IN4climate.NRW publishes discussion paper

Not only private households, but above all industrial companies have a high demand for heat. On the way to climate neutrality, greater focus must be placed on the supply of process heat to the industry - especially in the industrial state of North Rhine-Westphalia (NRW). This is shown by the discussion paper of the climate protection think tank IN4climate.NRW.

In 2020, process heat accounted for a large percentage of industrial energy demand - 67 percent of the energy consumed by German industry - and is still predominantly supplied by fossil fuels (BMWi 2021a). That's almost 20 percent of Germany's total energy demand. No wonder: Whether glass, metal, cement or paper are melted, forged, fired or dried - all these processes require process heat. And in some cases up to a temperature of 3,000 °C.

In the discussion paper "Process heat for a climate-neutral industry (Prozesswärme für eine klimaneutrale Industrie)", IN4climate.NRW formulates approaches and recommendations for action for a process heat transition. A total of thirteen partners of the initiative have signed the paper.

Samir Khayat, Managing Director of NRW.Energy4-Climate: "The switch to sustainable process heat supply is one of the decisive factors in ensuring that the transformation of industry can succeed. With the IN4climate.NRW initiative, we are bringing together the expertise from science, politics as well as industry, and developing concrete strategies to put climate neutrality in industry into practice."

Various figures illustrate the need for action: Only 6 percent of the energy required for process heat has so far been covered by renewable energies. Electricity also currently accounts for only 8 percent - as an energy source, it is still far from emission-free in today's electricity mix, but must become so in the future through the switch to 100 percent renewables.

NRW alone needs 40 percent of the process heat required by the whole of Germany
Tania Begemann, Project Manager Industry and Production at NRW.Energy4Climate and author of the paper: "The sustainable conversion of process heat has always been an important and urgent topic at IN4climate.NRW, but it becomes even more explosive in times of a global energy crisis. It is estimated that NRW alone requires 40 percent of the process heat required by the whole of Germany. In order to remain economically strong and an industrial state in the long term, it is therefore of particular importance for NRW to become independent of fossil process heat sources in the near future. We would like to draw attention to this with this paper. At the same time, this enormous challenge also offers NRW the opportunity to become a pioneer."

How can this be accomplished? The discussion paper shows central approaches and recommendations for action:

• Increase efficiency: The development and use of high-temperature heat pumps should be specifically promoted within the framework of pilot plants and concepts. In addition, companies should be supported in the development and implementation of concepts that minimize process temperatures and use waste heat within the company.
• Promote renewable heat sources: Local, renewable energy sources such as deep geothermal energy and solar thermal energy can be an important component of climate-neutral process heat supply and at the same time reduce the reliance on energy imports. Where renewables can supply industrial heating needs, they should be used. These forms of energy should therefore be supported in a targeted manner through inquiries and tenders.
• Increase renewable electricity: The electrification of processes and applications is the prerequisite for the energy transition. Expanding renewable power generation along with a solid power grid, creating competitive prices for green power, and developing flexible systems are therefore key tasks.
• Promote storable alternative energy sources: To be able to generate process heat even when renewable energies are not available, industry needs large quantities of storable energy carriers. In particular, sustainable hydrogen must be available at competitive prices and the necessary conditions, such as a transport and storage infrastructure, must be created. In addition to hydrogen, biomass is a valuable and storable energy carrier and raw material at the same time. This limited resource must therefore be used in a targeted and efficient manner.

The climate-neutral generation of process heat is of great importance for the whole of Germany, but especially for the industrial state of North Rhine-Westphalia, and at the same time represents a major challenge. The heat transition in industry requires an overall systemic and supraregional view and strategy development. On the one hand, such strategies should take into account the interaction of different sectors. On the other hand, they should include all heat requirements - from buildings to industry. In this paper, decision-makers from politics, industry and society will find initial reference points and impulses for this important, common task.

The paper was developed by the IN4climate.NRW initiative under the umbrella of the NRW.Energy4Climate state organization. It is supported by the institutes Fraunhofer UMSICHT, RWTH Aachen (Chair of Technical Thermodynamics), the VDZ research institute as well as the Wuppertal Institute, the companies Amprion, Currenta, Deutsche Rohstofftechnik (German raw material technology - RHM Group), Georgsmarienhütte, Kabel Premium Pulp and Paper, Lhoist, Pilkington Germany (NSG Group) and Speira as well as the Federal Association of the German Glass Industry.

More and more sports and fashion brands are setting themselves the goal of becoming climate neutral within the next few years, on a corporate as well as product level. The CO₂ balance serves as the gateway to sustainable apparel and for more transparency for the consumer.

This process begins with the materials supplied by textile producers, requiring knowledge of the amount of CO₂ emitted during production. By evaluating and quantifying CO₂ emissions, the industry gains in transparency and can turn to more sustainable options.

In close collaboration with sustainability insights platform Higg and partners such as Climate Partner, PERFORMANCE DAYS Munich and Functional Fabric Fair by PERFORMANCE DAYS Portland seek targeted answers to the question, “How can we cut down on CO₂ emissions?” as part of its roadmap over the next three fairs. The Focus Topic “The Journey to Carbon Neutrality” will therefore highlight materials and fibers that provide solutions on how to produce and reprocess materials in the future in a climate-friendly manner, kicking off at the spring trade fair, to be held at the Oregon Convention Center in Portland on April 4-5, 2022, at the Munich’s Exhibition Center on April 27-28, 2022, continuing through the winter fair in October/November and culminating at the Spring 2023 fair.

When the conversation turns to environmental protection and climate change these days, the term CO₂ neutrality is also often mentioned in connection with CO₂ emissions and CO₂ reduction. Yet what exactly does CO₂ neutrality mean? Climate neutrality implies achieving a balance between carbon emissions themselves and the absorption of carbon in the atmosphere into carbon sinks. To achieve net zero emissions, all greenhouse gas emissions worldwide must be offset by carbon sequestration. The fashion and sportswear industries are among the world’s highest emitters of CO₂.

If one wishes to examine their emissions across all stages of the value chain, it is worth looking beyond raw materials, production, logistics and trade. Consumer behavior can also influence emissions: According to the “Fashion on Climate” report published by the Global Fashion Agenda and McKinsey at the end of August 2020, even greater leverage lies in the products themselves: 61 percent of reductions in emissions could be achieved through CO₂ reductions in material production and processing, by minimizing production and manufacturing waste, and in the manufacturing of garments. By 2030, that would account for around 1 billion tons annually. And last but not least, consumer behavior is also a factor that impacts the fashion industry’s climate footprint. If even more attention is paid to sustainable clothing, and if it is reused and worn longer, this can lead to a reduction in emissions of up to 347 million tons, according to the report.

A pioneering example on the road to sustainability was PERFORMANCE DAYS’ decision to only present sustainable materials at the PERFORMANCE FORUM from the trade fair event in November 2019 onwards. And from the upcoming Spring Fair onwards, the sustainable approach will be heightened further. Within the framework of this roadmap, the new Focus Topic is intended to accompany exhibitors on their way to climate neutrality over the course of three fairs. In doing so, PERFORMANCE DAYS and Functional Fabric Fair are pursuing a 3-step plan.  

• Step 1, April 2022: The focus of the upcoming fair will be on CO₂-reducing technologies and the measuring of a product’s carbon footprint.
• Step 2, November 2022: Within the entire Focus Topic product category, only products that indicate CO₂ emissions caused during production will be shown. This contributes to more transparency and comparability in the industry.
• Step 3, April 2023: The PERFORMANCE FORUM will present the amount of CO₂ emitted by each individual product. Furthermore, approaches to solutions will be shown as to how CO₂ released during the manufacturing of materials can be offset and further reduced.

For the best possible implementation and presentation of the new Focus Topic, PERFORMANCE DAYS and Functional Fabric Fair trust in collaborators: Higg and Climate Partner – amongst others – will accompany the next three fairs. The Higg Materials Sustainability Index (Higg MSI) is considered the leading tool for assessing the environmental impact of materials in the apparel, footwear and textile industries. The Higg MSI is able to calculate the environmental impact of millions of possible material manufacturing variants. A packaging library has also been added to assist in making sustainable decisions for packaging. The Higg Index is neither a certificate nor a label, but rather an important self-assessment tool that textile companies can utilize internally to be able to identify and improve environmental and social issues throughout their value chain.

Climate Partner, on the other hand, seeks solutions for climate protection: This involves the balancing of CO₂ emissions – which in turn are to offset the emissions of companies with recognized climate protection projects in order to make products, services and companies climate neutral. Climate Partner also sees itself as an advisor to companies on their climate protection strategies. Together, the aim is to work on reducing CO₂ emissions and to support climate protection projects that benefit the everyday lives of people in developing countries.
