In Germany, the main function of LNG long term will be to smooth the transition of households from burning gas for heating to using heat pumps. As LNG is expensive, people who can will switch sooner than later. Also, rolling out heat pumps is going to take a long time and some people will be dependent on gas for as long as that is going to take.
A secondary role for LNG is to power gas peaker plants when renewables fall short. Mainly this can be done with existing gas plants. There's very little need for building more of those. Also, coal plants remain popular for this. Before the war the plan was replacing coal with gas plants. With current gas prices, that plan is out of the window and we're now looking at increased speed of the rollout of wind, solar, and batteries instead.
