion “skin” that can be integrated into the fabric of a building or the wall of a pipe to reduce energy loss through active insulation or to provide temperature conversion in heat networks. It could be applied as a backing to improve efficiency of solar cells or integrated into the structure of a vehicle to support passenger comfort or improved efficiency of structural batteries. This novel technology integrates thermoacoustic and electrocaloric stages and operates at high frequency to achieve high power density (100W/cm2). Model-based smart controls and energy management will provide high efficiency and digital control for optimum performance and reliability and integration into digital networks. A focus on sustainability, circularity and socio-economic factors will ensure products with high environmental and social benefit. Developments will be validated to TRL4 by testing in use cases in thermal networks, solar generation and electric vehicle applications. THERMINATOR disruptive technology will support European companies in developing new high performance sustainable products through consortium members in thermal networks and solar power sectors alongside world-leading expertise in electrocaloric, thermoacoustic and ultrasonic technologies and skills in reliability, environmental assessment and exploitation planning.
