Abstrakt

A pivotal challenge for the future expansion of biogas in Denmark is the rise in use of agricultural by-products. This challenge is the baseline of the thesis ”Biogas from straw and animal manure – a feasibility study” in which the possibility of using straw in the biogas process is analyzed. In the thesis a field-to-field perspective in the value chain is applied and the possibility of adding value for the agricultural industry and for manure based biogas plants. The analyses conducted in this thesis are of interest to planners, investors and entrepreneurs, etc., who work with the development and transition of energy systems and the optimization of agricultural processes. The objective is the creation of a basis knowledge for dialogue and business development in the interaction between the biogas and the agricultural sector. Use of straw in the production of biogas is examined on the basis of a biogas case in which climate benefits, value of fertilization and construction and running cost from two concepts; the Combined Heat and Power concept (CHP) and an upgrade concept, has been assessed. In conclusion, the analyses in the thesis show that straw processed through a hammer mill is a sustainable product for biogas production and its resource base can support the political objectives of Danish biogas expansion towards 2020 and simultaneously contribute to the Danish climate targets. And so, it has been proven possible to add value for the agricultural sector in the roles of biomass suppliers and consumer and for Danish biogas plants.
