We decarbonize your fleet
With our pioneer vehicles, we are demonstrating that hydrogen engine technology also works in real life and is a cost-effective and robust alternative to battery electric or fuel cell vehicles. And you can be a "first mover" experiencing the commercial vehicles of the future.
As always. But green.
Our new 18-ton truck with H2 engine & KEYOU-inside
With our "P8" pioneer programm decarbonize your fleet, achieving another milestone. Proving that our technology is not only zero-emission but ready for the roads. Eight pioneer customers will have the chance to test their own 18-ton truck powered by a KEYOU-inside hydrogen engine under real-world conditions.
We create a full Hydrogen Mobility as a Service solution for your fleet
Past hydrogen engines have been clean but delivered low performance and involved complex adaptation work. KEYOU changes the paradigm by transforming existing diesel engines into hydrogen engines in the most effective way, by smartly utilizing the same base components and just upgrading the core sub-systems necessary for an optimal hydrogen combustion operation.View our solutions
…combines hydrogen as a sustainable fuel with the proven and economical combustion engine technology to create a quantum leap in drivetrain development.
…a complete retrofit solution, which includes an H2 tank system and the conversion of the engine, offers a diesel-equivalent cost structure, billed in a „pay-per-use“ model (€/km).
Service and Maintenance
…with our H2 Mobility as a Service model, we offer customers a fully comprehensive hydrogen mobility solution – including all necessary service and maintenance.
From the engine to H2 Mobility as a Service
The heart of KEYOU-inside: the hydrogen engine
Coming from engineering services, we know that reliable and powerful combustion engines are an indispensable part of everyday life. But older diesel and gasoline engines pollute the environment with high emissions. KEYOU has developed a simple solution to this problem.

Drive up to 600 km without thinking about refueling
A "second life" for
With our hydrogen expertise, technology and conversion know-how, we can solve the major challenges facing the commercial vehicle sector and offer a cost-effective mobility solution without CO2 emissions - especially for existing vehicles. Our entry fleet consists of eight converted 18 t trucks, which will be delivered to the first pioneer customers at the end of 2023.
Founders & management
Experienced managers, each with different expertise, characterize KEYOU's management. They have known each other for a long time and share a common vision: Thomas Korn, Markus Schneider, and Alvaro Sousa are three engineers with over 20 years of experience each in research and development of alternative drives. Together, the KEYOU management is pursuing a common goal: affordable and clean mobility based on the sustainable and energy-rich fuel of the future - hydrogen.
We are a team of engineers, climate activists, technicians, business experts, and engine enthusiasts. We all pool our talents and expertise in the high-tech company KEYOU to develop hydrogen-based, CO2-free mobility solutions that are pragmatic, efficient, and environmentally friendly.
What others say about us
We can tell you a lot. But we thought we'd let others have their say instead, who also have something to say about KEYOU and hydrogen.
