Feasibility study- Biogas production from pelleted/briquetted straw, roadside grass and reeds

EU Commission has a target of 350 TWh biomethane by 2030 and in Sweden a target of 10 TWh was proposed. Currently, approx. 35 TWh biomethane is produced in EU and 1.5 TWh in Sweden. To enable production of biomethane, an economically viable concept is required that takes advantage of the potential from waste and residual products so that economies of scale can be achieved.

Agriculture has the largest untapped potential in Sweden, straw corresponds to 2-4 TWh/yr. The total potential from agriculture (excluding energy crops) is aprox 4-10 TWh/yr. Additional is roadside grass and reeds, which corresponds to approx. 0.3-1 TWh/yr. Alongside the political objective, there is also an increased demand for biomethane from heavy trucks, industry, and shipping, which justifies that biogas production from straw and lignin-based substrates should be demonstrated.

The project shall clarify and justify demonstration of digestion of straw, roadside grass and reeds from energy and climate perspective.
