Toyota wants hydrogen to succeed so bad it’s paying people to buy the Mirai::Toyota is offering some amazing deals for its hydrogen fuel cell-powered Mirai. That is, if customers can find the hydrogen to power it.

In a conference that in attended, they talked about usbhavimg to look at energy sources like a flow of energy and not as limited sources.

Currently, wind turbines are imtemtionally stopped, when there is so much wind that the generated electricity becomes too cheap to sell!

Instead, you could run them and use the electricity to convert the energy into hydrogen. Yes some energy is lost but it would be lost anyway as wind

With wind, sun, wave energy, we can look at energy in different ways that we usually do with fuel and coal. It's there and it just keeps coming.

Yes but the overhead we have is nothing compared to the energy needed to make everything hydrogen powered. we would need an absolute absurd amount of overhead to generate all the hydrogen from overhead alone.

It's kind of dumb to intentionally waste 75-80% of the total electric energy initially generated to power hydrogen vehicles.

Using hydrogen to store the occasional grid overhead to be used for the grid later is a great idea, it should absolutely be done ASAP...but it's not a solution to hydrogen powered vehicles.

A factory which only runs some of the time will be really expensive. From what I've seen it's way more cost effective to rely on batteries for surplus electricity.

So far grid scale battery storage only scales to stabilizing the grid. It’s better than anything else at that, but it’s not cost effective to for example power a town overnight until solar is back
