The present invention refers to a new method for storing electrical energy in a solid matter. The method is based on reduction of atoms of metals in an electrical energy storage segment and on their oxidation in an energy release segment. The invention which is the object of this patent protection is a closed technological cycle with high energy efficiency that allows electrical energy storage in the form of a solid matter having a very high volume energy density. The method includes two main technological segments (i) a reduction segment and (ii) an oxidation segment that are interconnected by various support technological processes for the regeneration of solutions and gases, and heat recuperation.
F.32 International patent
COBISS.SI-ID: 4978171In cooperation with industrial partners, we developed concepts and manufactured prototype systems for demonstration of electric energy storage in solid matter. This kind of storage can be done directly by using the surplus of grid energy or indirectly by using the industrial waste heat. The heat is accumulated in the form of chemical energy in the solid matter and laer released as electric energy.

COBISS.SI-ID: 14698755The aluminium industry is one of the largest emitters of greenhouse gases (GHG) and accounts for approximately 1 % of global GHG emissions. A large portion of emissions are indirect emissions, due to the large GHG footprint of consumed electricity, while direct energy and process-related emissions are also significant. The aluminium is widely used in packaging, transportation, the building sector and for various other purposes. This study focuses on aluminium slugs, which are semi products made from aluminium alloys and are used as tubes and containers in the pharmaceutical, food and cosmetic industries. Since the aluminium industry is among the largest GHG emitters, a Life Cycle Assessment (LCA) was performed to evaluate the environmental impact of aluminium slug production. Environmental impact assessment was performed using OpenLCA software, the Ecoinvent 3.1 database and self-collected plant data. The study includes the environmental impact of anode production, electrolysis and slug production. The functional unit for the study is 1 t of aluminium slug at the company exit gate. Besides GHG emissions and the related GHG footprint associated with slug production, acidification potential and photochemical oxidation potential are further assessed. Various opportunities for GHG emission reduction are further investigated in accordance with the longer-term company strategy. If more aluminium scrap were used and carbon capture performed, the GHG footprint could be reduced by 65 % compared to the base case.
