Ambri’s Better Grid Battery
If Ambri or anyone else can make grid storage cheap and dependable, it will change the way we get electricity. Because the output of wind and solar farms is intermittent, these renewable sources alone can’t reliably power the entire grid, or even most of it. Grid operators need to ensure a steady balance between the power being consumed and the amount being generated. The system must be able to meet peak demand, which typically occurs when people turn on their air conditioning on hot summer days. That means wind and solar farms are typically backed up with natural-gas plants that can quickly add to the electricity supply.
