Feedstock change at biogas plants – Impact on production costs

摘要: Abstract At the beginning of millennium, regulatory changes relating to energy production from biogas triggered a significant increase in installation plants Europe. During past few years, framework has been adapted accommodate biogenic waste and agricultural residues as primary source raw materials. Based on individual data Austrian plants, this article performs detailed costs assessment case feedstock changes. Various scenarios possible material are examined assuming base scenario 500 kW plant feed with mix maize silage slurry. The presented technical economic analysis focuses “mix”, “manure”, “stover/catch crops”, “second crops”. results show that use alternative feedstocks only limited effects cost procurement advantage lower specific is counter-balanced by need for higher quantity. substantial efforts additional investments negatively impact production, resulting an average 30%.
