The conventional wisdom says liquefied natural gas is the future of energy — bridging the gap between the world abandoning fossil fuels and renewable supplies coming online. But that rosy outlook faces a reckoning. LNG is threatened by a pincer movement involving, ironically, the two old and new sources it’s supposed to bridge: coal and solar.

The cracks in the bridge could not have appeared at a worse time. The LNG market is about to witness its third big wave of increased supply in 20 years. If demand growth is weaker than expected, the only way the market would rebalance is via much lower prices.

The beauty of LNG is that once it’s been super-cooled to about minus 160 degrees, it transforms into a liquid that can be loaded into tankers and shipped around the world, very much like oil. Thus, LNG can reach any customer, breaking the historical limitation of gas pipelines.

Since the turn of the millennium, the global LNG market has absorbed every supply wave fairly quickly, taking two to three years. China swallowed a good chunk of the 2009-11 wave, when supply jumped by about 40 per cent after the completion of several projects in Qatar. Europe absorbed the 2016-19 wave, which came after a huge build-up in US export capacity increased global production by 45 per cent.

Now, a third wave, which is likely to extend from 2026 to 2030, is coming. It’s by far the........
