Why Lead-Carbon Batteries Will Deflate the Lithium-Ion Bubble
John Petersen For over a year I've been cautioning readers that while lithium-ion batteries are glamorous, sleek, sexy and hot; they are about to face a formidable challenge from lead-carbon batteries that are a little bulkier and heavier, but offer competitive cycle-life and power for a tiny fraction of the cost. To placate lithium fundamentalists and EV evangelists, I want to clearly state up front that lead-carbon batteries will probably not be the first choice for plug-in vehicles. Nevertheless, it is crystal clear that lead-carbon batteries will be the only sensible choice...
Electro Energy Delivers Silent Watch Battery System
Electro Energy Inc (EEEI) announced the delivery of a Bipolar Battery System to the U.S. Army Communications and Electronics Command (CECOM), to be tested and demonstrated under the Silent Watch Program. The EEEI bipolar battery system was built under the Company's contract with the U.S. Army Manufacturing Technology (Mantech) Program. The EEEI system, comprised of three 1kW modules, could be operated individually or as a complete system with a 3kW power capability, which would provide on-board vehicle electrical power to operate in Silent Watch Mode for three hours compared to the existing lead acid capability of 45 minutes....
EPA and NHTSA Predict 42% Market Penetration for Start-Stop Systems by 2016
John Petersen On April 1st the National Highway Traffic Safety Administration and the Environmental Protection Agency announced a joint final rule establishing fuel economy standards for all light duty vehicles sold in the United States. In my last article, I focused on the overall fuel efficiency improvements the new CAFE regulations will require. After spending a couple days reading and digesting the Final Rule Release, which runs to 1,469 pages, I've concluded that my initial optimism over the future of start-stop technology was understated. The Final Rule Release begins with several hundred pages of introductory...
Vanadium Flow Battery Companies
The recent post “Lithium Technology Dominates Large Energy Storage Projects” featured companies offering utility-scale lithium battery systems. Industry research firm Navigant estimates that lithium-ion technology accounts for almost 30% of non-pumped storage capacity developed since 2011. This might be due in part to the dramatic decreases in cost for lithium ion batteries. A study completed by Bloomberg New Energy Finance found that the ‘levelized’ cost of energy for lithium ion batteries has fallen by 76% to $187 per megawatt hour in the first quarter 2019 from $800/MWh in 2012.
Is the story over for utility-scale storage? Should investors look for lithium ion battery manufacturers and forget...
Just One Sector – Fuel Efficiency Pure Plays
John Petersen In 1789 Benjamin Franklin wrote "in this world nothing is certain but death and taxes." Today he probably would have written "in this world nothing is certain but death, taxes and rising oil prices." There's no escaping the misery, but astute investors who take the time to understand the fundamental trends can profit as the misery unfolds. For the short term, I'm convinced the biggest opportunities will be in fuel efficiency technologies for cars and light trucks. After 20 years of complacent stagnation, the US started to get serious about light-duty vehicle fuel efficiency in...
Arotech Receives Order from US Air Force for Man Portable Zinc-Air Batteries
Arotech Corporation (ARTX) announced today that its Battery and Power Systems Division has received a pilot order for its new 4th generation man portable Zinc Air battery packs from the US Air Force. Developed and manufactured by its Electric Fuel Battery Corporation subsidiary, Arotech's new battery pack is a 12 or 24 Volt battery with a total capacity of over 400Wh and Battery Energy Density of approximately 300Wh/kg. The new battery pack is optimized for use in vests, as man portable tactical radios are typically vest-worn in holsters. The pack is also designed for use in rucksacks. ...
PHEVs and EVs; Plugging Into a Lump of Coal
John Petersen Since I've stirred up a hornet's nest over the last two weeks first by debunking the mythology that PHEVs and EVs will save their owners money and then by showing how PHEVs and EVs will sabotage America's drive for energy independence, I figured I might as well go for the triple-crown of harsh realities by showing readers that in the U.S., where 70% of electricity comes from burning hydrocarbons, PHEVs and EVs won't make a dent in CO2 emissions. They'll just take distributed CO2 emissions off the roads and centralize them in coal and gas...
Pure Play Energy Storage Stocks Year-End Review And Outlook
John Petersen With only a couple trading days left in 2009, this is as good a time as any for a performance review. The predictions I made at this time last year were pretty solid with an 80% accuracy rate on price direction. For the year, a $1,000 investment in each of my green star companies would have yielded a portfolio appreciation of 67%, which handily beat the broader market indices. That being said, my star and caution ratings were a good deal less prescient because I seriously underestimated the potential of both Maxwell Technologies (MXWL) and Active...
