The research group Energy Research of the RESOURCES Institute at Joanneum Research has together with the Energy Economics Group of Vienna University of Technology carried out the project “Energy storage as the key technology for renewable energy”.

In the project, based on the currently and future interesting energy storage technologies, the state of the art and possible future development potentials and areas of application were analysed and evaluated. The possibilities of mobile electrical energy storage with the option of reverse feed of power from electric vehicles into the power supply grid (“Vehicle to Grid”) were investigated, too. On the basis of 28 typical application examples in Austria, the energy storage of power, heat as well as fuel was investigated and subsequently evaluated technically, economically and ecologically.

Furthermore, the future “storable” amounts of energy in renewable energy were modelled, with the result that for an Austrian energy system with 100 % of renewable energy, solar heat and power from the “summer surplus” would have to be stored for the supply in winter.
