Nachman Shelef - Grid Scale Energy Storage

  1. 1. Grid-Scale Energy Storage Huge Opportunity Technology Barriers September 2011 Contact: nachman.shelef@gmail.com 1
  2. 2. Grid-Scale Energy Storage Huge long term opportunity Existing solutions are not good enough Technology breakthroughs are needed Barriers to mainstream adoption are coming down 2
  3. 3. Huge long term (2020+) opportunity After Wind and PV, the next huge renewable market is Storage 3
  4. 4. DRIVERS FOR THE MODERN GRID OFFERS A SOLUTION! DIGITIZATION OF INCREASED ENERGY STORAGE SOCIETY POWER QUALITY ECOLOGICAL DISPATCHABLE CONCERN RENEWABLES GROWTH IN INCREASED ENERGY ASSET CONSUMPTION UTILIZATIONFrom: DOE - IMRE GYUK
  5. 5. 5
  6. 6. Renewable Integration – the need 6
  7. 7. Renewable Integration – the need ERCOT wind curtailment 42% of the time EnStorage Confidential 7
  8. 8. Storage - a critical element of the future Grid 8
  9. 9. Grid Energy Storage ApplicationsBulk Storage (days – months, 10MW-1GW) Weeks Centralized Days Renewable IntegrationEnergy Storage Distributed 10KW-100MW) (1 – 12 hours, Hours End-User Grid Reliability Demand Management Renewable SmoothingPower Storage End-User Reliability (seconds – 2 hours, Minutes & 1KW-100MW) Grid Regulation Seconds 1KW 10KW 100KW 1MW 10MW 100MW 1GW 9 End-User Distribution - Transmission Generation
  10. 10. Sample Grid Energy Storage Applications 10
  11. 11. Many Grid Energy Storage Applications 11
  12. 12. Different technologies for different needs 12
  13. 13. Many Technologies installed for different needs 13
  14. 14. Only pumped hydro in significant use Cost important for mainstream adoption 14
  15. 15. Bulk Energy Storage Low Cost but Location Dependent Pumped Hydro  Limited growth opportunities  Most good locations developed Compressed Air (CAES)  Growth Opportunities  Dependent on Geology  Not pure storage 15
  16. 16. Cost is important for large scale adoptionToday – storage is more expensive than generation!Levelized Cost of Delivered Energy for Energy Storage Technologies Compared to CCGT 16Source - EPRI
  17. 17. Today costs higher than most mainstream benefits Application Value and System Cost Gap for All Technologies 17 Source - EPRI
  18. 18. Many Storage Technologiesbut today – not a lot of options that meet application needs and less that meet multiple application needs 18
  19. 19. Existing solutions are not good enough Technology breakthroughs are needed Requirements for Large-Scale Adoption of Grid-Scale Energy Storage • <$1,200/KW for a 6 hour AC system Cost • <$200/KWh DC Efficiency • >75% AC/AC • 10,000 deep cycles Durability • 15 year lifetime • <100ms to full power Speed • Fast charge and discharge • Not dependent on geologyLocation Flexibility • Transportable in containers Safety • No danger from hazardous or explosive material 19
  20. 20. The barriers to mainstream adoptionare coming down Storage Treated Like Other Renewable Solutions Storage recognized as a Incentives and Policy Barriers critical element of Mandates the grid Offset initial low Technology Price Barriers volume pricing Breakthroughs with Incentives and High Volume Performance Support for R&D Technology Barriers Breakthroughs 20
  21. 21. The likely Grid-Scale Energy Storagemarket situation 2015+High fuel pricesGHG (Green House Gas) marketCaps on new GHG emitting generatorsCaps on use of diesel generatorsMandatory reductions in peak capacityStandards or mandates for storageIndependent Storage Providers – ISPsStorage broadly used throughout the gridDeclining incentives
  22. 22. Key to become a market leader Technology breakthrough for “Grid Parity” storage  Start with competitive cost and potential for “grid parity”  Reduce costs with declining incentives  Become cost competitive vs. main alternative – peak generation Meet efficiency and durability targets to broaden field of applications Applications  Start with niche applications or bundled benefits  Test and qualify products at utilities or end users  Tailor products to each application 22
