Graf Marine

Powering the future of sustainable shipping

A viable GHG-free maritime energy platform.

Graf Marine

At Grafmarine, our mission is to provide smart, safe and sustainable energy generation and storage that support the decarbonisation of the maritime industry. As specialists in intelligent power management, we have developed NanoDeck, a future-proof energy deck that reduces fuel consumption, carbon emissions and operating costs. NanoDeck is projected to generate average fuel savings of 10% using current technology; this is expected to increase significantly as panels become more efficient in the coming years.

Using advanced renewable technology, NanoDeck transforms any flat surface into a platform for generating and storing energy. Designed to reduce costs and accelerate the decarbonisation of new and retrofitted vessels, this patented modular AI solar energy system provides a highly durable and integrated power management solution. Its plug-and-play, solid-state system can be optimised to meet individual vessel energy usage profiles.

The only known energy system of its kind, NanoDeck can be deployed in all maritime environments and compliments all new renewable systems such as wind, air lubrication and all maritime fuels, including hydrogen, LNG Ammonia etc. Safe and scalable, this advanced system reduces fuel consumption and operating costs while actively contributing to the global fleet’s transition to net zero.

A global demand for decarbonisation

In 2015, the Paris Agreement established a global framework to limit global warming to 1.5°C1. In an effort to reduce carbon emissions from ships engaged in global trade, the International Maritime Organisation (IMO) has adopted mandatory energy efficiency regulations. From 2026, non-compliant fossil fuel-powered ships, which account for more than 75,000 existing vessels, will be phased out. These measures aim to reduce emissions by 40% by 2030 and by 70% by 2050 compared to 2008 levels.

Grafmarine is committed to supporting a sustainable ocean economy and has united behind the IMO’s mission to decarbonise the shipping sector by 2050. The zero-emission NanoDeck provides a robust and practical clean energy source with intelligent integration and storage benefits to support the world’s shipping fleet in meeting its energy transition objectives.

Seaport Sustainability

In addition to helping shipping fleets decarbonise and meet future regulatory targets at sea, Nanodeck’s plug-and-play technology massively reduces operating costs in smart, low-carbon ports. Our zero-emission, scalable and sustainable power hub seamlessly integrates into future-fuel-ready seaports around the world, allowing ships to turn off their engines and rely on clean, renewable power.
