Holthausen

A hydrogen fuel cell-powered street sweeper developed by Holthausen and Visedo, now operating in the town of Hoogezand in the Netherlands.

A demonstration project by the Holthausen Group that retrofitted a Tesla Model S with a hydrogen fuel cell system in addition to its existing battery. The modified vehicle, called the Hesla, combines both power sources to achieve a range exceeding 620 miles.

A modified Tesla Model S equipped with both a hydrogen fuel cell system and the original Tesla battery. The vehicle achieves a range exceeding 620 miles and serves as a proof of concept for hybrid fuel cell-battery vehicles.

A technology that combines hydrogen and oxygen in a clean, electrochemical process to generate power, releasing only water vapor as a byproduct.

Vehicles powered solely by electricity stored in batteries, representing a significant advancement from earlier electric car models.
