• Energy security considerations and lower energy costs

• Requirements for emission reductionin power generation, industry and shipping

• Rapid growth of intermittent renewable power generation and escalating demand fluctuation. LNG/gas is a perfect balancing fuel.

Natural gas is conquering new marketsGlobal interest in LNG is driven by

By 2035 LNG will have overtaken

pipelines as the dominant form of

traded gas – BP Energy

Outlook 2035

Affordable energy security:

• Fraction of the cost of battery storage

• Limited lifetime with recycling/waste problem of batteries

• Superior to underground gas storage

• Less location specific as it can be built anywhere next to the pipeline

• Gas can be more quickly inserted to the grid

• Less risk of gas leakage

• LNG has considerably less volume than compressed natural gas

• Less environmental impact and a fraction of the cost of pumped hydro
