MGX Minerals has entered the final phase of development for its next generation zinc-air mass storage systems. All components of the system have been designed, tooled and received with the exceptions of the fuel cell and regenerator plates which comprise the housings, and the final system enclosure. System level testing is expected to begin this month. All components are designed for mass production. Many of the most sophisticated and proprietary components such as the cathode are manufactured in-house.
MGXR modular Energy Storage System (ESS)
The MGXR ESS is a modular Energy Storage System designed to deliver power in the range 20 kW – 50MW and storage in the range of 120Kwh – 1GWh over extended periods of time. With the advantage of rechargeable zinc-air fuel cell technology, the system can be configured to support a wide range of discharge power, recharge power and duty cycle requirements. Since the energy storage capacity of the system is determined only by the size of the fuel tank, a very cost-effective scalable solution now exists as an alternative to the linear power storage ratio in the lithium ion battery.
In addition to containing no expensive commodities such as lithium or cobalt, the zinc air fuel cell battery has a much lower cost of storage reflecting a paradigm shift essentially eliminating the traditional linear fixed power / storage ratio and allowing for scalable power with highly flexible storage capacity at essentially any ratio, limited only by the physical parameters of the fluidized zinc storage tank(s).
The zinc-air fuel cell battery has completely decoupled power and storage subsystems with ratios of 1:5 up to 1:20 and conceptually 1:100, giving significant advantage in any scenario requiring more than a few hours of storage. This fills the need in both renewables storage as well as industry and grid scale opportunities in power acquisition and distribution along with the inherent benefits of clean steady power; with the potential to acquire power not just overnight and discharge on demand during the day but to take advantage of much larger swings in power demand and supply such as weekly, monthly, and potentially seasonal fluctuation.
Charging is also flexible and is scaled to match discharge but is a separate subsystem that can be scaled to match supply markets and timeframe of power availability whether long or short windows for power acquisition.
The MGXR ESS is based upon unique and patented zinc-air fuel cell technology. Energy is stored in the form of zinc particles, similar in size to grains of sand. When the system is delivering power, the zinc particles are combined with oxygen drawn from the surrounding air. When the system is recharging, the zinc particles are regenerated and the oxygen is returned to the surrounding air.
The flexibility of the MGXR ESS enables it to service a wide range of applications such as storage and smoothing current from renewable energy sources such as wind and solar.
