As part of its “Engineering Forum” lecture series, IG Metall Cologne/Leverkusen invited KEYOU as a speaker for the 6th of November. After announcement of the topic it became apparent prior to the event that a great deal of interested listeners can be expected. Fortunately, the DGB House was able to move the lecture to a larger hall. Cornelius Preil, responsible for Business Development at KEYOU, held a 45-minute lecture entitled “The Hydrogen Engine – Drive Technology On-Road and Off-Road”. This was followed by a lively discussion. At the end of the event all participants were satisfied – KEYOU says “Thank you” again!
