a scientometric review of green technologies in the steel industry

Scientometric analysis of green technologies in the steel industry is crucial for reducing co2 emissions, as the steel sector contributes 7-9% of global greenhouse gases. this study identifies trends and research gaps to improve strategic decision-making and promote green technologies in the industry. using the google scholar database, scientific studies related to green steel and various topics were reviewed. keywords were identified through literature studies and expert interviews, and primary data on science, technology, and innovation policies in the steel industry from 2000 to 2024 were extracted using publish or perish software. a total of 14,992 records were analyzed, accumulating 10,663,295 citations. the most cited keyword was &life cycle assessment& with 1,382,792 citations, while &hydrogen-based steelmaking& had the fewest. data such as author name, publication year, title, and citation count were gathered, and a knowledge map was created using vosviewer software. this research, reviewing nearly 15,000 studies over 24 years, provides insights into trends, strengths, weaknesses, and emerging research areas in the field. key topics include life cycle assessment, china, opportunity, circular economy, and iron. the findings underscore the importance of these areas in addressing environmental challenges and advancing green technologies for a sustainable, low-carbon steel industry. the results can guide policymakers in promoting green technologies, fostering innovations, and driving the transition towards a more sustainable steel production process.
