14 - 17 September 2026
Linz/Austria
The geopolitical situation, high fossil fuel prices, and energy security risks show the urgent need to increase domestic and renewable energy sources. As a CO2-neutral fuel, sustainable bioenergy is a key component in decarbonising and securing our energy supply. Market transformation towards modern, efficient and low-emission bioheat systems offers significant opportunities for affordable and local energy supply as well as climate and environment protection.
The International Training Seminar focuses on small- to mid-scale projects fuelled by wood pellets and wood chips. It covers solutions for homes, smaller commercial/public buildings and district heating grids (up to a few Megawatt).
The seminar offers interactive learning in an international group, educational site visits and presentations by experts in bioenergy technologies, market development and the sustainability of bioenergy.
As an international training seminar, the programme does not cover country specific information, such as specific legal aspects or funding programmes.
Representatives of businesses, public bodies, institutions, NGOs etc. interested in developing bioheat markets. It is especially targeted to persons from countries where the market for automatic bioenergy heating is in an early phase.

Upper Austria is one of Austria’s nine federal states/regions and has a population of 1.5 million. It holds a leading position in bioheat: 17 % of primary energy comes from sustainable bioenergy, 32 % of dwellings are heated with clean bioenergy and there are over 6,000 jobs in the bioheat industry. Upper Austria has one of the highest densities of small-scale automatic bioenergy heating systems in the world.
The region has given political priority to energy efficiency and renewable energy since the mid-90s. Renewables currently cover 37 % of the region’s primary energy demand: 17 % bioenergy, 12 % hydropower, and 8 % solar and other renewable energy sources. 71 % of all space heating already comes from renewable and waste heat. Strategic decision-making and comprehensive actions in sustainable energy policies have resulted in high-performing markets for clean heating. Bioenergy is an important economic driver for the region and plays a key role in the region’s ambitions for achieving climate neutrality. Over 1 billion Euro per year are invested in bioenergy fuels and equipment.
The International Training Seminar is organised by the Energy Academy of the OÖ Energiesparverband, the regional energy agency of Upper Austria. OÖ Energiesparverband drives the energy transition by promoting energy efficiency, renewable energy, e-mobility and innovative energy technologies. It provides comprehensive services to citizens, municipalities and businesses of all sizes. It carries out over 10,000 face-to-face energy advice sessions each year. It also supports energy technology companies in the Cleantech-Cluster.
In the context of its Energy Academy, OÖ Energiesparverband holds over 30 training courses with more than 1,000 participants each year. It is also the organiser of the European Pellet Conference, the world's largest annual event on wood pellets.
The Cleantech-Cluster (CTC) is the platform for energy and environmental technology companies in Upper Austria. It supports innovation, competitiveness and visibility of its more than 250 partner companies. In the energy technology sector, partner companies employ over 30,000 people and achieve a combined annual turnover of more than 5 billion Euro. More than 25 % of all modern small-scale bioenergy boilers installed in the EU are manufactured by Upper Austrian companies and pellet heating systems have become a standard solution in the region.
According to the IEA, forest bioenergy is an important part of sustainable energy provision in Europe, particularly for heat production. It is therefore a key piece of the energy transition and energy security. Over 90 % of biomass used for energy comes from European resources. Sustainably managed forests continue to absorb carbon from the atmosphere. In addition to timber or pulpwood, they provide important amounts of low quality wood resources and residues that can be used for energy. No forests have to be cut down for it.
The development of the bioheat market in Austria stands on three quality pillars:
Bioenergy comes from CO2-neutral and sustainable fuels (mostly pellets and wood chips) produced from residues from sustainable forestry and byproducts from the wood industry. The quality and convenience of modern, fully automated, ultra-low emission heating equipment generate consumer trust. Strict criteria ensure that only highly efficient technologies are installed.
Linz is the third-largest city of Austria and the capital of the region of Upper Austria (Oberösterreich). It is located in the north of Austria, on both sides of the Danube river. The city has a population of 215,000. Named the "Cultural Capital of Europe" in 2009, Linz combines an industrial heritage with modern cultural highlights (e.g. Ars Electronica Center, Lentos Art Museum, modern opera house etc.).
