Item Comparison financing conditions of the development biogas sector in Poland and Ukraine(International Journal of Ecology and Development, 2015) Cebula, Jan; Пімоненко, Тетяна Володимирівна; Пимоненко, Татьяна Владимировна; Pimonenko, Tetiana VolodymyrivnaУ статті аналізуються умови розвитку відновлюваних джерел енергії в енергетичному секторі Польщі та України. Аналіз європейського досвіду показує, що світові лідери збільшують частку відновлюваної енергії в загальному енергоспоживанні. Вони створюють сприятливі умови для розробки, фінансування та реалізації екологічних проектів використання альтернативних джерел енергії. Крім виробництва та використання біогазу, енергія є однією з важливих галузей відновлюваної енергетики у світі. У статті проаналізовано економічний ефект біогазового проекту в Польщі та Україні. Автори систематизують основні інструменти та механізми стимулювання розвитку біогазової галузі.Item Methane fermentation of pomace wastes generated in cereal coffee production(2015) Богжевіч, Ж.; Цебула, Ж.; Пріотровскі, К.; Сакевіч, П.; Прізвара Л.; Пімоненко, Тетяна Володимирівна; Пимоненко, Татьяна Владимировна; Pimonenko, Tetiana VolodymyrivnaBatch methane fermentation of pomace wastes from cereal coffee production was experimentally studied. Data were elaborated with modified Gompertz kinetic model. The 10-time increase in reactor load 5-50 g/dm3 corresponds to proportional growth of maximal biogas yield Hmax from 421.94 to 4119.37 cm3 and growth of maximum process rate Rmax from 1.0745 to 10.7379 cm3/h. Unit reactor yield (for 1 g of raw mass, dry mass and dry organic mass) decreases, however, with increase in reactor load within 5-30 g/dm3 range while unit maximum process rate turned out to be practically load-independent.Item Biogas as an alternative energy resource for Ukrainian companies: EU experience(LLC “Consulting Publishing Company “Business Perspectives”, 2018) Yevdokymov, Yu.; Чигрин, Олена Юріївна; Чигрин, Елена Юрьевна; Chygryn, Olena Yuriivna; Пімоненко, Тетяна Володимирівна; Пимоненко, Татьяна Владимировна; Pimonenko, Tetiana Volodymyrivna; Люльов, Олексій Валентинович; Люлев, Алексей Валентинович; Liulov, Oleksii ValentynovychThe paper deals with analysis of the preconditions of alternative energy market development in Ukraine. In this case study, the authors analyzed the EU experience. The results of analysis showed that the leader of the EU countries in renewable energy has already achieved the target (20%), which had been indicated. In addition, the findings showed that the share of renewable energy in gross final energy consumption has been increasing from year to year. The authors allocate that, according to the Ukrainian potential, biogas is the most perspective one among alternative resources. Moreover, results of analysis showed that Ukraine has the huge potential of agricultural sector. In this direction, the authors allocated the main types of the agricultural activities, which have the highest potential of biogas production: sugar factories, corn silage and poultry farms. The authors underlined that biogas spreading is restrained by the stereotypes that green investments are not attractive for investors. In order to analyze the economic efficiency of investments to the biogas installation, the authors calculated the profit from the biogas installation for poultry farm. The authors made two scenarios for calculation. The first – the whole volume of energy, which was generated from the biogas unit, will be sold with feed-in tariff. The second – the farm covers its own needs in electricity, the rest will be sold with feed-in tariff. The findings showed that the first scenario is more attractive. Moreover, the farm could receive higher profit if it installed the biogas in 2016, not in 2017. In addition, based on the EU experience and features of farm functioning, the authors approved that the biogas installation has not only the economic effect (profit and additional profit) for company, but also ecological and social effects for rural area, where this farm was located.
