Battery Storage: 240 GW Global Capacity by 2030*
Grid-connected energy storage market is set to “explode” to an annual installation size of 6 GW in 2017 and over 40 GW by 2022
Stationary Energy Storage will grow to $2.8 Billion annual market in 2020 Batteries for Micro-hybrids will grow to a $6.1 Billion annual market in 2020
Global market for energy storage for will grow to 1,040 GWh by 2030 (>$400B)Energy storage is the “Holy Grail” in addressing the intermittency problem of renewables
Battery storage solutions are a “game-changer”
Texas utility Oncor will seek state regulatory approval for up to $5.2 Billion in distribution grid-connected batteries, with deployment set to start in 2018 – 15GWh of batteries!

Key Question: What Are Barriers to Widespread Adoption?
1. Initial Cost – Minimize financial risk, accelerate payback time, open up the market size
2. NPV of cost and benefits – $/kWh throughput, recycling value (or cost) at end of life
3. Validated Performance – Will they last 10 years? Bankability. Replacement costs. Future-proof.
4. Safety and Acceptance – Customers, Regulators, and Environmentalists; On-site permitting
5. Connect Multiple Value Streams – Improve ROI and drive faster adoption; more power, more life

Factors Impacting Adoption - Analysis
Li-IonHP, high lifeMid-gradeHE, low lifeCost varies $350-$750/kWhTesla disruption
ExoticsFlow, Zn, Fe, V,…Promising low cost in the future
Advanced Lead $150/kWh now
Lets look at the model more deeply
Typically used for grid-scale, but not the key driver in residential
Payback time more important in behind-the-meter applications – minimizes financial risk
Cycle life plus calendar life (can Li-Ion last 10 years?)
Life at high rates is also important
Advances in PbA (PLM™) are enabling
System design to minimize replacement cost
Level of comfort (residential, commercial, grid)
History and precedence
Permitting (fire departments)
Proven electrochemistry of advanced PbA
Need both high and low rate capability
Behind-the-meter aggregation
Multiple cycling modes (DOD, rate)
Controls features maximize value

PLM™ Battery - Advances in Cycle Life of Low Cost Batteries
Gen 1 – available now1,250 Cycles @100% DOD, 2C rate2,000 Cycles @80% DOD, 2C rate$150/kWh initial cost
Gen 2 – R&D2000 Cycles @100% DOD, 2C rate ~3,000 Cycles @80% DOD, 2C rate PLUS 30% higher initial energy at the same cost to produce.
Higher Energy + Longer Life = 70% More Energy throughput at the same cost
Gen 1
Gen 2

Battery-specific Analysis by Application Profile
8
A detailed analysis of the specific application is required to determine the NPV life-cycle cost
6-factor Analysis Provides Insights on Battery Chemistry & ROI
Iterative Cost Model Reduced capacity over life vs. a fixed energy
requirement results in a higher DOD use
The higher DOD faster capacity reduction
Iterations calculate incremental and accumulated capacity loss with more accuracy
The analysis introduces a “replacement event” when the capacity is no longer meets application need or at “end of life”
This analysis includes: Cycle life
Varying Depth of Discharge with capacity loss
C-Rate (power to energy ratio)
Round Trip Efficiency
Calendar Life
Initial and replacement cost
