Our new 18-ton truck with a Hydrogen 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.

Become a pioneer

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.

01.

Conversion

We convert the engine and vehicle to H2 for you. Lowest possible investment for customers who want to use zero-emission hydrogen trucks and maintain their current business model.

02.

Hydrogen Fuel

Vehicle and fuel belong together. The customer also gets hydrogen from us. The short distance between the customer site and hydrogen production, and full utilization of filling stations. A business case for all.

03.

Service & Maintenance

Don't worry! We will take care of the service for your H2 vehicle! Together with our partner network, we offer professional H2 service and repair.

04.

Insurance

From us, you get everything from a single source, including the best liability and comprehensive insurance. Here we fall back on well-known insurance companies that can offer special conditions.

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.

Our vehicles on the road - tests in full swing

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.

Drive up to 600 km without thinking about refueling

A "second life" for
existing vehicles

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.

The story behind KEYOU - we have the KEY for YOU

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."
