RiAlAiR offers the first real Electric Boat solution for professional users in sectors untouched until now, such as fishing and passenger boats up to 50 gross tons. At the core of our business model is Aluminium-Air battery technology. By moving from fossil-based fuels to our electric solution, boat owners and operators will also obtain a cleaner, safer, lighter boat with longer range autonomy.
Our subscription service will offer owners and operators a combined total of capital repayment (including interest) plus operating daily costs which will be lower than the current daily costs faced by professional boat users, which means more money in their pockets at the end of every working day… and increasingly over time.
We can achieve this through positive and active collaboration with:
We do not need to neither own nor lease the boats our self as they are and remain owned by their current operators or leased by our partners.
At macro level, with the first marine solution of its kind, we create local jobs, clean up the air and water and reduce national trade deficit for those countries that currently import fuel for their fishing industry and we can enter profitable markets anywhere as our approach can be applied to millions of boats globally.
RiAlAiR Group is aiming to provide an effective, efficient and sustainable energy solution in the marine environment (fishing boats, water taxi, recreational boats), by exploiting the high capacity and lightness of Al-Air electrochemistry and then evolve it in the larger setting of ships and ferries.
RiAlAiR was born from the collaboration of a team of friends and colleagues aiming to change electric mobility for the better and create waves of positive impact. Our management team boasts well over 200 years of combined managerial, technical and entrepreneurial international experience across industries such as energy, renewables, telecommunications, oil and gas, construction, healthcare and information technology. Everyone in the management team is a seasoned professional and an expert leader in his or her field.
Aluminium–Air (Al–Air) batteries are primary cells, thus non-electrically rechargeable. The aluminium anode immersed in a water-based electrolyte is consumed by its reaction with atmospheric oxygen (the cathode). Aluminium–Air batteries produce electricity from the reaction of the oxygen in the air with the aluminium anode.
The good news is that not only it is possible to recharge mechanically the battery by replacing the exhaust anodes with new Aluminium anodes, but it is also possible to recycle the Aluminium Hydroxide, so that the cycle is 100% environmentally friendly and no emissions are released into water or air.
Al-Air batteries have one of the highest energy densities of all batteries because part of the reactants come from the air. Since Aluminium is a lightweight metal and the cathode reactant, oxygen, does not have to be stored in the battery, an Al-Air battery is considerably lighter than a comparable Lithium-Ion battery.
Any vessel moving in the water shall overcome different forces:
For displacement hulls, also its length is an important factor and in general terms, the longer the hull, the higher the speed it could achieve.
To provide propulsion power for a vessel, power and speed are broadly related by a near cubic equation. Many fishing boats tend to use relatively low powered two-stroke or four-stroke gasoline engines or diesel engines. The efficiency of this engines is between 20% to 25% for the former and up to 45% for the latter. But in all cases the actual power delivered to the propeller, to overcome the water resistance, is within 10% to 15% of the power available in the fuel, mainly due to the thermal and mechanical losses of the powertrain.
The electric motor and rechargeable battery are major components of electric vessels propulsion system. The output power from the motor is absorbed by the load, in this case the propeller represents the load to the motor, and boat speed corresponds to the thrust created by propeller rotation. Compared to conventional engines mounted in boats, electric motors have different performance characteristics described by torque-speed curves that produce the efficiency map of the device. An electric motor, with its constant torque can utilize a larger propeller than those used by combustion engines and the overall efficiency of the electric powertrain is therefore much higher.
Despite the big advantage in terms of efficiency, the most limiting factor for the use of a full electric powertrain on vessels is the low energy density of the current secondary battery solutions (mostly Lithium-ions). With RiAlAiR primary batteries this issue can be solved.
