Electricity without cables and batteries: HEIONIT and Düsseldorf University of Applied Sciences develop a low-energy harvesting demonstrator

HEIONIT GmbH and the Düsseldorf University of Applied Sciences have agreed on a joint research cooperation to develop a demonstrator that generates electricity exclusively from ambient heat - for the first time without a temperature gradient.

HEIONIT has designed a thermoelectric-chemical generator cell (TEC-G cell) that efficiently converts ambient heat into electrical energy. This technology enables a sustainable, continuous and self-sufficient power supply that functions independently of external energy sources. The focus is on the conversion of waste heat into electricity at low temperatures and ambient energy harvesting for the self-sufficient energy supply of small consumers.

Prof. Dr. Jens Bockstette, Professor of Energy Conversion and Storage at the HSD, is leading the research collaboration. His research focuses on battery storage, thermoelectrics and energy recovery.

“The aim of the collaboration with Düsseldorf University of Applied Sciences is to build a technically sustainable energy source demonstrator - a decisive step on the way to market maturity,” says Andreas Heine, Managing Director of HEIONIT. The next steps will be to validate the previous measurement results and develop an electrical circuit for the cyclical discharge and regeneration of the cells.

Prof. Dr. Bockstette: "From a scientific point of view, the process developed by HEIONIT has exceptional innovation potential. The intelligent use of thermochemical reactions for self-sufficient energy supply represents a real technological leap forward."
