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.

Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

Wind and solar parks produce a large portion of their energy. Then, as now, wind farms are operating off the world’s coasts—but not all of these offshore sites are connected to the mainland via underwater power cables. Some of the wind farms instead sit in clusters more than 100 kilometers out at sea.
