... Abstract Thermochemical energy storage is promising for building applications as it offers high energy density and near-lossless storage. For example, inorganic salt hydrates that undergo reversible solid-gas thermochemical reactions can be used for thermal load shifting and/or shedding...

... Abstract Among the available energy storage technologies, pumped thermal energy storage (PTES) is emerging as a potential solution for large-scale electrical energy storage with no geographical limitations and high roundtrip efficiencies. However, PTES requires a low-cost high temperature heat...

... with different working fluids and a subcritical Rankine cycle operating with ammonia are compared. Liquid thermal energy storage systems are used. For the Brayton cycle, also packed bed storage systems are considered as an alternative. A new cost correlation for turbomachines, initially developed for organic...

... Abstract The present work investigates using a molding technique to fabricate stable salt structures for thermochemical energy storage. Two type of salts were investigated: pure MgSO 4 and a blend of 53% CaCl 2 with 47% MgSO 4 . These salts were mixed with two common binders and hot pressed...
