The Dutch project ‘Transition in Energy and Process for a Sustainable District Development’ focuses on the transition to sustainable, energy neutral districts in 2050, particularly in energy concepts and decision processes. The research results in six innovative energy concepts for 2050.

Firstly, fourteen variations of six general energy concepts have been developed and calculations conducted on the energy neutrality by means of an Excel model designed for this purpose. Three concepts are based on the idea of an energy hub (smart district heating, cooling and electricity networks, in which generation, storage, conversion and exchange of energy are all incorporated). Calculations show the energy neutrality ranges from 130 % to 164% excluding transport of persons within the district.

In this approach, different districts have different sustainable energy potentials that have their peak supply at different times. The smart approach therefore is not an autarkic district, but an exchange of surplus sustainable energy with neighbouring districts and import of the same amount of energy in case of a shortage.
