Transport & mobility

The start-up

ZPARQ is a tech startup that is challenging the limits of marine electric propulsion.

The need

There is a need for new and improved electric drivetrain technology for propeller-driven watercraft to meet the growing demand for fossil-free marine transportation. Currently, no cost-effective submerged electric motor system on the market can offer both high power and high efficiency.

The solution

Zparq vastly improves marine electric propulsion with a compact and scalable direct-drive system for propeller-driven watercraft which solves fundamental limitations of current market offerings. Technology is based on a novel motor design that specifically adapts to submersible applications. A patented passive cooling system allows the motor to be up to 10 times smaller in volume than motors with equal power.

The value proposition

  • Small volume  – minimal underwater drag.
  • Few parts – low production cost and fewer failure points.
  • High efficiency – longer range.
  • Submerged – low noise and compact.
