On 30 June 2015, students and researchers of this institute visited ZAE Bayern in Garching. They were hosted and introduced by Mr. Läveman, associate director for energy storage. Several talks gave an overview on the topics mobile heat storage using sorption, phase change materials, ecological turnout heating and adsorption coolers. A subsequent lab tour gave interesting impressions in current experiments and developments of heat exchangers for district heating networks, borehole heat exchangers, redox-flow batteries, and dishwashers using zeolith technology.
