Abstract

The purpose of the study is to analyze the current state, existing obstacles and prospects for growing and using energy crops in Ukraine. Different aspects such as the availability of unused land for cultivation, technical and economic indicators of relevant projects, as well as the results of life cycle assessment of heat production from energy crops are taken into account. Research methods include analysis and processing of official statistics on the area of land of different categories in Ukraine; performance of life cycle assessment for growing energy crops for heat production in terms of energy efficiency and reduction of greenhouse gas emissions; carrying out of feasibility study of respective projects. Results of the study show that there are up to 4 million hectares of unused agricultural land in Ukraine annually, which can be used for growing energy crops without creating competition for food production and without violating the criteria of sustainable development. The life cycle of projects for growing perennial energy crops for heat production has high energy efficiency, and the value of greenhouse gas emissions reduction depends significantly on the distance of transportation of biofuels. However, projects for the cultivation of such energy crops as willow, poplar, and miscanthus have economic indicators on the verge of profitability, and therefore may not be attractive enough for investors. Conclusions. Growing and using energy crops is one of the most promising sectors of bioenergy in Ukraine. The advantages of this area are the ability to obtain all types of biofuels (solid, gaseous, liquid biofuels) to replace traditional energy sources, a positive impact on soil (increase in organic matter, phytoremediation of contaminated lands) as well as local economic development and job creation in the regions. To improve the economic performance of the relevant projects, it is necessary to introduce a state subsidy for the cultivation of energy crops at the level of 20-24 thousand UAH per ha, depending on the type of crop.

乌克兰能源作物的种植和利用前景
该研究的目的是分析乌克兰种植和使用能源作物的现状、存在的障碍和前景。考虑到各种不同方面,例如未利用土地可供耕种的情况、有关项目的技术和经济指标以及能源作物产热的生命周期评价结果。研究方法包括分析和处理乌克兰不同类别土地面积的官方统计数据;在能源效率和减少温室气体排放方面,种植热能作物的生命周期评估绩效;进行有关项目的可行性研究。研究结果表明,乌克兰每年有多达400万公顷未使用的农业用地,这些土地可用于种植能源作物,而不会对粮食生产造成竞争,也不会违反可持续发展的标准。多年生能源作物供热项目的生命周期具有较高的能源效率,减少温室气体排放的价值在很大程度上取决于生物燃料的运输距离。然而,种植柳、杨、芒草等能源作物的项目,其经济指标已接近盈利水平,因此对投资者的吸引力可能不够。结论。种植和使用能源作物是乌克兰最有前途的生物能源部门之一。该地区的优势是能够获得所有类型的生物燃料(固体、气体、液体生物燃料)来取代传统能源,对土壤产生积极影响(增加有机质,植物修复受污染的土地),以及当地经济发展和创造就业机会。为了提高相关项目的经济效益,有必要根据作物类型,对能源作物的种植实行每公顷2 -24万瓦赫的国家补贴。
