Green hydrogen, derived from renewable sources like wind, solar, and hydropower, is gaining prominence globally as a carbon-free alternative to traditional fossil fuel-based hydrogen production. Its environmental benefits and versatility make it vital for sectors like transportation, industry, and power generation. Countries such as Germany, Japan, and Australia have embraced green hydrogen, recognizing its potential for economic growth and competitiveness. Vietnam, facing challenges of energy security and economic resilience, sees green hydrogen as a promising clean energy solution. The country aims to produce significant amounts of green hydrogen by 2030, aligning with its vision for a sustainable energy future. By following the lead of states like Kerala in India and Chile in South America, Vietnam can leverage green hydrogen for economic growth and environmental sustainability. Investing in green hydrogen can enhance energy security, reduce reliance on fossil fuel imports, cut costs, drive innovation, and boost global market competitiveness. With the right support policies, Vietnam can pave the way for a green hydrogen future, securing a position as a key player in the sustainable energy landscape.
