ENABLING THE SHIFT TOWARDS THE ECONOMY OF ELECTRICITY

>>>

THE ENERGY OF THE 21ST 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 grid-

scale 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-intensivestationary 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

MULTIGRID™ (#PCT/US18/24414) > stack flow dynamic > 50% higher power

density leading to a reduction in Stack cost

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

EQUILEVELS™ (#PCT/US18/24531) > Electrolyte rebalancing method for

reduced service costs, hence lower TCOs
