Biogas as a partial solution for energy shortages within a European gas grid infrastructure

This paper deals with biogas grid injection into the national gas grid system with the aim of upgrading the biogas to a new end-product called biomethane. This end-product which has now been cleaned has an additional benefit of an improved calorific heat value. The objective of this research document it to highlight the utilisation of this clean, locally produced energy source as a surplus energy in Central Europe. Biogas is predominantly used in the Scandinavian Countries as a transportation fuel because of the very low electricity price which makes vehicle fuel conversion more profitable. Depending on the geographical location and renewable energy driven reimbursements, biomethane can be used as a transportation fuel as well as for electricity generation, heating and refrigerating purposes. In Central Europe, biogas is mostly used for electricity production and co-generation using heat and cooling as a by-product. Biogas upgrade and injection is not very predominant in Central Europe, but still has enormous potential from a financial perspective, with fuel security and fuel production coming from renewable energy sources helping to achieve renewable energy targets.
