This Research investigates the potential of electrically heated methane pyrolysis for offshore hydrogen production as part of global grid decarbonisation strategies. Unlike steam methane reforming, methane pyrolysis produces hydrogen and solid carbon without emitting carbon dioxide. The study evaluates reactor designs in particular fluidised and molten metal configurations modelling their integration with offshore renewable energy sources such as wind power. Results show that methane pyrolysis has significantly lower energy demands and lifecycle emissions compared to conventional hydrogen production methods. Techno-economic analysis indicates hydrogen production costs ranging from $1.45 to $1.60 per kilogram under 80% renewable uptime conditions, emphasising its feasibility for remote and off-grid applications. The approach presents a scalable solution for cleaner hydrogen generation and supports the transition towards low-emission energy systems.
