Applications of Renewable Energies in Low-Temperature Regions: A Scientometric Analysis of Recent Advancements and Future Research Directions

Energies, Journal Year: 2025, Volume and Issue: 18(4), P. 904 - 904

Published: Feb. 13, 2025

This study presents a scientometric analysis of renewable energy applications in low-temperature regions, focusing on green hydrogen production, carbon storage, and emerging trends. Using bibliometric tools such as RStudio VOSviewer, the research evaluates publication trends from 1988 to 2024, revealing an exponential growth studies post-2021, driven by global policies promoting neutrality. Life cycle assessment (LCA) plays crucial role evaluating environmental impact systems, underscoring need integrate sources for emission reduction. Hydrogen production via electrolysis has emerged key solution decarbonizing hard-to-abate sectors, while storage technologies, bioenergy with capture (BECCS), are gaining traction. Government policies, including taxes, fossil fuel phase-out strategies, subsidies, significantly shape transition cold regions incentivizing low-carbon alternatives. Multi-objective optimization techniques, leveraging artificial intelligence (AI) machine learning, expected enhance decision-making processes, optimizing efficiency, reliability, economic feasibility systems. Future must address three critical challenges: (1) strengthening policy frameworks financial incentives large-scale deployment, (2) advancing hybrid (3) integrating multi-objective approaches cost-effectiveness resilience extreme climates. It is that will contribute field knowledge regarding regions.

Mapping Green Hydrogen and Renewable Energy Research in Extended BRICS (Brazil, Russia, India, China, South Africa and Others): A Bibliometric Approach with a Future Agenda

Hydrogen, Journal Year: 2025, Volume and Issue: 6(2), P. 33 - 33

Published: May 6, 2025

Green hydrogen has emerged as a critical pillar of sustainable energy transitions, with its potential carbon-free fuel to decarbonize hard-to-electrify sectors while bolstering security. This study examines the trajectory green and renewable research within extended BRICS nations (the five core plus recent entrants) using bibliometric analysis, aiming map publication trends, thematic focus, collaborative networks from 2005 2024. A comprehensive dataset 292 publications (2005–2024) was retrieved Scopus. The results reveal rapidly growing body literature an accelerating output in years substantial citation impact. China leads both volume influence, followed by India Russia, attesting robust national initiatives. Approximately one-quarter studies involve international co-authorship, underlining active collaboration among these countries beyond. novelty this lies conducting first analysis BRICS, highlighting patterns, evolution inform future policy development. These insights offer valuable guidance for policymakers industry stakeholders strengths (hydrogen production technologies) pinpointing gaps where capacity-building is needed.
