IIASA-led study proposes Underground Gravity Energy Storage as long-term energy storage solution for renewables

Green Car Congress

However, because sunshine and wind are inherently variable and inconsistent, finding ways to store energy in an accessible and efficient way is crucial. While there are many effective solutions for daily energy storage, the most common being batteries, a cost-effective long-term solution is still lacking. Dabek, P.B.,

Researchers use quantum computing method to optimize molecular photoswitches for solar energy harvesting

Green Car Congress

Molecular photoswitches that can both convert and store energy could be used to make solar energy harvesting more efficient. The procedure was based on a dataset of more than 400,000 molecules, which the researchers screened to find the optimum molecular structure for solar energy storage materials.
