Securing Australia’s Future Energy with Storage
Anand I. Bhatt | Research Team Leader Australian Energy Storage Alliance –Networking Evening – Thursday 26th March 2015 ENERGY FLAGSHIP
What’s happening in Australia’s grid?
Cost of electricity↑
Cost of solar PV & energy storage (ES) continue ↓
Big opportunity for energy storage

Energy Storage and the Grid
Characteristic properties of different energy storage systems lend themselves
to varying roles in the “grid”
Strongly dependent on either energy storage or power delivery or mixes thereof

Maturity of different ES technologies
From the various technologies available some are feasible for applications at
present, whilst others require further development/mass production or
fundamental R&D
A wide range of technology options exist
Each technology has advantages and disadvantages and potential different uses on the grid

Australian Energy Stakeholder Views
CSIRO has surveyed 122
stakeholders from across
the energy sector including:
• Technology companies
• Representative industry bodies
• Government
• Utilities
• Research institutes
Key findings:
• Need more active industry participation with proven pilot projects to increase confidence in
technology
• Lack of regulatory policies
• 55% of industry respondents believe Li-ion batteries are the most appropriate option
• Desire for standard evaluation method for different storage technologies

What is CSIRO doing?
Developing software tools to model energy storage technologies
Develop additional evaluation profiles based on real application data
Test and evaluate a range of different battery technologies : Pb‐acid, Li‐ion, NiMH, advanced Pb‐acid
Modelling LV/distribution network to determine ES locations
CSIRO Energy Storage Technology Evaluation Method
Accelerated testing profile developed based on real application data
Size and technology independent
Variety of test scenarios being developed, keen to get stakeholders involved

Evaluating energy storage solutions
No agreed international standards or processes evaluate technologies for PV-storage
Overseas example of solar evaluation profile for energy storage technology evaluation
Evaluation of Energy Storage systems
By having a good understanding of generation and Australian conditions, accurate
evaluation protocols can be established to identify ES technologies

Summary
• Technologies have to be able to cope with Australian climate and geographic limitations
• Will affect technology lifetimes
• Evaluation of technologies needs to be accomplished – CSIRO has developed a Australian specific, technology independent evaluation method
• No internationally agreed methods to do this
• Profiles based on real application data – test under similar conditions to application
