100% renewable district heating Leibnitz

DESCRIPTION

In co-operation of two different district heating (DH) operators the DH supply of the city of Leibnitz and the surrounding municipalities will be massively expanded over the next few years. The future DH system shall be supplied with 100% renewable energy from biomass and industrial waste heat. The central approach to achieve this, is to merge the two heating networks in order to enable the mutual exchange of heat to ensure an efficient, resource-saving supply. Particularly in winter, the northern operator (NO) provides heat from biomass to the southern operator (SO) on weekends when the TKV is out of operation, minimizing the gas boiler operation of the SO. In summer, the industrial excess heat, which cannot be utilized by the SO is distributed to the NO, which saves biomass feedstock. This operation strategy shall be embedded within an overall smart control system considering additional measures.

AREAS OF SPECIAL COMPETENCE

Smart municipal DH system as result of a merge of currently independent DH systems, covering distributed energy conversion facilities, industrial waste heat extraction, cascade heat supply, smart control, bidirectional heat transfer, etc.

WHAT CAN BE TESTED

The living lab will provide different possibilities to advance green energy transition in the district heating system of the City of Leibnitz while ensuring security of supply by different measures. These measures may include smart sector integration & using synergies with other infrastructures. Furthermore, user and stakeholder integration will take place.

AVAILABLE INFRASTRUCTURE

2 biomass heating plants (4 boilers, flue gas condensation), waste heat recovery (rendering plant), excess heat (biogas CHP plant), 4 thermal energy storages (3 additional storages with planned), 35 km of DH network.
