Natural gas is playing an increasingly key role in China's energy transition as the country scales up its renewables drive.

As part of its transition to low-carbon development, the country's onshore focus is switching from expanding oil developments to maintaining its current crude output and increasing natural gas throughput.

This will see the country's crude production peak soon at around 200 million tonnes (1.47 billion barrels) per year, with onshore natural gas output increasing to 250 billion cubic metres by 2030 from last year's 189 Bcm, according to China State Oil & Gas Strategy Research Centre official Zhang Guosheng.
