Idle Oil Wells’ Next Act? Becoming Batteries for Renewable Energy

By Coco Liu

The fan club for abandoned oil and gas wells is an exceedingly small one, but Kemp Gregory might just be the president. Where others see an eyesore or a source of rogue methane emissions, Gregory sees opportunity.


What’s going on with hydropower?

For decades, hydropower has been most common source of renewable electricity in the world. (In the US, it was passed by wind a few years ago.) Pumped hydro — large hydropower facilities in which water is pumped up and run down hill to store energy — remains the most common form of energy storage, both in the US and in the world.

By Yan Wang

Battery recycling has become an important issue in the United States, and recent efforts by the federal government, private industry and academia suggest that the country is quickly making batteries more easily recycled, reused and kept out of landfills.


These companies want to go beyond batteries to store energy

By Casey Crownhart

If y’all have been around for a while, you know that I love writing about batteries (see exhibits A, B, and C). Using chemical reactions to store energy is handy and scaleable, and there are about a million ways to do it, which is why batteries have basically become synonymous with energy storage.
