Abstract

L'invention se rapporte à l’utilisation de phosphogypse pour le stockage d’énergie thermochimique, dans laquelle l’absorption d’énergie thermique proprement dite s’effectue par déshydratation du phosphogypse selon les réactions ????????4.2??2?? +?????? ?????????4. 0.5??2?? + 1.5 ??2?? ????????4. 0.5??2??+?????? ?????????4 + 0.5 ??2??.La libération d’énergie thermique s’effectue par réhydratation du phosphogypse initialement déshydraté. Ces réactions sont réversibles.The invention relates to the use of phosphogypsum for thermochemical energy storage, in which the absorption of thermal energy itself takes place by dehydration of the phosphogypsum according to the reactions ????????4.2? ?2?? +?????? ?????????4. 0.5??2?? + 1.5 ??2?? ???????4. 0.5??2??+?????? ?????????4 + 0.5 ??2??.The release of thermal energy is carried out by rehydration of the initially dehydrated phosphogypsum. These reactions are reversible.
