There's real long-duration energy storage now. Can it find a market?
We need very large (multi-gigawatt-hour) storage for big cities and megacities, but so far the only viable option to serve them is pumped hydro storage (PHS): it uses cheaper nighttime electricity to pump water from a low-lying reservoir to high-lying storage, and its discharge provides instantly available generation.[76] With renewably generated e

In large, populous nations, the complete reliance on these renewables would require what we are still missing: either mass-scale, long-term (days to weeks) electricity storage that would back up intermittent electricity generation, or extensive grids of high-voltage lines to transmit electricity across time zones and from sunny and windy regions to

- By bringing demand more under grid operators’ control, DERs virtually eliminate curtailment, or discarding of renewable energy due to temporary oversupply, through 2045. Just as they allow transmission to be used more effectively, they allow us to consume more of the energy generated by existing utility-scale renewables.

- Rooftop solar, battery storage, electric vehicles, and energy management devices are all examples of DERs – numerous pockets of energy spread throughout the grid rather than concentrated in a single spot. Unlike centralized sources of power, DERs can make the grid flexible and enable control of both electricity supply and demand in real-time. Howev... See more

- This is where Professor Jeff Dahn Of Dalhousie University comes in. He and his team partnered up with Tesla in 2016 to create the Tesla Advanced Battery Research division. Their primary goal is to make batteries last longer, they also aim to increase energy density and decrease costs. Prof Dahn recently published a study showing the world the fruit... See more

- Importantly, DER deployment is rapidly increasing – according to Wood Mackenzie’s second annual U.S. DER Outlook, we’re expected to reach 253 GW of DER capacity and demand flexibility potential by 2026. The sheer mass of behind-the-meter renewable energy coming online will fundamentally alter the nature of our electricity supply.

affordable batteries that could store enough energy for a city—what we call grid-scale batteries, as opposed to the smaller ones that run a phone or computer—and hold it long enough to get through seasonal intermittency. One inventor I admire is working on a battery that uses liquid metals instead of the solid metals employed in traditional batteri
