CAES Air Energy Storage System Design Elements
TYPES OF VESSELS
Dresser-Rand 135 MWe CAES Turbo-Machinery Requirements
CAES Earth Storage System Design
DESIGN CRITERIA
All based on the concept of multiple geologic and hydrologic barriers.
CAES Issues in Solution Mined Salt Beds
CAES in Depleted Gas Fields
CAES Issues in Aquifers
Air Cycle Controlledby Hydrostatic Pressure
Air-Methane Mix in Reservoir
Air-Methane Oxidation Reaction
Air-MethaneFlammability Curve
600 mD Minimum Permeability
Advantage of CAES inDepleted Gas Field
Small Double Crested Dome
Multiple Thin Shale Lenses
Air Bubble Pressure Cycle
Why Dallas Center Failed as CAES Storage Vessel
Dallas Center CAES Analysis
Texas Salt Bed Issues
Reservoir Deliverability Issues Potential Chemical Reaction Issues
1. Double Crested Dome
2. 57 Shale Lenses in Sand
3. Could Not Develop Air Bubble
4. Sand Permeability to Low1. Limited Physical Size2. Removal of non-Soluble Impurities3. Cavity Stability4. Require Multiple Cavities to Work
1. Know it can hold air.
2. Know pressure history.
3. Know deliverability of wells.
