  1. 1. ENERGY STORAGE SYSTEM SUBMITTED BY NAME: AMIT EKKA REGD NO: F22-4005 BRANCH: MECHANICAL SEMISTER: 1ST
  2. 2. INTRODUCTION • IT IS PARTICULARLY IMPORTANT FOR THE DEVELOPMENT AND INTEGRATION OF RENEWABLE ENERGY TECHNOLOGIES. SOME RENEWABLE ENERGY SOURCES HAVE INTERMITTENT GENERATION PROFILES, WHICH MEANS THAT ELECTRICITY IS ONLY PRODUCED WHEN THE SUN IS SHINING OR WHEN THE WIND IS BLOWING. THIS CREATES SUPPLY AND DEMAND DISCREPANCIES BECAUSE CONSUMERS MAY STILL REQUIRE ELECTRICITY WHEN RENEWABLES SOURCES ARE NOT PRODUCING. • ENERGY STORAGE ENABLES A LOWER-COST GENERATING SOURCE TO PRODUCE ELECTRICITY AT A DIFFERENT POINT IN TIME TO BE STORED AND THEN USED TO MEET TIMES OF PEAK DEMAND. THIS ‘FLEXIBILITY’ HAS THE POTENTIAL TO TRANSFORM HOW WE PRODUCE AND CONSUME ELECTRICITY.
  3. 3. ENERGY STORAGE SYSTEM • INTRODUCTION • WHAT IS ENERGY STORAGE SYSTEM • NEED OF ENERGY STORAGE • TYPES OF ENERGY STORAGE • BATTERY ENERGY STORAGE SYSTEM (BESS) • HYDROGEN ENERGY STORAGE SYSTEM (HESS) • PUMPED HYDRO STORAGE PLANT IN INDIA • COMPRESSED AIR ENERGY STORAGE SYSTEM (CAES) • MECHANICAL ENERGY STORAGE SYSTEM (MESS) • STATEGIC APPROACH • BARRIERS • CONCLUSION
  4. 4. WHAT IS ENERGY STORAGE SYSTEM • ENERGY STORAGE SYSTEM CAN ACTUALLY STORE ENERGY AND USE THE STORED ENERGY WHENEVER THE NEED ARISES. • AS THE NEED FOR CLEAN ENERGY ARISES, THE NEED TO REPLACE CURRENT EXISTING POWER PLANTS HAVE BECOME A GLOBAL ISSUE.
  5. 5. NEED OF ENERGY STORAGE SYSTEM • SUPPLY AND DEMAND MISMATCH. • UTILIZE STORAGE FOR PEAK PERIODS. • RELIABLE POWER SUPPLY. • REDUCE THE NEED FOR NEW GENERATION CAPACITY. • ELECTRICAL VEHICLES • EMERGENCY SUPPORT.
  6. 6. TYPES OF ENERGY STORAGE • ENERGY STORAGE SYSTEMS ARE THE SET OF METHODS AND TECHNOLOGIES USED TO STORE VARIOUS FORMS OF ENERGY. • THERE ARE MANY DIFFERENT FORMS OF ENERGY STORAGE • BATTERIES: A RANGE OF ELECTROCHEMICAL STORAGE SOLUTIONS, INCLUDING ADVANCED CHEMISTRY BATTERIES, FLOW BATTERIES, AND CAPACITORS • MECHANICAL STORAGE: OTHER INNOVATIVE TECHNOLOGIES TO HARNESS KINETIC OR GRAVITATIONAL ENERGY TO ST ORE ELECTRICITY • COMPRESSED AIR: UTILIZE COMPRESSED AIR TO CREATE ENERGY RESERVES. ELECTRICITY CAN BE CONVERTED INTO HYDROGEN BY ELECTROLYSIS. THE HYDROGEN CAN BE THEN STORED AND EVENTUALLY RE-ELECTRIFIED. • PUMPED HYDRO-POWER: CREATES ENERGY RESERVES BY USING GRAVITY AND THE MANIPULATION OF WATER ELEVATION • THERMAL: CAPTURING HEAT OR COLD TO CREATE ENERGY • THE CHOICE OF ENERGY STORAGE TECHNOLOGY IS TYPICALLY DICTATED BY APPLICATION, ECONOMICS, INTEGRATION WITHIN THE SYSTEM, AND THE AVAILABILITY OF RESOURCES.
  7. 7. BATTERY ENERGY STORAGE SYSTEM (BESS) • BESS FOR PV SYSTEMS: DC/DC CONVERTERS ARE USED PROVIDING DC LINK VOLTAGE TO THE INVERTER FROM BATTERY. • BESS FOR UTILITY: BIDIRECTIONAL INVERTER (DC/AC OR AC/DC) ARE USED. DC/AC CONVERSION TO AC GRID AND AC/DC CONVERSION TO CHARGING BATTERY
  8. 8. HYDROGEN ENERGY STORAGE SYSTEM (HESS) • HYDROGEN AS FUEL • ELECTROLYSER : DECOMPOSING WATER TO H AND O2 THEN H STORED IN A HIGH PRESSURE TANK AS FUEL STORAGE • FUEL CELL: GENERATING DC POWER BY REACTION OF H AND O2 AND WATER OR STEAM RELEASED AS WASTE • HYDROGEN ABLE TO BE TRANSPORTED VIA GAS PIPES • OVERALL HESS AROUND 30% EFFICIENCY WHICH IS MUCH LOWER THAN BESS
  9. 9. PUMP HYDRO STORAGE SYSTEM • EMPLOYS OFF PEAK ELECTRICITY TO PUMP WATER TO A RESERVOIR OF LOW ELEVATION TO HIGHER ELEVATION AND RUN DOWN TO HYDRO TURBINE TO GENERATE ELECTRICITY.. • CAN BE SIZED UPTO 1GW. • EFFICIENCY 80-85%. • LIFE 50-60 YEARS. • SITING ISSUE • EXPANSIVE TO BUILD.
  10. 10. PUMPED HYDRO STORAGE PLANT IN INDIA
  11. 11. COMPRESSED AIR ENERGY STORAGE SYSTEM(CAES) • AIR IS COMPRESSED AD STORED AND IS LATER USED IN GAS TURBINE STATIONS. • CAN BE SIZED UNDERGROUND 400 MW. ABOVE GROUND 3-50 MW. • EFFICIENCY 70%. • LIFE 30 YEARS. • SITING ISSUE. • EXPANSIVE TO BUILD.
  12. 12. MECHANICAL ENERGY STORAGE SYSTEM (MESS) • FLYWHEELS • ENERGY IS STORED IN THE FORM OF MECHANICAL ENERGY. • LIFE 20 YEARS. • EFFICIENCY 70-80% • AS MOST ENERGY IS LOST DUE TO FRICTION FLYWHEELS ARE OPERATED IN ENCLOSED VACUUM SPACE. • LOW ENVIRONMENTAL IMPACT. • SUITABLE FOR SHORTER DURATION • HIGH COST. • ADD MORE WEIGHT TO CARS.
  13. 13. STRATEGIC APPROACH
  14. 14. BARRIERS
  15. 15. CONCLUSION • ESS FOR BALANCING GRID IS A LONG TERM SOLUTION. • RESEARCH CENTERS SHOULD BE ESTABLISHED TO CARRY OUT THE RESEARCH AND FOR TESTING IN THIS FIELD. • COUNTRIES WHO HAVE NOT YET EXPLORED THEIR RENEWABLE ENERGY POTENTIAL SHOULD EXPLORE POTENTIAL OF STORAGE IN PARALLEL. • PROPER POLICIES SHOULD BE DEVELOPED. • EXPLORE PUBLIC PRIVATE PARTNERSHIP
