Who is KEYOU?

KEYOU is a successful high-tech company from the Clean Mobility sector that develops innovative hydrogen technologies, specific H2 components and combustion processes for engine and vehicle manufacturers, with the help of which conventional engines can be transformed cost-efficiently into emission-free hydrogen engines - without major modifications to the basic engine.The new "green" combustion engine with KEYOU-inside technology means zero emissions, efficiency and economy at the same time - without compromising on performance, capacity or range. Vehicles with corresponding engines are considered zero emission vehicles according to the current EU standard. The technology is engine- and manufacturer-independent, scalable and can be used both onroad and offroad. Currently, the focus is on commercial vehicle engines. "Sustainable Zero Emission" thus becomes reality with KEYOU.
