The OECD Sustainable Infrastructure Programme in Asia (SIPA) partnered with key Mongolian organizations to develop a strategic report on renewable hydrogen. Mongolia aims to shift from a coal-powered economy to a low-carbon one, with renewable hydrogen playing a pivotal role. The country faces challenges such as a fledgling domestic market, investment uncertainties, water scarcity, and technological gaps. To address these, the report suggests attracting investments through incentives, aligning policies with climate goals, and developing pilot projects in collaboration with international partners. Water sustainability is crucial, with proposals for using saline aquifers and integrating hydrogen water-use policies into broader climate resilience strategies. Mongolia aims to become a global hydrogen hub by cooperating internationally, securing export agreements, and ensuring hydrogen quality meets global standards. Early projects like the solar-based hydrogen project and wind energy initiatives offer insights for large-scale production. Success depends on overcoming regulatory hurdles, ensuring water sustainability, and mitigating investment risks. Mongolia's transition to a renewable hydrogen economy signifies economic diversification and growth, contingent on effective policymaking and strategic investments.
