Vietnam’s hydrogen energy development strategy to 2030 and vision to 2050 (Hydrogen Energy Strategy) was approved by the Prime Minister in Decision No. 165/QD-TTg dated February 7, 2024. Hydrogen is the energy source of the future but also a new investment field for Vietnam. Developing the energy source will therefore face many difficulties and challenges. Some analysts believe that investors face issues with procedures and completing documents to build projects, while others believe that green hydrogen is a new energy source produced from renewable energy, so the investment cost will be significant and the selling price quite high compared to other renewables. Vietnam also currently lacks a technology platform to produce green hydrogen. From now to 2030, it is necessary to research the step of mixing fuels such as coal with ammonia and liquefied petroleum gas with hydrogen for effective deployment in the 2030-2050 period.
