Marine & Maritime grants
Clean maritime, offshore and marine technology funding for UK innovators
Maritime innovation is a growing UK priority, from zero-emission vessels and port infrastructure to offshore renewables and marine autonomy. Innovate UK, DfT and the Clean Maritime Demonstration Competition back projects that can demonstrate real-world emissions reduction, safety improvement or operational efficiency in a harsh, regulated environment.
