Thermal Storage Systems and Carbon Capture

Working group Thermal Storage Systems and Carbon Capture

Storing large quantities of renewable energy is one of the key challenges of the energy transition. Thermal energy storage systems comprise various storage technologies that store electrical energy in the form of heat and convert it back into electricity as required. The advantages of thermal energy storage include flexible storage temperatures, possible sector coupling and low specific costs of storage capacity and thus cost-effective scalability.

Another focus of the working group “Thermal Storage Systems and Carbon Capture”, headed by Maximilian Weitzer (M. Sc.), is the capture and storage of CO₂ from thermochemical processes.

The current research focus of the simulative and experimental work includes the investigation of efficient fluid mixtures for reversible heat pump-ORC processes (Carnot batteries), the analysis of new concepts for compressed air energy storage and carbonate looping processes, the storage of process-related CO₂ emissions in lime and cement production and new concepts for the active filtering of CO₂ from the atmosphere (direct air capture).
