In the BHP thread ducati is presenting a case for the irrelevance of electric vehicles (EVs) and hybrid electric vehicles (HEVs) on the copper market.
EVs and HEVs are very different creatures.
EVs do not have a conventional internal combustion engine (ICE) – the electric motor substitutes for it completely.
HEVs have an electric motor and an ICE (albeit smaller as it generates electricity for the electric motor.
Using ducati’s own (10 year old) data for EVs, the substitution effect of an ICE for an electric motor adds between 9 and 16 kilograms (ducati uses 20lbs to 35lbs).
Globally there are upwards of 500 million cars on the road.
What would happen if we had to convert all of them to EVs within 20 years because fuel/oil was too expensive?
If we assumed every kilogram of copper from existing cars could be recycled then we would need at least an extra 4500 million kilograms of copper just to service this scenario.
Dividing this evenly over 20 years (for simplicity sake) means we would need 225 million kilograms of extra copper each year to make EVs. The good news is that the global stockpile of copper at LME, Shanghai and Comex warehouses is presently about 226 million kilograms (although over 10 million kilograms is already committed).
So, we can accommodate year one of the EV scenario.
What do we do in year two?
Will the global copper stockpile increase faster than it is depleted, and give us some breathing space?
Perhaps.
Unfortunately EVs are presently subservient to HEVs in the manufacturing stakes.
US consensus data suggests HEVs require twice as much copper as cars with ICEs only. (In the BHP thread ducati has not been able to discern the difference between EVs, HEVs and total copper use as wiring plus copper alloy materials. This is important as, for example, HEVs don’t just have an electric motor and ICE, they also have a generator and a converter, plus supplementary wiring unique to HEV systems.)
Toyota is the global leader in manufacture of HEVs, and since introducing its Prius in 1997 has managed to produce just over one million HEV units (inclusive of others in its HEV fleet range eg Rav 4s).
Clearly, the move to HEVs and EVs is not going to happen quickly, and converting 500 million cars over the next 20 years would be a production challenge of mammoth proportions.
But wait, there’s more.
Industry analysts reckon there could be a billion cars on the road in 20 years time. Yes, believe it or not, the challenge will not just be to convert the status quo to EV/HEVs, it’s to accommodate global growth in car ownership, especially from emerging nations.
Quickly back to the HEV calculations.
In the BHP thread I used US data.
The average US car contains over 25 kilograms (copper Development Association states 27.4kg in 2006) of copper (wiring and alloys).
HEVs are estimated to require double that amount, with lower end vehicles (with less electronic gadgetry) requiring upwards of 50% more copper than present average.
Thus, we are looking at HEVs requiring between 12 kilograms and 25 kilograms more copper per vehicle.
Going back to ducati’s EV number of 9 kilograms (or 20 lbs as he prefers), we see HEVs consuming at least 3 kilograms more – a 33% increase.
Given the present copper stockpile could barely accommodate a 9 kilogram increase per car spread evenly over 20 years, it will struggle with a further 33% increase in demand.
The above has been kept deliberately simple for demonstration purposes, but remains conceptually feasible in the longer term.
The challenge for those continuing to believe that EV/HEVs are going to be irrelevant to future copper demand/supply is to prove that the combined effects of recycling and ICE substitution are negligible.
