A scientometric review of blue hydrogen production.
Review in Discover energy, 2026. 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
Blue hydrogen, produced from natural gas with carbon capture and storage (CCS) is increasingly viewed as a key pathway for large-scale hydrogen supply and energy system decarbonization. This study analyzes 1432 publications indexed in the Web of Science Core Collection (WOSCC) (2000-2025) to examine the global evolution of blue hydrogen research. Bibliometric methods were applied using Bibliometrix for performance analysis, VOSviewer for collaboration and keyword mapping, and CiteSpace for cluster and trend analysis. Results show limited activity before 2010, followed by rapid growth after 2018 and strong acceleration in the past five years. China, the United States, and Europe lead in output, with growing contributions from the Middle East and South Asia. Collaboration networks indicate increasing international partnerships. Major research themes include steam methane reforming (SMR) with CCS, techno-economic and life-cycle assessments, capture and purification technologies, transport and storage logistics, and policy frameworks. Emerging topics include supply chain decarbonization, methane leakage, infrastructure planning, and carbon credit mechanisms. The findings provide a comprehensive map of trends, gaps, and future research directions in blue hydrogen.
