Impact investment that produces demonstrable environmental outcomes in addition to financial returns.
We are building hydrofoil vessels powered by electric and hydrogen propulsion. The only technology combination that delivers zero emissions at useful speeds and ranges for passenger transport.
International regulations are tightening. Operators need zero-emission solutions that don’t sacrifice speed or capacity. ZESST delivers both.
Regulation is closing the window.
MARPOL, ECA zones, EU Green Deal – every new regulation closes the window for diesel and opens it for clean propulsion. Operators who postpone the transition face rising costs and shrinking options.
Impact and returns – aligned.
Each PAX 100 in operation avoids 1,500+ tonnes of CO₂ per year. The programme aligns with IMO 2030/2040 targets and UNEP FI sustainable blue economy principles.
15+ years of aerospace-grade system engineering from Almatech (EPFL). Hydroptère speed record legacy. Swiss precision applied to maritime.
IMO mandates, EU Green Deal, local combustion bans on inland waterways. Every regulation closes the window for diesel — and opens it for ZESST.
Up to 20% lower total cost of ownership than a comparable diesel fast ferry, driven by reduced fuel, maintenance, and carbon compliance costs over the vessel’s service life.
Precursor for private owners, PAX 100 for commercial operators – two distinct revenue streams built on a shared engineering and supply-chain foundation.
Signed LOIs and business agreements with key operators and partners across Europe, Japan and the USA. Demand is validated, not hypothetical.
What we don’t claim.
What we commit to.
Two vessels, each engineered for one specific market
A pipeline of signed letters of intent with qualified operator
15+ years of aerospace system engineering heritage
A clear product roadmap with engineering milestones
We will not decarbonise the entire maritime industry
We don’t build for cargo or long-haul shipping
We aren’t the cheapest option, we aim to be the most reliable
We don’t publish specs on vessels we haven’t verified
