New Finnish CBG statistics: Biogas combines highest environmental quality with lowest price
Statistics of production and consumption of biogas for transportation applications in Finland during 2014 was published in September 2015 by the University of Eastern Finland (Lampinen 2015) as a part of national biogas statistics publication (Huttunen & Kuittinen 2015). Here is a short overview of the traffic biogas section of the publication (which was written in Finnish).
Environmental quality of biogas consumed as vehicle fuel in 2014 was very high, as it has been before. The graph on the left shows energetic distribution of resources used for producing CBG (Compressed BioGas) for filling stations. All was waste based consisting of biowastes (99.99 %) and lignocellulosic plant wastes (0.01 %). Energy crops were not used. It means that all CBG is eligible for double counting in the national renewable energy statistics according to the rules of the RES Directive. Since energy use does not affect nutrient recycling in biogas processes, nutrients could be recycled independently.
As biogas was sold for vehicles only in pure form, as CBG100 (100 % Compressed BioGas), it had by far the lowest average lifecycle greenhouse gas intensity of all energy sources available in public filling/charging stations for vehicle use in Finland.
And biogas was also available at lower price than any other energy form in public filling/charging stations.
Combination of highest environmental quality and lowest price was complemented by highest technical quality (octane number 130-150) of fuels suitable for Otto engines. Suitability for Otto engine, i.e. the most common and the cheapest vehicle engine, also means that cars able to utilize it are in the same cost range with conventional gasoline and diesel cars in the Finnish market. As a result of extension of the public CBG100 filling station network, personal renewable energy transition in transportation energy consumption became possible in practice and without financial burdens for about a third of the Finnish population.
