Transcript Investor Overview

Plurion
Vision: “To be the dominant player in the multi billion
dollar market for high capacity electricity storage”
1
The storage market has arrived
•
•
•
•
Renewable Energy
•
•
Matches supply to demand
Relieves transmission instability
Arbitrage
• Low cost off peak generation stored
and sold at peak pricing
System Operation
• Peak lopping
• Reduced spinning reserve
• Removes transmission bottlenecks
The value of storage increases rapidly
with increasing energy price.
Renewable Energy is often out of sync’ with
demand
• Grid instability has forced Japan to require new wind farms to have storage
• Important US and EU markets are likely to follow with “Mandated Storage”
• AEP has placed an order for a 1GW (~$1Billion) NaS battery
• The current market for utility scale storage is $1-2Billion/year and this is
expected to grow to $10-20Billion by 2020

Storage technologies
Flow batteries are now acknowledged to cover the “sweet spot” – highest
storage capacity for 20kW – 10MW applications
3
Flow Batteries
•
electrolysers
Established high capacity battery
technology
•
•
•
•
Energy stored in liquid
electrolytes (tanks)
Power delivered through
electrochemical cells (cell stacks)
Power and energy are decoupled - adding tanks increases
capacity
Also known as
•
•
Reversible fuel cells
RedOx batteries

The concept is not new and numerous flow battery chemistries have been evaluated.
With the exception of Plurion’s technology all are now public domain
AIC’s strategy was to time formation of Plurion and patent filings to the emergence of real markets

Plurion - a plurality of ions
•
Consequently, Plurion has patent protection for a unique platform of
redox flow batteries
•
•
Plurion’s technology platform is based on the use of an organic acid
(MSA) in a flow battery
•
•
•
Each builds on Plurion’s core patents, AIC’s IP portfolio and a growing
platform of proven materials and equipment
This environmentally friendly acid makes it possible to produce much higher
concentrations of dissolved metal ions than is possible with mineral acids – in
turn this provides for higher energy and power densities.
MSA also makes it possible to utilize novel metal ion combinations (known as
a “RedOx couple”) which have a high cell voltage but are not possible with
mineral acids.
This positions Plurion as the only Flow Battery company holding patents
of matter in its core chemistries
