This isn’t going to let us electrify the transportation decrypt. Here’s some back of the envelope numbers. An ICE is about 33% efficient at converting chemical energy to kinetic. I don’t know how efficient this process is, but to be generous, I’ll guess 75%. (I could be way off!) Factor in transmission losses of about 2% to the refinery and 5% losses to distribute the fuel, and you get about 6% of the generated electricity making its way to kinetic forward motion. Contrast this with an EV, which has a battery roundtrip efficiency of 99% and motors of around 85-90%. The end result is about 80% of the generated electricity getting used.
Now, I hope we can electrify the transportation sector, but our current generation and transmissions systems are inadequate. I am did he calculations for the state of California, and found that they would need to be roughly doubled in size. An immense undertaking, but a doable one.
However, I do not see us increasing the electricity generation and transmission systems by a factor of 25, which would be required for this technology.
