    3. 3. Introduction  Government plan to introduce many Gigawatts of renewable power generation to the national grid by 2030.  These renewable technologies are highly volatile and, with the exception of tidal power, are virtually unpredictable.  The problem is that power is often generated when not required, and vice versa.  Only storage in the UK is Dinorwigg Hydro Pumped Storage System. 20/08/2013Wyre Energy Ltd - Preesall Salt Field CAES Proposal 3

    5. 5. Current Compressed-Air Energy Storage (CAES) Technology  When power is abundant, it’s drawn from the grid to compress air into an underground geological structure.  The air temperature rapidly increases in proportion with the gas laws and hence it must be cooled before entering the ground.  When demand is high (peak load times), the stored air is released back to the surface where it is heated and expanded.  In contrast, the decrease in pressure cools the air and hence this must be heated before it enters the turbine. 20/08/2013Wyre Energy Ltd - Preesall Salt Field CAES Proposal 5

    7. 7. ADELE Adiabatic Storage Project  Problem:  Temperature of the air following compression vastly increases, up to around 600°C which must be dissipated.  Conversely, thermal energy is lost following air expansion and hence air must absorb heat before entering the turbine.  RWE Power, General Electric, Züblin and DLR are currently researching possible ways to absorb, store and then reuse the thermal energy in the compressed air.  They are proposing highly insulated thermal towers made up stone, gravel and ceramics through which the newly compressed air will travel, exchanging its thermal energy.  Before the air from the ground passes into the turbine, it will pass through this tower absorbing some of the thermal energy, in a pre- heat operation. 20/08/2013Wyre Energy Ltd - Preesall Salt Field CAES Proposal 7

    9. 9. ADELE Adiabatic Storage Project  Estimated to increase efficiency up to 70%.  Take the compressed air at 600°C and store the thermal energy in towers up to 40m high.  Now delayed pilot plant to be built capable of:  Storing – 360MWh  Generating – 360MW electricity  The equivalent to 50 ultra-modern wind turbines spinning for 4 hours. 20/08/2013Wyre Energy Ltd - Preesall Salt Field CAES Proposal 9
    10. 10. Huntorf CAES Plant  Built in 1978 in Huntorf, Germany as the first CAES plant worldwide.  Paired with a Nuclear plant and conventional Natural Gas Turbine plant.  Compressed air from cavern mixed with natural gas and expanded through a turbine to produce electricity.  One cavern operates diurnally while the other is a ‘Black start asset’, providing protection for a shut-down of the Nuclear plant. 20/08/2013Wyre Energy Ltd - Preesall Salt Field CAES Proposal 10

    13. 13. McIntosh CAES Plant  Built in 1992 in McIntosh, Alabama.  Part of a factory consisting of two conventional gas turbines.  Start-up time of 14 minutes when first built.  Dresser-rand now boast 10 minutes to full power generation (5 minutes in emergency) and only 4 minutes to full compression operation. 20/08/2013Wyre Energy Ltd - Preesall Salt Field CAES Proposal 13

    16. 16. Preesall Salt Field  Production began as a result of the British Army’s exploration for water sources.  As a result of the discovery, exploration wells were sunk, with production beginning around the 1890’s continuing for the next 100 years.  Over 130 wells produced up to 3,500 tonnes of salt a week in 1900, peaking at 140,000 tonnes in 1906, making it the biggest salt producer in Britain. 20/08/2013Wyre Energy Ltd - Preesall Salt Field CAES Proposal 16
    17. 17. Failed Wyre CAES Applications  Cantaxx  Lancashire County Council rejected enquires in 2003, 2004 and 2008.  Opposition from local residents  Unsatisfactory geological surveys, failing to prove the area was suitable for high-pressure storage.  Halite Energy Group (Cantaxx Ancestor).  Further rejection in April, 2013 despite recommendation of approval by the examining authority, the Planning Inspectorate.  Appeal currently underway. 20/08/2013Wyre Energy Ltd - Preesall Salt Field CAES Proposal 17
    18. 18. Cantaxx/Halite Proposal  Construct 19 caverns of varying sizes via a leaching process  Total Volume of caverns:  14,580,917m3  Gas Capacity:  Storage capacity: 900,000,000m3  Working capacity: 600,000,000m3 20/08/2013Wyre Energy Ltd - Preesall Salt Field CAES Proposal 18
    19. 19. Wyre Energy’s CAES Solution • Due to the strong opposition from the public and unsatisfactory geological surveys from Halite, Wyre Energy plans to use compressed air as a means of energy storage, CAES. • This means there will not be a 1 million tonne gas bomb stored underground, such that we will gain support of local residents • A feasibility study will be conducted, which will concentrate on the geological study. • This means of energy storage will provide clean, renewable energy. 20/08/2013Wyre Energy Ltd - Preesall Salt Field CAES Proposal 19
    20. 20. Turbo-Expander Generators  Atlas Copco  Manufacturer of Turboexpander-Generators (TEG’s).  Provided two TEG trains to Turkish energy company Celikler Jeotermal Elektrik Uretim A.S, capable of producing 45MW of clean energy in a Binary Geothermal Plant.  Currently analysing data provided by Wyre Energy Ltd in order to determine available power from such a turbine. 20/08/2013Wyre Energy Ltd - Preesall Salt Field CAES Proposal 20
    21. 21. Energy figures  Average volume of the 19 caverns: 0.767 Mm3  Installed capacity per cavern: ~ 2990 MW  Load factor: 70%  Averaging at 2 hours peak generating per day, 365 days per year  Annual output per cavern: ~ 1528 GWh 20/08/2013Wyre Energy Ltd - Preesall Salt Field CAES Proposal 21
