The research examines current challenges in optimizing fuel use and conserving energy resources by analyzing various influencing factors within the framework of Uzbekistan’s “Roadmap” for industrial enterprises and consumers. The research findings indicate that the proposed hydrogen energy system can substantially improve the energy efficiency of Uzbekistan’s economy, facilitating its transition to a green economy. This research addresses issues identified in the Hydrogen Energy Roadmap by focusing on its application in vehicle operation and road infrastructure enhancement. Currently, green hydrogen contributes less than 5% of global energy production, suggesting significant potential for growth. Utilizing hydrogen in car engines improves environmental performance and ensures sustainable and abundant raw material supplies, thereby enhancing overall vehicle efficiency and reducing harmful emissions.
