More than 90% of the energy storage in the United States today is pumped hydro, using surplus energy to pump water uphill, and harvesting that energy by releasing the water to flow downhill through a turbine. There are several variations …

Hydrogen-Powered Cities?
Here’s an article that claims: South Korea wants to build three hydrogen-powered cities by 2022. Though this might sound legitimate on the surface, we need to realize that hydrogen is a carrier, not a source, of electricity. This, therefore, is …
Wind Energy with Compressed Air Energy Storage: An Update
A few weeks ago I wrote about an investment opportunity in the form of a project deploying wind energy integrated with compressed air energy storage (CAES), and mentioned some good news: a large investor group has offered $40 million in …

New Energy Storage Concept
Here’s a concept that’s one more variation on the theme of doing work against gravity to store potential energy from intermittent sources, to be delivered as needed. It employs automated cranes that pick up bricks and move them sideways, as …
Wind Energy with Compressed Air Energy Storage
Readers may recall discussion of an investment opportunity in the form of a project deploying wind energy integrated with compressed air energy storage (CAES); we’ve been working on it for some time now. Good news: a large investor group has …
Los Angeles Burb Says No to Natural Gas, Yes to Renewables and Energy Storage–Saves a Cool $125 Million
Southern California’s City of Glendale, just northeast of downtown Los Angeles, has scrapped plans for a $500 million 262 MW gas peaker plant in lieu of an array of clean energy alternatives that include battery energy storage that when implemented, this integrated …

Compressed Air Energy Storage
It’s good to see that Compressed Air Energy Storage (CAES) is still in the news. Though it’s been around for decades, it hasn’t enjoyed successful commercialization, but perhaps that’s about to change.

Gravity-Based Energy Storage
About a decade ago, a client hired me to evaluate a start-up in the energy storage field called Advance Rail Energy Storage (ARES). The concept is a variation on the theme of pumped hydro, which currently represents more than 95% …
