The transition to renewable energy sources presents a challenge for many district heating networks. Traditionally run on fossil fuels, the systems are built for high forward temperatures. Since many renewable energy sources have a lower temperature, new district heating networks should be dimensioned accordingly. But what about the existing grids?...
