    Carbon dioxide shortage threatens fizzy drink and beer sales

    A shortage of carbon dioxide gas (CO2) across Europe has left drinks manufacturers scrambling to secure supplies, as the continued warm weather in Britain and the World Cup has led to a surge in demand for carbonated drinks.

    While supply tightened as early as April due to planned shutdowns at some ammonia plants for maintenance works, the situation is now critical because other plants have had to close due to technical issues, at a time when they should be ramping up production.

    Not proper beer of course, since the yeast produces all the carbon dioxide that needs!

    I don't understand the connection to ammonia production. I thought CO2 was produced by fractional distillation of air?
  1.  
    +1 on the real ale.

    Industrial CO2 is a byproduct of Hydrogen production , which mostly comes from natural gas Methane. Hydrogen is used for producing ammonia among others.
    CH4 + 2H2O <> CO2 + 4 H2

    Air distillation produces nitrogen, oxygen and some noble gases. There's not (yet!) enough CO2 in the air to easily recover it from air. CO2 freezes up at air distillation temperatures.

    Ironically CO2 is used to preserve packed meat, without CO2 there may be more food waste so more CO2 from food production ..
