The article discusses the transformative potential of green hydrogen in Vietnam's energy landscape. Dr. Majo George, an RMIT senior lecturer, highlights green hydrogen as a carbon-free alternative generated through electrolysis powered by renewable energy sources. Green hydrogen is distinguished from grey hydrogen by being completely clean, contributing significantly to the global shift towards sustainable energy. The technology's versatility across sectors like transportation, industry, and power generation makes it essential for nations striving to achieve net-zero emissions targets. Countries such as Germany, Japan, and Australia have successfully integrated green hydrogen, recognizing its economic potential for boosting growth and competitiveness. Vietnam, in its National Hydrogen Development Strategy, aims to produce 100,000-500,000 tons of hydrogen annually by 2030, underlining the country's commitment to embracing green hydrogen. The article emphasizes five key reasons for Vietnam to adopt green hydrogen, including energy security, economic advantages, environmental responsibility, industrial innovation, and global market competitiveness. By investing in green hydrogen, Vietnam can reduce its reliance on fossil fuel imports, cut costs, fulfill environmental commitments, drive innovation, create jobs, and enhance its position in the global sustainable energy market.
