Vietnam’s rapid industrialization has led to a sharp increase in energy demand and greenhouse gas emissions, posing critical challenges for achieving its Net Zero target by 2050. This study develops a techno-economic and system-level framework to evaluate the integration of carbon-neutral liquefied natural gas and hydrogen in Vietnam’s energy transition. A scenario-based model is constructed to quantify emission reduction potential, system costs, and sectoral decarbonization pathways. Results indicate that integrating carbon capture, utilization, and storage into LNG-based power systems can reduce emission intensity from ~450 gCO₂/kWh to below 100 gCO₂/kWh. Hydrogen deployment across industry, transport, and power sectors could contribute up to 280 MtCO₂ reduction by 2050. Levelized cost analysis shows that CN-LNG remains cost-competitive in the near term (70–110 USD/MWh), while green hydrogen becomes economically viable post-2040 under declining renewable costs. Vietnam’s estimated CO₂ storage capacity (~11.8 Gt) enables large-scale CCUS deployment. The study highlights that a hybrid pathway combining CN-LNG and hydrogen offers a robust and flexible strategy for balancing energy security and deep decarbonization.
