Energy Cell “JOHANN”

This research project has been successfully completed. Access the Energy Cell “JOHANN” Results Fact Sheet or download the Publishable Final Report here.

While battery technology is making rapid progress, the storage of energy in the form of hydrogen is a promising area that has the potential to radically change the way we store and use energy. The innovative “JOHANN” energy cell (named after the Styrian archduke) is a technical development by the Austrian company EEG Elements Energy GmbH. It achieves an overall efficiency of 90% (electricity 30-40%). As a cost-effective conversion and hydrogen storage technology, JOHANN promises not only a high energy density, but also efficiency, durability and safety in use.

The “Johann energy cell” could be the bridge that effectively connects renewable energy sources and our daily energy needs. By harnessing the power of hydrogen, we could enter an era where clean, green energy can not only be generated, but also efficiently stored and accessed when needed. As part of the research project, the energy cell was to be developed to series maturity, demonstrated in 3 different use cases and prepared for market launch.

Utilisation of the developed sample solution

The development work still missing at the end of the project for series production is primarily the adaptation of technical components that are available for large-scale applications to the smaller scales used in the project in the consumer or private environment. The main purpose of these pending developments is to reduce costs to such an extent that they do not stand in the way of broad market acceptance. Energy Elements GmbH has stated that it will continue to develop the energy cell independently until it is ready for series production.
Elements Energy GmbH has not filed any patents for the overall system, but has applied for a patent for an electrolysis system developed in-house. An internal examination of a possible patent application is also planned for other components.
