ENABLING THE SHIFT TOWARDS THE ECONOMY OF ELECTRICITY >>> THE ENERGY OF THE 21 ST CENTURY

StorEn Technologies Inc. Evolutionary Vanadium Flow Batteries (VFBs) proprietary IP an innovative design philosophy We are financially-viable in several applications, such as residential storage and power continuity e.g. telecom towers Incubated at the Clean Energy Business Incubator Program (CEBIP) at Stony Brook University in Long Island, NY

Our Vision Competitor focus on large gridscale container-sized batteries (utilities, grid operators) We focus on: Small, fully-integrated modules (like an appliance) To be volume-manufactured Plug-and-use Virtually maintenance-free To take advantage of: Phasing-off of net metering to promote self-consumption (tax credits, State subsidies, etc. )

Residential Storage Energy storage in a private (or commercial building) for: Storing solar energy Energy price arbitration (dual rates) Power-back (one patent on this)

The Lithium Proposition Currently lithium batteries have been deployed for energy storage projects, but: Cost of Li-ion increases linearly (no economies of scale) Loss of capacity over time High Depth of Discharge shorten life Fire & explosion - particularly manganese/cobalt (EVs) Low recyclability of metals (~6%)

Case Study Residential Storage Tesla Powerwall $6,600 @ 13.5kW $489/kWh (up in May 2108) Warranty: 10 years @ 70% capacity Cost/Cycle @ 100% capacity: $0.13 Cost/Cycle @ 85% capacity: $0.16

Our Solution StorEn 5/30 Module $500/kWh (target) $15,000 @ 30kWh (2.2X Tesla) 25 years or 15K cycles with no decay over time Economies of scale (decoupling power/energy) 100% reusable/recyclable electrolyte (asset) Non flammable, non explosive electrolyte Target Cost/Cycle @ 100%: $0.03 (below ARPA-E 2018 DAYS Program Target)

Conclusions Lithium is the ideal technology for power-intensive applications in mobility such as EVs and mobile devices but: Vanadium due to its long duration with no decay and economies of scale is the winner technology for energy-intensive stationary applications

Thermastable StorEn s Proprietary Geothermal Underground Design Efficient geothermal circuit Target +6% roundtrip efficiency Resilience in case of natural disasters Anti-theft and vandalism (ideal for remote locations e.g. telco towers)

Why Vanadium Flow? A DEMONSTRATED TECHNOLOGY WITH PROVEN FUNDAMENTALS DURABLE > 25 YEARS OR 15,000 CYCLES NO DECAY IN CAPACITY OVER TIME, UNLIKE LITHIUM 100% RECYCLABLE, UNLIKE LITHIUM 100% REUSABLE ELECTROLYTE 100% EXTRACTABLE VANADIUM CONTENT ECONOMIES OF SCALE, FOR HIGHER C-RATE with GREAT ROOM FOR TECH IMPROVEMENT & COST REDUCTION INCREASED POWER DENSITY > as a strategy to reduce stack cost INCREASED ENERGY DENSITY > as a strategy to reduce size IMPROVED COMPONENTS > higher performance e.g. electrodes BATTERY VOLUME MANUFACTURING > economies of scale COMPONENTS COST > breaking the NAFION monopoly

Our IP FOUR INTERNATIONAL PCT FILINGS (priority from our four US Provisional Applications - March 27 th, 2017) MULTIGRID (#PCT/US18/24414) > stack flow dynamic > 50% higher power density leading to a reduction in Stack cost EQUILEVELS (#PCT/US18/24531) > Electrolyte rebalancing method for reduced service costs, hence lower TCOs RESAFE (#PCT/US18/24483) > Leak elimination system for reduced service costs, hence lower TCOs THERMASTABLE (#PCT/US18/24512) increased round-trip efficiency in harsh climates plus OUR INDUSTRIAL SECRETS: Electrolyte Formulation & process; Electrode Nano-Coating (HiPower)
