* Australian coal prices up more than 50 pct this year
* Asian LNG prices remain low as supplies soar
* Coal still more cost effective for Asian power generators
* Coal would have to rise to $100/mt for LNG to compete

SINGAPORE, Sept 22 (Reuters) - Natural gas producers have long yearned for a price spike in coal that would allow them to compete in Asian power generation.
Yet even a 50 percent jump in thermal coal prices this year has not been enough for liquefied natural gas (LNG) to gain an advantage over its dirtier fossil-fuel cousin.
The use of natural gas - when not supported by government policies - has typically been hampered in countries such as China, Indonesia and Vietnam by cheap coal as they seek the cheapest means possible to energize their emerging economies.
This year, things started to look different: an ongoing slump in oil and gas coincided with coal prices surging to nearly $75 per tonne from $49 in January, leading many to believe there would finally be a chance for gas to compete.
But even with Goldman Sachs (NYSE:GS) calling coal one of this year's "hottest commodities", and LNG prices not that far above a multi-year low of $4 per million British thermal units (mmBtu) touched in April, gas has not become competitive.
"I don't think (the coal price gains) are large enough to incentivise people to switch from coal to LNG, especially in Asia," said Mangesh Patankar, Asia-Pacific head of business development for energy advisory Galway Group.
"We need to see LNG prices falling further or coal prices rising further for that change to actually take place," Patankar told Reuters on the sidelines of an industry event in Singapore.
Asian spot LNG prices LNG-AS have fallen to less than $6 per mmBtu, from $20 per mmBtu in early 2014, even as coal markets have soared. benchmark coal prices GCLNWCPFBMc1 have risen this year to $73.60 per tonne, the highest since March 2015, driven by mining capacity limits in China that resulted in a surge in imports. calculations show coal would need to rise to $100 per tonne, or LNG to fall by another third, for the two main fossil fuels for power generation to achieve price parity.
Despite more LNG capacity coming online over the next few years, especially from Australia and the United States, Patankar said LNG would continue to struggle versus coal on a cost basis.
looks hard at this stage that on a long-run marginal cost level, an LNG-fired power plant can be cheaper than a coal-fired power plant," he said.
That's because coal prices are also likely to remain low.
"We don't see spot (coal) prices going higher from here as the Chinese government starts to loosen its existing production controls," Australian bank Macquarie said this week.
China this week loosened its recently introduced caps on domestic mining activity, leading many traders and analysts to expect a halt in the coal's recent price rally. CHART-Asian LNG vs coal prices
