From Source to Street – Regional Energy Efficiency of Mobility Systems is a sustainability-focused analytical project developed to provide a comprehensive evaluation framework for modern mobility technologies through a regional energy-efficiency perspective.

The project addresses a key challenge in the transition toward sustainable transportation: the absence of a universally applicable method for comparing the real-world efficiency of Internal Combustion Engine (ICE) vehicles, hybrids, Battery Electric Vehicles (BEVs), hydrogen-powered vehicles, CNG systems, and synthetic fuel technologies. The efficiency and environmental performance of these solutions vary significantly depending on regional factors such as electricity generation mix, infrastructure maturity, fuel production pathways, and seasonal climate conditions.

To address this challenge, an interactive Well-to-Wheel dashboard was developed specifically for the Hungarian energy and transportation ecosystem. Rather than evaluating vehicles in isolation, the platform maps the entire energy conversion pathway—from energy production, processing, and storage to drivetrain operation and final wheel output. This approach enables users to better understand the real efficiency of different transportation technologies within a specific regional context.

A major component of the project involved seasonal and scenario-based analysis, examining how Hungary’s winter, spring, summer, and autumn conditions affect the performance of various mobility solutions, particularly battery-electric and hydrogen-based systems. The project also proposed a collaborative framework that would allow accredited institutions and researchers to continuously update efficiency data as technologies evolve.

By transforming complex mobility and energy data into an accessible and interactive decision-support tool, the project contributes to more transparent, data-driven, and sustainable transportation planning for the future.
