UPDATE 1-PetroSA puts coal-to-liquids plant on hold

(Adds details)

JOHANNESBURG Dec 11 (Reuters) - South Africa's state-owned oil company PetroSA said on Thursday it has put on hold its option to build a coal-to-liquids (CTL) plant, saying its feasibility needed more study.

The 80,000 barrels-per-day CTL plant was one of the options PetroSA was examining to expand South Africa's refining capacity by 2020.

"There are still some key issues related to carbon dioxide sequestration and water availability that need to be investigated," Vice President for Corporate Strategy Godwin Sweto told Reuters.

"It could still happen ... but the current thinking is that the earliest any size plant could be established would be at a later part of the next decade."

The company is proceeding with its other option, building the 400,000 barrels-per-day Coega oil refinery, which will be South Africa's largest when it comes on stream in 2014.

The refinery is part of PetroSA's measures to meet the government's mandate in its energy master plan to have the oil company supply at least 30 percent of the country's fuel needs by 2020.

Earlier on Thursday PetroSA reported a record revenue figure for the 2007/08 financial year of 11 billion rand, up from the 8.9 billion in 2007, boosted by high oil prices and a weaker rand.
