This article examines how to enhance energy security in Ukraine via increased efficiency and sustainability of district heating systems (DHS). It explores the role of combined heat and power (CHP) from a technical perspective and the sustainability of the funding from a financial standpoint, plays in securing energy security. Unlike specific technical/economic studies, this provides a comprehensive overview of technologies, funding, and policies for resilient Ukrainian DHS. The study highlights the critical impact of the ongoing conflict on Ukraine's thermal energy infrastructure and the need for modernization. Preventing system collapse is cheaper and faster than rebuilding. Moreover, small but strategic investments in DHS and CHP during critical periods ensure energy system survival, preventing irreversible damage and enabling long-term recovery. The article provides an overview analysis of existing heating technologies and assesses the feasibility of integrating modern solutions such as Power-to-Heat, Waste-to-Energy and explores distributed generation (biogas/biohydrogen and hydrogen fuel) for resilient energy production in Ukraine's DHS. It further explores funding mechanisms, highlighting the importance of international financing institutions (IFI), international partnerships, state support, non-governmental organizations (NGO), and humanitarian aid roles in advancing modernization efforts. Future research assesses cogeneration effectiveness under grant funding during crises and explores distributed generation for resilience. The study highlights the CHP's potential for increasing energy efficiency, reducing emissions, and enhancing energy security. It provides policy recommendations for market liberalization and infrastructure modernization, providing a framework for Ukraine's DHS transition toward renewable energy integration and energy system sustainability. The article concludes that a strategic approach – encompassing technological, economic, regulatory, and sustainable funding advancements – is essential for the long-term sustainability of energy systems in crisis.
