Abu Dhabi, Aug 23 - Emirates Aluminium (Emal) and Abu Dhabi Gas Industries (Gasco) opened the natural gas pipeline at the world's largest single site aluminium smelter here, WAM news agency reported Sunday.

The pipeline, connected to the Emal power plant, will provide it with reliable and uninterrupted supply of natural gas.

'This is an important milestone for Emal,' said Emal CEO Duncan Hedditch.

Natural gas-fired power stations have 70 percent lower CO2 emissions than coal-fired power stations used in most aluminium smelters across the world. Aluminium smelting requires reliable, sustainable and long-term access to energy.
