Some figures on UK gas storage

mapj1

For natural gas to allow data sources to be compared, assuming reasonably pure methane

1 GWh  ≈0.1 MScm 

UK daily burn  is ~ between 100 and 200MSCM, or  1000-2000GWh each day. 

UK gas storage as a few graphs   Note that our long range store has a leak and is not available, so why they plot a flat line who knows, Scroll a bit for the medium range store, and realise we have about 15 000 gigawatt hours in the tank (7 to 15 days if there was no incoming supply at all - but there always is..)

Then scroll down to the LNG graphs, and notice that the up steps are when a ship unloads LNG at Milford haven or wheever, and the steady decline between those up ticks is our rate of use from those tanks, perhaps 2000 gigawatt hours in 3- 4 weeks.  That has about 6000 GWhr in it tonight.  But many of us in the south have not put the heating on yet ;-) so that rate of run-down could probably rise a bit.

    For some time, my now late Father-in-Law was the Master on either of Shell's gas carriers, the Methane Princess and Methane Progress, which used to transport liquid methane from Arzew in Algeria to the British Gas facility at Canvey Island on the River Thames.  The main storage at the time - mid 70's - was a large hole in the ground which had a metal lid over it.  The theory was that the liquid methane would initially freeze the ground and thus form its own storage tank.  

    When visiting I often wondered how far the methane escaped through the ground, since there were bungalows/houses built right up to the site perimeter fence.

    The other thing that got my attention was the warning sign near the fire control station on the ship's bridge, this advised that should the vent stacks from the ship's methane tanks ignite, perhaps due to lightning, DO NOT sound the Fire Alarm, but instead blow the flame out by injecting nitrogen into the stack.  What the Fire Alarm was to be sounded for was not stated….

    The website linked to does not appear to be working correctly, observe for example the wild variations in predicted demand and predicted temperatures for the next few months.

    Yes, the Nat Grid ability to predict the future is not very confidence inspiring is it ?  Perhaps this explains some recent  ministerial statements, that are about as reassuring as Corporal Jones in dad's army - “ don't panic, don't panic”.

    I presume it is an artifact of some join the dots curve fitting software running off the end of the real data.
