Energy Storage

by Debra Fiakas CFA Last week management of Electrovaya Inc. (EFL: TSX; EFLVF:  OTC/QB) were forced to issue a statement stating there were no fundamental developments to explain a dramatic decline in its share price.  The stock was trimmed back by 30% in two days under exceptional trading volume.  Electrovaya has developed proprietary lithium ion polymer batteries for grid storage and transportation applications.  Other than financial results for the quarter ending March 2017, the Company has had little to tell investors about the batteries, its customers or any other topic. Electrovaya distinguishes its lithium ion batteries among...

by Debra Fiakas CFA The most recent article Vanadium Flow Battery Stocks: Barely A Dribble may have disappointed some investors who were expecting more opportunity for a stake in building energy storage.  Large scale energy storage is an idea to which many in the utility industry speak, but few power producers have made significant investments beyond lithium ion batteries.  Flow batteries have long been touted as a cost-effective and technically superior alternative for wind or solar power storage or for load-balancing efforts on the electric grid, as examples.  In the last post we looked at the flow battery...

by Debra Fiakas CFA   The previous post “Investing With The Flow Battery” introduced a series of articles on flow batteries for grid-scale energy storage.  Investors focused on renewable investments should at least consider the implications of storage requirements in evaluating renewable energy technologies even if storage developers are not considered portfolio-worthy.  Owners of grid-connected solar and wind power systems must design a network that can meet the highest peak load of the year even if a large part of the generating capacity sits idle for extended periods.  Storage technologies convert electrical power into chemical or mechanical energy...

by Debra Fiakas CFA   The looming threat of global warming has nearly everyone  -  except perhaps those bickering with each other in the Whitehouse  -  scrambling for lower carbon energy sources.  Intermittancy remains a stumbling block for several of the lower-carbon renewable energy sources, particularly wind and solar energy systems.  To be a serious contributor to grid-connected power systems these energy sources need utility scale batteries that can store energy when the sun is down or winds have died away.  Unfortunately, with current technology the cost of such battery capacity increases the levelized cost of energy (LCOE)...

by Debra Fiakas CFA Last month BioSolar (BSRC:  OTC/PK) reported positive test results for its proprietary energy storage technology.  The company is developing an alternative anode material for lithium ion batteries using silicon-carbon materials.  BioSolar’s engineers are targeting dramatic improvement in anode performance and equally impressive reductions in cost.  If they are successful, it could mean longer lithium ion battery life, greater capacity and shorter charging time  -  the dreams of every manufacturer with an electronic product. Most lithium ion batteries rely on graphite for the battery anode.  However, silicon anodes could offer as much as ten...

by Debra Fiakas CFA The series on graphite resource development is completed with a discussion of the companies that are currently in production.  The U.S. Geological Survey estimates 1.2 million metric tons of flake graphite are produced annually.  The vast majority  -  780,000 metric tons  -  are produced in China.  India and Brazil follow with 170,000 metric tons and 80,000 metric tons, respectively.  North America, which seems to show so much promise to the graphite resource developers that have been featured over the past few articles, is currently only contributing 30,000 metric tons per year to the graphite...

by Debra Fiakas CFA The Klondike Gold Rush of the 1800s has given way to the Canada Graphite Hustle of the 21st Century.  In what may seem to many an interminable series on graphite resources developers we have made note of over a half dozen companies in Canada attempting to bring new supplies of graphite ore out of the earth.  The action is not limited to Canada.  There are at least a dozen other aspirants with plots in Canada and the rest of North America as well as in Australia and Africa. Piecing together disclosures by the...

by Debra Fiakas CFA The market for lithium ion batteries is expected to reach $46 billion by 2022.  That represents 11% compound annual growth over the next six years.  Few other markets if any are growing at such a feverish pace.  The adoption of electric cars is the center of the excitement, but the proliferation of smartphones, tablets and other electronic devices also plays a part.  Suppliers of critical battery materials such as lithium, cobalt and graphite are salivating over potential sales to battery manufacturers. Graphite with its strong conductivity and heat-resistant qualities is a perfect material...

by Debra Fiakas CFA   Hydrogen technology developer and fuel cell producer  Hydrogenics, Inc. (HYGS:  Nasdaq) closed out last year ‘following on’ with new capital and new fuel cell orders.  The company staged a public sale of its common stock through what is frequently referred to as a ‘follow on’ offering, coming along as this one did some years after the company’s initial public offering.  The pricing of these new shares of common stock was ‘followed’ quite closely by announcement of a new order for Hydrogenics fuel cells by a forklift manufacturer in North America.  The appearance...

by Debra Fiakas CFA The post “Energy Storage Restart,” which was published last week, discussed the efforts by General Electric (GE:  NYSE) to get back into the market for utility-scale energy storage.  After some difficulties that required the partial closing of its battery manufacturing plant, GE has got back in the game with new contracts wins.  In April 2015, the company won a contract to supply Con Edison Development with an 8-megawatt-hour battery storage system at a solar project in California.  GE will be integrating lithium-ion batteries rather than...

by Debra Fiakas CFA The post “Energy Storage Restart” highlighted General Electric (GE:  NYSE) efforts to get back into the market for renewable energy storage.  Two of the company’s most recent contract wins requires GE to install lithium-ion batteries rather than its own battery technology.  This serves up an entertaining game of ‘who’s the supplier.’  Indeed, GE has partnered with a variety of companies for battery development and any of those could be candidates.  One of the reasons GE might have won two utility-scale contracts is its ability to manage large, complex...

by Debra Fiakas CFA In April 2015, General Electric (GE:  NYSE) won a contract to supply Con Edison Development with an 8-megawatt-hour battery storage system at a solar project in California.  The system will incorporate GE’s Mark IVe control system and Brilliance MW inverters.  However, instead of GE’s Durathon sodium-ion batteries, GE will be outsourcing or acquiring lithium-ion batteries for the project. Where will GE source the lithium-ion batteries for the Con Edison Development project?  So far, spokespersons have been non-committal on the name.  GE has had a number of...

by Debra Fiakas CFA A few years ago General Electric (GE:  NYSE) built out a manufacturing facility in Schenectady, New York for its sodium-ion batteries.  CEO Jeff Immelt declared the company a contender in the energy storage industry.  He projected that the company could ring up $500 million in annual sales by 2016, and build to $1 billion a year by 2020 by providing energy storage to utility-scale alternative energy projects.  Reality has been a bit different than Immelt's vision.  GE ended up shuttering the plant in the Fall 2014, and all but fifty employees were...

By Jeff Siegel Does Bob Lutz like Tesla (NASDAQ: TSLA) or not? The bigwig car exec who probably knows more about the car industry than practically anyone else, has certainly tipped his hat to the electric car-maker and to Elon Musk, but when it comes to the stock, he's perpetually bearish. Of course, I've yet to find anyone who can really make sense of the stock. On a technical basis, it's pretty much always been valued at levels that never really coincided with the reality. But the Tesla story has never been about just the technicals. Tesla's valuation...

By Jeff Siegel Last Thursday at around 11:00 p.m., the world changed. I don't mean to sound so dramatic, but there's no other way to put it. You see, that night, Tesla Motors (NASDAQ: TSLA)) CEO and super-genius Elon Musk unveiled something so monumentally game-changing, it's almost hard to put into words without sounding like a lunatic. But I'm going to try anyway... Out of the Starting Gate When I first started covering the renewable energy space in 2005, it was like pulling teeth to get investors to pay attention. After all, the renewable energy industry had a...

by Debra Fiakas CFA The last post “Man Makes Mother Nature Look Like a Lazy Maid” featured the work of Harvard scientists who have developed a breakthrough ‘bionic leaf’ system that uses sunlight to split water into hydrogen and then combine it with carbon to make isopropanol, an alcohol that can be used as fuel.  It is very much like reverse combustion.  Kudos to Harvard!  However, the good folks at Harvard are not alone in their quest to outsmart Mother Nature. In the late 1990s, the U.S. National Renewable Energy Laboratory in Golden, Colorado had reported progress...
