Part of the speech the chancellor gave was also the announcement to build two new LGN terminals „pretty quickly“ in order to gain more independence. This of course goes hand in hand with a general push to more renewables.
You can import gas via pipeline (from Russia) or in liquid form (LNG) from Qatar and others. You need a terminal to deal with LNG which is under high pressure and very low temperatures.
It will take longer to move away from gas as an energy source. That will happen over next decade at least.
The idea is to use these to import LNG from the US and Qatar, so that these terminals together with those in France, Belgium and the Netherlands can be used to supply all of Europe with gas - including the countries in Eastern Europe, that currently depend on Russian gas even more than we do.
