KEYOU starts strategic partnership with KST-Motorenversuch

Next growth step for Munich-based Clean Mobility start-up

KEYOU New hydrogen engine alliance: KEYOU starts strategic partnership with KST-Motorenversuch and establishes “H2 Development and Test Center” in Rhineland-Palatinate

München, 18. November 2020,

While the COVID 19 pandemic is causing considerable economic difficulties for companies in many places – especially in the automotive industry – KEYOU continues to grow successfully. After the Clean Mobility start-up recently relocated its corporate headquarters from rural Unterschleissheim to Munich, it is now establishing a new “H2 Development and Test Center” in Rhineland-Palatinate in the context of a strategic partnership with KST-Motorenversuch GmbH & Co. KG. For the Munich-based high-tech company, the partnership with the experienced test bench operator is another important milestone, especially after the recent funding and participation of the European Union in the company.
Rhineland-Palatinate is a strategically favorable location for the Munich-based hydrogen specialists. On the one hand due to the expertise of the new partner KST-Motorenversuch, on the other hand due to the support of politics. After all, Rhineland-Palatinate is considered one of the model states, when it comes to hydrogen. Only recently, Rhineland-Palatinate’s Minister of Economics and Deputy Prime Minister Dr. Volker Wissing announced at a press conference that, above all, the development of hydrogen engines for the commercial vehicle sector, which is strong in the state, is to be promoted. Prof. Dr. Gerhard Reiff, Chairman of the Board of Directors of KST, also shares the view of the Minister of Economic Affairs: “In my view, it makes more than sense to take the path to a CO2-neutral, green mobility future via the hydrogen engine, since we Europeans have an excellently functioning supply chain for combustion engines and series production for commercial vehicles can be realized in the short term.
The strategic partnership with KST, a company with a long tradition, offers KEYOU – in addition to the favorable political framework – the opportunity to meet the increasing number of customer inquiries from engine and vehicle manufacturers. The cooperation also offers both companies sufficient growth potential for the future. “The demand for hydrogen combustion engines has risen drastically in recent months, certainly also due to the increasing support from politicians. In the coming year, we even expect to double our number of projects. We are happy that with KST we now have a strong partner from the automotive industry on our side who builds and operates test benches for hydrogen engines and components for KEYOU. We are thus setting the course for future growth and at the same time can increase our test bench capacities already at short notice. We are convinced that both sides will benefit from this strategic cooperation in the long term,” says Thomas Korn, CEO and co-founder of KEYOU.
The “H2 Development and Test Center”, as the location in Bad Dürkheim is called, is the second pillar of the Clean Mobility Start-Up, in addition to the new offices in downtown Munich. While the majority of employees will remain at the headquarters in Munich, there is also a fixed number of KEYOU engineers in Bad Dürkheim who will be supported on site by experienced KST employees.
“We are very pleased to be able to offer KEYOU, the ‘hydrogen pioneer’, an innovative development and test platform on almost historic ground in automotive development history, and thus to be able to work together on the successful turnaround in mobility,” explains Prof. Dr. Gerhard Reiff, Chairman of the Management Board of KST-Motorenversuch GmbH & Co. KG.

About  KEYOU
KEYOU is a successful high-tech company operating in the field of clean mobility, which develops innovative hydrogen technologies, more specifically hydrogen components for engine and vehicle manufacturers. These technologies enable conventional engines to be transformed cost-effectively into emission-free hydrogen engines – without significant modifications to the base 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 hydrogen engines are considered zero-emission vehicles according to EU standards. The technology is engine and manufacturer-independent, scalable, and can be used for both on- and off-road but ultimately for all applications that use a combustion engine. The current focus is on commercial vehicle engines.

Proton Motor and KST-Motorenversuch cooperate in the H2 range

Puchheim near Munich, October 28, 2020 – National and regional alliances are highlighting the increasing significance of hydrogen as an alternative energy carrier to achieve climate targets and decarbonise our planet. For over 20 years technology pioneer “Proton Motor Fuel Cell GmbH“ ( has successfully dedicating itself to the development and production of hydrogen fuel cells for stationary and mobile applications. In the area of automotive applications, the commissioning of “E-Trucks Europe” to equip refuse collection vehicles with the HyRange© solution to increase range was announced this year. In order to expand sales activities, the cooperation with ”KST-Motorenversuch GmbH & Co. KG“ ( is now contractually agreed.

The collaboration between the engineers from Puchheim and Bad Dürkheim is essentially based on the joint establishment of test procedures and test facilities for the development of hydrogen fuel cell systems. KST contributes its more than 50 years of experience as a development service provider and test facility operator for the automotive industry. In the first step, a KST test bench will be specially converted for hydrogen operation, on which a Proton Motor system is tested as a pilot. The aim of the cooperation is to create a long-term partnership. Both sides have agreed to the continuous qualification of students for training within the fuel cell high-tech sector as a cross-generational task for the future.
