Flywheel

In June, I wrote how intermittent power sources such as photovoltaics and wind would have to compete with baseload technologies such as IGCC "Clean Coal" and nuclear for capacity on the grid.  The key problem is that neither baseload technologies nor intermittent technologies are able to match themselves to the fluctuations of demand.  This creates a need for technologies which can fill the varying gaps between supply from these sources, and normal energy use.  From the comments, it seems like I was not completely clear how intermittent and baseload power cause problems for each other, so I will start...

Beacon Power Corp (BCON) announced that it has recently been awarded a United States patent for the unique design and construction of its composite flywheel rim, and that a few days ago, it received a written notification that another U.S. patent on the rim is to be granted in early February 2005. The composite rim is a key component of a flywheel energy storage system, as a rim's mass and ability to spin at high speeds have a direct relationship to the amount of energy that can be stored. Beacon Power, a pioneer in this technology, has been...

7.17.09 Storage Week John Petersen Infocast’s Storage Week was all I had hoped it would be, and more. While I thoroughly enjoyed serving on three discussion panels and was warmly received by roughly 250 attendees, including executives of companies that I've occasionally criticized, the most important value for me came from the opportunity to hear four days of high-level presentations by industry executives, national thought leaders and policymakers who repeatedly stressed that: From a utility perspective grid-based energy storage is the functional equivalent of an instantly...

10.08.09 ACPW John Petersen This morning I awoke to a comment from Seeking Alpha contributor Michael Eisenberg who asked me to lay out my core thesis on why Active Power, Inc. (ACPW) merits attention from investors who are interested in the energy storage sector. While Altenergystocks and Seeking Alpha don't generally like to publish articles about companies that trade for under a dollar, I believe Active Power merits an exception to the general policies. As regular readers know, I've been a small company securities lawyer for almost...

Active Power Inc (ACPW) announced an order from Caterpillar Inc. for eleven one-megawatt flywheel UPS systems. The majority of these systems will be shipped during the current quarter and will be used to provide power protection for a large datacenter in the United States.

Beacon Power Corp (BCON) is scheduled to deliver two presentations at conference sessions next week at the 2nd Annual POWER-GEN Renewable Energy Conference and Exhibition, held at the Las Vegas Hilton from March 1-3. Both presentations will focus on the role of flywheel energy storage systems, and Beacon's patented technology in particular, in critical power grid applications.

In August of last year I wrote an article titled "Grid-based Energy Storage: Birth of a Giant." Over the last 12 months I've written a series of follow-on articles that discuss the principal classes of manufactured energy storage devices and the companies that are making or planning to make products for smart grid energy storage applications. My entire archive of articles on the energy storage sector is available here. One of the biggest problems I've encountered over the last year has been a dearth of reliable third party information that can help investors understand the breadth and...

Active Power Inc (ACPW) announced that the largest airport in Mexico, Aeropuerto Internacional de la Ciudad de Mexico (AICM), has selected its battery-free CleanSource® UPS to protect runway and taxiway lighting. Additionally, a new terminal that will begin construction this year will also be supported by Active Power's battery-free systems. Deliveries against this order started in Q4 of 2005 and will continue through the first half of 2006. Active Power is following a good business model of selling into a niche that it already has a good presence in (FuelCell Energy has a similar practice with Hotels.)...
