Traditional internal combustion engines (ICEs) have garnered considerable attention due to their high emissions and low efficiency issues. In this study, a novel ICE–fuel cell hybrid power system based on single‐methanol fuel is proposed address these concerns. The utilizes methanol as fuel, directly supplying it the engine, generates hydrogen for through reforming technology. structural design of fully exploits engine exhaust, first using waste heat produce then utilizing exhaust inertial potential energy drive dual turbocharging structure air compression entering cell, thereby achieving self‐thermal balance. Thermodynamic analysis cost evaluation indicate that thermal improved by 8.34% compared traditional diesel setups. Compared engine‐fuel systems do not utilize heat, increased 5.81%. terms economics, ≈.1466$ , which 44.05% lower than 0.262 $ systems. This study presents an innovative solution significantly enhances offers economic advantages, providing viable approach issues ICEs.

Nowadays, the combustion of fossil fuels for transportation has a major negative impact on environment. All nations are concerned with environmental safety and regulation pollution, motivating researchers across world to find an alternate fuel. The transition sector towards sustainability can be achieved by manifestation commercialization clean hydrogen Hydrogen fuel sustainable mobility its own effectiveness in terms generation refueling processes. As requirement vehicles cannot anticipated because it depends utilization, choosing onboard point concern. This review article describes present status utilization particular focus industry. advantages internal discussed. In performance, affordability, lifetime, hydrogen-generating subsystems must compete what automobile manufacturers consumers have seen modern date. engines, various benefits combustive properties, but needs careful engine design avoid anomalous combustion, which is difficulty engines. Automobile makers buyers will not invest cell technology until technologies that make up components advanced acceptable levels cost, reliability, durability, safety.

Energy is often described as the lifeblood of a nation’s economy, and world energy trilemma calls for collaboration innovative solutions at national level. This where Education Sustainable Development (ESD) plays crucial role, helping integrate achievement United Nations Goals (SDGs) while addressing challenges posed by trilemma. Europe’s strong commitment to transitioning sustainable evident in its response geopolitical changes climate targets. Notably, Baltic States have taken decisive action war Ukraine, choosing completely halt electricity imports from Russia Belarus. shift was supported increased via interconnectors Finland, Sweden, Poland, with rising 13,053 GWh—an increase 2.6% 2023 compared previous year. Latvia, which holds highest green potential Sea region, has nevertheless lagged behind counterparts terms implementation. In 2021, Latvia ranked third among European Union (EU) countries renewable share final consumption, 42.1%, significantly higher than EU average 21.8%. However, further progress needed meet Latvia’s 2030 target 14% use transport.

Considering unpredictable and hastily evolving tipping points (like the impacts of COVID-19 pandemic, ongoing climate crisis war in Ukraine), it is clear that sustainable energy transition utilization locally sourced renewable energies must be heart both national, regional, local systems. However, if we take a closer look at actions undertaken (communal) level, see enormous diversity patterns, prerequisites, implications drive affect spatial deployment energies. Therefore, our research targets to better comprehend question individual communities are comparatively involved transition. We also ask whether demand supply territorially balanced how these differences (if any) can justified. framing by concepts justice ecological debt. thoroughly explore asses balance on level which based data installed power capacity potentials consumption administration units Poland (380).
