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.

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.

Engine Conversion

…combines hydrogen as a sustainable fuel with the proven and economical combustion engine technology to create a quantum leap in drivetrain development.

Vehicle Conversion

…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

We can certainly speak of a paradigm shift when we convert existing diesel engines into hydrogen engines in the most effective way. With the help of our KEYOU-inside system, we convert existing diesel commercial vehicles into CO2-free hydrogen vehicles. This enables our customers to drive emission-free, efficiently, and economically - without compromising on performance, capacity, or range.

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.

The story behind KEYOU - we have the KEY for YOU

It all started in a basement in Porto with a bold idea: transforming the global transportation sector through the power of hydrogen. The three KEYOU founders have been working on this vision for most of their professional lives.

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.

Meet KEYOU

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.

"Hydrogen is the fuel that powers the universe. I strongly believe that hydrogen-based technologies are essential alternatives to meet the world's complex mobility needs.”

Ulrich Bez
Advisory Board Member
“Without internal combustion engines, it will still not be possible to solve all transportation tasks and drive working machines in construction and agriculture in the future.”
Testimonial image
Rudolf Ellensohn
Advisory Board Member
"Electric trucks are out of the question for our purposes. On the test track, we were very positively surprised by the performance of the 18-ton truck, so we decided quite early on to order two vehicles."
Testimonial image
Markus Pumpf
Geschäftsführer, EP-Trans
"KEYOU's hydrogen engine drive technology for converting existing diesel fleets represents an important building block in the portfolio of alternative climate and environmentally friendly drives. The conversion of the existing fleet fundamentally enables an immediate contribution to the reduction of CO2 emissions in heavy-duty traffic."
