New hydrogen viability collaboration project

A collaboration between Pulling-e and the University of Cambridge will see the development of a zero-emission catamaran racer designed to showcase the viability of hydrogen as a cleaner fuel source for the maritime industry.

The catamaran – to be shown at the Monaco Energy Boat Challenge in 2024 – will incorporate a propulsion system designed by Pulling-e which will facilitate a hybrid power source system, feeding a specifically designed electric motor, directly driving a pulling type propeller within the underwater pod unit.

The design has been developed for efficient propeller operation and gearless power transfer from the electric motor directly to the propeller.

Pushing the boundaries

“Creating a holistic and tailor-made design for the team has been exciting, pushing the boundaries of innovation to create something unique, purpose-built and engineered to meet the demands of this challenge,” said Heikki Bergman, CEO and design manager of Pulling-e. “This is about pioneering new frontiers in sustainable maritime technology, and we are eagerly anticipating Monaco to showcase the results.”

Each Pulling-e propulsion unit is custom-tailored to its specific purpose, with propeller type and diameter designed to maximise efficiency.

In the case of this project, the additional constraint of a restrictive weight limit has been at the core of the design process with lighter materials chosen rather than traditional options.

Testing and validation

Prior to the challenge, testing and validation will take place to ensure that the boat is ready.

The team at Pulling-e will then verify the component delivery through full-scale testing in their workshop.

The Monaco Energy Boat Challenge combines innovation and sustainability, with participants encouraged to explore new technologies, innovative materials and alternative propulsion systems.

More than 40 teams from around the world will compete against each other in terms of speed, agility and endurance.
