   Lao PDR’s abundant hydropower resources offer significant potential for green hydrogen and ammonia production. This study evaluates the feasibility of producing green ammonia domestically as an alternative to traditional electricity exports. Using an integrated energy systems modelling approach that combines power system optimisation with hydrogen production and ammonia synthesis pathways, we assess the trade-offs between exporting electricity and converting surplus generation to green ammonia. Our findings indicate that leveraging existing and planned hydropower capacity, Lao PDR could produce competitively priced green ammonia, offering a diversified revenue stream and reducing dependence on volatile electricity export markets. We discuss the infrastructure requirements, cost implications, and policy considerations for this transition.
