Other Ongoing Development Ef<strong>f<strong>or</strong></strong>ts<br />
Several <strong>com</strong>panies in the U.S. are <strong>com</strong>mitted to the development <strong>of</strong> CAES projects:<br />
• CAES Development Company, the parent <strong>of</strong> N<strong>or</strong>ton <strong>Energy</strong> <strong>St<strong>or</strong>age</strong>, is actively seeking<br />
other suitable CAES locations in the U.S.<br />
• Strata Power owns the reservoir rights to numerous aquifers near Chicago; several CAES<br />
plants are under consideration at these sites.<br />
• Ridge <strong>Energy</strong> <strong>St<strong>or</strong>age</strong> has an exclusive agreement with Texas Brine Company <strong>f<strong>or</strong></strong> access to<br />
several brine production sites in the U.S. that Texas Brine Company owns <strong>or</strong> has under lease.<br />
Ridge <strong>Energy</strong> hopes to utilize these brine caverns <strong>f<strong>or</strong></strong> the development <strong>of</strong> CAES plants.<br />
• The New <strong>Energy</strong> Foundation (NEF) has led CAES development in Japan with the<br />
construction <strong>of</strong> a 2-MW e , 4-hour CAES pilot plant in Kamisunagawa-cho, S<strong>or</strong>achigun,<br />
Hokkaido. Compressed air is st<strong>or</strong>ed at 580-1,160 psi in a shaft <strong>of</strong> an old coalmine. Research<br />
is ongoing to per<strong>f<strong>or</strong></strong>m a <strong>com</strong>prehensive evaluation <strong>of</strong> the per<strong>f<strong>or</strong></strong>mance <strong>of</strong> the pilot plant. NES<br />
is also collab<strong>or</strong>ating with the Japanese utility Electric Power Development Company Ltd.<br />
(EPDC) to develop a 35-MW e , 8-hour CAES plant.<br />
Current developers and vend<strong>or</strong>s<br />
As mentioned above, several <strong>com</strong>panies have been <strong>f<strong>or</strong></strong>med to focus on the development <strong>of</strong> CAES<br />
projects. The maj<strong>or</strong> <strong>com</strong>ponents, the intercooled turbo<strong>com</strong>press<strong>or</strong> and reheat turboexpander<br />
trains, are <strong>com</strong>mercially <strong>of</strong>fered by a number <strong>of</strong> suppliers:<br />
• Dresser-Rand <strong>of</strong>fers a 135-MW e turboexpander.<br />
• Alstom (that acquired ABB) <strong>of</strong>fers a 300-400 MW e turboexpander.<br />
• Dresser-Rand and Sulzer <strong>of</strong>fer full turbo<strong>com</strong>press<strong>or</strong> trains.<br />
These <strong>com</strong>panies are driving technical aspects <strong>of</strong> the CAES technology, and all have significant<br />
experience in this field:<br />
• Dresser-Rand supplied the <strong>com</strong>plete 110 MW e turbomachinery train <strong>f<strong>or</strong></strong> the McIntosh plant.<br />
• ABB supplied the turboexpander <strong>f<strong>or</strong></strong> the Hunt<strong>or</strong>f plant.<br />
• Sulzer supplied the turbo<strong>com</strong>press<strong>or</strong> <strong>f<strong>or</strong></strong> the Hunt<strong>or</strong>f plant.<br />
The other <strong>com</strong>ponents <strong>f<strong>or</strong></strong> CAES plants are obtained from vend<strong>or</strong>s <strong>of</strong> conventional equipment<br />
items such as electric mot<strong>or</strong>s/generat<strong>or</strong>s, small air <strong>com</strong>press<strong>or</strong>s, recuperat<strong>or</strong>s, etc. Table 4<br />
provides a list <strong>of</strong> CAES developers and equipment vend<strong>or</strong>s.<br />
Field Tests<br />
Be<strong>f<strong>or</strong></strong>e a CAES project can be developed, it is imp<strong>or</strong>tant to conduct field tests to determine the<br />
feasibility <strong>of</strong> a site <strong>f<strong>or</strong></strong> a full-scale plant. F<strong>or</strong> example, significant drilling w<strong>or</strong>k and probe<br />
