As urbanization increases worldwide, the need for sustainable energy systems for heating and cooling in cities grows. Today’s energy systems mainly use (about 80 percent in Europe) non-renewable energy sources, dependent on fossil fuels, leading to significant environmental challenges. E.ON’s ectogrid™ offers a solution by integrating a circular energy system that can reduce energy input by up to 75 percent and drastically reduce emissions.

Inspired by ectothermic animals, the energy solution adapts to the local environment and utilizes locally available energy typically from waste heat sources such as industries and data centers, but also from thermal sources such as air, water, and ground. New energy is only added to the system once all available energy has been completely shared among buildings or utilized from nearby energy sources. Since 2019, the ectogrid™ energy system at Medicon Village Science Park in Lund has resulted in a 50 percent reduction in energy input, equivalent to heating about 400 villas, and a 70 percent reduction in carbon dioxide emissions. Additionally, ectogrid™ is present in several other European projects in countries like the United Kingdom, Italy, and Germany.
