@SaveMoneySavethePlanet Nobody is going to invest in hydrogen factories that just sit around waiting for some excess energy.

Yeah veganism is great but electric vehicles will also play a massive role.

It is not because batteries are already far more effective in lowering CO2 emissions.

@SaveMoneySavethePlanet So to conclude: there won’t be any significant amount left for hydrogen.
2
@SaveMoneySavethePlanet Sure, but it will be many decades to come and even then there are better ways to make use of excess energy. Hydrogen will always be all the way at the end of the line.

Inefficient and causes food vs. fuel conflicts.

Lol it was not revolutionary and he was not killed.

A hydrogen system is not simple at all, especially compared to a battery electric situation.
1
Not at all. EVs are barely heavier than hydrogen cars. Also, weight barely affects overal efficiency.
1
It’s not and hydrogen cars require platinum, lithium, nickel and cobalt too.

@hafizuddin mohd lowhim CO2 emissions are far more important
1
@hafizuddinmohdlowhim8426 Only for a tiny part. Batteries will dominate.

@hafizuddinmohdlowhim8426 thanks

Electricity will never be free. Therefore driving on hydrogen will always remain 3 times as expensive.
1
It’s not dishonest. Both hydrogen cars and EVs require the same electricity. But hydrogen cars waste massive amounts of that along the way.
1
Not at all. Emissions of energy consumption during use of the vehicles has a far higher impact on life cycle emissions. Battery production is currently at < 100 kg of CO2 per kWh produced. That is easily compensated for within the first few years of driving.

You don’t need home charging to drive an EV. Curbside charging works fine and can be done with smart charging controllers that vary the power during the day. Even 1 to 2 kW for overnight charging is enough for your average driving.

@fidalfadel About 8 chargers within a one minute walk around me. It is a lot of work indeed, but definitely possible. It’s a gradual process.
1
It doesn't matter where the electricity for the hydrogen production comes from. It always remains inefficient.
1
Hydrogen is not a source of energy.
1
Burning hydrogen is a massive waste.
1
Wrong. EVs have been efficient from day one.
1
@Mogadypopz Lead acid battery recycling never was a problem. Apart from that, the point is that EVs have always been efficient, hydrogen cars have not and never will be.
1
Batteries compensate quite quickly for their production emissions because of their efficiency. A hydrogen system is inefficient its entire life.
1
@absolutium Still far better than the low efficiency of hydrogen systems.
1
There is more than enough lithium on earth than we will ever need.
1
It's not really relevant that the hydrogen itself is abundant or not. Guess what, electrons are also endlessly available.
1
Resources for batteries are not really a problem. Is it challenging? Yes. But it is just a matter of ramping up extraction. Hydrogen cars also require materials like platinum, lithium, cobalt and nickel. Due to their lack of efficiency hydrogen cars will also require three times as much energy, so three times as many solar panels and wind turbines need to be built and maintained.
1
It DOES matter because solar and wind energy are not free and will never be free and they are also not abundant at all.
1
Still far better than anything else.
1
@allangibson2408 In the future there will be so many battery applications (mainly EVs) that there wont be much excess left.
1
You should realise that hydrogen vehicles require 3 times more energy than an EV. So three times as many wind turbines and solar panels have to be built and maintained. Current EV batteries will last just as long as the vehicles themselves.

Well said
