Smart. Simple. Sustainable.
Fleet operators face enormous challenges. Economic success alone is no longer enough today. You also have to do justice to the climate. That's why KEYOU relies on H2 Mobility as a Service renting out converted CO2-free vehicles with hydrogen engines - without risk but including fuel, service, and insurance.
Zero emission, maximum performance - our 18 ton truck
The base of our hydrogen conversion technology
We developed a proprietary low-temperature lean combustion concept that results in obtaining the highest performance with the lowest emissions.
The engine control system optimizes the management of the injection, air-charging, and ignition sub-systems, which have all been tailored for H2 burn. Some key mechanical components were improved for high durability.
A smart engine operating strategy with the selected setup takes advantage of the H2-fuel properties allowing: high power densities(27 kW/L), high low-end torque (90% of maximum torque at 900 rpm), and high brake efficiency (peak of 44.5%).
H2 combustion emits water vapor. Traces of CO2 originating from the lubricating oil are close to zero, as are NOx emissions due to the low combustion temperature achieved.
Build on top of a mature diesel engine base platform, KEYOU’s H2-Engine offers the same high reliability and durability as Diesel engines. Due to the low modification effort and the fast integration of new components, the extra cost to pay is low.
How an ordinary diesel...
...becomes a zero emission vehicle.
Hydrogen mobility without risk with pay-per-use
You do not have any experience with hydrogen? And want state-of-the-art technology without risk? While driving CO2-free and keeping an eye on your TCO? No problem, because we have developed an attractive "Pay-Per-Use" model for fleet operators. Unlike the usual purchase or leasing business, we rent out the converted trucks and charge a flat rate per kilometer ("pay-per-use") based on the annual mileage. This includes vehicle rental, maintenance and service, insurance, and even hydrogen. Our team, in partnership with trusted partners, will carry out maintenance and service for your vehicle.

Our engine & vehicle projects
Over the last few years, KEYOU has worked on several funded projects. From the EU-funded "H2Engine project" for the 18-ton truck to the "BayVFP bus project" funded by the Bavarian Ministry of Economic Affairs to the "WaVe Unimog project" as well as the "HyCET project" for the development of a 40-ton truck with hydrogen engine.
"HyCET" - Development of a 13-liter H2 engine
"BayVFP" - Development of 12-meter city bus
A special feature of this vehicle is that the hydrogen engine is operated here as a mild hybrid variant and thus meets the requirements that a transport company places on a city bus to a particular extent.
EIC "H2Engine" - Development of a 18-ton truck
In April 2023, our 18-ton truck received road approval from TÜV Süd and is now the first of its kind to be allowed to drive on public roads.
WaVe - Medium-duty H2 engine development
The next big thing
From 2025, we will offer the conversion of 40-ton trucks with a 13-liter KEYOU-inside hydrogen engine. Are you interested? Contact us today!
