Abstract
Green hydrogen is increasingly recognized as a pivotal energy carrier in the global transition toward low-carbon energy systems. Beyond its established applications in industry and transportation, the development of green hydrogen could accelerate its integration into the power generation sector, thus enabling a more sustainable deployment of renewable energy sources. Vietnam, endowed with abundant renewable energy potential—particularly solar and wind—has a strong foundation for green hydrogen. This emerging energy source holds significant potential to support the strategic objectives in recent national energy policies, aligning with the country’s socio-economic development. However, despite this promise, the integration of green hydrogen into Vietnam’s energy system remains limited. This paper provides a critical review of the current landscape of green hydrogen in Vietnam, examining both the opportunities and challenges associated with its production and deployment. Special attention is given to regulatory frameworks, infrastructure readiness, and economic viability. Additionally, the study also explores the potential of green hydrogen in enhancing energy security within the context of the national energy transition.
