1. A system for the preparation of carbon-neutral carbonated beverages utilizing carbon-neutral carbon dioxide, comprising:
a storage vessel of pressurized, purified carbon dioxide, where the carbon dioxide was captured from a gas supply comprising a mixture of gases selected from the group consisting of ambient air and a mixture of a major proportion of ambient air with a minor proportion of flue gas effluent, and is stored at a pressure of at least about 120 psi; a source of flowing potable aqueous liquid at a lower pressure than the storage vessel of carbon dioxide; a carbonator vessel in fluid flow connection with the source of flowing aqueous liquid and the storage vessel of pressurized, purified carbon dioxide, the fluid flow connections being controlled by suitable regulating valves to set the pressure in the carbonator dependent upon the temperature of the potable water; and dispensing means for passing carbonated liquid from the carbonator to a container for immediate consumption or to a sealed container for storage and subsequent use; the carbon dioxide being obtained from at least a major proportion of ambient air by a process comprising providing energy to a primary production process with generated waste process heat; heat exchanging waste process heat from said primary process with water to co-generate substantially saturated steam; alternatively, repeatedly exposing a CO2-sorbent to a mixture of gases selected from the group consisting of ambient air and a mixture of a major proportion of ambient air and a minor proportion of flue gas effluent, and process heat steam, in capture and regeneration system phases, respectively, so as to adsorb carbon dioxide from the gas mixture during said capture phase, and to regenerate the sorbent and capture purified carbon dioxide from ambient air during the regeneration phase; and compressing the purified, captured carbon dioxide, for storage, at least to the desired pressure for use in carbonation of potable aqueous liquids; thereby enabling the preparation of carbon-neutral, carbonated water. |
