Assessment of four main representative flint facies as alternative storage materials for concentrated solar power plants

Exploration of Basalt Glasses as High-Temperature Sensible Heat Storage Materials

“…Figure displays the contour picture of basalt glasses at a high temperature, showing that the volume hardly changes with increasing temperature without being subjected to an external force. The linear thermal expansion coefficients of the three samples vary between 7.63 and 8.91 × 10 –6 °C –1 , which are significantly lower than that of flint (16–18 × 10 –6 °C –1 ), Egypt and France basalts (10 × 10 –6 °C –1 ), high-temperature concrete (9.3 × 10 –6 °C –1 ), and castable ceramic (11.8 × 10 –6 °C –1 ), indicating that basalt glasses possess good thermal shock resistance and are suitable candidates for heat storage materials. The thermal expansion coefficients of the studied basalt glasses are slightly different, and the value of BG-1 is relatively low, which also confirms that the network structure of BG-1 is more stable.…”

“…In 200–800 °C, due to the decomposition reaction of silanol, new Si–O–Si bonds and water molecules are produced. 37 Water molecules are encapsulated in the closed pores of the network skeleton, the vapor pressure increases with increasing temperature, and the stress causes the internal atomic bonds to break, which then leads to the occurrence of cracks. 18 The ores can be regarded as polycrystals composed of various mineral phases.…”

“…Below 200 °C, the mass loss is attributed to the escape of the adsorbed water, and sample B-2 has a higher adsorbed water content of about 1.7%. In 200–800 °C, due to the decomposition reaction of silanol, new Si–O–Si bonds and water molecules are produced . Water molecules are encapsulated in the closed pores of the network skeleton, the vapor pressure increases with increasing temperature, and the stress causes the internal atomic bonds to break, which then leads to the occurrence of cracks .…”

Benchmarking study of demolition wastes with different waste materials as sensible thermal energy storage

“…Silicon oxide content in storage material is a characteristic property to define material's strength and hardness. Higher amount of silicon oxide avoids crushing during thermal cycling under repeated thermo-mechanical stress [43].…”

Assessing the influence of thermal energy storage on the performance of concentrating solar power plant

“…The progressive global trend in CSP generation is shown between 2009 and 2018, while the Indian scenario of CSP generation is shown between 2011 and 2018 as per IRENA 2019 reports. With many new projects under‐ construction and development, it is sure that CSP with thermal energy storage (TES) is a stiff competitor to fossil fuel‐based power generation units 8‐14 …”
