How Giant Concrete Spheres on the Seafloor Could Store Renewable Energy

Material & Energy, Renewable Energy, Tech /

To avoid using large areas of land for building renewable energy storage facilities, the Fraunhofer Institute has been developing a bold yet feasible idea: using hollow concrete spheres submerged in the deep ocean to store energy. The StEnSea Project: Storing Energy in the Sea Since 2011, the StEnSea (Stored Energy in the Sea) project has […]

Abandoned Mines May Be Repurposed as Gravity-Powered Batteries

Renewable Energy /

A gravity battery generates electricity by releasing a heavy load, converting potential energy into power when grid demand is high. When surplus energy is available, the system lifts the load back up for future use. A common example is pumped-storage hydroelectric systems, where water flows downhill to generate power and is pumped back up when

Guiding Electricity Through the Air Using Ultrasound Pulses

Material & Energy, Renewable Energy, Tech /

Electricity is naturally unpredictable, typically requiring wires and circuits for control. However, researchers in Europe and Canada have successfully directed sparks through open air and around obstacles using ultrasound waves. In open air, electricity naturally spreads in unpredictable directions—much like a lightning bolt. Its path is influenced by slight variations in air density, charge distribution,
