Gas 2.0

In December, amidst much gleeful hand-wringing, the imminent demise of all the alternative car companies and electric vehicle start-ups was all over the intertubes, as our second Gilded Age crashed this fall into “the worst depression since the Great Depression”.

Headlines full of schadenfreudly screeches like “Oh no! Tesla sedan delayed five minutes! Now surely they will go out of business!” “Another EV startup bites dust!” were gracing a gleeful media.

Among these alarmist statements was a much touted story about the near-death of TH!NK, the Norwegian EV maker, which had been scheduled for U.S. delivery in 2009.

Never mind that TH!NK had placed a $70 million dollar battery order with Enerdel a few months previously. Now, all was lost. No $25,000 freeway speed EV for America.

Well, think again, pundits. After the virtual collapse of the company last month, the U.S.A. (where the original TH!NK was murdered by U.S. lawyers fighting CARB zero emissions rules in the 90’s) could be just where the TH!NK gets resuscitated this year. How ironic.

Since the late 1800s, the primary impediment to the adoption of electric vehicles has been battery technology. And while the technology has advanced by leaps and bounds in the last decade or two (compare your cell phone with one from the early 90s), with a threefold improvement in energy density and more than an order of magnitude improvement in power density, it still lags behind gasoline.

Some have argued that current technology is sufficient — that the ability to drive 1 1/2 hours to 3 hours nonstop is good enough for the overwhelming majority of trips, and that paired with a range extender, rapid chargers, or battery swapping, you have a viable means of replacing the gasoline car. However, there still is a great deal of pressure to get electric vehicle range up to that of gasoline.

Enter Yi Cui. Again.

Ice Storm Victim Improvises Prius-to-Home Energy Generator

A Massachusetts man – faced with no power in the recent ice storm, powered up the family Prius to create electricity: The hybrid car made enough electricity to run the essentials; the fridge, the lights, the TV, the wood-stove fan. During the power outage, it supplied 17 Kilowatt hours of energy to his home for three days.

Battery provider Southern California Edison (SCE) has demonstrated a lithium ion battery with a lifespan of more than 180,000 miles, a major milestone in advanced battery performance that opens the door to a new generation of electric cars.

Since the average U.S. family car travels less than 15,000 miles each year, the battery could easily provide more than ten years service before it needs replacing. When you factor in the relatively low servicing costs of electric cars, this means that there is now a compelling case for such technology to power future plug-in vehicles.

Better Place and Hawaii have joined forces. This week the State of Hawaii and the Hawaiian Electric Company endorsed a plan to build a new renewable transportation system based on electric vehicles with swappable batteries and a “smart” battery recharging network.

The Better Place plan solves the current problem with electric cars, which is slow battery recharging as well as availability. The solution is to use existing electric car technologies together with an internet-connected web of recharging stations (set up in the thousands). Read the rest of this entry »

Researchers are reporting they have developed a new material made from three-dimensional, highly porous nano-silicon that could give future lithium ion batteries a ten times higher capacity than they currently have.

The storage capacity of current generation lithium ion batteries remains a bottleneck for the widespread adoption of electric cars due to a perceived limited driving range. Although we could argue whether a 100-130 mile range really is that much of a limitation or not, perhaps the better solution is to be able to ignore that argument altogether by increasing battery capacity.

What do you get when you combine some of the most advanced pieces of green technology in the marketplace today? It might look something like the new EcoSaver IV hybrid buses from DesignLine.

First, the basics. The buses in question are built by North Carolina-based DesignLine International and feature wide entry doors, super-low floors, and room for 42 passengers. Earlier versions of the EcoSaver hybrid system have been powering these buses for the past ten years. As far as mass transit goes, not a bad start. However, it gets even better when you peek under the hood of the latest generation.

A while back, Toshiba unveiled their first foray into advanced lithium ion batteries — the Super-Charge ion Battery, or SCiB. Over the past few days, new information about their cells has emerged. With a 5-minute, 90% charge time and 5000-6000 charge cycles with minimal loss of capacity, it seems a solid competitor to AltairNano’s much vaunted nano-titanate cells.

Toshiba has already demonstrated a laptop that does just that, charging to 90% capacity in 5 minutes. This compares favorably to lithium iron phosphate technology, which should not be charged faster than 15-20 minutes. A partnership with Schwinn is to ship an electric bicycle (“Tailwind”) early next year using an SCiB pack to give a 30 minute recharge time (assumedly slower to avoid the need for a cooling system on the larger pack).
