Revolutionizing carbon-free maritime transport

Conceptualized and produced by Almatech Space and Naval Engineering, ZESST is building a fleet of hydrogen-powered boats that are silent and ecologically-friendly by only emitting water vapor. Thanks to their hydrofoils, the ships fly above the water offering unparalleled comfort to the passengers aboard the shuttle whilst consuming 85% less energy. This has the added advantage of being much less disturbing the maritime ecosytems they operate in.

The mission of ZESST is to offer an accessible and modern alternative to more conventional forms of water transport. The expertise acquired in the aerospace and naval industries allows ZESST to put state-of-the-art technologies to work towards environmentally-friendly boats. Founded in Switzerland at EPFL, ZESST combines innovation and Swiss quality to guarantee security, well-being and efficency.

zero-emission fuel cell

Green hydrogen and fuel cells power highly efficient electric motors. Only water vapor is released.


Wave reduction

The combined use of hydrofoils and an optimized hull design minimizes wave generation, protecting the environment and people from the impact of waves.

Exceptional cruising experience with ZESST vessels icon blue

fast and comfortable

No more seasickness! Thanks to hydrofoil technology, ZESST hovers above the waves making the boat's movements extremely smooth.

Become a Sponsor

By becoming a sponsor in Zesst, you join the team of pioneer aerospace engineers that turn visionary ideas into reality. Our vision is to build boats that provide unmatched “fly on water” experience while being powered only by renewable energies (hydro, wind and solar). Climate change requires real actions. The ZESST maritime craft are addressing a huge market opportunity for zero emission water transport.


Sponsors will not only be supporting us to achieve our goal but benefiting from the following opportunities.

Innovation and Sustainability

Associate your brand with innovative and sustainable solutions that shapes our future. Have insight on the ZESST development and performances.

Japanese Market

Gain exposure to the Japanese market. Due the rapid acceptation of hydrogen power transport in Japan, Zesst is already highly active.

Brand Exposure

Zesst Precursor is present at many international events, culminating with live showcase navigating at the World Expo 2025 in Osaka (est. 28 million visitors).


ZESST's revolutionary design saves 85% of energy. Genetic optimization algorithms are used to achieve this exceptional performance.

ZESST hydrogen boats performance icon


Established space technologies and extremely solid ultralightweight materials allow ZESST to be piloted at a cruising speed of 50km/h.

Hydrogen powered sustainable boats icon


Hydrogen is the fuel used in the ZESST motor. It is combined with oxygen from the air to produce energy and water vapor. The hydrogen is extracted from water using green energy. 

Our vision of maritime transport

Achieving zero-emissions water transport

Over 40% of the world’s population lives less than 40 kilometers away from the shoreline. The increase in economic activity in coastal regions is putting unprecedented pressure on our ecosystem. As the climate experts from GIEC stated: the time for decarbonization is now.

Our vision: Achieving net-zero emissions for maritime mobility.

Our mission is to build and deploy industry-leading, zero-emission, hydrogen-powered water craft that can help bring coastal societies closer to one another.

Our team's extensive experience and track record in the space industry sets us apart from conventional offerings in the market.

Total investment and operating costs are minimized through the optimization of resources and the smart integration of different technologies on board ZESST boats.

The introduction of each ZESST boat results in a reduction of more than 1'500 tons of CO2 per year per ship.

ZESST complies with national and international (MARPOL, ECA) environmental protection regulations and is a safe and sustainable investment for the present and future requirements of the 21st century. ZESST is building boat that follow the principles of sustainable blue economy financing (UNEP FI)
