Isn't storage just exactly the problem? From what I understand every single possible storage tank in Europe is filled to the brim, and most if not all of the LNG ships are already there or en-route.
I wrote the system for National Grid UK LNG storage and trading in the early 2000s. I think they had 6 sites online now. Milford Haven was in progress I believe. Then they gradually started closing them as not required... Same with coal and nuclear plants! LNG is not so easy to store and there were a lot of safety regulations for site visits.
That's always the problem - most obvious in companies but also visible with governments - anything that is for "once in a lifetime emergencies" gets ignored or downsized eventually because it's hard to explain the reasons for the costs.
I was part of the research organisation which owned all of the British Gas R&D work going back into the 70s and beyond. I also maintained the software for all the high pressure gas metering sites and converted some of the code and calculations from Fortran and Basic into more supportable APIs. There was a lot of early work on GIS mapping for pipeline management as well.
I don't think this is correct. According to the coverage I've read, the facility in question is Rough[1] which closed in 2017. Around that time Truss was "Secretary of State for Justice" and "Secretary of State for Environment, Food and Rural Affairs". In case the latter sounds vaguely energy related, there's a separate cabinet post called "Secretary of State for Business, Energy and Industrial Strategy".
