Minerals Inc. ("MGX" or the
"Company") (CSE:
XMG /
OTCQB:
MGXMF /
FSE: 1MG)
announces
that its
wholly owned
subsidiary
MGX Renewables Inc. ("MGXR"), a
leader in the development of
zinc-air flow
batteries
for
applications requiring long duration,
high capacity
storage, has
successfully
generated
dendritic zinc
fuel using its new "linear" regenerator module.
The
fuel regeneration process requires application of an electric
current across the opposing electrodes of each regeneration cell.
Particles of zinc are "grown" on the cathode and oxygen is evolved
on the anode. The zinc
particles are periodically washed off the cathode using the same
electrolyte in which they were produced and then stored in the fuel
tank. The oxygen is then
released
into
the
atmosphere. A flexible number of regeneration cells are arranged in
series electrically to increase the capacity of the complete
regeneration module.
Successful
operation of the regeneration module represents the culmination of
development of the entire ZRS. This includes the mechanism for
generating the flow of electrolyte to wash the zinc particles from
the electrodes, the mechanism for collecting and transferring the
particles so produced,
and
the control system that manages the sequencing of all regeneration
functions. The control system is constructed from a custom
microprocessor control board plus proprietary embedded
software. All of
this
functionality has now been successfully integrated to enable the
production of the zinc particulate fuel.
The
operation and support of the regeneration module is the prime
function of the Zinc Regeneration Subsystem (ZRS)- one of the three
separately configurable subsystems of MGXR's unique zinc-air flow
battery. The two other subsystems are the Fuel Storage Subsystem
and the Power Generation Subsystem.

MGXR Energy Storage System
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 available
in
a
lithium-ion
battery.
Li-ion versus Zinc-Air
The
fundamental limitation of Li-ion is
a linear power to
storage ratio severely
limiting flexibility and vastly
increasing cost of storage even when limited output wattage is
required. This gives an overwhelming
advantage to MGXR's zinc-air fuel cell technology
in
high capacity, long duration commercial and industrial as well as
grid scale applications. 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. This creates large
scale arbitrage and
cost savings opportunities
as
well as a
policy
level
opportunity to enhance localized power infrastructure without the
need to build new power plants or transmission lines.

MGXR modular Energy Storage System (ESS)
Technology
The
MGXR ESS is based upon unique 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,
zinc particles
are regenerated,
and
oxygen is returned to the surrounding air.
Applications
The
flexibility of the MGXR ESS enables it to service a wide range of
applications. Typical examples include:
-
Storage and
smoothing current from renewable energy sources such as wind and
solar
-
Commercial,
industrial backup replacing diesel generators
-
Industrial
scale on demand power for peak shaving or standby
-
Grid scale
energy storage for energy trading and arbitrage
Architecture
The
MGXR ESS is designed according to a modular architecture that
enables a wide variety of system configurations to be created from
a small number of common subsystems. Each subsystem implements a
single element of the technology:
-
The
Zinc Regeneration Subsystem (ZRS) provides the recharging
function
-
The
Fuel Storage Subsystem (FSS) provides the energy storage
function
-
The
Power Generation Subsystem (PGS) provides the discharging
function
About MGX Renewables
MGX
Renewables has developed a patented zinc-air flow battery that
efficiently stores energy in the form of zinc particles and
contains none of the traditional high cost battery commodities such
as lithium, vanadium or cobalt. The technology allows for low cost
mass storage of energy and can be deployed into a wide range of
applications scalable energy storage applications.
The
zinc-air flow-battery is differentiated from other battery
technologies by its ability to decouple the relationship between
energy (kWh) and power (kW), by the very low cost of its zinc
energy storage medium, and by the inherent safety of its
chemistry.
Unlike
conventional batteries such as lithium-ion, which have a fixed
energy/power ratio, the technology uses a fuel tank system that
offers flexible energy storage to power ratios and scalability. The
storage capacity is directly tied to the size of the fuel tank and
the quantity of recharged zinc fuel, making low cost scalability a
major advantage of the flow battery system. In addition, a further
major advantage of the zinc-air flow battery is the ability to
charge and discharge simultaneously and at different maximum charge
or discharge rates since each of the charge and
discharge circuits is separate and independent. Other types of
standard and flow batteries are limited to a maximum charge and
discharge by the total number of cells as there is no separation of
the charge, discharge and storage components. For more information
