From the engine to H2 Mobility as a Service
Whether you choose to buy or lease: We can truly speak of a paradigm shift when we convert existing diesel engines into hydrogen engines in the most effective way. To make the transition to this new technology as simple, predictable, and risk-free as possible for our customers, KEYOU offers—when needed—a comprehensive, worry-free mobility solution. This includes not only the vehicle itself but also full-coverage insurance and a complete service and maintenance package.
H2 Vehicle
Our tractor unit based on the Mercedes-Benz Actros is classified as "Zero Emission" according to EU standards and is therefore toll-exempt. The vehicle is based on our KEYOU-inside technology, which stands for emission-free operation, high driving comfort, and maximum performance.
Service & Maintenance
No worries! We take care of the service for your H2 vehicle. Together with our partner network, we offer professional service as well as maintenance and repairs.
Insurance
With us, you get everything from a single source, including tailored third-party liability and comprehensive insurance, if desired. We work with renowned insurance companies that offer tailored conditions for our products.
Hydrogen
Vehicle and fuel go hand in hand. That's why you can also source your hydrogen through our local partners and benefit from attractive hydrogen prices.

The heart of KEYOU-inside: the hydrogen engine
As technology leaders, we at KEYOU recognize the value of reliable and powerful combustion engines. However, the disadvantages of diesel and gasoline engines are clear: they emit pollutants and cause environmental damage. KEYOU has developed a simple solution to this problem.
Our vehicles on the road
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 engine and just upgrading the core sub-systems necessary for an optimal hydrogen combustion operation. Around 80 % of the engine remains unchanged.
Drive up to 650 km without thinking about refueling
A "second life" for
existing vehicles
With our hydrogen expertise, our technology and our conversion know-how, we can solve the major challenges in the commercial vehicle sector and provide a cost-effective, CO2-free mobility solution - especially for existing vehicles. Our entry-level fleet consists of converted 18t trucks, which are being delivered to the first pioneering customers since early 2025.

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.”
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."
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."
Prof. Dr. Dirk Engelhardt
Vorstandssprecher BGL e.V.
