In a process for storing liquid rich in carbon dioxide in solid form and subsequently releasing liquid containing mainly carbon dioxide, a solid (13) containing mainly carbon dioxide is formed from at least part of the liquid (1) with or without using indirect heat exchange means, storing the solid containing mainly carbon dioxide,the process steps including subsequently causing at least part of the solid containing mainly carbon dioxide to melt forming a liquid containing mainly carbon dioxide, by direct contact with an auxiliary gas (11) rich in carbon dioxide, wherein the auxiliary gas is at least partially liquefied to form liquid containing mainly carbon dioxide by heat exchange with the melting solid and removing at least part of the liquid (7) containing mainly carbon dioxide. |
