Effective systems integration is a critical enabler of hydrogen adoption. This session presents a deployment-led view of integrated methanol-to-power solutions, combining onboard hydrogen generation and fuel cell technologies. Drawing on recent yacht retrofit projects and multi-megawatt commercial orders, e1 Marine and PowerCell will explore how fully integrated systems are enabling fuel cell adoption for auxiliary and propulsion power without reliance on hydrogen bunkering. The discussion will examine how this approach reduces integration complexity for shipyards, supports electrification strategies, and enables earlier deployment across vessel and port applications where infrastructure remains constrained.
