At the former production site of the Anker bakery in Vienna's 10th district, an innovation quarter for sustainabletechnologies is being created within the historic building fabric.

Part of its future, completely non-fossil energy supply is the former granary building with a volume of 12,000 m³ anda load-bearing capacity of 10,000 tonnes. The building is to be further developed into a large-scale storage facilityfor electrical and thermal energy that serves the grid.

The aim of this exploratory study is to investigate which technologies, dimensions and control strategies can beused to construct this large-scale storage facility and utilise it to serve the grid.

It should act as a link between renewable power generation and urban energy applications and should increase theutilisation of renewable power generation technologies and the transmission capacity of the grids.

Apart from the project management WP, the exploratory work programme is structured as follows:

1. identification of energy flows and load profiles, from both thermal and electrical energy applications and theirsupply networks

2. technology screening to identify technologies for storing thermal energy.

3. technology screening to identify technologies for storing electrical energy.

4. modelling the interaction of energy supply from renewable energy sources, storage and energy applications.

5. development of an implementation concept for the planning, construction, operation and monitoring of the grid-serving large-scale storage facility.

In addition to the mere construction and operation of the large-scale storage facility, the energy systems will alsoserve mediation purposes and will themselves be adapted to technological developments and support themexperimentally.
