      Can ZBB Grab a Piece of the Energy Storage Pie?

      There are a lot of different technologies in the energy storage space.  ZBB Energy  has staked its future on zinc bromide.  Batteries using zinc-bromide consist of a zinc negative electrode and a bromine positive electrode with a porous separator in between them.  Unlike conventional batteries, these electrodes do not take part in the reactions but merely serve as substrates for the energy reactions.  Thus there is no loss of performance from repeated cycling causing electrode material deterioration.  The zinc-bromine battery can provide two to three times the energy density of lead/acid batteries.

      Clarifying the Confusion (about Stanford report on) the Cost Effectiveness of Storage

      Misinterpretations of a Stanford study on the energetic performance of energy storage recently published in Energy and Environmental Science appear to have added to the confusion surrounding this topic. To clarify a few misconceptions, we (California Energy Storage Alliance, or ‘CESA’) teamed with the Charles Barnhart, the lead-author of the Stanford study, to set the record straight.

    3. Opinion: Exide - Many Alliances, Fewer Results

      Opinion: Exide - Many Alliances, Fewer Results

      if Johnson Controls acquires A123's assets, Exide may be under more competitive pressure.  The deal would involve the transfer of supporting technologies and could give Johnson Controls an edge over Exide in the transportation market that appears to be centering on lithium ion technologies.  That means Exide will need to do more than bootstrap its reputation as an innovator with press releases and MOUs.

    4. Analysis: EVs, Batteries and Tales From The Valley of Death

      Analysis: EVs, Batteries and Tales From The Valley of Death

      Survivors include Active Power, Exide, Maxwell, ZBB, and Axion Power. These companies have avoided catastrophic errors and grown their businesses through determination, focus and fiscal restraint ... Beacon Power, Ener1, and Valence were complete and utter failures that ended up in Chapter 11.  Altair Nanotechnologies avoided a total loss by selling control to a Chinese company after its stockholders lost 90% of their value. A123 Systems is on the deathwatch and seems unlikely to survive the year.

    5. Opinion: "All-in costs" of a storage system

      Opinion: "All-in costs" of a storage system

      An analysis of energy storage device costs is meaningless at anything less than a systems level that includes the all-in costs of cells, packs, thermal management systems [TMS], battery management systems [BMS], power conditioning systems [PCS], and, in the case of stationary products for the electric grid, land, construction and interconnection costs

    6. Stock Analysis: Energy Storage Q3 2012 Winners and Losers

      Stock Analysis: Energy Storage Q3 2012 Winners and Losers

      I expect three companies in my tracking group to perform very well in Q3 – Exide Technologies ( XIDE ), Active Power ( ACPW ) and Axion Power International ( AXPW.OB ). All three look terrible if you only look at historical performance, but when you dig deeper into business history and market dynamics it becomes clear why all three have market-crushing potential over the next three to six months.

    7. Analysis: EV Dreams and Industrial Metal Nightmares (also applicable to stationary storage metals)

      Analysis: EV Dreams and Industrial Metal Nightmares (also applicable to stationary storage metals)

      The numbers simply can't work.  For every 100 pounds of energy resources, our planet can produce ten pounds of iron and steel and one pound of nonferrous industrial metals. If you'd rather tighten the focus to oil and the specific industrial metals that are essential for electric drive components, the ratio works out to eleven ounces of industrial metals for every hundred pounds of oil.

      Opinion: Lux's analysis of 8 grid storage technologies in 6 applications in 44 countries

      Lux Research released a bottom-up evaluation of the cost effectiveness of eight energy storage technologies in six grid-scale applications throughout 44 countries.  "Grid Storage under the Microscope: Using Local Knowledge to Forecast Global Demand" predicts that annual global demand for grid-scale energy storage will reach an astounding 185.4 GWh by 2017 and represent a $113.5B incremental revenue opportunity for an industry that currently generates sales of $50 to $60B a year.

      Opinion: Ranking Li-ion Battery Stocks Using Lux “Innovation Grid”

      I'm often critical of public lithium-ion battery manufacturers based on objective [financial] metrics … but I don't drill down into issues like technical merit … The “Innovation Grid” graphic from Lux Research can help investors cut through the hype and make better investment decisions [about Advanced Battery, JCI-Saft, Ener1, A123].

      Opinion: Upcoming Massive Glut of Li-ion Batteries

      Lux forecasts a catastrophic supply and demand imbalance in the lithium-ion battery sector over the next decade … The Lux forecast is bad news for diversified first tier manufacturers like LG Chem, GS Yuasa, SB LiMotive, AESC, and Sanyo; terrible news for financially sound second tier manufacturers like Toshiba, Hitachi, and JCI-Saft; and an "existential threat" for emerging third tier battery developers like A123 Systems (AONE), Ener1 (HEV), Valence Technologies (VLNC) … that were counting on transportation markets that are unlikely to develop.

    11. Opinion: The Alternative Energy Fallacy

      Opinion: The Alternative Energy Fallacy
      The basic premise of alternative energy is that widespread deployments of wind turbines, solar panels and electric vehicles will slash hydrocarbon consumption, reduce CO2 emissions and give us a cleaner, greener and healthier planet. That premise, however, is fatally flawed because our planet cannot produce enough non-ferrous industrial metals to make a meaningful difference and the prices of those metals are even more volatile than the prices of the hydrocarbons that alternative energy hopes to supplant.
