About the company

Grafmarine is a UK-based clean technology company pioneering smart, renewable energy systems for the maritime sector.

Its flagship product, NanoDeck, is the world’s only modular photovoltaic (PV) energy platform engineered specifically for harsh marine environments. It transforms flat surfaces on vessels and port infrastructure into intelligent, self-contained energy systems, reducing fuel consumption, emissions, and operating costs while improving ESG performance.

NanoDeck is a walkable, plug-and-play energy solution that reduces vessel fuel consumption and emissions by up to 10%. It combines high-efficiency PV generation, onboard battery storage, and intelligent energy management in a solid-state system tailored to vessel-specific energy profiles to optimise performance and simplify maintenance.

Grafmarine’s technology aligns with global decarbonisation goals by offering scalable, retrofit-ready renewable solutions for commercial shipping, ports, and offshore operations. Backed by Innovate UK and EU funding, and trialled with major shipping operators, Grafmarine is leading the shift toward cleaner oceans through innovation, sustainability, and practical design. Its circular economy model and international patent portfolio position it as a key player in the future of marine energy transition.

Available via purchase or lease, NanoDeck lowers CapEx barriers and allows operators to future-proof assets through component upgrades without replacing the full system.
