Hyperloop technology and test facility

Hardt Hyperloop was founded in 2017 by a group of students from Delft University of Technology. It develops technology for fast, energy-efficient transport of passengers and freight, and has spent years on the core systems: magnetic levitation, propulsion and high-speed lane switching. The company designs autonomous vehicles capable of speeds of up to 700 kmph. eu-startups.comEU-Startupseu-startups.comOpen source ↗

Its product portfolio includes hybrid electromagnet traction units, sensor systems for real-time air-gap control, silicon carbide-based magnet drivers and laminated steel track sets. It also offers application engineering and route development. Earlier, the company worked with Schiphol Airport on a hyperloop route plan. eu-startups.comEU-Startupseu-startups.comOpen source ↗
