context_page_description: A gas holder, or gasometer, is a large container in which natural gas or town gas is stored near atmospheric pressure at ambient temperatures. The volume of the container follows the quantity of stored gas, with pressure coming from the weight of a movable cap. Typical volumes for large gas holders are about 50,000 cubic metres, with 60 metres diameter structures.
  Gas holders now tend to be used for balancing purposes, to ensure gas pipes can be operated within a safe range of pressures, rather than for actually storing gas for later use.
