As global energy demand accelerates, one truth remains underappreciated: heat is the largest end use of energy. Today, more than 50 percent of global final energy consumption is dedicated to ...

Finland is turning one of the planet’s most ordinary materials into a high impact climate tool, using hot sand to store vast amounts of energy and release it as heat when homes and factories need it ...

Finland is harnessing the unexpected power of sand to decarbonise industrial heat – a major “blind spot” in global emissions. Industrial heat production is one of the largest and hardest-to-solve ...

Energy from renewable sources can be stored in a sand heat storage system. A system with circulating sand is said to be particularly effective. Finnish start-up The Storage has installed a heat ...

A research group from Ghana has developed a solar PV-powered steam cooker (ISESC) with sand-based thermal energy storage (TES). “The potential of sand, given its thermal stability and low cost, has ...

Researchers from China have proposed to combine solar-air source heat pumps (SASHP) with sand-based thermal floor storage in rural clean heating renovation projects. “In rural areas where economic ...

The systems, which can store clean energy as heat, were chosen by readers as the 11th Breakthrough Technology of 2024. We need heat to make everything from steel bars to ketchup packets. Today, a ...
