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...

John Petersen The most widely misunderstood subject in the field of energy storage is the potential for grid-based applications. They fire the imagination because the grid is so pervasive and the need is so great. They also present immense challenges to storage technology developers because the fundamental economic value per unit of grid-based energy storage is very low. While the subject of grid-based storage provides rich fodder for media reports and political posturing, the reality bears little relation to the perception. On March 9th, Lux Research published a sorely needed reality check in a new report titled "Grid...

Beacon Power Corp (BCON) announced that it has executed a contract with the California Energy Commission to demonstrate an advanced energy storage solution for frequency regulation and grid stability. At a business meeting on December 1, 2004, the California Energy Commission had given its approval to the project, leading to contract negotiations that have now been finalized. The contract is expected to produce approximately $1.2 million of revenue, with the majority of it in 2005.

America’s electric power grid is subject to immense inefficiencies that arise from the interplay between centralized power generation, local power consumption and on demand utility service. To put things into a broad perspective, the nameplate capacity of U.S. generating facilities is about 1 million Megawatts (MW), so if all of our power plants ran 24/7 we would have a theoretical annual generating capacity of 8.7 billion Megawatt-hours (MWh). Since demand for electricity fluctuates on both a daily and seasonal basis, total electric power generation in 2007 was only 4.2 billion MWh, or less than 50% of nameplate...

Active Power Inc (ACPW) announced an order from Eaton Powerware for twelve 500 kW DC flywheel systems. These units will ship in the first half of 2006 and be used to upgrade the power infrastructure of an existing data center in the United States.

Electricity storage stocks are publicly traded companies whose business involves the storage of electricity.  They include battery stocks and hydrogen stocks (see links), while companies involved in other storage technologies such as pumped hydro energy storage, Compressed Air Energy Storage, capacitors, flywheels, and thermal storage are listed here. This list was last updated on 3/22/2022. Dais Analytic Corp. (DLYT) Dresser-Rand Group (DRC) Fluence Energy, Inc. (FLNC) Graftech International (GTI) Highpower International (HPJ) Kemet Corp. (KEM) Maxwell Technologies Inc (MXWL) If you know of any energy storage stock that is not listed here and should be, please let us know by leaving a comment. Also for stocks in the...

Beacon Power Corp (BCON) announced that on November 17 it received a letter dated November 16, 2004 from the Nasdaq Stock Market, stating that the Nasdaq Listing Qualifications Panel has granted the Company an additional 180 days to regain compliance with marketplace Rule 4310(c)(4). What this means is that Beacon is going to do everything in its power to get the stock price back above $1. They had a nice run up to .80 in October but have since fallen back down to the .40 range. Shares in BCON are up 10% today on this reprieve.

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...

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 been awarded a contract through the Air Force Research Laboratory (AFRL), and co-funded by the Defense Advanced Research Projects Agency (DARPA) of the U.S. Department of Defense. The contract, valued at $750,000, is for the preliminary design of a space-based flywheel energy storage system for satellite applications, and is a Phase II award under the Small Business Innovation Research (SBIR) program of the U.S. Small Business Administration's Office of Technology. Beacon announced completion of an associated Phase I project earlier this year. This was welcome news for this company...

Beacon Power Corp (BCON) reported revenue of $304,064, compared to revenue of $80,902 in the third quarter of 2004, an increase of $223,162, or 276%. Revenues for the nine months ending September 30, 2005, were $1,258,503, compared to $264,793 for the same period in 2004, an increase of $993,710, or 375%. Beacon Power reported a net loss of $2.1 million, or ($0.04) per share, compared to a net loss of $1.9 million or ($0.04) per share for the third quarter of 2005 and 2004, respectively, representing an increase of approximately $0.2 million or 16%. They ended the...

Beacon Power Corp (BCON) announced that yesterday it received from the New York State Energy Research and Development Authority (NYSERDA) an executed contract between Beacon Power and NYSERDA under a joint initiative between the U.S. Department of Energy (DOE) Energy Storage Research Program and NYSERDA, to demonstrate an advanced energy storage solution for frequency regulation and grid stability in New York State. The contract is expected to produce approximately $645,000 of revenue, nearly all of it in 2005. The stock is trading up over 20% today on this news.

John Petersen Tom Lehrer is frequently credited with a quip that perfectly summarizes my feeling about the financial markets in the third quarter, "Apart from that Mrs. Lincoln, how did you enjoy the play?" During the quarter we were given box seats to classic political opera in two acts. Act One was set in Washington DC while Act Two moved to Europe so we could hear the same tortured songs of woe in a different language. We all know the opera has to end with the immensely popular "Kick the Can Chorus," but we suspended disbelief, bought into...

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.

John Petersen The next few days are going to be a very exciting time in the energy storage and electric vehicle sectors because the Obama Administration is preparing to announce a series of major ATVM Loan and ARRA Battery Manufacturing Grant awards. President Obama will be in Elkhart, Indiana where he will presumably announce an ATVM loan to Navistar (NAV) and may announce some additional ATVM loans or ARRA battery grants. Vice President Biden will be in Detroit where he is scheduled to announce one or more ARRA battery grants and perhaps some ATVM Loans. Secretary...
