    1. 1. CAES – New Development Projects Worldwide An Overview of Some of the Many CAES Projects Currently Being Carried Out Worldwide 20/08/2013
    2. 2. Overview  General Compression Technology  Larne CAES System, Northern Ireland  Iowa Stored Energy Park  San Joaquin County CAES System  Norton CAES System  Dresser-Rand  New York Power Authority Research  SustainX Demonstration CAES Project  Conclusions 20/08/2013 2Compressed Air Energy Storage Systems Worldwide
    3. 3. General Compression Technology  Have researched and designed the General Compression Advanced Energy Storage (GCAESTM) system1.  Based on reversible thermodynamics, they claim a near- isothermal process, covering both the compression and expansion stages.  Efficiency – 75%  Cost – $800 - $1000/kW2  Have a fully operational 100kW multi-stage plant in Watertown, Massachusetts.  Construction of second generation GCAES, 2MW, 500MWh system with wind turbine integration now underway in Texas. 20/08/2013 3 [1] Source: General Compression – Who We Are [2] Source: General Compression - Fuel-Free Geologic Compressed Air Energy Storage From Renewable Power - Task #1 Deliverable Report Compressed Air Energy Storage Systems Worldwide
    4. 4. Larne  A planned gas storage system by InfraStrata and North East Storage that was subject to heavy opposition due to the disposal of brine in the sea, amongst many other safety concerns3.  Gaelectric have now carried out tests to determine the feasibility of the area for CEAS.  £175million project  £10million set aside for feasibility study  Power Output: 140 - 300MW 20/08/2013 4 [3] Source: Larne Times – Test Data will Provide Data on Wind-Energy Storage Potential Compressed Air Energy Storage Systems Worldwide
    5. 5. Iowa Stored Energy Park  Planned project studied for 8 years to store wind energy through compression of air in sandstone aquifers below the ground.  Power Output: 270MW  $400million4  Project terminated in 2011 due to geology reasons. 20/08/2013 5Compressed Air Energy Storage Systems Worldwide [4] Source: Sandia Report – Lessons from Iowa
    6. 6. San Joaquin County CAES Site Testing  Pacific Gas & Electric Company (PG&E) spent three weeks conducting tests on a depleted natural gas reservoir, capable of storing 300MW of power lasting 10 hours5.  Engineers and geologists have been studying 10m sections of rock in order to determine the feasibility of CAES, as has to be the case with all CAES projects6.  Results are yet to be published. 20/08/2013Compressed Air Energy Storage Systems Worldwide 6 [5] Source: Energy Storage Exchange - Advanced Underground CAES Project w/Saline Porous Rock Formation [6] Source: PGE Currents- Electricity Out of Thin Air?

    7. 7. Norton, Ohio CAES Project  This project has been researched for over a decade now, changing company hands with current owners First Energy.  The proposal7:  CAES in a disused Limestone mine  Power Output: 270MW initially rising to 2700MW as more and more phases are built. 20/08/2013Compressed Air Energy Storage Systems Worldwide 7 [7] Source: First Energy Corporation – Alternative and Renewable Energy
    8. 8. Dresser-Rand  Dresser-Rand have recently been awarded the contract to proved the equipment for a 317MW CAES system in Texas, working in partnership with Apex.  Dresser-Rand also supplied the turboexpander turbines for the McIntosh CAES plant. 20/08/2013Compressed Air Energy Storage Systems Worldwide 8
    9. 9. New York Power Authority Research  Provide around 25% of the energy requirements of New York State, and are looking to supply renewable energy options to all their customers.  Mission statement:  “to advance the generation and utilization of renewable energy through project implementation, research and technology transfer”8 20/08/2013Compressed Air Energy Storage Systems Worldwide 9 [8] Source: New York Power Authority - Energy Storage Activities at New York Power Authorities
    10. 10.  Underground CAES feasibility study8  Power Output: 300MW  Compressor Power: 215MW  Storage Capacity: 10 hours  Cost: $700/kWh  Above ground CAES feasibility study  3 foot diameter 2 mile pipework  Power Output: 10MW  Storage Capacity: 2hours 20/08/2013Compressed Air Energy Storage Systems Worldwide 10 New York Power Authority Research [8] Source: New York Power Authority - Energy Storage Activities at New York Power Authorities
    11. 11. SustainX CAES Demonstration Project  Small start-up company who raised $14.4million and received a grant from US DoE of $5.39million, highlighting the recognition for such projects to be developed9.  A 50kW plant has already been built and now construction has begun on a 1MW, 4MWh plant10.  Built using SustainX’s patented Isothermal technology, boasting the lack of fuel and secondary heat sources involved.  95% efficiency in both compression and expansion. 20/08/2013Compressed Air Energy Storage Systems Worldwide 11 [9] Source: Gigaom - SustainX Raises $14.4M for Air Energy Storage [10] Source: US DoE – SistainX Inc - Isothermal Compressed Air Energy Storage
    12. 12. Conclusions  “Industry sources estimate that there are more than 40 such projects being contemplated over the next 5 to 10 years”  As can be seen through the examples provided throughout this presentation, compressed air energy storage is an area of heavy research with projects being set up by a number of companies.  The original technology is already proven by the plants at Huntorf and McIntosh, and now with advancements in technology far greater efficiencies can be achieved.  CAES systems provide an area of Engineering that could become the focal-point for many years to come, with investments richly rewarding. 20/08/2013Compressed Air Energy Storage Systems Worldwide 12
