The Interreg Aurora funded BEAR project aims to increase biogas‑based energy production in Arctic regions by improving the efficiency of biogas plants through three integrated research areas: predictive process optimization, innovative raw‑material substrates, and enhanced microbiology. To achieve this, the project brings together the complementary strengths of its partners – the University of Oulu contributes a predictive optimization model for smart process control, SLU advances microbiological understanding to improve reactor performance, LTU develops substrate innovations to enhance fermentation, and Luke provides energy‑efficiency modelling supported by detailed chemical analyses, while Digikierto Oy evaluates the economic impacts and develops practical deployment pathways.
Building on the BITUPROP dynamic model, the project will refine and test a smart control system that continuously uses real‑time process data to forecast plant performance up to two weeks ahead. When coupled with substrate innovations and improved microbial populations, the system supports more precise feeding strategies, enhances fermentation efficiency, and improves the overall energy balance.
Biogas production in Northern Scandinavia faces notable challenges due to the cold climate, which increases the investment threshold and limits the establishment of new plants, leaving significant green‑energy potential untapped. By testing and validating this combined optimization approach across several biogas plants over a 12‑month period, the project seeks to boost energy output, enhance energy self‑sufficiency, reduce methane emissions, and strengthen plant profitability.
Cross‑border cooperation between Finland and Sweden provides a broader knowledge base and ensures that the model can perform under diverse operating conditions. The primary target group is SMEs that operate or plan to establish biogas plants, supported by five commercial test plants and several biogas‑related partners. The project supports EU strategies such as the Green Deal and REPowerEU by advancing sustainable, decentralized, and efficient energy production in the Arctic region.
