MARKET TREND FOR LI-ION

1


The battery market (Avicenne)

Almacenamiento electroquímico con baterías de Li-ion

– Lead-Acid remains dominating battery technology

• In volume and value

• 4% annual growth (CAGR)

– Lithium-ion (Li-ion) becomes a significant challenger

– Li-ion=50% of market value in 2025

• Consumer 13bn$

• Automobile - xEV 15bn$

• Industria l 20bn$

Rechargeable battery market worldwide

2000-2025


Specific Drivers for Grid Storage

– Confirmed increase of Renewables

• Lion-share of Investments

• High share of EU mix by 2050

• Driven by wind & solar

– PV has reached competitiveness in many areas

– Grids reach level of RES saturation

Variable Renewable Energies Need for more flexibilities

Need for more ancillary services

Need for local energy management

ESS - Main Markets (1)

6

– Large Renewable plants & PV-Diesel

• Rationale: reach highest possible penetration of RES

in non interconnected or micro-grids, grid stability, fuel

savings

• Examples La Réunion Island: 9 MWh ESS for 9 MWp PV

Bolivia: 2 MW ESS for 10 MW PV-Diesel system

– Frequency Regulation

• Rationale: Cost effective alternative to fossil fuel based

primary reserves: CO2 savings, faster and more accurate

response, free production capacity

• Examples : SEPTA Phil.: 1 MW brake recovery &

frequency regulation

EDF France: 1 MW Frequency Regulation



ESS - Main Markets (2)

7

– End customer energy efficiency

• Smart buildings, residential PV & storage

• Rationale: Optimized facility energy management,

Demand Response, PV self-consumption / autonomy

• Examples SDEM Bretagne smart building, 50 kWh / 100 kW

with Schneider Building Energy Management

– Smart Distribution Grids

• Mainly Demonstration Projects

• Rationale: Integrate storage with high level of energy production,

smart grid technologies and DSM at distribution level

Avoid / defer grid upgrades

• Examples : ERDF Nice Grid & Venteea in France

ENEL several smart grid projects



ISLAND GRIDS : Vulnerability

– Variability of renewable generation can affect grid frequency

– Variations occur withing seconds



ISLAND GRIDS : Purpose and Benefit of Storage

– Overcome technical limits of integrating variable renewable generation

High power variability

•Ramp control

•Smoothing

Limited predictability

•Keep production in forecast window

Lack of inertia on islands

•Provide frequency support



SMART GRIDS - Support to PV & wind generation

0

Ramp rate control

Smoothing

Shaping

Peak Shaving / curtailment avoidance

Limit up & down ramp rates to

acceptable levels

Stable power output over

several hours

Provision of peak power to reduce

load on grid / Absorption of peak

generation

Keep production within given forecast window

Compensate short term power sags



Why Li-Ion for grid storage

•Changing and unpredictable power patterns

•Prolonged partial SOC

Suited to dynamic cycling

•Accurate SOC management avoids unavailability

•Efficient balancing

Accurate SOC indication in real-time

•Usable energy at Pmax is about 90%

•Charge and Discharge maximum powers available betwen 20°C and 50°C

Stable power capability for large SOC and T range

Excellent roundtrip efficiency

20 years lifetime is possible!



Best DC round trip efficiency in ESS market

– Intrinsic to NCA technology

– Lab tests by third parties show

• DC roundtrip efficiency > 95% for any power rate

• Efficiency stability at very different power rates, SOC, DOD, T

o 2% maximum difference

• Important for advanced energy management

o Precise knowledge of energy available in any condition

Saft calendar life and cycle life

– In years

– Depending on SOC and

temperature

– Depending on end of life criteria

– 7 000 cycles

– Depending on DOD and charge rate

– Depending on life criteria (70% of

initial capacity)
