Austria is characterised by its climatic conditions and alpine natural areas. About 2/3 of the area is covered by the Alps. Harsh winter weather conditions but also approximately 48 % in total is covered by forests. Therefore, the provision with thermal energy for heating purpose has an important role in the energy landscape of Austria as well as the usage of biomass.
Around 28 % of the primary heating systems are district heating. The primary energy in district heating systems is provided by 45.4 % biomass, 35.5 % natural gas, 7.9 % residual waste. Other sources are oil (6.3 %) and coal (3.7 %). The amount of DHS has increased in the last year constantly.
There are big district heating systems in cities like Vienna and Graz as well as small – mainly renewable operated – DHS in small towns and villages. In total there are about 2,300 biomass DHS with 6,100 GWh of thermal energy. The total installed power in Austria of biomass DHS is 2.1 GW.
Current topics and challenges will be addressed in terms of energy efficiency, lowering the system temperature and integration of secondary energy sources like industrial waste heat and heat pumps. The most important goal is to increase the share of biomass and renewable energy sources in district heating systems. The aim is to ensure that the heat supply contributes to the achievement of global climate targets and that regional added value is achieved. Therefore a main focus will be addressed on the knowledge transfer between the different operators and the improvement of current facilities which will be renovated.
The tailor made Capacity Building programme for Austria covers training topics identified by Austrian DHS operators and staff during the needs assessment phase. The highest priorities have been given to technical topics as well as organisational topics and RES and EE including waste to energy aspects.
Country project partner
The Landwirtschaftskammer Steiermark (Lk-Stmk) represents the interests of Styrian farmers since 1929. Today it has around 55'000 members. Through intensive advice activity in the past 20 years, Lk-Stmk played a decisive role in Styria's development into a model region in the field of heat and electricity production based on biomass, -gas and bio-fuel transport. Within the project, Lk-Stmk is in charge of preparing feasibility studies. It will also support DHS pilot project implementation in Austria.
EU project proves decarbonisation of heating and cooling to be cost-effective with existing technologies
Is it really worthwhile to aim at low-carbon heating and cooling systems? Is it possible to achieve this with existing technologies? Those questions were answered on the basis of solid data by the soon-to end EU-funded Heat Roadmap Europe 4 (HRE4)...
First capacity-building workshop for DHS operators in Austria
The first capacity-building workshops for Austrian district heating system (DHS) operators was organised by KeepWarm's project partner Landwirtschaftskammer Steiermark on 13 November 2018 in Bad Mitterndorf. The training was attended by 35...
