Good to Sea
Designers of green maritime transport
A clean and viable solution for forward-looking ship owners worldwide.
On-going developments in hydrogen technology and infrastructure are creating commercially attractive options for passenger and cargo transport industries worldwide.
By designing catamarans equipped with electro-hydrogen propulsion, our team of engineers is re-engineering the propulsion system and the vessel architecture to reduce mass, optimise energy efficiency and allow this new energy vector to be integrated on board in complete safety.
Green Navy will offer new, adaptable, efficient and environmentally friendly solutions for operators to buy or lease – fuelled by public awareness and demand.
Modular superstructure to suit your needs
What differentiates Green Navy is our flexibility.
The Green Navy electro-hydrogen solution is uniquely adaptable to every operator’s budget. Any PAX, CARGO or PAX/CARGO layout can be built with a carefully calculated number of batteries and hydrogen bottles depending on the needs of the end user optimising weight/autonomy and charge cycles.
Green Navy vessels will also offer an extremely advantageous ratio in terms of energy consumed, weight of vessel and distance travelled.

Our ships will be powered by electric motors powered by NMC Lithium-ion batteries. They will carry hydrogen stored at 350 bars as a Range-Extender. The fuel cells will combine this carbon-free and renewable energy source with the oxygen present in the air to produce electricity and recharge the battery fleet. During their operation, PEM fuel cells will produce water vapor for their only emission.
Electro-hydrogen propulsion is therefore cleaner than any other motorised propulsion using fossil fuels because it does not produce greenhouse gas emissions or air pollutants. It is silent, odourless and vibration-free, and it offers superior efficiency. These major benefits make Green Navy’s electro-hydrogen propulsion better for the environment and closer to the global goal of clean and sustainable shipping.
The Green Navy solution goes much further.
Green Navy will be the first company in Europe to implement this technology on board in the context of passengers and goods which makes our catamaran unique in the marketplace.
The vessel will be supplied with green hydrogen to ensure a complete carbon-free chain. In addition, we are developing an innovative transmission system with an optimised reduction system that develops greater torque at reduced propeller rotation speed. This will improve efficiency and reduce the energy consumption of our vessels.
Our commitment to efficiency has seen us work closely with G-Sea Design on the ultimate precision of structural calculations. This has resulted in a lightweight catamaran prototype with exceptional strength and rigidity – tested in all weather conditions and in passenger/cargo/ and combined configurations.
We are designing and producing in France a clean technological vessel that is carbon-free with low energy consumption, offers full marine capacity, and is available at short notice.
Our team of engineers has optimised the propulsion system and the architecture of the vessel to reduce its mass and provide an adaptable, efficient and environmentally-friendly solution.
Our boats are powered with Green Hydrogen derived from the electrolysis of water using renewable energy.
GH2 – zero emissions during production and use.
Impressive performance thanks to an intelligent propulsion management system:
- Range of 300km at 8.3 knots, approximately 36 sailing hours.
- Range of 244km at 9.3 knots, approximately 25 sailing hours.
- Maximum speed of 12 knots, or 14 knots on demand.

Regardless of your desired configuration, our boats will be available for medium & long-term lease, and outright sale.
Our growing team, which already comprises 12+ dedicated, experienced and enthusiastic individuals, is available to discuss your project and build a solution to meet your needs.
Co-founder of Green Navy, Guy is a naval architect and maritime expert with 50 years of experience. He has demonstrated his commitment to carbon-free mobility by working on the design and improvement of precursor boats in this sector – in particular, the Energy Observer and the Planet Solar. We owe to him the design of the Green Navy prototype boat.
Founder of Green Navy (2019), Atila Perez is committed to reducing the environmental footprint in the maritime transport sector. Born in Mexico, he has lived in France since 1999. After an early career in the catering sector, Atila is now at the helm of three Carrefour retail shops.
Partner of Green Navy, Grégoire is also the Chairman and Founder of VALLAIR, a Franco-Luxembourgish group specialising in the maintenance of airliners (MRO), as well as in the recycling activities of mature aircraft, engines and aeronautical components. With a cumulative experience of 30 years in aviation, notably at Airbus and Air France, Grégoire has developed a pioneering aircraft disassembly and cargo conversion business in Europe.
Our newly appointed Chief Executive Officer. Cardi is a maritime expert with cross-functional experience and a background in electro-technical studies, he joins the organisation from UNI Bateaux in Ajaccio, Corsica, where he was responsible for all sales and charter operations of motor yachts, catamarans, trawlers and NUC passenger boats.
