A deal to avert another carbon dioxide crisis in the UK food and drink industry has been extended until early 2022.
US firm CF Industries, a key CO2 producer in the UK, has agreed to continue supplies of the gas.
It said that should give the government and firms time to find other sources of CO2, used in fizzy drinks and for keeping food fresh, as well as to stun pigs and chickens before slaughter.
Firms will now have to pay more for their CO2, but it is unclear how much.
Last month, the government stepped in to subsidise one of the firm's plants after its shutdown due to high gas prices threatened food supplies.
