Concept in Energy Storage Features New Idea, Old Technology
Here’s a novel concept in energy storage: a wind turbine integrated with its own mass that can be moved against gravity to generate and store potential energy which is then converted via a generator to electricity when required. It’s akin …

Concept in Energy Storage
A fellow in Sudan wrote to ask me about energy storage by compressing a large spring, pointing out, quite correctly, that the force associated with compressing a spring is a function of the distance over which the force is applied, …
Achieving Economies of Scale with Clean Energy Concepts
My colleague Aedan Kernan helped us out with many different writing projects in the old days of 2GreenEnergy, though I thought we had lost touch with one another. But in response to my piece on inductive EV charging and other …

Integrating More Solar and Wind Will Eventually Require Large-Scale Energy Storage Solutions
Guest blogger Cameron Atwood sent me this graph showing the increase in the use of solar and wind energy from 2005 to 2012. Impressive stuff. Here in the U.S., our grid-mix is currently comprised of more than 4% wind and …
Utility-Scale Energy Storage
Energy giant Alstom has nailed down a 120 million Euro contract to build a pumped hydro energy storage (PHES) plant in Israel. Currently, there is 129 gigawatts of this technology installed around the globe, and, as we sit here today, …
New Compressed Air Energy Storage Plant Coming to California
It appears that planet Earth is on its way to its third implementation of CAES (compressed air energy storage) – one of a handful of different technologies that warehouses off-peak energy production and makes it available for times of greater …

Obama, Power Plant Emissions, and Renewable Energy
As noted in this article from SmartGridNews, any plan to limit power plant emissions is a plan that will offer a boost to renewables – and, by extension, the value of all solid clean energy investment opportunities. Yes, the process by …

Materials for a Sustainable Energy Future
I try to attend the annual University of California at Santa Barbara Summit on Energy Efficiency, now in its 4th year. This year’s meeting will focus on “Materials for a Sustainable Energy Future.” I plan to “join the Institute for Energy …
Advanced Energy Storage Solutions Will Help Displace Coal-Fired Power Plants
In prepping for the upcoming webinar on ARES (Advanced Rail Energy Storage), I’m recommending that the company position itself more aggressively around the integration of renewables into the grid-mix and, in particular, the imperative to displace coal immediately. As I …
