“…4). On the basis of this analysis three phases of diffusion of agricultural AD plants in the Czech Republic were identified, corresponding to the classical model of spatial diffusion (Hägerstrand [67]; Haggett [68] [73]). It can be said that the crucial driving force behind the diffusion of this technology is the supportive financial incentives in individual countries, which vary in both type and intensity of incentive.…”

There is fundamental agreement about the environmental benefits of renewable energy technologies, but unintended consequences arising from their deployment are frequent sources of conflicts. The Czech Republic has committed itself to supply 13.5% of its electricity consumption from renewable sources by 2020. High state incentives for renewable energies have been provided to achieve this target, however critical questions can be asked about the appropriateness of the design of the supporting frameworks which caused a boom in photo-voltaic (PV) installations on agricultural land, as well as a boom in the installation of agricultural anaerobic digestion (AD) plants fueled by dedicated energy crops. This paper analyses the diffusion of agricultural AD plants in the Czech Republic, focusing especially on locational characteristics in relation to the quality of agricultural land, agricultural and population census data. Statistical analysis of those spatial datasets show that agricultural AD plants are mostly located in less favourable agricultural areas, in regions having recently experienced a reduction in cattle breeding, and in regions with significant increases of sowing areas of green maize. These findings suggests shortcomings in the supporting policy for AD plants in the Czech Republic, resulting in unintended environmental consequences, and missed opportunities to enhance energy self-sufficiency and resilience in the countryside.

Experimental work was carried out for the production of Biogas from poultry waste water. The Poultry waste was collected from farm near Nagercoil at Kanyakumari District. Batch anaerobic digester was designed for 20L capacity. The experiment was carried out for 36 days to monitor the performance. Various parameters like pH, TS, COD have checked for every 24hours. The Production of biogas was measured by water displacement method. The methane content was analyzed by gas chromatography test. Based on the experimental data, kinetics studies have done for various models like Line Weaver-Burk method, Eadie-Hofstee method, Hanes-Woolf method. The Eadie-Hofstee Method has provided better prediction than other method. These results thus indicate that, Eadie-Hofstee Method is best to identify the growth rate, substrate concentration and Limiting Substrate Concentration of the system. The sludge of the poultry wastewater and digester were characterized by SEM analysis. The imaging was done to determine the morphological structure of the sludge and to view the bacterial growth on the surface of the sludge.

“…Biogas flowrate per kg VS and biogas compositions (Table 2) were quantified by using the Boyle-Buswell stoichiometric relationship [39] considering that the total volatile solid content of the slurry can be degraded by the microorganisms in the anaerobic digester. This is a common methodology that has previously been applied in several articles [12][13][14][15] aiming to assess the potential for biogas and energy generation from organic solid waste via the anaerobic digestion process. It was assumed that the introduction of bio-diesel scrubbers downstream of the AD reactors would enable the reduction of NH 3 and H 2 S content to acceptable levels for being used as fuel in gas engines [40].…”

“…Efficiency for ORC pumps and expanders was determined using linear correlations taking into account thermal inputs for the cycle, based on data for currently available machinery on the market [53]. Capital costs for ORC systems were estimated using the correlation presented in Equation (5) and operation and maintenance costs were quantified by considering the yearly specific values for O&M costs to be £ 55.6 per installed kWe [15]. Values were updated to current value of UK sterling using CEPCI and the corresponding exchange rate.…”

“…The technical and economic feasibility of AD plants in the context of agriculture and farm waste processing has been analyzed by a number of researchers [12][13][14][15]. These studies focused on the investigation of the techno-economic performance of the AD reaction system, rather than extensively analyzing energy conversion technologies for biogas.…”

Potential for Energy Production from Farm Wastes Using Anaerobic Digestion in the UK: An Economic Comparison of Different Size Plants

et al. 2017

Anaerobic digestion (AD) plants enable renewable fuel, heat, and electricity production, with their efficiency and capital cost strongly dependent on their installed capacity. In this work, the technical and economic feasibility of different scale AD combined heat and power (CHP) plants was analyzed. Process configurations involving the use of waste produced in different farms as feedstock for a centralized AD plant were assessed too. The results show that the levelized cost of electricity are lower for large-scale plants due to the use of more efficient conversion devices and their lower capital cost per unit of electricity produced. The levelized cost of electricity was estimated to be 4.3 p/kWh e for AD plants processing the waste of 125 dairy cow sized herds compared to 1.9 p/kWh e for AD plants processing waste of 1000 dairy cow sized herds. The techno-economic feasibility of the installation of CO 2 capture units in centralized AD-CHP plants was also undertaken. The conducted research demonstrated that negative CO 2 emission AD power generation plants could be economically viable with currently paid feed-in tariffs in the UK.
