About 4dh

4DH is an international research centre which develops 4th generation district heating technologies and systems. This development is fundamental to the implementation of the Danish objective of being fossil fuel-free by 2050 and the European 2020 goals.

With lower and more flexible distribution temperatures, 4th generation district heating (4GDH) can utilize renewable energy sources, while meeting the requirements of low-energy buildings and energy conservation measures in the existing building stock.

In 4GDH systems, synergies are created between three areas of district heating, which also sum up the work of the 4DH Centre: Grids and components; Production and system integration, and Planning and implementation.
