Harnessing Hydrogen to use for power is not without it's challenges. But it is now possible.
The primary propulsion system onboard is always the wind. When there is not enough wind (and we have somewhere to be) instead of a diesel engine to directly drive the propeller shaft, this is done by an electric motor. Advanced LiFePO4 batteries, bifacial solar PV modules and a wind turbine provide for the majority of loads when running. Diesel is currently used only if we need to recharge the battery. Under sail and managed well, there is generally no need to start the diesel generator.
If we do need use the generator, this is run at its optimum efficiency and for the shortest possible amount of time. Propelled by an electric motor improves the efficiency from 15% at best using a traditional drive train, improving to ~45% using an electric drive. We are able to run primarily from wind and solar, and even regen when sailing, but if we do use fossil fuel, every ml is optimised.
The objective is to go a step further and showcase a hydrogen fuel cell that will replace the diesel generator entirely. This is as we see it the only way to provide high density fuel on board sustainably. The technology is evolving quickly and though there is still a long way to go, showcasing how far we've come is key to further development which ultimately leads to mainstream use.
With so many pieces to this puzzle, we know that true sustainability means every aspect must be dealt with. It is not enough to say we are powered by green Hydrogen, what is the impact of the tools and equipment? The true environmental impact in use? What is the duty cycle? How are parts recycled? and actually, do we really need all the electrical power we think we do?
We aim to offer an entirely electric craft that offers a real world practical facility for education and continued research and development as well as an inspiration for anyone who visits. As the technology evolves so does the uptake, and with right investment in infrastructure to provide the clean H2 locally, the idea becomes viable for all sooner.
In collaboration with our supporters, the ongoing collection of data for both environmental and technical review are key to further advance a Hydrogen economy.
With the upmost standard of care in engineering and seamanship ensures the carbon footprint of our sailing boats is kept to an absolute minimum.
As we further develop our powertrain systems, and as like minded operators begin to take up the technology with us, locally produced “green” Hydrogen can be generated using renewable energy, driving down operating costs, raising awareness and significantly offsetting carbon dioxide emissions. This is not only for maritime, but on roads, on farms, in homes and in the workplace. We're helping to inspire a movement towards a Hydrogen economy, and the bigger the uptake, the sooner it becomes the norm. If you want to come onboard please send us a message.
