@ToolGuy The article is misleading IMO. It says they can "produce H2 for between 10 and 50 cents per kilo. This means it potentially costs a fraction of gasoline for equivalent output". This compares with current H2 production costs of around $2/kilo. Around 5% of the H2 produced then powers the oxygen production plant, so the system more than pays for itself."

If my calculations are correct, a kilo of H2 is about the same mass/weight as 1.4 liters of gasoline. Gasoline contains more energy per mass than hydrogen. In other words, a liter of gas moves a car further than a liter of hydrogen. Moreover, storing hydrogen as liquid requires either a heavy pressure tank or cryogenic temperature. Coupled with $2 cost per 1.4 liter, and higher pump prices, it seem unlikely hydrogen will ever be used as a transportation fuel. The cost of electricity per mile in a Tesla is perhaps a quarter of costs to run an ICE car. Hydrogen for fuel is the oil industry's gasping for survival.

@ToolGuy Time will tell. IDK what lithium mining sites ar like, but the worlds largest reserves, in Bolivia, has no trees. We will see about recycling. Everything we do has an environmental cost; we must work to minimize them.

@ToolGuy The Chinese have lithium, and they lead the world planting trees, and have reclaimed desert.

A coal power plant is 90% more efficient at producing electricity to propel an automobile then a internal combustion engine of any design is.

@ToolGuy whatever

Except bicycles, which should be encouraged.
