Compressed Natural Gas
CNG has a long history of safe transportation onshore• Gas pipelines transport compressed gas• 30 year history of transporting CNG by truck• CNG fuels more than 15 million motor vehicles (Amer. Gas Assoc.)
Large-scale marine CNG transport• Historically unrealized due to limitations of small pressure vessels• Sea NG’s Coselle® System makes large-scale, ship transportation of
CNG safe, simple and economic• New application of tried and tested technology

MARKET
12CONFIDENTIALCONFIDENTIAL
A worldwide reduction in flared gas
• Reduce offshore flaring• Over 10 billion cubic feet of gas is flared worldwide every day• Anti-flaring legislation will limit deepwater development
• Market stranded gas • Export to markets not suitable for pipeline or LNG• Export from gas fields not suitable for LNG or pipeline • Able to monetize several small reserves in sequence by
moving fleet from field to field over time
13CONFIDENTIALCONFIDENTIAL
Challenges for coastal based energy systems
• Often isolated
• Limited demand
• Not connected to continental grid
• Limited footprint for infrastructure
• Environmental imperative
14CONFIDENTIALCONFIDENTIAL
Value for power and industrial consumers
• Reduction of fuel cost
• Diversification of fuel supply with natural gas
• Reduction in operating and maintenance costs
• Reduction in emissions
• Capture of carbon credits
15CONFIDENTIALCONFIDENTIAL
Environmental benefits for fuel substitution
• A power plant switching from HFO to CNG reduces:▼ Carbon dioxide (CO2) by 28%▼ Nitrogen oxides of (NOx) by 78%▼ Particulates by 92%▼ Sulphur oxide of (SOx) by 100%▼ Mercury by 100%
• Clean Ship technology• Sea NG’s ships run on clean-burning natural gas

17CONFIDENTIALCONFIDENTIAL
Applications for marine CNG
Marine CNG delivers natural gas to regional energy markets
Active and potential project development
• Fuel switching: Delivering low-cost natural gas to liquid fuel customers
• Transportation of “stranded” offshore natural gas
• Transportation of offshore associated natural gas
• Bridging price arbitrage between regional energy markets
