Bioenergy (forestry residues, used wood, waste) is the largest energy source in Sweden, mainly in the forest industry and for district heating including combined heat and power. Vattenfall operates several district heating systems delivering not only heat, but also cooling and electricity, to several hundred thousand customers.
Vattenfall’s R&D work is focused on technology development of biomass utilisation for district heating and on optimised production and distribution of heating, cooling and power. Most of the work aim at implementation within 1-5 years, but an element is also possibilities for district heating in the long-term energy system (post 2030).
Improved production of power, heat and cooling
- Increased availability of the production units
- Process data follow-up for optimised production
- Proactive emission handling
- Corrosion control and high-temperature materials
Optimised district heating and cooling distribution
- Improved condition-based maintenance of the distribution grids
- Prioritisations of investments in the district heating distribution systems
- Relining as a solution to reduce the reinvestment need in distribution systems – or not?
Sustainable fuels now and for the future
- CO2 neutrality 2030
- Renewable fuels quality control
- Accepted routes for waste fuels in district heating
- Sustainable handling of by-products
Technical solutions and future possibilities for district heating
- R&D scan the state-of-art for the above areas
- District heating in combination with analyses of possible future energy systems
- Selection of areas for further investigations of new possibilities
