University College London
A group of eight 4 th year UCL Mechanical Engineering students, enthusiastic about marine engineering and renewable energy and its application in competitive contexts. We each chose to compete in the MCSEBC and began working on the project in September 2020. It was also the starting of our journey as friends. We decided to compete in the energy class competition because we want to encourage the use of clean energy in the marine industry with our project as one of the starting points. We aim to design and build a cockpit and a propulsion system using a hydrogen fuel cell and a Li-ion battery. We chose to participate in the energy class as innovating a boat with 100% clean energy was never done by our university and we took it as a challenge to prove that it was possible.
The propeller and drivetrain system consists of a podded drive propulsion system (with the motor and propeller both submerged). The control system maintains a steady power current to the motor from the hydrogen fuel cell and battery. A single central semi spade rudder with a NACA0012 profile will be used to manoeuvre for the Slalom race. Special innovation includes incorporating two hydrofoils at the bottom of the cockpit that reduces the power required by the boat from 10.1 kW to 2.7 kW. A 5m long catamaran powered entirely from a hydrogen fuel cell (5
kW) and lithium ion battery.
