Push2Heat: Felix Schoeller installs the Group’s first high-temperature heat pump at its Weissenborn plant

In the framework of the EU-funded Push2Heat project, four demonstration plants are being planned in Europe in a collaboration of international partners and research institutes. At its Weissenborn site, Felix Schoeller is working with Fraunhofer IEG and heat pump supplier SPH to design and build a high-temperature heat pump that uses waste heat from paper production to generate new process steam for the drying stage. An existing 45°C waste heat circuit is used as the heat source. The heat pump generates steam at 124°C with a COP (coefficient of performance) of approximately 2.5, which can be directly reused in production.

Ziele des Projektes

The project aims to demonstrate the contribution that high-temperature heat pumps can make to the decarbonisation strategy of the Group. In addition to the CO2 savings achieved, economic efficiency and process safety are of great importance to us. The exchange of ideas in the international project and the support of our partners provides a comprehensive basis for achieving these goals.

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.

CO2 emissionens saved

CO2 emissions saved through reduced natural gas consumption: approx. 1,200 tonnes of CO2 per annum

Amount invested

This project was funded by the European Union’s Horizon Europe research and innovation programme under grant agreement No. 101069689 (PUSH2HEAT).

Amount of investment in Horizon Call No. 101069689 (Push2Heat) for 4 demos and all participating institutes approx. €10 million.
