CLOSING THE LOOP: HOW INDUSTRIAL- UTILITY SYMBIOSIS IN ODENSE FORGES A BLUEPRINT FOR DECARBONIZATION
By Ronak Monga, Head of Sales Development CBS, District Energy
The global imperative to decarbonize industrial processes, particularly the heat that accounts for nearly one-fifth of global energy consumption, remains a primary challenge of the energy transition. This report examines a landmark project at the Envases packaging factory in Odense, Denmark, that offers a powerful and replicable solution with district heating.
the vast, untapped potential of surplus heat across Europe and beyond.
Through a strategic partnership with the local utility, Fjernvarme Fyn, and the implementation of advanced, commercially available technology from Grundfos, Envases has created a model for a circular energy economy. The project replaced the factory's fossil-fuel boilers with a direct connection to the city's district heating network, complemented by a sophisticated on-site heat recovery system. This dual strategy not only secures a greener energy supply but also transforms the factory from a consumer into a "prosumer" of energy, exporting its surplus process heat back into the grid. The results are definitive: an annual energy cycle of 37 GWh, comprising 23 GWh of recycled heat and 14 GWh of direct savings, and an abatement of 3,000 tonnes of CO2 per year. This article concludes that the tripartite model demonstrated in Odense, a proactive industrial partner, a capable utility, and accessible smart technology, is a highly scalable blueprint for industrial decarbonization, offering a clear pathway to unlock
The foundation for innovation: Odense's District Energy Ecosystem
Utility with a vision: Fjernvarme Fyn The success of any heat integration project depends on a capable and visionary utility partner. In Odense, Fjernvarme Fyn, one of Denmark's largest district heating companies, is a model of a forward-thinking energy provider. Its vast infrastructure, including over 2,200 km of distribution lines, creates a robust marketplace for heat. Crucially, Fjernvarme Fyn is driven by an ambitious commitment to decarbonization, with firm targets to phase out coal by 2024/2025 and support Odense's goal of carbon neutrality by 2030. This transforms the utility from a passive
