Researchers in China have 3D-printed a cement-based supercapacitor that stores electricity while retaining compressive strength comparable to concrete used in slabs and stairs, lighting LEDs and other small devices. The scaling, durability and cold-weather limits are being tested.

Hormigón impreso en 3D almacena electricidad y soporta carga

ZME SCIENCE

Investigadores en China imprimieron en 3D un supercondensador a base de cemento que almacena electricidad y mantiene una resistencia a la compresión comparable a la del hormigón utilizado en losas y escaleras. El prototipo alimentó a luces LED. Ahora toca resolver la escala, la durabilidad y resistencia al frío.

A Portuguese study has modelled how surplus wind and solar power could be stored as compressed air in deep porous rock. In the most favorable scenario, one reservoir could hold up to 1 TWh, close to the consumption of some medium-sized cities.

Italy will require all of its estimated 12,000 paid beach concessions to be publicly tendered by September 30, 2027, ending automatic renewals that kept many operators in place for generations. The reform responds to EU competition rules and could improve transparency over access to public coastline, though family firms fear larger bidders.
