The aim of the work is to analyze the prospects for the development of bioenergy sector related to the production of second-generation aviation biofuels in the world and in Ukraine. The transport sector is a powerful source of greenhouse gas emissions. To meet the ambitious goal of achieving climate neutrality by 2050, the EU must reduce greenhouse gas emissions by 55% by 2030 from 1990 levels. According to experts, up to a third of this reduction is accounted for transport. Compared to other sectors, transport is difficult to decarbonize; this is especially true in segments such as aviation and water transport where electrification opportunities are limited. Therefore, in these segments it is necessary to move, first of all, to the use of second generation liquid biofuels. Today, the only technology for alternative aviation fuels that has fully reached the commercial level is the production of hydro-treated esters and fatty acids (HEFA). The reason for the possibility of commercialization was the development of technology for obtaining renewable diesel – hydro-treated vegetable oil (HVO). Each HVO plant can separate 15-50% of the fraction of hydro-treated esters and fatty acids, from which it is possible to obtain such aviation biofuel as synthetic paraffin kerosene (HEFA-SPK). The results of the preliminary feasibility study for the production of HEFA from false flax oil in Ukraine show that under the current conditions, such a project is not profitable given the high cost of this oil. To ensure profitable production and sale of HEFA aviation biofuel on Ukraine’s domestic market, it is necessary to work towards reducing the capital and operating costs of the project and/or introduce a temporary state subsidy for the production of sustainable liquid biofuels.
