Our primary propulsion system is the wind. When there is no wind (and have somewhere to be), instead of a diesel engine to directly drive the propeller shaft, this is done by an electric motor. The diesel is used if we need to recharge the battery. Advanced solar PV modules top up the battery to get in and out of harbour and provide for the majority of loads when running. Under sail and managed well, there is generally no need to start the diesel generator in local waters. The boats operate on electric, but we must keep the generator available to use just in case.
We aim to go a step further and showcase a hydrogen fuel cell to replace the diesel generator. Combined with an electric propulsion system, the fuel cell is an electrochemical cell which captures the electrical energy of a chemical reaction between hydrogen and oxygen, in a reverse electrolysis, and converts it into electrical current, releasing water as exhaust. This initiative removes all fossil fuel on board including diesel for propulsion and heating, LPG for cooking and petrol for the tender. Fuel cells are combined to form a 'stack', in order to provide the levels of power output required for practical use.
An entirely electric craft that offers a real world practical facility for education and continued research and development, and 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 commercially viable for all sooner.
Using Fuel Cells which power the highly successful Hydrogenesis ferry project in Bristol harbour, we are adapting the technology for use in the challenging waters of the Bristol Channel in our 34ft yacht. The Hydrogenesis, completed its 7th season of reliable operation in the Bristol Harbourside. The award winning boat has proven Auriga Energy’s fuel cell system works in all weather conditions from heat waves to freezing and damp conditions, and without fault since entering the water in 2012.
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 and our 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.
