Biogas energy opportunity of Ardahan city of Turkey

The importance of renewable energy usage is increasing gradually due to the reasons of energy supplying security, environmental pollution and reducing dependency on external sources in all over the world as also same in Turkey. Biomass is a clean and sustainable energy source that can be produced from various kind of organic waste. Turkey has considerable biomass energy potential, and about 6% of the total potential is located in the eastern region. Ardahan is one of the eastern cities of the country whose economy mainly relies on livestock farming. This paper presents biogas energy potential from animal manure and agricultural residue and corresponding CO2 emission reduction in Ardahan. Calculations were made according to the analysis of the animal manure and the agricultural crop quantities of 2015 data considering of the biochemical methane potential (BMP), availability factors, volatile solid ratio of the manure, harvested area and unit methane potential of cereals. The total electricity production potential of the evaluated biomass sources is 323 GWh/year. The total CO2 emission reduction is about 2 million tons/year in the case of biogas combustion power plant exists instead of coal fired power plants. (C) 2017 Elsevier Ltd. All rights reserved.
