Phoenix Motorcars to use Electrovaya battery packs

Tuesday, May 6th, 2008

How does this impact Altairnano?

That’s the first question that came to mind when Electrovaya Inc., the Mississauga, Ontario-based maker of Superpolymer lithium ion batteries, announced that it is “negotiating a purchase and supply agreement and has begun work on a battery pack design and production program with Phoenix Motorcars.” The company said it has already received advance payment for upfront engineering design services and hardware production.

Electrovaya’s program is to focus on production of an integrated battery system and intelligent battery management systems for Phoenix’s long-range electric SUVs and sport utility trucks. Phoenix Motorcars will manufacture the vehicles at its California facility.

Perhaps Phoenix, which says it plans to deliver its first vehicles to fleet customers sometime this year, is hedging its bets, like GM and Think Global have been doing. The company has had warranty claim issues with its previously announced battery supplier, Altairnano, but as recently as March the company re-stated its support for Altairnano’s technology. “We wholeheartedly support Altairnano’s technology and believe they provide the greatest product available on the market today,” said Daniel Elliott, Phoenix Motorcars’ CEO in a statement in March.

The key word being “today.” That was then, this is now. Perhaps there are more underlying problems with Altairnano’s battery. Discussion boards are abuzz. So far today Altairnano’s stock is down 4 per cent on the news, which I’m sure hasn’t sunk in yet.

Electrovaya, itself no stranger to bad news, is on a roll lately. In January it announced a joint venture with Malcolm Bricklin’s Visionary Vehicles to produce battery packs for his plug-in electric hybrid car. The same month it announced it will “soon” be launching a low-speed electric vehicle called Maya-300 that will have a 120-mile range but be limited to 35 mph speeds. And last October is revealed it is establishing a joint venture with Electrotherm, the leading manufacturer of electric vehicles in India, with plans to build a manufacturing plant capable of producing 10-megawatt-hours per month of battery storage. The only problem, and perhaps this will change soon, is that Electrovaya is a penny stock that isn’t exactly flush with cash. So I’m waiting to see if someone will soon step up to the plate and provide much-needed funding for this company and its battery technology — a dark horse maybe in the HEV, LSV and EV races.

It bears repeating: PV lifecycle emissions low, and falling

Tuesday, May 6th, 2008

This research was reported back in February, but it was profiled again in a European Commission newsletter this month. It bears repeating, if only because there’s a lot of misinformation going around about how the energy that goes into producing solar panels isn’t much less than the lifetime energy you get out of it (claims I often hear — surprise, surprise — from proponents of nuclear and clean coal plants).

Researchers from Brookhaven National Laboratory and the EC’s Integrated Project CrystalClear used data from 12 solar PV manufacturers to determine lifecycle emissions from four different PV technologies: multicrystalline silicon, monocrystalline silicon, ribbon silicon, and thin-film cadmium telluride. Their findings, according to the newsletter:

“The thin-film cadmium telluride technology emitted the lowest amount of harmful emissions because it uses the least energy during production. However, the differences in emissions between these PV technologies were very small in comparison to the significant emissions that could be saved by switching from conventional energy technologies to PV. The researchers suggest at least 89 per cent of air emissions associated with electricity generation could be prevented if PV replaced energy from the average European grid.”

Even with the cadmium telluride approach, which produces heavy metals, it still found that this thin film process produced heavy-metal emissions that were 90 to 300 times lower compared to a coal plant fitted with the latest emission-control technologies. I should note that the cadmium telluride approach, used by First Solar, incorporates end-of-life recycling of heavy metals. Montreal-based 5N Plus, for example, is a main supplier to First Solar and places emphasis on its recycling services.

And, as processes for producing PV become more efficient, emissions will continue to fall. “Thinner films and greater efficiency are trends that will further reduce PV lifecycle emissions,” the researchers concluded.

For a 2006 paper from Columbia University that looks at lifecycle emissions of a 3.5 MW multicrystalline solar PV plant in Arizona, click here.

If one looks at data from the World Nuclear Association, they’ll see that solar PV is shown to emit three to 10 times the CO2 per g/kWh as nuclear. But you’ll notice that the data for solar PV is several years out of date. Given much of the advances around solar PV are only a few years old, one could easily challenge the assumption of the nuclear industry. What I’d like to see as an up-to-date comparative analysis between nuclear, wind, solar, natural gas, and coal. If anyone has see one, please let me know.
