District Energy News

As part of the BAT&P initiative, four expert mini‑documentaries highlight how cutting‑edge district heating (DH) technologies and planning methodologies can drive Germany’s green heating transition. Each video features a leading technology or planning partner from Denmark—offering practical inspiration for German municipalities.

Danfoss: How Sonderborg Leads the Heat Transition

This short film reveals how Sonderborg operates over 800 km of DH pipes using innovative tools like LEAN HEAT NETWORK. It demonstrates how real-time monitoring, flexible heat sources, and intelligent load management enable a smart, low-carbon heat grid.

Logstor: Pre‑insulated Pipes – Bremen Case Study

Logstor engineers explain why pre-insulated pipes, compliant with EN 253, are essential for minimizing heat loss. Featuring Bremen’s city-wide system, the video compares pipe types and insulation classes, highlighting lifecycle cost savings and system durability.

Aalborg CSP: Pit Thermal Energy Storage (PTES)

Aalborg CSP presents its innovative Pit Thermal Energy Storage using a 70,000 m³ water pit. The video explains how PTES stores seasonal heat via low-cost electricity and renewables, ensuring flexible and cost-efficient district heating with high COP heat pumps.

PlanEnergi: How Heat Planning Enables Fossil-Free District Heating

Learn about the municipal heat planning process—one of the most critical building blocks for fossil-free heating.
Using real-world examples, this video explains how local authorities can develop structured heat plans that identify where district heating is feasible, how to phase out gas and oil heating, and how to integrate renewable and surplus heat sources.

 

Why It Matters

  • Smart Planning Tools (LEAN tools, heat mapping, forecasting) enable cost-efficient DH system operations.
  • High-Performance Infrastructure (pre-insulated pipes, PITES) boosts efficiency and resilience while reducing carbon emissions.
  • Cross-Border Collaboration brings Danish expertise to German municipalities, accelerating the heat transition with tested solutions.

What’s Next

These videos are now available on the DBDH YouTube channel and will be promoted through upcoming webinars, workshops, and local municipality outreach—driving wider uptake of district heating across Germany.
