Generating and storing sustainable energy is the holy grail

Transmission lines have fallout. Battery farms are expensive. Repeating Snowy II is out of the question.  But there is a simple solution to generating and storing sustainable energy for overnight electricity. And country businesses are taking it on themselves to prove its powerful potential. The Vast Solar Concentrated Solar Thermal storage and power generation plant …

Elevating the Potential of Concentrated Solar Power Heat Storage in Australia

The future of sustainable energy in Australia lies in finding cost-effective solutions to generate and store electricity overnight. The need for reliable energy sources in rural areas and the impending retirement of coal-fired power stations create an urgent demand for alternatives. While wind farms and lithium-ion batteries have their limitations, solar thermal heat storage is …

Direct contact cascaded immiscible inorganic salt/high-density polyethylene

The present work assesses the direct contact cascaded immiscible phase change material (PCM) for solar heat storage systems (SHSS) in water heating applications. The direct contact cascaded immiscible PCM uses ternary salt mixture (TSM) and high-density polyethylene (HDPE). Improvement on phase behavior and thermal properties are obtained for the direct contact cascaded immiscible TSM/HDPE. The …

Successful PROMES-CNRS thermocline test of latent/sensible heat storage

Most industries currently burn fossil fuels for heat. But to supply heat directly from sunlight, research attention is turning to solar thermal energy storage (TES) so that heat can be delivered as consistently as combusting a fossil fuel using purely solar energy. A solar thermal energy storage breakthrough – a novel combination of latent and …

Preparation and thermal property characterization of NaCl–Na2CO3–Na2SO4 eutectic salt mixed with carbon nanomaterials for heat storage

Coupling with supercritical power cycle can improve the thermal efficiency of the concentrated solar system. Design the suitable thermal storage medium is critical to the new coupling system. A new ternary eutectic salt with low cost was developed composed of NaCl, Na2CO3, and Na2SO4 based on the calculation method of phase diagram, meeting the requirements of …
