Relation with
Blue Energy
• Share technology development
• Unique issues: round trip efficiency,
depth of discharge, fluid compositions
• Advantages:
–
–
–
–
–
No pre-treatment needed
Can be further optimized (almost lab-conditions)
Higher energy density
Applicable everywhere, smaller scale as well
Less political, environmental, societal issues
