Hydrogen in transport: a review of opportunities, challenges, and sustainability concerns.
Review in RSC advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This review provides a comprehensive and interdisciplinary assessment of the expanding role of hydrogen in enabling sustainable energy transitions within the transportation sector. Distinct from previous reviews, this study contributes original insights into advanced hydrogen storage technologies, integration across energy systems, and evolving policy frameworks. The review investigates the application of hydrogen in internal combustion engines, gas turbine propulsion, and fuel cell electric vehicles, with emphasis on recent progress in physical and chemical storage methods such as compressed gas, cryogenic liquid, metal hydrides, and sorbent based systems. It highlights innovations in material science and combined storage strategies that aim to improve safety, increase energy density, and reduce operational costs. Furthermore, the review explores the integration of hydrogen with renewable electricity and industrial systems, identifying its role in smart grid support, energy balancing, and flexible energy storage. The policy analysis highlights strategic national and international efforts that promote hydrogen deployment, including financial incentives, infrastructure development, and regulatory standards. The review also examines lifecycle assessment findings, comparing environmental impacts across hydrogen production routes and end use applications. Special attention is given to the role of alternative hydrogen carriers such as ammonia and liquid organic hydrogen compounds, which offer promising solutions for long distance transport and international trade. Finally, the study identifies current challenges related to technology standardization, safety regulations, and global market alignment, while outlining key research and innovation priorities essential to realizing a sustainable and inclusive hydrogen future for transportation.
