Presentation Outline • What is CHP? • South Hook History • South Hook CHP Concept • Conclusions

CHP = Combined Heat & Power • Same as “cogeneration” • Uses energy that would otherwise be wasted from thermal power production • CHP contributes 11% of ExxonMobil LaBarge CHP Wyoming, USA (100 MW) electric power in Europe, 8% in the United States

CHP Offers Many Advantages • Energy efficiency • Emissions reduction • Operating cost savings • Reliability improvement ExxonMobil Beaumont CHP Texas, USA (~500 MW)

…..CHP also has challenges • Brownfield construction • Location dependent on site heat demand • High capex vs stand- alone gas power plant ExxonMobil Antwerp CHP • Requires stable Belgium (125 MW) regulatory framework

South Hook LNG Terminal History • Located on Milford Haven in Wales • South Hook Terminal fully commissioned in 2010 • Joint venture with Qatar Petroleum International, ExxonMobil, Total

Current Terminal Operation • South Hook is a conventional LNG receiving and regassification terminal • Warm water, heated by fuel gas, is the medium for heat transfer in the vaporisers

South Hook CHP Concept • Residual heat from a gas-fired combined cycle plant could be used for LNG vaporisation

SHCHP - High Efficiency • Heat from combustion used 3 times 15% Waste Heat – Gas turbine generates power 30% for LNG – Steam turbine generates power Vaporization – Hot water vaporizes LNG 20% for LNG Steam Power 30% Vaporizers • CHP efficiency ~ 85% 35% for Gas Turbine Power 15% 35% 20%
