WIND EV FOSSIL STORAGE LOAD SOLAR PV ROOFTOP PV Electricity Storage provides a buffer between Electrical Generation and Electrical Load Balancing Technologies: Demand Management Thermal Storage, Chemical Storage Building Technology Proper Development of Energy Storage Requires Consideration and Interplay of different Areas Climate Politics Disasters Economics Resource Social Competition Movements Li-ion Batteries? Cycle life <<20years Safety Concerns. Low cost, market ready No Recycling! Tie-in with EV development No U.S. Manufacture Co Price Obstacles and Impediments to Sustainability: Safety, Reliability, Ecological and Sociological Issues, Re-Use, Recycling, Disposal 27 MW in 2017! Co Mining in Africa! A Stream of Trash! Safety is Essential!! Research and Statistics urgently needed How much should Liability Insurance be? - Can the Technology be improved? E.g. seatbelts - Should the Technology be replaced? E.g. H2 airships Safety should not be a Patch but part of Design! Ecological and Sociological Issues. Cheap for whom? Who will pay? Who will benefit? What is the Total Carbon Footprint? Will this help with Global Warming? Does it promote Social Equity? Is the Technology Sustainable? Re-Use, Recycling, Disposal EV Batteries retain ~80% Capacity • Reuse for Stationary Application? • or the Trash-heap? Recycling – is it commercially feasible Or does Entropy win again? The Midden is not an Answer! We must design for the Waste Stream!! → DOE Lithium-Ion Battery Recycling Prize To develop Safe, Inexpensive, and Environmentaly Benign Batteries We must look towards Earth-Abundant Materials Cost Goals for Focus Technologies Manufactured at scale Li-ion Batteries (cells) $250/kWh V/V Flow Batteries (stack+PE) $300/kWh ___________________________________________________________________ Zinc Manganese Oxide (Zn-MnO2) 2 Electron System $ 50/kWh Low Temperature Na-NaI based Batteries $ 60/kWh Aqueous Soluble Organic (ASO) Redox Flow Batteries (stack+PE) $125/kWh _____________________________________________________________________ Advanced Lead Acid $ 35/kWh New Technology Solutions will cut Costs, increase Safety and Reliability. Re-Use, Recycling, Disposal Issues will be Resolved. But, can new Technologies Prevail in the Marketplace??

Power (KW) = The rate at which the work is being done. Dan’s definition ES- KW – The Capacity of the Energy Storage System i.e, 1KW ES – KWh – The Capacity multiplied by the time (hour) rating of the system A 1KW 2 hour system = 2KWh Example - If 10 – 100 watt light bubs need to operate for an hour then: 10 x 100W = 1KW * 1 hr = 1KWh Energy Density (Wh/kg or Wh/L): used to measure the energy density of battery. Note: number often given for cell, pack, and system Generally: pack = ½ cell energy density, and system is fraction of the pack. $/KWh = Capital cost of the energy content of a storage device. $/KW – Capital cost of power content of a storage device. 8 Energy Storage System (ESS) is NOT the same as an Uninterruptable Power Supply (UPS) Traditional Traditional UPS UPS with generation 9 Energy Storage System (ESS) is NOT the same as an Uninterruptable Power Supply (UPS) Traditional UPS Grid-tied Energy Storage System Feeder (Microgrid Feeder configuration) Bi-directional Battery inverter Load Battery Load • Seamless Transition is Possible • Less Equipment = Lower Capital Cost • Does not require external signal to trigger • Easily Expandable Voltage source mode • Simple Controls • To date seamless transition is difficult 10 Elements of Battery Energy Storage Power Control Energy management Site Management Balance of Storage System (PCS) System (EMS) System (SMS) Plant • Storage device • Bi-directional • Charge / Discharge • DER control • Housing • Battery Inverter • Load Management • Synchronization • Wiring Management • Switchgear • Ramp rate control • Islanding • Climate & Protection • Transformer • Grid Stability • Microgrid control (BMS) • Interconnection • Monitoring • $ • Fire protection • Racking • $/KW • $ • Permits • $/KWh • $ • Efficiency • Cycle life NOTE: All–in can increase cost by 2-4x. 11 Lithium-ion Batteries Advantages High energy density Better cycle life than Lead - Acid Decreasing costs – Stationary on coattails of increasing EV. Ubiquitous – Multiple vendors Fast response SCE/Tesla 20MW -80MWh Mira Loma Battery Facility Higher efficiency* (Parasitic loads like HVAC often not included) Applications Traditionally a power battery but cost decreases and other factors allow them to used in energy applications SCE Tehachapi plant, 8MW - 32MWh. 12 Lithium-ion: Basic Chemistries Source: Z.
