Research project The purpose of the project is to investigate how low-grade biomass can be thermochemically converted with high efficiency while facilitating carbon capture with storage or utilization. In the long term, the research will promote a sustainable, circular bioeconomy with low or negative emissions of carbon dioxide and other greenhouse gases.

Biomass combustion with carbon capture and utilization or storage (BECCUS) can deliver up to 25 Mt negative CO2 emissions from industrial boilers and district heating plants in Sweden.
Oxy-fuel fluidized bed combustion (OF-FBC) is a promising route: oxy-fuel produces highly concentrated CO2 which facilitates carbon capture, while FBC enables efficient conversion of low-grade biomass.
Deployment of OF-FBC is associated with challenges related to combustion and ash chemistry, plant performance and retrofitting existing boilers. This project will generate essential knowledge to enable the implementation of BECCUS using oxy-fuel or oxygen-enriched FBC of low-grade biomass through:
