Hi CBest – IEA ES Task 44 PtH and Heat-integrated Carnot Batteries for Zero-Carbon Heat & Power supply

The decarbonisation of industry poses a particular challenge for the future. Aligning volatile renewable generation with mostly continuous industrial processes requires suitable storage solutions coupled with efficient conversion technologies. At the same time, the industrial sector partly demands high temperature levels, which have been largely provided by the combustion of fossil fuels so far. The task aims to strengthen the role of power-to-heat (PtH-) applications and power-to-heat-to-power (PtHtP-) systems (Carnot batteries) in the decarbonization of industrial processes and connected heat and power grids and to identify and evaluate suitable system concepts and use cases for the different technology configurations.
This builds on findings from the predecessor task IEA ES Task 36 on Carnot batteries. After completion of the project, high-quality techno-economic information on PtH- and PtHtP-systems in the application context will be available, laying the foundation for a broad market introduction. Analyses and evaluations of various system concepts, basic technologies and regulatory framework conditions provide potential implementers with scientifically sound implementation options. AEE INTEC contributes its expertise in thermal energy storage, heat pumps, and the decarbonization of industrial processes, and leads Subtask C. This Subtask is about identifying suitable use cases.
