The NoGAPS project assembled Nordic shipping and energy players to develop the M/S NoGAPS, a first-of-a-kind ammonia-powered gas carrier, and this final report documents what commercialising it actually required: design trade-offs, propulsion architecture, and financing strategies for a vessel type the market had never seen. The core challenge is identical to the one facing CO₂ shipping and every other alternative-fuel pioneer; zero-emission vessels cannot be made economic in isolation when the bunkering networks, fuel pricing frameworks, and regulatory infrastructure that would justify their unit costs have not yet been built.
