From the engine to H2 Mobility as a Service

We can certainly call it a paradigm shift: converting existing diesel engines into hydrogen engines in the most efficient way. To ensure a smooth, predictable, and risk-free transition to the new technology for our customers, KEYOU offers an all-inclusive mobility solution. This solution includes full insurance coverage and a comprehensive service and maintenance package alongside the vehicle. With our pay-per-use model, fleet operators rent the vehicle and pay a monthly flat rate per kilometer based on their annual mileage.

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.

Explore our technology

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.

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 2024.

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."

Prof. Dr. Dirk Engelhardt

Vorstandssprecher BGL e.V.
