Presentation Outline

  • What is CHP?
  • South Hook History
  • South Hook CHP Concept
  • Conclusions
slide-3
SLIDE 3

CHP = Combined Heat & Power

  • Same as “cogeneration”
  • Uses energy that would
  • therwise be wasted from

thermal power production

  • CHP contributes 11% of

electric power in Europe, 8% in the United States

ExxonMobil LaBarge CHP Wyoming, USA (100 MW)

  • Energy efficiency
  • Emissions reduction
  • Operating cost savings
  • Reliability improvement

CHP Offers Many Advantages

ExxonMobil Beaumont CHP Texas, USA (~500 MW)

slide-5
SLIDE 5
  • Brownfield construction
  • Location dependent on

site heat demand

  • High capex vs stand-

alone gas power plant

  • Requires stable

regulatory framework

…..CHP also has challenges

ExxonMobil Antwerp CHP Belgium (125 MW)

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

– Gas turbine generates power – Steam turbine generates power

35% for Gas Turbine Power 20% for Steam Power 30% for LNG Vaporization

15% Waste Heat

– Hot water vaporizes LNG

30%

  • CHP efficiency ~ 85%

Conclusions

  • Gas plays a critical role in power generation
  • CHP can further extend the environmental

benefits of gas-fired power generation

  • Strong partnerships are key to identifying

innovative opportunities like South Hook CHP
