Europe has the ambition to utilise district heating as the backbone of the energy transition because it holds the opportunity to store energy from unstable renewable energy sources, which can then be used to cover a rising heating demand and provide a vital contribution to the European ambition of reducing carbon emissions by 40% by 2030. To realise these ambitions and utilise more renewable energy sources, Grundfos iGRID is creating low temperature zones in existing heat grids and effectively reducing heat losses and carbon emissions, based on the real-time demand. Grundfos iGRID is now being rolled out in the first European countries.
A success story: Heat loss reduction of >25% in the Greater Copenhagen area
This paper compares the source to sink efficiencies of hydrogen-based heat supply system to a district heating system operating on the same primary energy source.
