For 20 years, we at the LEC have been intensively researching in the field of sustainable large engine technology. The approval of the COMET K1 application LEC GETS – Green Energy and Transport Systems for the next 8 years or the award of the HyMethShip concept for green shipping with the Energy Globe Styria Award exemplify our pioneering role. However, all forward-looking developments at the LEC are the result of successful collaboration.
