Creating the Ideal Fuel
What if we could store energy forever, in a safe easily transported format, using one of the most abundant materials on earth, at energy densities greater than fossil fuels, with zero emissions and full circularity?
Powered by Impure Aluminum
As the AlumaPower Fuel Disc™ spins, it is slowly milled down and consumed in a reaction catalyzed by our water-based electrolyte and ambient air.
As the system operates, an off-product (Aluminum Trihydrate) is collected for reuse or resale.
AlumaPower’s Galvanic Generator™ design can easily and intuitively refuel by exchanging a spent fuel disc with a fresh one, not unlike changing a CD or DVD.
THE HISTORY
Background on Aluminum-air Batteries
Aluminum-air (Al-air) batteries are a well-established technology originally invented in the 1960s.
However, until now lingering technical challenges prevented them from mass adoption and limited their use to niche applications such as torpedoes, UUVs, and buoys.
AlumaPower has reinvented the Al-air cell design, otherwise untouched for 60 years, solving the key safety, convenience, and cost issues that prevented it from mass adoption.
Aluminum-air used to require high-purity expensive Aluminum anodes.
AlumaPower’s Galvanic Generators™ can use inexpensive impure Aluminum.
The ‘recharging’ process required labour intensive disassembly of fixed-plate anodes.
Our refuelling is now intuitive and is capable of operating continuously.
Frequent electrolyte replacement was required due to low electrolyte energy density.
We leverage internal fluid management to extend the life of the electrolyte.

TECHNICAL DETAILS
The Fundamentals of Aluminum-air
An Aluminum-air cell combines an Aluminum anode, an Oxygen reduction reaction cathode, and a water-based electrolyte such as Sodium Hydroxide.
Al +3OH– → Al(OH)3 + 3e– E = -2.31 V (vs. SHE)
Al(OH)3 + NaOH ⇆ Na+ + [Al(OH)4]–
02 + 2H20 + 4e– → 4OH– E = +0.40V (vs. SHE)
4Al + 3O2 + 6H2O→ 4Al(OH)3 E = -2.71 V
The practical potential obtained per cell is ~1.2V, with open circuit voltage greater than 1.6V. AlumaPower’s proprietary technology boosts output voltages to 12-24V from a single cell.
AlumaPower has partnered with a major global Aluminum producer to scale our proprietary scrap-to-fuel technology.
UNPACKING THE ALUMINUM ADVANTAGE
Leveraging the Existing Industrial Base
The smelting of virgin or primary Aluminum invests an incredibly high energy content into the metal. This is why Aluminum has long been referred to as ‘frozen electricity’.
AlumaPower’s technology can run on post-consumer scrap, such as that found in decommissioned cars. This waste stream will grow dramatically as we transition from the internal combustion engine to electric vehicles, giving us an abundant, low-cost feedstock.
As we scale, we will become early adopters of primary, lower grade, zero-emission Aluminum made with inert anode electrolysis. Together with other companies, we will create a zero-emission Fuel Grade circular Aluminum supply, capable of serving as much as 2x today’s global consumption of fossil fuel energy.
