Helen Carlström, The Fifth Generation of District Heating - ECTOGRID, EON

Helen Carlstrom, representing E.ON, took the stage to introduce the groundbreaking concept of the Fifth Generation of District Heating, known as Ectogrid. With urbanization and sustainability driving the transformation of the energy landscape, Carlstrom highlighted the crucial role of district heating in reducing CO2 emissions from heating and cooling.
Addressing the challenges faced by cities, Carlstrom emphasized the need to decarbonize existing urban areas with high energy demands and variable energy markets. She also acknowledged the increasing electrification demands that surpass the pace of grid expansion, underscoring the importance of joint optimization of heat, cooling, and power for achieving energy autonomy.
Carlstrom presented the evolution of district heating, spanning over a century, with each generation adapting to changing needs. From the first generation in 1880, operating at temperatures above 200°C, to the fourth generation in 2010, characterized by temperatures below 60°C. The fifth generation, envisioned for the future, revolves around low and flexible system temperatures.
Introducing the E.ON Ectogrid, Carlstrom showcased a revolutionary approach to district heating. This integrated energy system caters to both heating and cooling requirements, leveraging innovative cloud technology for automation and cost reduction. The Ectogrid utilizes standard components, ensuring flexibility and scalability. Moreover, its low-temperature network facilitates energy sharing between buildings, maximizing the reuse of low-level waste energy and significantly reducing the climate footprint.
The audience at the conference was captivated by the Ectogrid's potential to reshape the district heating landscape and propel the transition towards sustainable and efficient urban energy systems. The simplicity of its design, coupled with its ability to integrate renewable energy sources and optimize energy consumption, garnered significant interest among attendees.
Carlstrom's presentation ignited discussions on the practical implementation of the Fifth Generation of District Heating and the role that Ectogrid can play in accelerating the decarbonization of cities. Participants expressed enthusiasm about the prospect of utilizing standardized, scalable solutions and embracing innovative technologies to achieve climate goals.
