Battery based electric vehicles of today and tomorrow.

[Gale Hawkins]

Rodney Hooper may be the most knowledgeable person about EV battery raw materials sources and availability that I have heard speak.

He seems to think Tesla and VW have a good shot at coming up with source metals for their EV battery needs but it may be the last half of this decade before the Johnny Come Lately EV companies will have access to needed EV battery sources.

This could effective shut GM and Ford out of the European EV market for several years.

I went to CC to help me understand speech better.

Hydrogen Cell vs Lithium Battery – Car power comparison

In light of the near-term shortage of lithium ion batteries I think the companies that are ready to go with a fuel cell can figure out something with green hydrogen and make it work.

An EMD locomotive engine produces 1.75 MW of AC power.

In reality it don't. The engine drives the alternator and it produces the current and output depends on engine size. Locomotive engines come in various power ratings.

The 3 I installed many years ago produced 1.75 MW each. But yes, there are other sizes I’m sure.

"Green hydrogen" is pretty rare. Currently our hydrogen is either extracted from natural gas or uses coke to fuel 2H2O + C -> 2H2 + CO2.

Yes. Australia and a few others are using Solar power to drive the reaction perhaps.

I had the contract to haul the cranks and cams to Electromotive in McCook, Illinois when they were there, I spent a lot of time at the plant over the years. EMD fabricated engines from 4 cylinders to 24 cylinders, depending on application and required power output.

Interesting place I might add.

Supercomputers ID Materials That Turn Solar Power into Hydrogen

Planes, trains, trucks, ships and buses comes to my mind reading that.

That would have been really promising 30 years ago. I don't see how the infrastructure can be built out in time to do this generation any good. The chrome domes project we only have about a decade to stabilize atmospheric CO2 if we want to hold global temperature rise below 2.5 degrees C. We're already at 1.8.

I don't see it happening. EVs would be a great step, if we had a carbon neutral way of charging them. We don't. We have made incremental progress by converting coal power generation to natural gas, but every molecule of methane still has one carbon.

They have done some nice work on high temperature electrolysis. If solar panel prices keep dropping 25% a year, hydrogen may be a practical storage medium; electrolyze while the sun shines, feed hydrogen through turbines when it doesn't. I don't see nuclear or geothermal bailing us out any time soon. Wind is a nice paycheck for farmers where it's windy, but it's unreliable in the absence of long distance electrical transmission lines, which nobody is building.

It's hard to know where to place our bets. The critical property of energy is that it has to be cheap to maintain our standard of living in an industrial society. If energy expenses rise rapidly, it's going to make a mess out of the economy.

Nearly 100 Tons of Lithium Batteries Involved in Large Morris Industrial Fire

Nearly 100 tons of lithium batteries were involved in a large industrial fire in southwest suburban Morris Tuesday that led to emergency evacuations and a large-scale response as authorities warned of “highly poisonous” and “very deadly” fumes.
