Use of biogas in traffic

Bioplin pridobivamo z anaerobno fermentacijo v bioplinarnah iz organskih snovi. Prečiščen in obogaten bioplin imenujemo biometan. Skladiščenega v jeklenkah pod tlakom 250 barov ga je mogoče uporabiti kot pogonsko gorivo v vozilih. Ker je v primerjavi z ostalimi gorivi pridobljen iz obnovljivega vira – pri kurjenju nastaja samo ogljikov dioksid in vodna para, ostalih izpušnih plinov pa je zelo malo – predstavlja zelo čisto alternativno gorivo. To je razvidno iz daljše življenjske dobe katalizatorjev ter okoljskega oziroma ogljičnega odtisa, ki je zelo nizek. Ker se v Sloveniji proizvedeni bioplin porabi izključno za pridobivanje električne in toplotne energije, je uporaba v prometu omejena samo na vozila na metan, ki uporabljajo zemeljski plin. Vendar je tudi teh, na žalost, zanemarljivo malo. Vendar pa prihodnost ni tako slaba, saj bi se investicije v ta vir energije hitro povrnile, hkrati pa bi z njegovo uporabo povečali energetsko neodvisnost Slovenije.Biogas is produced in biogas plants from organic matter by anaerobic fermentation. Purified and enriched biogas is called biomethane. Stored in cylinders under pressure of 250 bar it can be used as fuel in vehicles. As compared with other fuels it is derived from renewable resources the burning produce only carbon dioxide and water vapor, other exhaust are very few, so it is very clean alternative. The life time of catalysts is much longer and carbon footprint is very low. Biogas produced in Slovenia is used exclusively for the electricity and heat production. Because of that only cars that are methane powered can use natural gas, but also these are negligible few. However, the future is not as bad as it is seen, as the investments in this type of energy source would be quickly paid off and would also increase the energy independence of Slovenia
