A Big Step For Low-Cost Mass Storage of Energy

Today, MGX Minerals Inc. announced significant progress made by its wholly-owned subsidiary ZincNyx Energy Solutions Inc., an energy storage company which has developed a next generation zinc-air fuel cell battery. According to today´s landmark news, ZincNyx has quadrupled the output capacity of its fuel cell modules (these "stacks" use zinc particles to generate electricity). On top of this remarkable achievement, the cost to manufacture the units has been reduced significantly as the load on the fuel pump has been reduced. ZincNyx President and CEO Suresh Singh, explained the paramountcy in today´s news: 

“This development is a further illustration of the flexibility of the ZincNyx system. Advances can be made to each component of the system without requiring simultaneous changes to the other components. In this case, the power generation capacity is increased without requiring simultaneous changes to the power regeneration capacity or the energy storage capacity.”

System Architecture

The ZincNyx zinc-air flow battery is comprised of three main modules- a regenerator module that uses electricity to charge particles of zinc, a fuel tank where the zinc particles are stored until needed, and a fuel cell module that uses zinc particles to generate electricity (see Figure 1).

Figure 1. Principle of Operation

Fuel Cell Module

The fuel cell module is comprised of a stack of identical cells. In the original implementation of the stack, each cell was capable of generating 100 Amps at approximately 1 Volt. A stack of 12 cells connected in series was thus able to generate 100 Amps at 12 volts, or approximately 1.25 kW.

The latest development of this technology doubles the area of each cell and enables up to 24 cells to be connected in series, thereby quadrupling the output capacity of a stack to 5 kW (200 Amps at 24 Volts nominal). An additional improvement incorporated in this iteration of the design is a streamlined electrolyte path that reduces load on the fuel pump. The new stack is designed for injection molding and die-casting from the outset, thereby reducing the cost to manufacture the unit.


ZincNyx has developed a patented regenerative 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.

Unlike conventional batteries, which have a fixed energy/power ratio, ZincNyx’s technology uses a fuel tank system that offers flexible energy/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 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.

Perfect Timing

Today´s disclosed technical advancements come at a perfect time because if you are a MGX shareholder in 47 days, on Friday June 29, you will receive the payment of a dividend: Shares of ZincNyx, which company has been proposed to become a standalone public entity to be listed on an exchange. Since announcing the record day 2 weeks ago, MGX´s stock experienced some wild swings in volume both in Canada and the United States. The market could be in the process of cleaning out its outrageous short positions as you rather want to be long on the record date (and not short).

What Short Sellers Are on the Hook For

According to Investopedia, the short seller on the record date will have to pay back the dividend out of his own pocket (which is impossible because MGX will still wholly owns this private company for some time after the record date): 

"Since that original investor who lent you the stock is no longer an actual shareholder, as the short seller, you are required to make up for any benefits the investor would have received had they actually still owned the stock. In other words, if a company pays a dividend to shareholders, the second investor who bought the shares from the short seller would get the dividend check from the company. But because the original investor is no longer a shareholder of record (since the second investor owns those shares now), then the short seller must pay the dividend out of his or her own pocket."

So instead of getting in trouble, short sellers are inclined to close out the short position by buying shares on the open market. The clock is ticking... 

Technical Perspective: Thrust Imminent

Updated Chart (15 min. delayed):

• As ZincNyx has become more attractive with today´s disclosed achievements, a run on the shares of MGX could occur as dividends are quite rare in the junior resource space and typically highly lucrative as no costs are involved for existing shareholders to receive "free shares" of a new public company. 

• What makes this spin-out even more attractive is that the spin-out shares are not expected to be subject to any statutory hold periods, i.e. the shares will be free trading on the first day of listing on an exchange.

• What makes this spin-out so interesting for shareholders to hold is that tens of millions of dollars have been invested into the ZincNyx battery storage technology over the last years by Teck Resources, the original private company that Teck acquired, and Canadian government funds. Importantly, the technology now looks ripe for demonstration in New York City later in 2018 and commercial deployment (initial target production of 1,000 units annually) by early 2019

• On April 4, MGX announced that the final assembly, site preparation and deployment are underway for its initial lithium extraction system for oilfield wastewater (petrolithium). The installation at 2 separate petrolithium sites in Alberta is expected to be largely complete by June 2018. Therefore, another good reason for investors to own the stock may emerge over the next few months.

Unrivaled Low-Cost Energy Storage Solution 

Most interestingly, the ZincNyx technology is unrivaled because compared to other flow battery designs (e.g. based on vanadium), ZincNyx is simpler (e.g. only 1 tank instead of 2) and has lower exposure to commodity prices. "This is a low-cost solution, and it will remain a low-cost solution”, Lazerson emphasized. While vanadium pentoxide prices have risen by over 20% in 2017, and ferrovanadium by almost 10%, the zinc price has rarely gone beyond $1.60/pound since 1989, trading at $1.55 last December. The 2 key ingredients in lithium-ion batteries, cobalt and nickel, were priced at $35 and $5.60 per pound, respectively, last December. 

ZincNyx has assembled an experienced team of professional engineers, scientists and business managers to execute the development and commercialization of a dependable renewable energy source. ZincNyx has developed a patented regenerative zinc-air fuel cell battery technology 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 company owns an intellectual property portfolio of more than 20 granted patents. It has strategic alliances with the National Research Council of Canada, the University of British Columbia and the Simon Fraser University. 

Energy storage is a growing industry in a fast-expanding market. From the ever-increasing need for renewable energy storage in developing countries to the requirement for reliable backup power in cities all over the world, ZincNyx offers an environmentally sustainable solution for a wide range of applications. ZincNyx has the lowest cost and most reliable technology for long run applications in the 10 kW to 1 MW segment. ZincNyx will target an estimated $10.5 billion market for its modular and scalable energy storage system: 

“Solar is going to be the key. I think, though, with the right partners, we’ve got something great here,” ZincNyx CEO Suresh Singh told Business in Vancouver. He expects the energy grid is going to change fundamentally in the coming years after companies spent years focusing on solar energy solutions. Because the price of solar has fallen so significantly recently, Singh said the focus is now being directed toward storing all the energy that is generated. Energy storage solutions have increasingly become a holy grail of sorts for tech companies.

According to Vancouver Sun: The market is driven mostly by other jurisdictions, such as California — where the utility regulator has mandated that renewable-energy suppliers start develop certain amounts of storage capacity — as well as China, Japan and Germany, where increasing amounts of renewable energy coming into the system can overwhelm their respective grids.

Energy storage is a billion dollar market with worldwide applications. With a cost-effective solution for energy storage, clean energy is made reliable and available as and when required with the ZincNyx technology. The technology allows for low cost mass storage of energy and can be deployed into a wide range of applications, including:

• Utility-scale storage and power grid load stabilization
• Long term backup power for industrial, commercial, and military facilities
• Remote location off grid and micro grid applications
• Diesel generator replacement or hybridization

ZincNyx’s technology consists of 3 main subsystems that use zinc and air to store energy in the form of zinc particles. 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.

Technological Breakthrough Accelerates Commercial Deployment

In January, MGX announced a major technological breakthrough by ZincNyx. Those that know about battery tech will immediately realize how important this breakthrough is, especially when considering that it’s patented. The long standing issue of metal-air batteries: Weak reliability due to the growth of zinc dendrites within the battery. The problem occurs when fine-threaded filaments of zinc crystals grow in unintended areas and may cause membrane ruptures or short circuits. 

The ZincNyx system is immune to this problematic phenomenon as it uses these zinc dendrites as fuel and consumes them as part of its normal operation. This technological breakthrough brings far reaching consequences because the avoidance of dendrite damage is the single most significant hurdle in the development and commercialization of zinc-air flow battery systems. As this technical challenge has now been mastered successfully, ZincNyx has already started the commercial design for the mass production of its scalable 20kWh capacity zinc-air mass storage battery. 

Competitive Edge

• The zinc-air battery is an innovative mass energy storage system which can be readily scaled from kilowatt to megawatt range.

• Most interestingly, the ZincNyx system is simple to manufacture in multiple locations using conventional methods – it does not require a Gigafactory!

• The main advantage is the low cost in comparison to other energy storage systems which traditionally include high-priced commodities such as lithium, cobalt and vanadium. The ZincNyx batterry solely includes zinc particles to efficiently store energy. The materials used in the manufacture of a full ZincNyx energy storage system are inexpensive and plentiful: zinc, magnesium, nickel, carbon, plastics.

Figure 1. Principle of Operation

• The technology emits no greenhouse gases or pollutants and does not contain any heavy metals. 

• It’s a closed system and because there is no buildup of dendrites it never needs to be refueled and it does not corrode. The zinc particles are charged by solar or wind, or whatever the charged zinc goes into the fuel tank, where the energy is stored and then on demand is pumped into the fuel cells and then back to the regeneration area to be recharged.

• Unlike conventional batteries, which have a fixed energy/power ratio, ZincNyx’s technology uses a fuel tank system that offers flexible energy/power ratios and scalability. The storage capacity is directly tied to the size of the fuel tank and quantity of charged zinc fuel, making scalability a major advantage of this flow battery system.

• The ZincNyx system is a true flow battery, thereby completely decoupling the energy and power capabilities of the system. The energy capacity can be increased simply by providing more fuel. This fuel (particles of zinc plus oxygen drawn from the air) is very inexpensive – estimated to be less than $25/kWh. Since the air does not need to be stored within the system, the size of the fuel tank is considerably reduced compared to other flow battery chemistries. 

• The ZincNyx system can also be described as a regenerative fuel cell – the fuel can be regenerated electrically and never needs to be replaced. The ZincNyx system provides the benefits of a hydrogen fuel cell without the need to transport and store hydrogen.

• The system is composed of 3 major subsystems: The zinc regeneration subsystem, the fuel storage subsystem and the power generation subsystem. Each subsystem can be sized according to the application requirements: Regeneration capacity (kW), energy storage capacity (kWh) and power generation capacity (kW). This is particularly important in photovoltaic applications where the duration of usable sunlight for regeneration may be limited to 6 hours or less. The separation of functions enables each subsystem to be optimised for its application and to utilise the most cost-effective and durable materials.

• The ZincNyx system does not require air conditioning since it operates above normal ambient temperatures (50-70°C).

• Another major advantage of the zinc-air flow battery is the ability to charge and discharge simultaneously and at different maximum charge or discharge rates as 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 size of the fuel storage system. 

Compelling Advantages
• Lowest cost energy storage for durations of 4 hours and greater
• Scalable, robust, reliable
• Insensitive to environmental and operational conditions
• Safe: No toxic, explosive or combustible materials or poisonous gasses
• Flexibility to optimize for power and energy needs

What others think about the ZincNyx technology:


On April 16, MGX announced "Expanded Capacity of Next Generation Zinc-Air Fuel Cell Battery": "ZincNyx Energy Solutions Inc. has developed new methods to expand the capacity of its zinc-air fuel cell battery as part of the mass production design phase..."

On April 18, MGX Minerals Inc. announced a ground-breaking partnership agreement between ZincNyx and New York based systems integrator Digital Energy Corp. According to the agreement, Digital Energy will install the ZincNyx battery system at a demonstration site in New York City and upon successful completion of the first project, both companies will develop additional installation sites and work to expand distribution of the ZincNyx technology in the US, as President and CEO of ZincNyx, Suresh Singh, explained: 

“We are delighted with this partnership with Digital Energy. Digital’s years of experience with system integration and energy generation will greatly enhance our ability to deploy energy storage solutions throughout the United States.”

The first project in New York City will demonstrate ZincNyx’s patented zinc-air flow-battery technology in combination with an onsite co-generation plant to reduce cost and increase revenue through multiple value streams, including peak shaving, demand response and economic dispatch. The ZincNyx flow battery chosen for this project employs a unique zinc-air chemistry that is safe for use in densely populated areas. The project will identify the operational and regulatory requirements to be satisfied for deployment in the state of New York.

Digital’s choice, amongst many high capacity batteries, is the zinc-air system that has long been recognized as highly advantageous due to its inherent safety, high energy density and abundance of its raw materials. The other unique advantages of the ZincNyx system, such as the ability to simultaneously charge and discharge, flexibility to optimize power and energy needs, low cost of energy for long durations and modularity, further simplified the decision. Vice President of Digital Energy, Jon Lilian, commented: 

“Digital is excited to partner with ZincNyx to bring lower cost energy storage solutions to New York State. We believe the ZincNyx flow battery product, along with revenue streams from the New York State REV initiative and the NYISO, will provide a high value proposition for this and future projects.”
