When modern-age electric vehicles first became “a thing” about 10 years ago, supercapacitors were a frequent topic of discussion, due to their value in delivering large amounts of power—far more energy per unit than batteries could provide. As it turns …

Energy Storage Is Changing the Entire Energy/Transportation Landscape
Here’s a story about two very progressive companies dealing with 21st Century energy: Tesla and Sierra Nevada (a top-notch beer brewery). The essence is that Tesla has installed a fairly large battery storage system, apparently to lower energy costs for …

Making Batteries from Carbon Dioxide: An Idea That Will Almost Certainly Never Come To Fruition
Here’s another example of a phenomenon so plentiful in cleantech: it’s doable, but there are no economic reasons that it will ever be done. It’s a battery system that is built by taking carbon dioxide, perhaps from a point source …
Cool New Idea in Wind Turbines
Here’s a new idea in the quest to reduce or remove the variability of wind energy: an integrated water reservoir, making use of the huge watertight tower. This creates a (small) pumped hydro energy storage solution without the elevation change. …
Breakthrough in Energy Storage from the University of Wisconsin
Here’s an exciting development that lies squarely on the intersection of the main problems we face in making the migration from fossil fuels to renewable energy. Combining solar energy with storage, it’s a device that converts incoming solar energy directly …

The Energy Storage Problem
2GreenEnergy megasupporter Cameron Atwood just sent me this from G.K. Surya Prakash (pictured), a chemistry professor at the University of Southern California: “Earth doesn’t have an energy problem. We have an energy storage problem.” There is no doubt that the advent …

This Report on Flow Batteries Will Make You Smile
A reader from the Unitarian Universalist Church of Palo Alto, CA, a group that’s heavily committed to sustainability, writes: For an emotional uplift check out the flow battery progress sponsored by ARPA-E (Advanced Research Projects Administration-Energy).
How Abundant Is Lithium?
A reader asks, “Has it been determined whether the world’s supply of lithium is sufficient to produce enough battery capacity to make renewables reliable?” It’s a complicated question, unfortunately. Perhaps it’s best summed up by what the CEO of a …
U.S. Federal Government Takes Several Meaningful Steps in Forwarding the Cause of Energy Storage
Advocates of renewable energy who may be interested in understanding the Obama Administration’s approach to energy storage should check out this recent “fact sheet.” You’re bound to be impressed that our government’s involvement here is extremely wide-ranging and robust. …
New Concept in Energy Storage
A huge percentage of the power grid was built solely to address peak loads, and is used less than 100 hours per year. This is one of the many reasons that energy storage in any of its forms is so …
