China has claimed a major energy breakthrough, but its eco credentials are dubious at best. Researchers say they managed to extract gas from flammable ice in the South China Sea. A frozen mix of natural gas and water known as methane hydrates, the ‘breakthrough’ is expected to revolutionize the future of energy. We’re not sure that’s a good idea.
Flammable ice could be our planet’s final great source of carbon-based fuel, according to the BBC. Vast deposits can be found under essentially every ocean. But it’s incredibly difficult to extract gas from flammable ice – in part because it catches fire so easily – a lighter held up next to the ice will do the trick.
Japan so far has led the way in working to mine the potential energy source, but China’s latest efforts could mark a milestone on the path to extracting gas from methane hydrates. Chinese media said the country had succeeded in extracting an average of 16,000 cubic meters of gas per day in the South China Sea.
Scientist Praveen Linga of the National University of Singapore told the BBC, “Compared with the results we have seen from Japanese research, the Chinese scientists have managed to extract much more gas in their efforts. So in that sense it is indeed a major step towards making gas extraction from methane hydrates viable.”
But Linga warns extraction must be done carefully. Methane could escape from the methane hydrates during extraction, which could harm the planet as methane holds greater potential to affect climate change than carbon dioxide, according to the BBC. It’s hard to tell if flammable ice extraction will fall into the pitfalls of the oil and gas industry, with greed taking precedence over our planet. The BBC also described flammable ice as a very energy intensive source of fuel.
Linga says there’s still a long way to go, and he said realistic commercial options might be ready in 2025 at the earliest.
