tesa, an international manufacturer of innovative adhesive tapes and self-adhesive product solutions, is working with energy storage specialist ENERGYNEST to build one of the largest industrial power-to-heat systems with integrated heat storage in Germany at its Hamburg site.

In future, the plant will provide a significant proportion of energy-intensive process steam generation in a climate-neutral manner and will serve as a blueprint for other industrial applications.

The core of the project is a 10 MW power-to-heat plant with a thermal storage system of 40 MWh, which converts electricity from renewable energies into high-temperature steam and makes it available at flexible times. This means that around two thirds of the plant's annual steam requirements can be covered in a climate-neutral way. Annual CO₂ emissions at the site are reduced by around 4,600 tons, which corresponds to around 20 percent of site-related emissions.

ENERGYNEST's modular heat storage system consists of 24 storage modules in which heat is stored in concrete pipes. An AI-supported control system makes it possible to use cheap surplus electricity from renewable energies in a grid-friendly manner and to flexibly adapt operation to electricity prices, weather and grid load. The concept is considered economical, scalable and transferable to other energy-intensive sectors such as the chemical, paper and food industries.

"This project shows that climate-neutral industrial production is already technologically and economically feasible today," explains Dr. Ingrid Sebald, CTO of tesa SE. Alex Robertson, CEO of ENERGYNEST, also emphasizes the importance of the project as an enabler for the industrial energy transition.

The plant is a central component of tesa's "we do" sustainability strategy, with which the company aims to achieve climate-neutral production by 2030. The groundbreaking ceremony is planned for fall 2026, with commissioning scheduled for summer 2027.
