<strong>Mini</strong> <strong>Mini</strong>-A-<strong>CAES</strong>: <strong>CAES</strong>: <strong>Compressed</strong> <strong>Air</strong> <strong>Energy</strong> <strong>Storage</strong> combined with two-level two level Thermal <strong>Energy</strong> <strong>Storage</strong>, size 1 to 10 MW<br />
Combining <strong>AG</strong> and <strong>TES</strong>: an Optimization Problem<br />
50 MW Wind Farm + <strong>AG</strong> A-<strong>CAES</strong> example (charge 8 hrs eq., discharge 2 hrs eq.)<br />
• Traditional <strong>Compressed</strong> <strong>Air</strong> Tanks<br />
• Experimental <strong>TES</strong>: Concrete Blocks<br />
Comments:<br />
• Low Efficiency (54%)<br />
• Experimental <strong>TES</strong><br />
• High Cost of Traditional<br />
Compressd <strong>Air</strong> <strong>Storage</strong> Tank<br />
but…<br />
• Total Investment Cost<br />
(2000 €/kW) less than NaS batteries<br />
• Size optimized for medium-small<br />
wind farms and/or large PV plants<br />
• Fast Response Time<br />
(few minutes)<br />
• Capable to balance RES<br />
• No siting problems (hydropumping,<br />
UG <strong>CAES</strong>, …)<br />
• No cycling problems<br />
• No fossil fuels<br />
• No fire/explosion hazards<br />
• No risks for the environment
