Fossilfree4Industry: Phasing out of fossil gas in the manufacturing industry in the WEIZplus region




Total Project Duration

4 Years

Pilot project to demonstrate climate-friendly industry as an innovative Net-Zero-Industry-Valley
Grafik mit 5 Modelllösungen zur Substitution von fossilem Gas in Industriebetrieben.

The project

The Fossilfree4Industry pilot project aims to test, implement and scientifically support the technological issues involved in the consistent phase-out of fossil gas in industrial companies using five large-scale model solutions. In the process, multi-layered solutions are being pursued which, when viewed in combination and synergetically, are intended to ensure the achievement of the overarching goal of phasing out fossil gas for industry.

Our activities in the project

We are supporting the project with a comprehensive system evaluation of the model solutions developed with regard to ecological, economic and social KPIs. As part of life cycle analyses, the impact of the concepts on global warming potential and primary energy requirements over the life cycle are assessed. We assess the impact on production, value creation, employment, regional development and competitiveness with the help of a model-based value chain analysis.

Details of the project

The pilot project Fossilfree4Industry aims to address the current challenges facing industry in the context of the energy transition and the achievement of climate targets. Relevant technological issues relating to the consistent substitution of fossil gas in industrial companies are to be tested, implemented and scientifically monitored using five large-scale model solutions. For this purpose, multi-layered solution approaches are being pursued which, when coupled and viewed synergistically, are intended to ensure the achievement of the overarching goal of phasing out fossil gas for industry.

The project represents a good practice model with high multiplication potential for future solution elements, processes and methods in the field of industrial decarbonisation. It shows that phasing out fossil fuels in industry is possible and also makes economic sense. This will significantly boost the regional energy transition and help the region to become a model region throughout Austria. The experience gained in the Weiz+ region - which includes 41 municipalities, 120,000 inhabitants and around 5,000 businesses - (click for further information) can subsequently be transferred to a large number of other regions and countries.


Project aims:

The overall goal is to answer the relevant technological questions (at component and system level) regarding the consistent substitution of fossil gas in industrial and commercial operations. Consequently, we intend to transfer these to selected locations (prototype model solutions) in the region, realise them and provide scientific support to ensure that they are rolled out in the region and beyond. The aim is to consistently utilise the region's own potential (waste heat, residual materials and local renewables) on the one hand and to establish higher-level renewable conversion plants and distribution structures on the other.

Five approaches were defined in order to achieve this goal, which, when considered together and synergistically, should ensure the achievement of the overarching target.



  • Energy supply for industry at 2 temperature levels
  • Using waste heat from industry
  • Increasing the output of green gas production
  • Using regionally available energy sources for district heating
  • Strengthening the energy supply infrastructure
