Gasometers - common outdoor sights
in the first half of the 20th century

Working, gasometer expanded with coal gas from a gasworks, England, in the first part of the 20th century.

Medium-sized working, gasometer expanded with coal gas from a gasworks, England, in the first part of the 20th century. Such photos are rare - unlike those of the demolished shells such as the one lower down the page - and I am grateful to John Cronin of the Hoylake Junction website for permission to reproduce it.

When I was growing up in the 1940s and 50s it was common on any journey to be confronted by a huge cylindrical edifice looming up out of the distance. It was so massive that anyone born after 1960 would - if it were possible for them to see it - be forgiven for thinking that aliens had landed! It was called a 'gasometer', pronounced with the stress on the 'om' (like in 'Tom'). There were lots of gasometers around. They stored gas - actually 'coal gas', see the insert below.

Gasometers, coal gas and gas works

A gasometer was a cylindrical metal storage tank for gas located at what was called a 'gasworks' - a factory to produce gas from coal. All London gasworks had to be near a railway line as the coal had to be transported from the northern coal mines.

I was taken on a school trip to the local gasworks at the bottom of Angel Road Edmonton. I must have been about 12 years of age at the time. Because the gas works burnt coal to release the gas, the result was known as 'coal gas' or 'town gas'. It could not be produced on demand, so had to be stored to meet the demand at peak times. Hence the need for gasometers.

The massive metal storage tank of the gasometer had smaller cylindrical tanks fitted inside, rather like the sections of a telescope. As the gas was pumped in, these tanks expanded, rising into the sky and rotating slightly in the process. Rubber gaskets sealed the sections.

With demand for gas during the day, mainly from industry, the gasometer visibly slowly decreased in height. At night the main usage was for street lights. Before electric lights gas was also used for lighting in homes, pubs and theatres. Some houses had gas fires, but coal fires were the norm.

Most districts had gasworks. They never stopped production, 24 hours a day 7 days a week.

Gasometers must have been the largest metal structures ever erected in any town or city. Only a picture can give a indication of their massive size.

A gasometer catches light

During a German air raid in World War Two, a bomb went through the top of one of the gasometers in the gasworks along Angel Road, Edmonton, about a mile due east of us. As you can imagine, the flames shot several hundreds of feet up into the air. Quite a sight!

My mother mentioned nothing about gasometers in her written recollections of her childhood in the early 1900s, but they must have existed because records date some of them to the late 1800s. They certainly featured in my own childhood in Edgware, north London where the local gasometer was close to Canons Park Tube station, at the cross-roads of Whitchurch Lane, Marsh Lane, Honeypot Lane and Wemborough Road, in what are now the grounds of Whitchurch Middle School.

Natural gas, North Sea gas and the demise of gasometers

In the early 1960s 'natural gas', also known as 'North Sea gas', replaced coal gas. So gasometers and their associated gas works became redundant. Over time they were largely taken down and sold for scrap. The shells of a few remain, like one in Camberley which I photographed recently and which was small for its type. The metal struts give some idea of how large it must have been when it was inflated. Much larger gasometers, though, were common sights.

If you can add anything to this page or provide a photo, I would be pleased to hear from you.

One of the widely publicised advantages of natural gas was that it wasn't poisonous like coal gas - although of course incomplete combustion did produce the poisonous carbon monoxide. Before the advent of natural gas 'putting one's head in the gas oven' (without lighting the gas) seemed to be the most common suicide method.

Many of the household appliances using coal gas had to be converted to use natural gas. Many a family in our street complained that the oven conversions didn't work properly and they were supplied with new ovens free. That wasn't in my mother's nature, and she always complained that her oven didn't work as well after conversion.
