MGX Renewables Inc (CSE:MGXR) said Tuesday it has begun production of next-generation carbon-based cathode for its patented zinc-air fuel-cell battery technology.

In a statement, the Vancouver-based company said that, to date, it has produced 300 cathodes for use in its initial mass storage battery systems.

Each 5-kilowatt fuel-cell stack utilizes 50 cathodes, and MGXR said it plans scale-up cathode production to 36 megawatts of annual equivalent capacity with a minimum storage of 8 hours.

MGXR’s zinc-air fuel-cell battery technology can be used in a range of applications, which include renewable power storage, such as wind, solar and tidal, commercial and industrial backup applications, which could replace diesel generators, grid-scale energy storage and industrial-scale on-demand power.

Called the MGXR Energy Storage System, the technology is designed to deliver power in the range of 20 kilowatts-50 megawatts and energy storage in the range of 120 kilowatts-1 gigawatt over extended periods of time.

With the advantage of rechargeable zinc-air battery 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 zinc storage tank, a highly cost-effective and scalable solution now exists as an alternative to the lithium ion battery.

Here’s how the technology works: 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, zinc particles are regenerated, and oxygen is returned to the surrounding air.

Today's news gave a boost to MGXR's shares, which were up 23% to C$0.14 in morning trade in Toronto on Tuesday.
