2. Focus
Will energy storage impact the advancement of renewable energy technologies and will it aid in creating enough reliability to be a realistic supplementary source of power on the electrical grid?

3. Why Energy Storage?

4. Types of Energy Storage
Fossil
Natural Gas
Nuclear
Mechanical
Pumped Hydro
Electrochemical
Thermal

5. Energy Storage of Fossil Fuels
Underground
Gas reservoirs
Aquifers
Caverns
Old mines

6. Nuclear Energy Storage
Energy pellets in fuel rods – usually uranium
Lasts for about 6 years
Difficult to dispose of

7. Mechanical Energy Storage
Pumped Hydro reservoirs
Flywheel (FESS)

8. Mechanical Energy Storage
Compressed Air Energy Storage
Huntorf, Germany
Mcintosh, Alabama

9. Electrochemical Energy Storage
Supercapacitators
Sodium-sulfur,
Lithium ion
Lead acid
Notrees Wind Storage Project in Texas

10. Barriers Of Renewable Energy
Commercialization
Competing against older technologies
Acceptable sites
Permitting issues
Marketing
Financing for smaller projects
Lumpiness

11. Barriers Of Renewable Energy
Costs
Capital costs
Cost of energy
Limited labor experience
Technologies still not advanced enough

12. Implementation of Energy Storage Systems
Dependent on economics
Can help with variable energy generation
Can help offset peaks
Increased reliability

13. Implementation of Energy Storage Systems
Mira Loma Energy Station
Rows of Tesla Powerpacks
1.5 acre
Can Power 15,000 homes for 4 peak hours or 2,500 for 1 day

14. Uses of Energy Storage with Renewables
Solar
Usually used in homes
Usually uses Batteries

15. Uses of Energy Storage with Renewables

16. Advantages of ESS with RE
“Smoothing or Firming” power generation
Negligible fuel costs
Resiliency
Load Leveling
Peak shaving

17. Levelized Cost of Energy

18. Levelized Cost of Energy

19. Resiliency
Studies usually based on average wind power output

20. Load Leveling and Peak Shaving

21. Conclusion
Increases the value of Solar and Wind
Not economically viable yet
Storage helps mitigate Renewable energy barriers
