"If it can be scaled up, the technology can help solve an important issue — the storing of renewable energy.""If it can be scaled up, the technology can help solve an important issue — the storing of renewable energy."Researchers at MIT have come up with a new way to store energy inside a modified concrete, a tantalizing potential solution to the looming energy storage problem.
Stefaniuk and his team believe their novel material could be a game-changer, taking the pressure off the electrical grid by providing ways to store green energy, the generation of which can fluctuate greatly throughout the day. More intriguingly, the cement could be used as a building material — to "have walls, or foundations, or columns, that are active not only in supporting a structure, but also in that energy is stored inside them," Stefaniuk told theHowever, the tech is still in its infancy. For the time being, their proof-of-concept supercapacitor can only store enough energy to power a 10-watt LED for 30 hours.
