Based on this premises, the present work discusses the use of iron ores for long-term energy storage on the example of siderite, a natural iron carbonate ore which was identified as suitable material.. Based on this premises, the present work discusses the use of iron ores for long-term energy storage on the example of siderite, a natural iron carbonate ore which was identified as suitable material.. Despite its maturity and acceptable performance, molten salt energy storage presents several drawbacks, related to corrosiveness, limitation of the maximum working temperature to avoid salt degradation (which limits the efficiency of the power cycle), limitation of the minimum working temperature. . Renewable energy requires cost effective and reliable storage to compete with fossil fuels. This study introduces a new reactive carbonate composite (RCC) where Fe 2 O 3 is used to thermodynamically destabilise BaCO 3 and reduce its decomposition temperature from 1400 °C to 850 °C, which is more.

Iron carbonate, traditionally used in providing animals with an excellent source of iron nutrition, has several other uses. Today, it is utilized in many applications.
Thermochemical energy storage (TCS) systems are receiving increasing research interest as a potential alternative to molten salts in concentrating solar power (CSP) plants. In this framework, alkal...
Therefore, their reversible calcination/carbonation reaction with CO 2 can be used to store/release energy in CSP plants. However, in spite of these promising features, the TCS research field is relatively new, and most of it is still limited to the lab-scale.
