Cobalt will go from drama to “calma”
Zachary returned to Cleantech Talk this week talking cobalt — and specifically, how a cobalt shortage won’t short-circuit the EV revolution. While we noted BMW reserving itself some lithium and cobalt supply, we focused on the reasons BNEF is confident cobalt won’t remain in short supply.
They used the example of solar-grade silicon, which spiked in price about 10 years ago. The shortage got resolved pretty quickly, and prices have continued plummeting, making everyone except First Solar shareholders happy. (First Solar’s stock had soared on the then-common assumption it would dominate the solar sector, then sank when it became clear solar silicon prices would plummet. From almost all accounts, it’s a healthy company, expectations had simply gotten way too high. Also worth noting is that several top solar companies — including in the crystalline silicon solar PV industry — have gone bankrupt from the rapid cost drops of solar.)
While I’m pretty sure cobalt will be cheaper in, say, 10 years than it is today, I’m not as confident that the price will be lower one year from now. While solar-grade silicon is a highly refined and purified product — it requires at least 6 nines of purity, or 99.9999% — cobalt is a metal, a commodity. And commodity price movements tend to be relatively slow.
After prices move upwards, it often take a few years for enough supply to come online (or for users to switch to cheaper materials) and prices to sink. A 40 year chart of copper shows this trend. Note that it’s not corrected for inflation, which means that in real terms, current prices probably aren’t *that* much higher than they were 30 years ago.
Meanwhile, CleanTechnica’s article on the warnings from Daimler’s “Dr Z” about the transportation transition possibly requiring supplier bailouts is here.
Car2Go’s success in Vancouver
While I still haven’t been able to find an online reference to Vancouver being the first place Car2Go has turned a profit, it’s definitely Car2Go’s most successful city on a per-capita basis, helping make Vancouver into North America’s carsharing capital.
I mentioned in the podcast a Berkeley study claiming each carsharing vehicle removes up to 11 autos from city streets. In a totally non-scientific poll of colleagues, the general sense was that carsharing allows most families to get by with one car, and forgo the second one. Even in Vancouver, only a small minority of households with kids are completely car-free.
And in the spirit of last week’s YIMBY theme, I’m more than willing to accept combustion carsharing vehicles if they remove demand for 11 vehicles (which will almost certainly all themselves be ICE vehicles). I’d strongly prefer for those carsharing vehicles to be ZEVs, of course, but I’ll embrace a fleet of combustion carshare vehicles if they knock out 10 times as much combustion vehicle demand!
