Abstract

Biogas production in Poland and Ukraine seems to be a good way to both reduce greenhouse gas emissions and increase energy self-sufficiency by supplementing conventional energy sources. The aim of the research was to assess the potential of biogas production and the possibility of increasing it at the regional level of both studied countries and was conducted in 2018. The study included an analysis of seasonal heat demand, and the results showed biogas heat surpluses and shortages in each region. The financial side of the investment discussed using the example of the selected administrative unit showed that the construction costs of the biogas plant would be paid back after 7~9 years. The presented results also showed that Polish regions have much higher variation of biogas production potential (0.14~1.09 billion m3) than Ukrainian regions (0.09~0.3 billion m3). The analysis of the possibilities of increasing the potential based on the cultivation of maize in wastelands showed that in this respect, the Ukrainian regions have better opportunities compared to Polish regions. In the case of 20 regions, the maximum use of the potential of biogas should result in an increase in the share of renewable sources in the energy mix to above the level of 25%. Poland and Ukraine have comparable biogas production potentials of ~10 billion m3 annually, which results in a comparable number of biogas plants needed to consume that potential as well as the number of new jobs. The above analyses were also carried out at the LAU level (powiats and raions) where the potential of regional cooperation for four border regions is discussed.

Highlights

Energy is a necessary factor driving the economy both at a global and local scale, and given the progressive urbanization and growing population, the demand for electricity and heat is growing year by year
This directly contributes to the greenhouse effect, threats related to the over-exploitation of natural resources, growing social inequalities, and the degradation of natural ecosystems [1]
A smart action to avoid the situation is to increase the share of renewable energy sources in the energy mix, which would reduce the negative effects associated with the production of electricity and heat from fossil fuels while having a positive impact on the natural environment

Summary

Introduction

Energy is a necessary factor driving the economy both at a global and local scale, and given the progressive urbanization and growing population, the demand for electricity and heat is growing year by year. The vast majority of energy is produced with the use of non-renewable sources, which include crude oil, natural gas, coal, etc. This directly contributes to the greenhouse effect, threats related to the over-exploitation of natural resources, growing social inequalities, and the degradation of natural ecosystems [1]. A smart action to avoid the situation is to increase the share of renewable energy sources in the energy mix, which would reduce the negative effects associated with the production of electricity and heat from fossil fuels while having a positive impact on the natural environment. An assessment of the possibilities of cooperation in joint biogas projects carried out at the
