Adsorption heat storage for the commercial heat transition

Focus topic:	Resource efficiency
Type of funding:	Project funding programmes
Programme:	CZS Transfer
Funded institution:	Ernst-Abbe-Hochschule Jena

The aim of the project is to develop an adsorption heat storage system that can store regenerative heat and provide temperatures above 100 °C, as required in the commercial and service sectors, for example.

Goals

Ensuring a CO2-neutral heat supply for new and existing neighborhoods that is independent of oil and gas imports is one of the future challenges on the path to climate neutrality and raw material independence for Germany. The commercial and service sectors in particular require the provision of heat at temperatures above 100 degrees °C (e.g. breweries, paint shops, laundries). With renewable heat, this can hardly be realized with the technologies available on the market.

While electricity generation and storage technologies are currently in the focus of research, research efforts in the field of heat storage are still underrepresented despite strongly increasing natural gas prices.

Therefore, the goal of the project is to develop and laboratory test a zeolite-based adsorption heat storage system capable of storing solar/regenerative heat and providing it at commercially relevant temperatures above 100 °C for mixed-use developments in cities.
