“…A study done in reference [9] projected the hydrogen production potentials from surplus hydro energy in Nepal for several scenarios for the study period (2022-2030). According to the study, the hydrogen production potential in 2030 ranges from 63,072 tons to 3,153,360 tons, with 20 percent and 100 percent surplus energy usage, respectively as shown in Figure 6 [9]. The same data is utilized to project the ammonia production potential from hydrogen and surplus hydro energy for Nepal.…”

“…A similar study was done by Biraj Singh Thapa and et.al in 2021, which showed hydrogen production potential from surplus hydroelectricity in Nepal in different scenarios and its application in different end uses areas. The study projected that around 3.1 million tons of green hydrogen from hydropower could be produced given that 100% utilization of surplus energy is used [9]. M.S Zaman and A.B.…”

An increase in the installed capacity of Hydroelectricity in Nepal in 2022 by 122% compared to that in 2021 is a major milestone in power production in the country. This increase in electricity production will make the country self-sufficient in electricity for the first time in the last three decades. The future growth of hydropower installations in Nepal is expected to rise much beyond the local consumption and is forecasted to reach as much as 3500 MW surplus energy by 2028. Most of the hydropower projects built and under construction are run-off -river type, due to which the power generation is highly seasonal and results in the poor load factor. There is a need for Nepal to plan the effective use of surplus power and the seasonality variation of hydro-energy. Producing green ammonia from hydroelectricity and its utilization in industries and commercial sectors can be one of the options for the storage and transportation of surplus hydroelectricity in Nepal in the future. With the flexibility of usage, and given the fact that the required technologies and infrastructures for safer transportation, distribution, and ammonia application are already in place; ammonia can be a viable option to be a hydro-electricity carrier of the future in Nepal. This paper studies the potentials of ammonia as a hydroelectricity carrier and its application as a chemical commodity in the industries and transportation sector. The different chemical attributes of ammonia along with the production technologies, economies of ammonia production, storage, transportation, and its subsequent application are studied. This study concludes that utilization of ammonia as a hydro-energy carrier and its usage as a chemical commodity in the industries, green fuel in the transportation sector can be a good opportunity to lead the country towards sustainable and renewable energy economy.

“…Jana Hojnik et al identified that the main obstacle in the development of information and innovative cities is the lack of financial resources for simultaneously planned restructuring, which also requires a transition to green energy, but the population positively perceives such transitions, and is able to "take on" the green energy payments [8]. Biraj Singh Thapa et al analyzed the methods of energy conservation and concluded that the use of hydrogen is expedient and cheaper than traditional methods of generating energy; therefore, this direction is promising in the Ukraine [9]. Beth Davis-Sramek notes that state policy on the rational use of natural resources plays an important role.…”

“…Business competition has led to the emergence of new goods, more packaging materials, and new production facilities in unoccupied (urban) areas-a reflection of anthropogenic effects. In the Ukraine, there is corruption, inadequate fines, and minimal control over compliance with the law [9]. Environmental passports are bought and sold; corruption exacerbates these effects [10].…”

For the Ukrainian population, there are factors surrounding the choices and preferences one must consider when changing permanent residence. Smart residential areas should be built according to Ukrainian legislation and global innovations, which would reduce administrative dislocations, the load on megalopolises, and negative anthropogenic impacts, and should be based on the increase in energy efficiency and reducing waste. We analyzed the core principles of designing smart residential areas and concluded that constructing cutting-edge residential areas should involve private investments in order to avoid shadow schemes and irrational use of funds (in the Ukraine, the share of the shadow market is more than 50%). Research shows that, as humans inhabit a three-dimensional space, it is possible to predict migration and other permanent residence/behavioral responses, the analysis of which allows controlling migration flows and improves the conditions of Ukraine’s small residential areas based on decarbonization. We conclude that energy saving systems can reduce consumption in a city by 60% and improve Ukraine’s ecosystem. Research also shows that reducing “dislocation”, in terms of population density, by creating open, innovative, eco-friendly environments based on green economy principles, can provide innovative development maps and economic, social, and cultural population growth, decreasing the load on big cities/regional economies, and encourage the restoration of sales markets and production after the COVID-19 pandemic. We developed a model to assess the innovativeness of residential areas, apply alternative methods of energy generation, and analyze the impact of the energy production and consumption market in Europe (with recommendations for the Ukraine). This article estimates energy intensity indicators of the gross domestic product in the Ukraine and in Europe, offering methods to decrease energy dependence and increase energy efficiency in the Ukraine, by adopting alternative energy sources (e.g., biohydrogen out of residues, air, and solar energy), and enhancing environmental legislation.

“…"Green hydrogen" shows better environmental performance since no CO 2 is produced but it suffers from higher costs [11]. Thapa et al [12] studied the potentials of hydrogen production from hydropower plants in Nepal aiming to replace fossil fuels in road transport sector. An estimation of the surplus energy in the years to come was made relying on current data from the national authority.…”

The production of “green hydrogen” is currently one of the hottest topics in the field of renewable energy systems research. Hydrogen storage is also becoming more and more attractive as a flexible solution to mitigate the power fluctuations of solar energy systems. The most promising technology for electricity-to-hydrogen conversion, and vice versa, is the reversible solid-oxide cell (SOC). This device is still very expensive, but it exhibits excellent performance under dynamic operating conditions compared to the competing devices. This work presents the dynamic simulation of a prototypal renewable plant combining a 50 kW photovoltaic (PV) field with a 50 kW solid-oxide electrolyzer cell (SOEC) and a compressed hydrogen tank. The electricity is used to meet the energy demand of a dwelling located in the area of Campi Flegrei (Naples). The SOC efficiency is simulated by developing a mathematical model in MATLAB®. The model also calculates the cell operating temperature as a function of the input current. Once the optimal values of the operating parameters of the SOC are calculated, the model is integrated in the transient system simulation tool (TRNSYS) for dynamic analysis. Furthermore, this work presents a parametric analysis of the hydrogen storage system (HSS). The results of the energy and environmental analyses show that the proposed system can reach a primary energy saving by 70% and an amount of saved CO2 of 28 tons/year. Some possible future market scenarios are considered for the economic analysis. In the most realistic case, the optimal configuration shows a simple pay back lower than 10 years and a profit index of 46%.
