In this project we investigate the importance of biomass in a long-term sustainable energy system. Focus is on forest-based biorefineries and on the transition to a bio-based economy, and on developing a knowledge and model framework related to forest biomass and the implementation of biorefineries.
The project is structured around three interrelated PhD projects:
- Technologies and value chains (Johan Ahlström, Energy Technology, Chalmers)
- Localization and industrial change (Jonas Zetterholm, Energy Engineering, Luleå University of Technology)
- Markets and price determination (Elina Bryngemark, Economics, Luleå University of Technology)
A number of key joint issues and challenges are in focus for the three PhD projects, in particular related to how emerging biorefinery concepts can be evaluated at an early stage (ex-ante) regarding e.g. technology choice, feedstocks, process integration and geographic aspects, and how different scientific approaches, methods and models can be combined.
Aim of the project
The objectives are to: (1) contribute to the provision of skills and the development of systems analysis research in Sweden and (2) contribute with new knowledge to the sustainable transformation of the Swedish energy system.
Selection of results
- Future electricity grids with high shares of intermittent production can be combined with biomass gasification and production of biofuels (e.g. synthetic natural gas, SNG) can contribute to grid balancing.
- High conversion efficiency from biomass to biofuels is more important than economy of scale effects for integrated biofuel production based on black liquor gasification, if biorefinery processes can thus replace existing capital-intensive industrial process equipment.
- Increased bioenergy demand from the Swedish forest raw material market will lead to intensified feedstock competition, in particular regarding forest industry by-products. When an increased bioenergy demand is combined with targets for biodiversity and forest protection, the competition is further intensified which results in significant market consequences.
The project started in 2015 and will end in December 2020.
