Nimrod - good comparison. I’ll try following it up. As you say chargingtime is an issue but probably also supplies of lithium. I guess if lithium mining/refining used renewable energy then CO2 use per km would too - like with H2. Leaving charging time and chinese stranglehold on lithium as issues. Plus weight per kw hour.

Hydrogen vs Battery
extract from "The Week"
“As an example, a 100kWh battery will give a potential range of 250 miles and, in order to produce that battery, it will take around 20 tonnes of CO2,” he said. “A typical battery lasts for 150,000 miles, so that equates to around 83g/km of CO2. Then, when you take into account charging over that same distance, the same battery car will deliver 124g/km of CO2 over its lifetime.”

By comparison, Auto Express says that a recent study found that a Toyota Mirai hydrogen fuel cell car produces around 120g/km of CO2 over its lifetime when the manufacturing process is taken into account. But if hydrogen were to be produced by renewable energy, that figure could be reduced significantly.
After reading the Hydrogen article this weekend in the Telegraph I was surprised by the number of adverse comments. It appears to me that EU governments are heading in to hydrogen, so whats the reasons not to go in to batteries??
My own observation is that batteries take so long to be recharged as the biggest drawback if wishing to travel a long distance, plus the cost of replacement batteries if fast charged. Am I missing something??

Skinny: perhaps we should start thinking about which hydrogen producer companies would be the most likely targets of the big oil companies looking to transition their large petrol station business into hydrogen gas tanking. Much better for them than people charging electric cars at home. In fact if they built windfarms on man-made islands in the north sea and produced the hydrogen there, there would be very little change in the structure of their business.

Maybe its because Hydrogen is lighter than air !!! The Hydrogen stocks just keep rising.

quote from conversation on Yahoo Finance
"• Bloom Energy is entering the commercial hydrogen market by introducing hydrogen-powered fuel cells and electrolyzers that produce renewable hydrogen. These products will be first introduced to the South Korean market in 2021 through an expanded partnership with SK Engineering and Construction (SK E&C), an affiliate of SK Group. Bloom's existing partnership with SK E&C has already sold 120 megawatts (MW) of fuel cells in South Korea, generating over $1 bln in equipment and future services revenue for Bloom.
• By the end of 2020, Bloom expects to ship a 100 kilowatt pilot Server to South Korea to power an SK E&C facility in early 2021. The second phase, a 1 MW hydrogen Server installation, is targeted for a 2022 deployment. Both companies have committed to fully fund and resource these two phases.

Yes wouldn't it.

Skinny: it would be interesting to know whose fuel cell will be powering H2Haul
