Thermochemical energy storage using calcium looping. Calcium looping is a chemical process that could be used to store energy, in the form of calcium oxide where CO 2 is also generated, obtained from the calcination process of the calcium carbonate. This reaction is reversible, which allows for the looping process.

By using calcium carbonate powder of particle size ∼ 10 nm (and therefore of high surface area) it has been shown that the reaction CaCO3 ⇄ CaO + CO2 can be made almost wholly reversible. A reactivity of 93% was achieved, (i.e. 93% of the calcium oxide reacted with carbon dioxide) and this was maintained for 30 24-h decomposition-back reaction cycles …

Calcium and Mg influence soil aggregation and soil structure, thus affecting soil health. The Ca 2+ ion is smaller than Mg 2+ hence it is more efficient in binding soil particles, and has more flocculating power (the ability to facilitate the formation of small masses) than Mg. Conversely, Mg could lower soil structural stability.
