How it's used
Scientific terms like this are often borrowed directly from written Chinese, but in casual conversation, people usually refer to the sources of the gas instead. You will hear people talk about 煤氣 or 沼氣 much more frequently than the chemical name itself. Using this term signals a more formal or academic context, such as discussing environmental science or climate change.
