> My gut is that the majority of hydrogen proponents are oil and gas lobbyists or funded by them I don't understand how any one looks at the electric car charging situation and thinks it makes sense to scale that out to 100% of vehicles. A 2 hour wait to get a charger spot isn't a workable transport system.
The future is public transport.

Am not well versed on these considerations but it appears one advantage of hydrogen is energy density compared to batteries. This may be less an issue for passenger vehicles but could be more relevant for air travel - as an example. No comments or opinions otherwise re: funding etc. Found the below article useful as a primer: https://www.energy.gov/eere/fuelcells/articles/fuel-cell-and...
Anybody who needs to run 24/7 and/or can't count on an electric grid could use hydrogen power: A logistics network, an army, public transportation, utility companies, forestry or mining...
Hydrogen may be a solution along with other hybrid approaches (WA state ferry electrification being relevant [1])

The argumentation is flawed. 1. Just imagine the required charging infrastructure if all vehicles were suddenly battery powered. Charging electric vehicles requires quite some power. Can the power grid installations sustain that (power lines, Transformer stations...) ? What resources (financial and physical (e.g. Cooper)) are required in order to adapt the infrastructure ? Just an example: A supercharger station whic…
Re 2: Batteries keep getting cheaper due to economies of scale. Batteries for grid stabilization don't need high energy density and will soon (or maybe already are) more cost effective than pumped-storage hydroelectricity.
They oil industry are filthy liars, aided by petrostates like KSA and Russia. They are like the tobacco industry, but many thousands of times worse.
Anyone who has followed hydrogen as a fuel for a while sees pretty easily that its a solution in search of a problem. It really doesn't make sense to use renewables to make hydrogen fuel to then burn: batteries are better for storage of energy in most cases (I will grant that there are edge cases where a liquid/gas fuel is a better technical solution than batteries, but I think that options like ethanol are probably…
Hydrogen for cars is dead. However long haul flights, fertilizer, green steel, etc. very difficult to find a carbon free alternative that isn’t hydrogen.
Electrification for millions and millions of cars will never work, we don't have the "green" energy resources to actually produce that electricity, and second, and just as important, we don't have the distribution network that will be able to carry that extra power (both in the US and in Europe). So that leaves us with the logical conclusion that we won't have millions and millions personal cars going forward, for be…

What does 100% look like in California (definitely unrealistic, but can be scaled)?
California uses 13 billion gallons of gasoline, per year [3]. Let's say electric is 50% more efficient than gas, so we'll need 6.5 billion gallons worth of energy. At 33.7 kWh of per gallon of gas, that's 219 TWh of energy per year. In 2020, California produced 277 TWh [4]. They'll need to nearly double energy production, which matches most developed countries in Europe.

You know what does make it make sense? If you can take natural gas out of the ground, split it into hydrogen and CO2 (releasing heat, which can be used to generate electricity), and inject the CO2 back underground to help release more oil and gas. At this point, you have hydrogen gas. Sure, you could burn that hydrogen to make more electricity, but it works out financially better if you can directly use it. The benef…

There is an Oil Sector Lobby and there is an electric sector Lobby too. All Lobbies hate competition. The electric sector wants to destroy Hydrogen because it competes with them, of course, they want to destroy the seed so no tree comes out of it. Hydrogen disappearing is not going to happen, because it going to be necessary for some things, like heavy transportation. Just because clean Hydrogen is in the early stage…
