The process can switch between two operation modes according to price signals and market demand: 1) co-production of biomethane, biochar and heat, and 2) maximised production of biomethane and heat alone. The high-purity biomethane can be distributed via the existing gas infrastructure, targeting the transport, industry and energy production sectors. The co-produced biochar can be used to displace fossil fuels in energy production and industry or in other applications, such as soil amendment. The FlexSNG approach is expected to reduce biomethane production costs by 30 % compared to state-of-the-art biomass-to-SNG technologies.

Our vision is to develop a flexible and cost-effective gasification-based process for the production of pipeline-quality biomethane, high-value biochar and renewable heat from a wide variety of low-quality biomass residues and biogenic waste feedstocks. The combination of gasification process development and feedstock supply chain optimization will lead to significant cost reductions that allow lowering biomethane production costs by more than 30% compared to state-of-the-art biomass-to-SNG technologies. The target is at medium-scale conversion plants, which allows the use of local biomass residues and biogenic wastes without heavy transport logistics.

The key innovative technology of FlexSNG is the flexible gasification process that can switch between two operation modes according to price signals and market demand: 1) co-production of biomethane, biochar and heat, and 2) maximised production of biomethane and heat. The produced biomethane can be readily injected into the existing gas infrastructure for distribution in the transport sector, heat/power production, industries and households. The co-produced biochar can be used to displace fossil fuels in energy production and industry or in material applications.

The FlexSNG concept is based on the European partners’ advanced technologies in the field of oxygen production, gasification and gas clean-up and methanation. The innovative key enabling technologies will be developed and validated to TRL5. The Canadian partners bring their expertise in feedstock supply chain management, modelling and optimization of integrated biorefinery concepts, and the Canadian perspective into the project. FlexSNG will demonstrate the targeted 30% cost reduction in concrete case studies representing both European and Canadian conditions. The proposed activities are well in line with the goals set in the work programme for international cooperation with Canada to develop new sustainable solutions for biofuels/bioenergy production.
