Gasometers are an example of industrial history, which are slowly being decommissioned changing our skyline forever.
But exactly what is (or was) a Gasometer (or Gas holder as it's also known)? it is a large metal tank where gas was stored before being distributed through pipes to consumers. Gas holders were originally used for balancing the daily demand of manufactured gaseous fuels.
With the move to natural gas and creation of the national grid network, their use has steadily declined as the pipe network can store gas under pressure, and has been able to satisfy peak demand directly. This deemed the use of gasometers redundant.
