HC Deb 25 January 1974 vol 867 cc367-8W
Mr. Roderick

asked the Minister for Energy whether liquid natural gas storage tanks are intended in South Wales for any reasons other than emergencies.

Mr. Emery

Yes. In addition to providing security of supply, the LNG storage is required for meeting peak demands for gas, thereby enabling more gas to be supplied in South Wales during the remainder of the year.

Mr. Roderick

asked the Minister for Energy what storage capacity for liquid natural gas he estimates is needed in South Wales ; how many tanks are needed ; and how many days' supply this represents.

Mr. Emery

The British Gas Corporation estimate that it requires one storage tank of 20,000 tons liquid capacity now, to be followed by a second of similar size later on. The two tanks would store gas representing about eight days' supply in South Wales at peak demand.

Mr. Roderick

asked the Minister for Energy what is the range of sizes of tanks built in Great Britain to store liquid natural gas.

Mr. Emery

Sizes range from 4,000 tons liquid capacity to 20,000 tons liquid capacity.

Mr. Roderick

asked the Minister for Energy what objections have been received to proposals for establishing storage tanks for liquid natural gas on more than one site in South Wales.

Mr. Emery

24 sites were examined in detail, taking into account their location, ground conditions, economics, and their proximity to mining operations, other property, and the existing gas pipeline. Hirwaun was selected as by far the most suitable, and is the only one at which it is proposed to establish liquid natural gas storage in South Wales.
