The article examines the normative monetary valuation of agricultural land in the regions of Ukraine. The dynamics of change of sown areas of the main agricultural crops is analyzed. The directions of the development of agricultural production in the short term are determined. The main components of biomass energy potential in Ukraine are studied – agricultural residues (straw of cereals and rapeseed, by-products of corn and sunflower production) and energy crops (willow, poplar, miscanthus for solid biofuels and corn silage for production). It is determined that in the structure of energy production from biomass in Ukraine, agricultural residues and energy crops occupy the last places, as their potential is used by 0.1-3.0% depending on the type of biomass. The necessity of creating of energy cooperatives in rural areas focused on the production of solid biofuels from crop waste has been proved. The prospects for the development of bioenergy outlined in the «Roadmap for the development of bioenergy until 2050 and the Аction plan until 2025» are studied and the forecast of the development of the energy potential of biomass is made. It is determined that despite a significant number of existing regulations related to the development of biofuels, measures to support biofuel producers include only two instruments: a «green» tariff for electricity produced from renewable energy sources (including biomass / biogas), and stimulating tariff for thermal energy, produced from alternative energy sources (including biomass / biogas). Barriers to the development of biofuels production and possible ways to overcome them have been studied. The need to create bioenergy clusters to stimulate the production of biofuels has been identified. Measures to improve state regulation and support the production of biofuels are summarized. It is proved that at the state level it is necessary to constantly motivate agricultural producers to produce different types of biofuels. The main directions of the strategy of biofuel production development in the conditions of land relations reform are substantiated.

Nigeria is a developing country with an insufficient supply of energy to meet the continuously growing demand. However, there are several biomass resources available within the country. This paper presents a desk review, which investigates the potential resources for biomass energy generation within the country. Energy policies to aid biomass use as an energy source within the country were also reviewed. Biomass resources identified within Nigeria include forest residues, agricultural residues, human and animal wastes, aquatic biomass, and energy crops. However, several of the resources, particularly agricultural residues, have competing uses, such as livestock feed and soil rejuvenation. An estimation of the technical energy potential of the biomass resources revealed that about 2.33 EJ could be generated from the available resources in Nigeria. Agricultural residues have an energy potential of about 1.09 EJ, with cassava, maize, oil palm, plantain, rice, and sorghum being the major contributors. Animal wastes, municipal solid waste, and forest residues have energy potentials of 0.65, 0.11, and 0.05 EJ, respectively. The potentials of wood fuel and charcoal are 0.38 and 0.05 EJ, respectively. The study found that despite the available potential and existing policies, not much has been done in the implementation of large-scale bioenergy within the country. However, there has been laboratory and research-scale investigations. The review suggests that more policies and stronger enforcement will aid bioenergy development within the country. From the review, it has been suggested that the agricultural sector needs to be developed to generate more biomass resources. More research, development, and implementation have to be carried out on biomass resources and bioenergy generation processes. The production of non-edible energy crops in marginal lands should also be considered prime to the development of bioenergy within the country.

AbstractDespite enormous challenges in accessing sustainable energy supplies and advanced energy technologies, Ethiopia has one of the world's fastest growing economies. The development of renewable energy technology and the building of a green legacy in the country are being prioritized. The total installed capacity for electricity generation in Ethiopia is 4324.3 MW as on October, 2018. Renewable energy accounts for 96.5% of total generation; however, despite the county's enormous biomass energy potential, only 0.58% of power is generated using biomass. Ethiopia has surplus woody biomass, crop residue and animal dung resources which comprise about 141.8 million metric tons of biomass availability per year. At present the exploited potential is about 71.9 million metric tons per year. This review paper provides an in-depth assessment of Ethiopia's biomass energy availability, potential, challenges, and prospects. The findings show that, despite Ethiopia's vast biomass resource potential, the current use of modern energy from biomass is still limited. As a result, this study supports the use of biomass-based alternative energy sources without having a negative impact on the socioeconomic system or jeopardizing food security or the environment. This finding also shows the challenges, opportunities and possible solutions to tackle the problem to expand alternative energy sources. The most effective techniques for producing and utilizing alternate energy sources were also explored. Moreover, some perspectives are given based on the challenges of using efficient energy production and sustainable uses of biomass energy in Ethiopia as it could be also implemented in other developing countries. We believe that the information in this review will shed light on the current and future prospects of biomass energy deployment in Ethiopia.

Development of the world economy requires energy supply, which under stable growth must be based on alternative energy resources. Bioenergy is an integral part of energy security supply in volatile countries. It can satisfy a considerable part of energy demand of agribusinesses and other companies as well as facilitate problem-shooting in energy, ecological and social sectors in some regions. Enhancing bioenergy in Ukraine is one of the strategic ways in the development of the alternative energy sector, taking into account high volatility of the country and significant potential of biomass available for energy production. This research intends to determine conditions and mechanisms of development and functioning of bioenergy clusters based on preliminary specification of the bioenergy potential of the territories, taking into account modern marketing approaches. This article contains evaluation of the bioenergy production growth in countries such as China, Germany, France, the USA, Canada, Brazil and Ukraine. The feasibility of the cluster approach for Ukrainian bioenergy development has been proved. In order to combine Ukrainian regions according to all types of energy resources the authors applied the method of clustering analysis. The key point of the method implies that, based on the given set of indicators which are defined as the main characteristics of the object, every object of the population belongs to a similar class. Therefore, in order to study the efficiency of usage of bioenergy resources in a particular region, it is necessary to classify a set of indicators to identify standard forms. To systemize Ukrainian regions, the Isodata algorithm Isodata, based on the types of the economic and energy potential of biomass, is taken into account. To implement the analysis, the following indicators are considered: the biomass energy potential of primary cell waste, the biomass energy potential of trimming, the biomass energy potential of refining, the energy potential of wooden biomass, the mold biomass potential, the energy potential of bioenergy crops, the corn energy potential (biogas). Market players organize groups with regard to their industries, territories and other factors, namely clusters which are likely to become effective tools in while carrying out scale projects under tough competition. In the minor energy sector cooperation between research and manufacturing enterprises, which satisfies energy needs both of cities and individual customers, is growing. This approach perfectly meets all requirements of the regional development of Ukrainian bioenergy. The main goal of bioenergy clusters is to develop competitive advantages of regions by increasing all types of biomass and biofuel production. This implies the following priorities: creation of a database of agribusiness enterprises, which potentially are members of the cluster and corresponding infrastructure, establishment of marketing communications in order to inform members and potential investors about bioenergy advantages, introduction of regional databases by means of webpages, newsletters, public discussions etc., enhanced vocational training of bioenergy industry employees and investment attraction to finance bioenergy projects. As a result, the authors of the paper propose a classification of Ukrainian regions based on the indicators of the economic energy potential of wastes and energy crops in agribusinesses, which is the basis for cluster formation. Vinnytsia, Kyiv, Poltava, Sumy, Khmelnitsky and Chernihiv regions refer to the first type with the biggest bioenergy potential, which makes it possible to create 2 energy clusters by combining central-west and north-east regions. Such a methodology gives an opportunity to satisfy the needs of the regions and districts which need additional energy resources taken from own biomass. Priority tasks of the bioenergy cluster include: development of the database of agribusiness entities which potentially are the cluster members and corresponding infrastructure, informing members and investors about bioenergy benefits, creation of the regional information database identifying the resources, capacity and the transport system, vocational training, investment attraction in order to implement bioenergy projects. Based on clusters, economic relations build up a competitive and sound investment climate to support the economy, which, in turn, provides high living standards. The authors have defined the procedure for exercising the cluster initiative and determined the structure of marketing support for cluster projects.

Solid Biomass

Conventional energy sources often do not fully satisfy the needs of a modern economy, especially given the climate changes associated with them. These issues should be addressed by diversification of energy generation, including the development of renewable energy sources (RES). Solid biomass will play a major part in the process in Poland. The function of rural areas, along with a well-developed agricultural and forest economy sector, will be a key aspect in this as these areas are suitable for solid biomass acquisition in various ways. This study aimed to determine the solid biomass energy potential in the commune of Goworowo to illustrate the potential in the smallest administrative units of Poland. This research determined the environmental and natural conditions in the commune, which helped to identify the crucial usable solid biomass resources. The total energy potential of solid biomass resources in the commune of Goworowo amounted to 97,672 GJ y−1. The highest potential was accumulated in straw surplus (37,288 GJ y−1) and the lowest was in wood from roadside maintenance (113 GJ y−1). This study showed that rural areas could soon play a significant role in obtaining solid biomass, and individual communes could become spaces for the diversification of energy feedstock.

The transition to alternative energy sources requires a long period, attracting significant investments in the process of creating and developing environmentally friendly fuels. Creating an environmentally safe, energy-efficient economy is a prerequisite for sustainable development of each country. The above-mentioned factors determine the relevance of the study of the problems of the functioning and development of energy, which is mainly due to the economic expediency of renewable energy and the requirements of the country's energy independence. The objective of the article is to determine the features of ensuring the energy efficiency of the Ukrainian economy using alternative energy sources. Research shows that the development of alternative energy will allow us to move away from the use of traditional fuels and create the prerequisites for the energy independence of countries. Taking into account the natural factors and the significant dependence of Ukraine on imported primary energy sources, it is determined that solving the problem of increasing energy efficiency of the economy is possible only with the stimulation of the use of alternative energy sources. The most promising sources of energy are identified, namely: biofuels, wind energy, geothermal energy, solar energy, solar thermal, controlled thermonuclear fusion, energy of tides and effluents. The recommendations for realization of such directions of the policy of the state regulation in the energy sphere as energy security, energy efficiency, energy saving are given.

Purpose of the study is to assess the current and prospective energy potential of agribiomass (agricultural residues and energy crops) in Ukraine, to determine its main components and the most effective areas of their use. Methods. The assessment of the current potential of agribiomass is performed using official statistics on crop production in Ukraine. Based on these data, the total amount of crop residues formed and their share available for energy needs is determined. When assessing the potential of energy crops, it is assumed that they are grown on 2 million hectares of unused agricultural land, the total area of which is up to 4 million hectares in Ukraine. The study of the prospective potential of biomass is performed for 2050, based on key growth factors, such as increasing yield of crops, especially cereals; doubling the area under energy crops and increasing their yields, etc. Results of the assessment show that according to 2018 data, the total bioenergy potential in Ukraine is more than 23 Mtoe (the economic potential). Its largest components are agricultural residues (44%) and energy crops (32%). Expert estimates suggest that by 2050, the biomass potential could increase to more than 47.5 Mtoe/yr, in other words almost to double. Forecasting the structure and directions of use of biomass potential by 2050 shows that about 20 Mtoe of biomass/biofuels of the following types will be consumed for energy: wood biomass, primary and secondary agricultural residues, energy crops, biogas/biomethane from different types of raw materials, liquid biofuels (biodiesel, bioethanol). Conclusions. Areas of use of biomass/biofuels include the production of heat and electricity from solid biofuels, obtaining of biogas and biomethane, as well as the production of motor biofuels (biomethane, biodiesel, bioethanol). In the near future, it is considered necessary to develop a long-term strategy for the development of bioenergy in Ukraine, taking into account results of the study. In turn, the basic figures of the bioenergy development strategy can be used for the elaboration of the updated Energy Strategy of Ukraine until 2050.

Potential depletion of fossil fuel and climate change have globally accelerated the demand in renewable and alternative energy. Most of the Southeast Asian countries have an abundance of biomass sources for the energy sector due to their agriculture-based economy and enormous forest resources. Therefore, the study aimed at highlighting an overview of biomass energy in the Southeast Asia countries to convey the environmental and economic benefits from the available biomass sources in the region. In order to achieve the aim, the study synthesized and evaluated the biomass sources, energy potential, utilization, and management in the region, based on the published research papers, review papers, and country reports. It was found that the major biomass sources in this region were fuelwood, wood residues, rice husk, rice straw, sugarcane residues, oil palm residues, and coconut residues. The total annual quantity of the biomass potential from agriculture and forest sector in the region was estimated at more than 500 million tons per year and equal to over 8000 million gigajoules of total energy potential. In order to implement the sustainable utilization of biomass sources, the study specified the barriers and challenges of biomass utilization in these countries and proposed a sustainable approach of biomass energy, by comparing the way of traditional biomass utilization.

The article analyzes the procedure of buying the electricity according to the feed-in-tariff (FIT) and the model («Typovyi») Power Purchase Agreement, in connection with the introduction of a new electricity market and the order of Renewable producers` business. Specific features of the model Power Purchase Agreement conclusion between Renewable producers and the Guaranteed Buyer are defined. It also analyzed the differences between the model Power Purchase Agreement and the oriental agreement as well as researched a mechanism of investors protection who would invest in the Renewable projects. The authors of the article have made a comparative analysis of the different Power Purchase Agreement`s editions, in particular: actual model agreement form and oriental agreement according to which the Renewable producers are no longer work but the provisions contained therein make it possible to analyze the process and the reasons for adoption of the new one form. Effectiveness of a new electricity market introduction from July 1, 2019 depends on the regulation of the activities for all the market participants. Special operating conditions have been provided for the Renewable electricity producers. In particular, with the introduction of a new market, Renewable electricity producers began to sell electricity to the Guaranteed Buyer, the successor of the SE «Energorynok». However, in order to implement the new procedure of work for the Renewable producers, the Regulator needed to approve certain regulatory acts. With this purpose, in September 2018, the National Commission for State Regulation in the Fields of Energy and Utilities published a draft resolution «On approval of regulatory acts regulating the activity of a guaranteed buyer and purchase of electricity at feed-in-tariff», which contained the form a new model contract for the sale of electricity at feed-in-tariff between a Guaranteed buyer and an entity that produces electricity using alternative energy sources as well as the order of purchase and sale of electricity at FIT. As rightly expected, the approval of these regulations is an important element not only for functioning of the new electricity market, but also for the continued growth of electricity production from renewable energy sources and attracting international investments.

Fast Growing

Energy crops are grown for energy purposes. Traditionally energy crops are corn and sugarcane which are grown for industrial scale ethanol, rapeseed for producing biodiesel, annual and perennial grasses, for example cane, miscanthus, cereal straw, as well as fast-growing tree crops for biomass production. The most interesting for the temperate climate zone of Europe are the fast-growing willow species. The interest in growing energy crops, which can be used as a renewable energy source, in European countries arose in the 1970s, which was related with rising prices for traditional energy sources. The growth of energy crops has been fueled by political decisions at the international level, in particular by documents such as the Renewable Energy Development Plan for Europe and the Kyoto Protocol. After some recession, landing areas for energy crops in the EU and North America have been stabilized. The fastest growing willow occupies the largest area in Europe. The average yield of willow wood in our experiments was about 50 tons per hectare at a moisture content of 45%, with a three-year biomass harvest cycle or 9.2 tons per year and dry matter from 9 to 15 tons per year per dry biomass, in depending on the conditions of cultivation, soil, clone. The weighted average cost of one ton of willow wood with a moisture content of 10% at an area of 100 hectares of plantation for its lifetime (22 years) will be $ 30.5. The cost of growing willow, transporting and shredding timber at a plantation area of 30 hectares is about $ 510 per hectare. About half of all biofuel production costs are depreciation deductions for the operation of special planting and harvesting equipment. The expansion of the plantation area 3–4 times compared to the base variant (30 hectares) allows to increase the profitability of energy production by 30–50%. The return on initial costs required to organize a willow plantation depends on the use of biomass. When replacing wood with traditional energy sources (natural gas), according to our calculations, the simple payback period is 3.8 years and the discounted time is 4.7 years, which corresponds to the time of harvesting the first biomass crop. With the direct sale of biomass on the market in the payback period increases to 6–11 years, which corresponds to the second or third harvesting period (with a three-year cycle). The unit cost of energy derived from willow wood is lower relatively to other energy crops, but 1.5 times and 1.8 times higher than that of natural marsh vegetation and straw, respectively. However, the additional interest in planting willow is due to their conservation value. The main indicators for calculating cost-effectiveness have been taken experimentally. The higher combustion heat of the above-ground part of the willow tree stand averaged 18500 kJ/kg. This is in line with the results obtained by other researchers for willow wood. The maximum specific heat of combustion of willow wood according to the results of experiments carried out in Sweden ranged from 18.3 to 19.7 MJ/kg, depending on the harvesting time and the willow clones. Therefore, we can confidently say that to grow energy willow is expediently and cost-effectively.
