Robot train in Nevada will generate energy like a Prius

Advanced Rail Energy Storage

An innovative system in Nevada for generating energy on demand to stabilize the grid when needed will use the railroad equivalent of pumped hydro, which uses excess renewable energy top pump water uphill into a reservoir, where it is released…

Cooled liquid energy storage is economically viable

Energy can be stored many ways, the most common being in batteries. Concentrated Solar Power projects store excess heat from the sun in molten salt to power turbines at night. Pumped hydro uses excess energy to pump water uphill into…
