Abstract:The aim of the analysis is to present the implementation and development of agricultural biogas plants as a chance for diversification of agriculture in Poland. The main exogenous and endogenous determinants of the development of agriculture biogas plants in Poland were indicated. It is an attempt to present agricultural biogas plants in terms of their spatial distribution as well as the installed capacity and efficiency of agricultural biogas installations. Moreover, the feedstock structure for agricultural b… Show more

The aim of the study was to evaluate the usefulness of sugar beet for biogas production, taking into account the duration time of storage and sugar content in the roots. The research has included analysis of methane and biogas yield of sugar beet. The relations between the sugar content in the roots and the length of storage period and the course of the methane fermentation process were determined. Sugar beets with sugar content of 17.6% and 19.6% were used for this experiment. In order to analyse the fermentation process, the fresh beets and the beets stored in flexible, hermetic tanks in the period of 43 and 89 days were used. Based on the analysis of the obtained results, it was found that the sugar content and the storage time of sugar beet roots can differentiate the production of biomethane and that it influences the methane fermentation process and the quality of the produced biogas.
“…Many papers present the analyses of the production of agricultural biogas plants, their installed power capacity, institutional conditions, as well as endogenous and exogenous factors determining the establishment of agricultural biogas plants including structure of substrates for biogas production or funds for investment (e.g., Weiland, 2003;Lantz et al, 2007;Masár and Božík, 2009;Budzianowski, 2012;Chodkowska-Miszczuk and Szymańska, 2013;Kiedrowicz et al, 2013;. Other frequently discussed issue is associated with the social and economic factors affecting the implementation of biogas projects, the selection of technology, the size of ABPs, etc.…”
Abstract.Energy production by agricultural biogas plants has recently recorded considerable growth in Visegrad countries. The development was enhanced by European Union's efforts to increase the proportion of energy produced from renewable sources. The paper aims to assess the role of energy policy in the development of agricultural biogas energy production in Visegrad region. Conducted studies have shown that among various forms of support for energy production from renewable energy sources, the price system prevails, including the support by feed in tariffs and bonuses. Feed in tariffs were adopted in Czech Republic, Hungary and Slovakia. Another kind of support system -a quota system -was adopted in Poland, what includes tendering and certificate systems. The results confirm the adoption of legal framework was necessary step to enable agricultural biogas energy production in Visegrad countries, but itself it was not enough to stimulate development of agricultural biogas energy production significantly. Rapid development in each country was recorded only after the certain financial support systems took effect, what made production of agricultural biogas energy economically efficient for investors. The production of energy from agricultural biogas grew the most in the Czech Republic and Slovakia, where the financial support was the highest. Nevertheless, the protracted process of changes in legal framework and transformation of energy policy, certain measures including state-controlled price-making systems, risk regarding with auction system might hamper agricultural biogas energy production further development.
