Plurion (Version 4) Vision: “To be the dominant player in the multi billion dollar market for high capacity electricity storage”
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
electrolysers Electrolyte tanks Flow Batteries • Established high capacity battery technology • Energy stored in liquid electrolytes (tanks) • Power delivered through electrochemical cells (cell stacks) • Power and energy are de-coupled - adding tanks increases capacity • Also known as • Reversible fuel cells • RedOx batteries Diagram of Plurion’s 65kW module
Some Flow Battery Chemistries • 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 • Each builds on Plurion’s core patents, AIC’s IP portfolio and a growing platform of proven materials and equipment • Plurion’s technology platform is based on the use of an organic acid (MSA) in a flow battery • 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
Some of Plurion’s Patent Filings A&P = patent approved and published; A = approved but not published; Pen = patent still being examined; C = continuation of approved patent.
Putting this in perspective Comparative cost analysis assuming equivalent volume production each using a manufactured product
Product Vision • 250kW plug and play units based on 65kW sub-module • Competitive Role Model • Simple cycle gas turbine peak plant • Reliable, manufactured, mission critical • Leased not sold Layout of 65kW sub-module Layout of 250kW module
