Great Britain has only two days of fossil gas stored after a decline in energy reserves, as more tankers carrying liquefied natural gas (LNG) are diverted from their course to Europe towards Asia because of the Iran war.
Great Britain had 6,999 gigawatt hours (GWh) of fossil gas stored on Saturday, according to figures from National Gas, which owns and operates the gas national transmission system. This compares with 9,105 GWh a year earlier.
Maximum capacity is 12 days of gas, and current storage levels equate to under two days of reserves, leading to concerns that Great Britain could run out of gas if the crisis in the Middle East escalates further.



Gas is hard to store so reserves are small. Times like this with price increases and warmer weather is exactly when you lower reserves to create temporary supply to depress price inflation. When prices are better, or as winter approaches, you buy extra to fill the reserves back up.
