This paper introduces the development prospects of AVS in Hungary with insights into international trends. The most important part is a complex economic analysis and a unit cost analysis of a 38 MWp capacity AVS, considering the most typical basic data in electricity and apple production. The applied risk analysis is based on a Monte Carlo simulation, the distribution function, and probabilities. To introduce the economic facet of the competitiveness of AVS, a comparative analysis was carried out between AVS, ground-mounted photovoltaic (GM-PV) systems, and conventional apple production systems (ConAPS). In the most probable scenario, the AVS was financially attractive (NPV = 70 million EUR under 30 years). Our correlation analysis shows that feed-in tariff (FIT) price and the role of financing are considered the dominant economic factors. A favorable FIT price enhances the profitability of AVS; however, it makes GM-PV systems more profitable compared to AVS, so it negatively affects the competitiveness of AVS systems. AVS operations result in a more balanced unit cost of apples and of electricity compared to the independent operation of GM-PV systems and of ConAPS; in addition, it allows for land saving and more intensive land use.}, year = {2024}, eissn = {2071-1050}, orcid-numbers = {Chalgynbayeva, Aidana/0000-0002-9841-7765; Balogh, Péter/0000-0002-8611-0221; Szőllősi, László/0000-0003-3571-1382} } @misc{MTMT:34657932, title = {Hibrid választási modell alkalmazása a precíziós mezőgazdasági termelők drónokkal kapcsolatos preferenciájának vizsgálatára}, url = {https://m2.mtmt.hu/api/publication/34657932}, author = {Balogh, Péter and Bai, Attila and Czine, Péter}, unique-id = {34657932}, year = {2024}, orcid-numbers = {Balogh, Péter/0000-0002-8611-0221} } @article{MTMT:34528217, title = {Exploring Biomass Linkages in the Food and Energy Market - A Systematic Review}, url = {https://m2.mtmt.hu/api/publication/34528217}, author = {Igbeghe, Christian Barika and Nagy, Adrián Szilárd and Gabnai, Zoltán and Bai, Attila}, doi = {10.3390/en17030563}, journal-iso = {ENERGIES}, journal = {ENERGIES}, volume = {17}, unique-id = {34528217}, issn = {1996-1073}, year = {2024}, eissn = {1996-1073}, orcid-numbers = {Igbeghe, Christian Barika/0000-0003-0289-9876; Nagy, Adrián Szilárd/0000-0002-3813-9759} } @article{MTMT:34531317, title = {Corrigendum to ‘The monetary value of convenience and environmental features in residential heat energy consumption, in particular its social determinants’ [Energy strategy Rev.

The evaluation includes an investment analysis to present the basic scenario, a sensitivity analysis and a unit cost calculation to show the economic viability, the cost structure and the possible reserves of the synthetic natural gas (SNG) as a final output. The risk analysis is executed using Monte Carlo simulation, and the final results are the mean and standard deviation of the outputs, distribution functions and probabilities. Our results show that a significant state subsidy would be needed to boost competitiveness either in terms of investment costs (44% in our calculation) or in technology development to improve technological effectiveness. Another important competitiveness issue is the full utilization of the plant and the lowest possible price for the electricity used. If both cannot be optimized at the same time, then the first one is more important.

Kosovo can increase its self-sufficiency by taking advantage of its rich but under-utilized potential of biomass energy sources. This is a novelty study in this area, considering Kosovo lignite-dominated heat energy and electricity consumption and the available special literature. According to our estimates, the theoretical potential is 6.13 million tons/year, while the biomass energy potential should be around 4.57 million tons/year, including approximately 74.6% of biomass, which can be used for energy needs (heating and electricity). Based on the data and calculations, the available and usable potential shows biomass as an energy source with high potential in Kosovo; its share is very low, but it is reasonable to grow for both environmental and economic reasons.}, year = {2023}, eissn = {1996-1073}, orcid-numbers = {Mizik, Tamás/0000-0003-4328-0631} } @{MTMT:34181449, title = {Food, Feed and Fuel : The Place of Biomass in a Sustainable Bioeconomy}, url = {https://m2.mtmt.hu/api/publication/34181449}, author = {Igbeghe, Christian Barika and Balogh, Péter and Bai, Attila}, booktitle = {Rural society, power and social integration}, unique-id = {34181449}, year = {2023}, pages = {405-415}, orcid-numbers = {Igbeghe, Christian Barika/0000-0003-0289-9876; Balogh, Péter/0000-0002-8611-0221} } @article{MTMT:34158900, title = {The monetary value of convenience and environmental features in residential heat energy consumption, in particular its social determinants}, url = {https://m2.mtmt.hu/api/publication/34158900}, author = {Bai, Attila and Czibere, Ibolya and Kovách, Imre and Megyesi, Gergely Boldizsár and Balogh, Péter}, doi = {10.1016/j.esr.2023.101192}, journal-iso = {ENERGY STRATEGY REV}, journal = {ENERGY STRATEGY REVIEWS}, volume = {50}, unique-id = {34158900}, issn = {2211-467X}, year = {2023}, eissn = {2211-4688}, orcid-numbers = {Bai, Attila/0000-0001-9323-7311; Megyesi, Gergely Boldizsár/0000-0001-7511-8298; Balogh, Péter/0000-0002-8611-0221} } @article{MTMT:34071551, title = {A Comprehensive Review of the Distinctive Tendencies of the Diffusion of E-Mobility in Central Europe}, url = {https://m2.mtmt.hu/api/publication/34071551}, author = {Horváth, Gábor and Bai, Attila and Szegedi, Sándor and Lázár, István and Máthé, Csongor and Huzsvai, László and Zakar, Máté and Gabnai, Zoltán and Tóth, Tamás}, doi = {10.3390/en16145421}, journal-iso = {ENERGIES}, journal = {ENERGIES}, volume = {16}, unique-id = {34071551}, issn = {1996-1073}, abstract = {The study introduces the current situation of electric vehicle technologies, the possibilities and possible directions of their market, as well as the economic and environmental aspects in the eastern region of the EU, with special regard to Hungary.

The purchasing power of the population in the eastern regions of the EU is clearly lower compared to the western regions, yet people in this region spend beyond their financial means on motorization.

This phenomenon degrades the water quality and simultaneously increases the greenhouse gases emission from waterbodies resulting in climate change Inland waterbodies contain enormous amounts of nutrients such as phosphorous, nitrogen, and carbon. Thus, it becomes essential to restore these nutrients using proper sustainable approaches. Algae-based technologies have received a lot of attention these days because of environmentally friendly and inexpensive treatment. About 70% of the nutrient load from wastewater can be removed using such technology. The recovered algal biomass after wastewater treatment contains various biomolecules which can be used for the producing of value-added products such as bioenergy in the form of biomethane and biodiesel, cosmetics and pharmaceuticals along with the synthesis of nanoparticles. Therefore, the primary goal of this review is to inform readers about the possibilities of a low-cost integrated biorefinery based on microalgae for resource recovery and to mitigate eutrophication and greenhouse gas emission from water bodies.}, year = {2023}, eissn = {1587-3765}, pages = {1-12} }
