Equipment Required

Standard Gas Plant – Low CAPEX

Small Carbon Footprint

Large Cryogenic – High CAPEX

Larger Carbon Footprint
Pricing Delivered Price Tied to U.S. Gas Market: stable, and ability to lock in long term pricing

Delivered Price Often Tied to Global Crude Pricing: unpredictable and costly

Sloshing During Shipment None - Cargo Containment is 100% full, therefore no sloshing issue Presents challenge during Operations
Boil-Off During Shipment and Storage None - Cargo Containment is 100% full, therefore no free surface area or boil-off issues

Presents challenge during Operations

Added Expense
