Oxy-fuel combustion of solid biomass for negative carbon dioxide emissions

Research project Florian Schmidt at the Department of Applied Physics and Electronics at Umeå University, together with researchers at RISE, receives SEK 7.7 million from the Swedish Energy Agency to investigate how biomass converts thermochemically in a carbon dioxide-rich atmosphere.

In Sweden, combustion of solid biomass together with carbon capture and storage (BECCS) has the potential to generate >10 million tonnes of negative carbon dioxide emissions per year until 2045. The most promising way to achieve this is to implement oxy-fuel biomass combustion and CCS in existing plants for heat and power generation and waste incineration.

Project description

Oxy-fuel combustion produces a flue gas that consists of highly concentrated carbon dioxide, which can be directly compressed at low cost for permanent storage. However, systematic experimental studies of solid biomass oxy-fuel combustion, and studies on larger scale are scarce. The objective of this project is to acquire essential knowledge necessary to implement the technology in the Swedish energy system. Pilot-scale experiments will be conducted using advanced diagnostics and different types of biomass to address key issues, such as process stability and control, and gas- and solid-phase combustion chemistry in a carbon dioxide-rich atmosphere.
