Biovakka and Gasum engineer a revolutionary biogas production plant in Nastola
Gasum Gasum currently operates 13 natural gas vehicle filling station and aims to double the number within the next few years.According to the two companies the new facility will be Finland’s first biogas production plant, which produces gas suitable for transmitting to the natural gas network. The production of the 100 percent Finnish, renewable transport fuel is scheduled to begin in 2011. The principal designer of the 10 million euro project will be the consulting and engineering company Elomatic Ltd.
Production at the Nastola biogas production plant will be based on a process of anaerobic digestion of biomass, with raw materials to be used including sludge from municipal purification plants and other biodegradable fractions. The facility will have annual capacity to process 120,000 tonnes of biomass and generate around 50 gigawatt hours of energy from biogas. A by-process of the system will produce recycled nutrients that are ideal for use in crop farming.
The biogas produced by the plant's anaerobic digestion process will be purified and its relative methane content increased. The properties of processed biogas correspond to those of natural gas, enabling it to be transmitted into the natural gas network. The biogas produced will be utilised as transport fuel and in the future it will be available at all Gasum natural gas vehicle filling stations.
– The excellent properties of biogas can best be employed as transport fuel. It is essential that this is taken into consideration in the drafting of Finland's new legislation on production support for electricity generated using renewable sources. In its current form, the Government proposal only includes electricity generated using biogas within the scope of production support. This involves the danger that in future it will not be feasible to process biogas for use as transport fuel, says Vice President Björn Ahlnäs from Gasum Oy.
The two companies’ joint press release reveals that Finnish biogas could help cover one-fifth of the obligation set by the European Union for a 10 percent increase in the share of renewable energy sources in transport by 2020.
