Project Summary
This project delivers a new 3kV solid-state circuit breaker prototype with fault clearance 100 times faster than traditional electromechanical breakers, supporting the electrification of large vessels through high-voltage Direct Current (DC) power systems. The proposed technology uses wide bandgap semiconductors and an innovative detection and decision algorithm to address the limitation of slow response of electromechanical breakers. This breakthrough will improve safety, minimise equipment damage, and set a new standard for reliability of DC networks for low- and zero-emission vessels. This innovation enables a more efficient integration on board of renewable energy sources, energy storage, and low carbon fuels that necessarily require high-voltages when the powers involved are above 10MW. This project aligns with the UK’s net-zero goals by facilitating the adoption of efficient DC power systems, reducing power losses, infrastructure costs, and greenhouse gas emissions. The innovation has the potential for adoption beyond maritime for other transport sectors requiring high power for electrification, such as rail and aerospace. The adoption of low- and zero-emission solutions is critical for the wellbeing of end-users and society, as it would reduce the negative effects on health related to transport pollution.
