  2. Forward-looking statement This presentation contains forward-looking information that involves various risks and uncertainties regarding future events. Such forward-looking information can include without limitation statements based on current expectations involving a number of risks and uncertainties and are not guarantees of future performance of the Company, such as final development of a commercial product(s), successful trial or pilot of company technologies, no assurance that commercial sales of any kind actually materialize; no assurance the Company will have sufficient funds to complete product development. There are numerous risks and uncertainties that could cause actual results and the Company’s plans and objectives to differ materially from those expressed in the forward-looking information, including: (i) adverse market conditions; (ii) risks regarding protection of proprietary technology; (iii) the ability of the Company to complete financings; (v) the ability of the Company to develop and market its future product; and (vi) risks regarding government regulation, managing and maintaining growth, the effect of adverse publicity, litigation, competition and other factors which may be identified from time to time in the Company's public announcements and filings. There is no assurance that the DTCR business will provide any benefit to the Company, and no assurance that any proposed new products will be built or proceed. There is no assurance that existing “ patent pending ” technologies licensed by the Company will receive patent status by regulatory authorities. The Company is not currently selling commercial Energy Storage systems. Actual results and future events could differ materially from those anticipated in such information. These and all subsequent written and oral forward-looking information are based on estimates and opinions of management on the dates they are made and are expressly qualified in their entirety by this notice. Except as required by law, the Company does not intend to update these forward-looking statements. 2

  3. Disruptive technologies are emerging in the power sector 3

  4. Batteries What is a Battery? A device capable of storing electrical energy in the form of chemical energy and convert that energy into electricity. Why are batteries needed? Without batteries, solar panels and wind turbines become useless when the sun doesn’t shine, and the wind doesn’t blow. Batteries allow to use electricity whenever needed, not only when it is generated. 4

  5. Zinc8 Energy Solutions at a glance $72M CAD +280,000 man-hours since 2002 in R&D 20 US patents Extensive network Experienced + 4 pending of partners management team & BoD 5

  6. Introduction to Zinc8 Energy’s technology The Zinc-Air Flow Battery from Zinc8 Energy Solutions is an energy storage solution designed to serve a wide range of long- duration applications for microgrids and utilities. Our patented design and robust chemistry makes our system the most cost-effective, safest, and most flexible long-duration storage solution. The RFC system has a modular architecture that can be sized from 20 kW to the order of megawatts. 6 6

  7. How it works 3 2 1 20 U.S. patents issued and 4 more pending Certifications in process: UL1 973, UL 9540, UL 9540A, NFPA 855, EN-61000 series 1. Power from the grid or renewable source is used to generate zinc particles in the Zinc Regenerator . Oxygen is released to the atmosphere as a by-product. 2. The zinc particles are flowed to the Storage Tank and maintained in potassium hydroxide (KOH) electrolyte until required. 3. Whenever power is needed, the zinc particles are delivered to the Power Stack , recombining them with oxygen to generate electricity. The zinc oxide (ZnO) by-product is returned to the storage tank for later regeneration. 7

  8. Technology advantages Durable. Zero capacity fade over extensive lifetime Robust. Full discharge cycles. Same performance. Low cost. The longer the duration requirements, the lower the cost per kWh Safe. Non-flammable and non-toxic Sustainable growth. Stable supply chains for mass manufacturing The how behind the lowest cost for long-duration storage 8

  11. Capital Cost per installed kWh Comparison of different technologies for a 100-kilowatt battery system We strategically have chosen to target the 8-hour-plus market $1,000 $900 $800 $700 $600 $/kWh By decoupling the linkage between $500 Vanadium Redox power and energy, and using low-cost, $400 abundant materials, our system is Li-ion $300 8 hours capable of reducing its capital cost $250/kWh $200 dramatically for longer-duration 20 hours 30 hours 40 hours applications. $135/kWh $100 $110/kWh $95/kWh $0 0 5 10 15 20 25 30 35 40 45 50 Storage Duration (hours) References: 11 [1] Development of the all‐vanadium redox flow battery for energy storage: a review of technological, financial and policy aspects.

  12. Solutions Utilities Transmission Generation Distribution Microgrid Improved Operations ✓ ✓ Help optimize operations of diesel or natural gas gensets, reducing wear-and-tear and operating costs. Peak Management ✓ ✓ ✓ Reduce grid capacity needs during peak periods. Load Shifting ✓ ✓ Buy and store electricity at off-peak price to sell at peak price. Curtailment avoidance ✓ ✓ Avoid output curtailment at peak generation times and prevent loss of energy production. Non-Spinning Reserve ✓ ✓ Provide fast ramp-rate to meet grid requirement for online dispatch within a short delay of operating reserve. Back-Up ✓ ✓ Maintain grid resilience in the event of an outage . Renewable Energy Dispatch ✓ ✓ Control renewable energy generation according to market needs or at request of power grid operators. Increase Penetration of Renewables ✓ ✓ Store renewable energy production for peak and base load consumption. 12

  13. Why is long-duration so important? Battery duration portfolio States commitments in the US 100% Renewables 50-75% Renewables New York (2040) Oregon (2045) California (2045) New Jersey (2030) Hawaii (2045) Maryland (2030) Washington (2045) Vermont (2032) Maine (2050) New Mexico (2045) Colorado (2050) Washington DC (2032) CONCLUSION: The market needs affordable long-duration batteries! 13 References: [1] Tyson, Madeline, Charlie Bloch.
