“…It is well known that CaO deactivation is caused by significant sintering-induced loss of meso-porosity or pore plugging [26,27]. This arises because the low Tammann temperature (TT) of CaCO3 (~529 °C) is below the typical operating temperature (~850 °C) [28].…”

The reversible CaO/CaCO3 carbonation reaction (CaL) is one of the most promising candidates for high-temperature thermochemical energy storage (TCES) in concentrated solar power plants (CSP). Here, a sacrificial citric acid-based carbon template was developed to produce high-performance CaO-based sorbents to mitigate the progressive deactivation with sequential carbonation-calcination cycling. The carbon template was formed through in situ pyrolysis of citric acid in a simple heating process under nitrogen. After a secondary calcination step in air, a stable porous MgOstabilized nano-CaO powder was generated and achieved high long-term effective conversion due to its resistance to pore plugging and sintering. By dry mixing citric acid with limestone-dolomite mixtures, this procedure can also be applied to synthesize MgO-stabilized CaO pellets via an extrusion-spheronization route, which resulted in comparably stable and effective conversion as the optimized CaO powder. Additionally,

“…Again, in comparison to limestone, the shells presented better carbonation performances and faster decarbonation. Another waste material, carbide slag, was studied and compared to limestone [62]. The measured optimum carbonation temperature range for energy storage using carbide slag carbonated under 1.3 MPa was 800-850 • C, against slightly higher temperature for limestone, 850-900 • C. Under these operating conditions, the carbonation conversion of carbide slag was slower than that of limestone.…”

The exploitation of solar energy, an unlimited and renewable energy resource, is of prime interest to support the replacement of fossil fuels by renewable energy alternatives. Solar energy can be used via concentrated solar power (CSP) combined with thermochemical energy storage (TCES) for the conversion and storage of concentrated solar energy via reversible solid–gas reactions, thus enabling round the clock operation and continuous production. Research is on-going on efficient and economically attractive TCES systems at high temperatures with long-term durability and performance stability. Indeed, the cycling stability with reduced or no loss in capacity over many cycles of heat charge and discharge of the material is pursued. The main thermochemical systems currently investigated are encompassing metal oxide redox pairs (MOx/MOx−1), non-stoichiometric perovskites (ABO3/ABO3−δ), alkaline earth metal carbonates and hydroxides (MCO3/MO, M(OH)2/MO with M = Ca, Sr, Ba). The metal oxides/perovskites can operate in open loop with air as the heat transfer fluid, while carbonates and hydroxides generally require closed loop operation with storage of the fluid (H2O or CO2). Alternative sources of natural components are also attracting interest, such as abundant and low-cost ore minerals or recycling waste. For example, limestone and dolomite are being studied to provide for one of the most promising systems, CaCO3/CaO. Systems based on hydroxides are also progressing, although most of the recent works focused on Ca(OH)2/CaO. Mixed metal oxides and perovskites are also largely developed and attractive materials, thanks to the possible tuning of both their operating temperature and energy storage capacity. The shape of the material and its stabilization are critical to adapt the material for their integration in reactors, such as packed bed and fluidized bed reactors, and assure a smooth transition for commercial use and development. The recent advances in TCES systems since 2016 are reviewed, and their integration in solar processes for continuous operation is particularly emphasized.

Material baku untuk proses Thermochemical Energy Storage (TCES) yang selama ini berasal dari bahan tambang yaitu CaCO3. CaCO3 bisa didapatkan dari cangkang organisme laut. Pada makalah ini bertujuan mengkaji pada temperatur berapa cangkang kerang tiram dapat menghasilkan CaCO3 yang dapat digunakan sebagai bahan baku TCES dan jenis mineral CaCO3. Sampel Cangkang kerang tiram (Crassosstrea gigas) disintering pada suhu 600C, 700C, 800C, selama 5 jam menggunakan Furnace. Produk sintering kemudian dikarakterisasi dengan X-Ray Diffraction (XRD). Hasil penelitian menunjukkan terjadinya peningkatan suhu sintering akan menguraikan senyawa CaCO3. Cangkang kerang tiram yang dapat menghasilkan CaCO3 tampa adanya senyawa lain yaitu cangkang kerang tiram yang dikalsinasi pada temperatur 600C. Hasil penelitian ini menyimpulkan bahwa cangkang kerang tiram yang dikalsinasi pada suhu 600C berpotensi sebagai material baku TCES.
