* S.Africa keen to develop shale gas industry
* Sasol wants to invest in the sector
By Ed Stoddard
JOHANNESBURG, March 10 (Reuters) - South African petrochemicals group Sasol Ltd is keen to invest in a domestic shale industry once it gets off the ground, its chief executive said, in a potential challenge to oil major Royal Dutch Shell.
South Africa's cabinet proposed new regulations to govern exploration for shale gas late last year after it lifted a 2012 moratorium on the activity in the central Karoo region.
Fracking in the region might tap what is believed to be some of the world's biggest reserves of the energy source and the government wants to develop an industry that it sees as a potential game-changer in Africa's largest economy.
"I am very excited because of the technologies we can bring to the table. We've got shale gas upstream experience in British Columbia," Sasol Chief Executive David Constable said on Monday.
"We want to get involved and participate and monetize that gas in country with gas to liquid, gas to power, gas to chemicals," he said after the group posted a 26 percent rise in half-year earnings.
Shell has applied for an exploration licence and once all of the new regulations are in place it is expected to be near the front of the line.
Constable said Sasol wanted to take part. "We are really interested in what is going in the Shell block and would love to farm in or take a piece of it. Shell is issuing profit warnings and pulling back capex right now," he said.
Shell said in January that it planned to cut capital spending to $37 billion this year from $46 billion in 2013, following a profit warning.
Shell was not immediately available to comment on Monday.
Constable said the government should take Shell's strategy into account.
South Africa's Public Investment Corporation (PIC), which is Sasol's biggest shareholder with a 13 percent stake in the company and manages 1.4 trillion rand ($130.3 billion) in civil servant retirement funds, has also said it wants a big slice of the shale pie.
Fracking involves pumping pressurised water, chemicals and sand underground to release gas trapped in shale formations and the prospect of it occurring in the semi-arid and sparsely-populated Karoo region, known for its big skies and scenery, has raised concerns anong conservationists.
Constable said Sasol's experience in British Columbia would enable the company to carry out the process "in an environmentally friendly fashion."
EARNINGS, DIVIDEND UP
Sasol said headline earnings per share (EPS) for the six months to the end of December increased 26 percent to 30.19 rand, in line with the group's trading update last month.
Earnings were lifted by a weaker rand currency and higher chemical prices.
Headline EPS is the primary measure of profit in South Africa and strips out one-off items.
Operating profit was hit by one-off items including a 5.3 billion rand impairment on Canadian shale assets prompted in part by poor prices in the North American gas market.
Sasol said it expected a slight strengthening in the rand, which would hurt earnings for the rest of the financial year.
The company raised its dividend by 40 percent to 8 rand per share, a record for a half-year payout.
