PESI - Paradigm shift in urban energy systems through synergies with industry

Analysis of different options for the use of industrial surplus energies of various shapes (waste heat, waste water, waste) and renewable energy sources in the industrial sector (e.g. solar panels on roof surfaces) in adjacent urban areas, which act as an "energy sponge". Based on real consumption and availability data, a simulation model is created and opportunities for synergies are documented.

Short Description

Status

ongoing

Summary

Starting point / motivation

Industrial companies are usually characterized by high-energy input. This goes hand in hand with the production of surplus energy, e.g. in the form of waste heat, materially bound in wastewater and waste.

Additionally, industrial firms have large unused areas which can be used for the production of renewable energy (e.g. roof areas for solar energy). As far as possible the use of excess energy already takes place inside the factories. The non-usable part, however, is normally available for external use. Here the nearby city or urban region can serve as an "energy sponge" to absorb this surplus energy.

Contents and goals

During the project, the technical characteristics of the available excess energy from industrial enterprises are raised and compared with the energy needs of cities. The synergies between city and industry are identified.

Methods

The identification of synergies is done through the collection of load curves, of demand and the availability of excess energy. In a simulation model, where also transient characteristics can be taken into account, this situation is depicted in detail. The analysis is based on real data from industrial plants and cities in the Styrian Murtal (Fohnsdorf, Zeltweg, Judenburg, Knittelfeld).

In further analysis, the basic costs for the implementation of the developed measures are determined. Here the aspects of different operating models are also taken into account. Finally, an evaluation of the environmental impact of the use of synergies between industry and city / urban area is conducted.

Expected results

As a result, implementation paths and typical synergy-potentials for an energetically and ecologically meaningful integration of excess energy from industrial plants in cities will be available. The results are incorporated in the definition of an implementation-oriented follow-up project.
