📄 Abstract（原文）

The paper examines the potential for modernization of urban district heating systems in Ukraine in the context of improving energy efficiency, diversifying the fuel mix, and reducing greenhouse gas emissions. In the framework of the energy sector transformation and implementation of national climate policy, modernization of district heating systems is considered one of the key directions of decarbonization of urban energy infrastructure. These issues have become particularly relevant in the process of post-war recovery of energy systems, which creates opportunities for technological upgrading of heat generation facilities through the integration of alternative heat sources. The aim of the study is to assess the potential for reducing natural gas consumption and carbon dioxide emissions through modernization of urban district heating systems based on scaling a boiler plant reconstruction model. The methodological approach is based on an energy balance model of heat production that enables estimation of fossil fuel substitution and corresponding CO2 emission reductions per unit of installed thermal capacity of alternative heat sources. International greenhouse gas emission inventory methodologies were used to assess environmental impacts. The proposed approach is applied to the district heating system of the city of Vinnytsia as a case study. Several modernization scenarios were analyzed, including the use of biomass boilers, large-scale heat pumps, and combined heat generation schemes. The study demonstrates that modernization of district heating systems can significantly influence the fuel structure of heat generation, contribute to diversification of energy sources, and improve the resilience of urban energy systems. A preliminary assessment of scaling the obtained results to the national level indicates a considerable potential for reducing natural gas consumption in the Ukrainian heating sector. The proposed approach can be used as a decision-support tool for planning modernization of urban district heating systems, developing heat infrastructure programs, and designing decarbonization strategies for the heating sector. Keywords: district heating, modernization of heating systems, alternative heat sources, biomass, heat pumps, decarbonization, CO2 emission reduction.
