US LNG exports are booming

 An interesting video from the FT (Financial Times, of London) about the boom in LNG exports from the US, mostly to Europe to substitute for the losses of gas from Russia.  It explains the process of creating LNG from natural gas, and shows how the US is now the world's largest exporter, with further increases likely.

Is the world locking in gas?  Prolly not, or at least not in the quantities implied in the question.  A grid powered by wind and solar will still need gas for cold, gloomy, windless periods  ("Dunkelflaute").    In countries with enough hydro, gas may not be needed, but even then gas will be necessary as back-up.  Until power-to-gas, i.e., converting surplus electricity to methane, becomes widespread, we will still need natural gas.  Producing surplus green electricity will require overcapacity in wind and solar, and we are a long way away from that now.  But by 2030, the need to curtail renewable output will be frequent, and in order not to waste it, we'll use it to make synthetic natural gas via the Sabatier process.  At that point, natural gas production will start to fall, and its place in the grid will be replaced by SNG.
