This study examines the production, transport, and supply costs of key Power-to-X products for 2030, analyzing 39 globally distributed regions in 12 developing and emerging countries. It assesses renewable energy and Power-to-X production and supply cost potential through extensive country analyses, identifying promising regions and optimizing Power-to-X production pathways. The focus is on renewable electricity generation costs and the simulation-based optimization of Power-to-X chains for producing renewable hydrogen, ammonia, methanol, and jet fuel. Import scenarios consider long-distance transport of green energy carriers to Germany via ocean-going vessels or hydrogen pipelines, relying on dedicated renewables for 100% renewable hydrogen production.
