Lightweight, high-performance propulsion for cleaner vessels

HyFlux is applying its cryogenic cooling and superconducting motor technology to hydrogen-electric maritime propulsion, progressing from system modelling towards vessel integration and demonstration.

The maritime challenge

Maritime operators need practical solutions that can reduce emissions while meeting demanding requirements for power, efficiency, reliability, weight and onboard space.
Hydrogen-electric propulsion offers significant potential, but successful deployment requires the fuel, cooling, electrical and propulsion systems to work together as part of the vessel's overall energy architecture.

Designed around the vessel

Our maritime approach considers the complete propulsion environment, including:
• Vessel power requirements and operating profile
• Hydrogen storage and fuel-cell integration
• Cryogenic cooling and thermal management
• Superconducting motors and electric drives
• System weight, footprint and efficiency
• Vessel integration, safety and regulatory approval
This system-level approach allows the propulsion and cooling architecture to be tailored to the vessel's duty cycle, available space, route and operational requirements.

Building a pathway to vessel demonstration.

Building on Maritime Experience

Through the UK Department for Transport's Transport Research and Innovation Grant programme, HyFlux completed system modelling and optimisation for a hydrogen-powered Ro-Pax ferry use case.

This work established an important foundation for applying HyFlux's technology within the maritime sector and progressing towards vessel integration and future commercial deployment.

Building Maritime Momentum

HyFlux is building a growing network across the UK maritime ecosystem, with active engagement involving vessel operators, ports, marine integration specialists, hydrogen and fuel-cell suppliers, research and testing facilities, and regulatory and certification stakeholders.

Combined with our completed maritime system-modelling work, these discussions are helping us define a credible pathway towards vessel integration and demonstration. We are now developing the right consortium and seeking a suitable vessel application for the next phase.

Towards Vessel Demonstration

HyFlux is developing a collaborative pathway to demonstrate its hydrogen-electric propulsion technology aboard a suitable vessel.

The proposed approach will consider the complete deployment pathway from fuel supply and bunkering through to onboard storage, power generation, cryogenic cooling, propulsion integration, vessel operation and regulatory approval.

Working with the right vessel owner and project partners from an early stage will allow safety, technical, commercial and operational requirements to be addressed together.
