So they used to be ridiculously cool, but they’re still ridiculously cool too.

of course not

Because hydrogen isn’t trying to replace the source of energy, it is trying to replace the storage of it

yes, but the point is renewables>battery storage is a more direct and efficient storage system than renewables>hydrogen which then has to be contained, shipped, and distributed for every refill/charge. Batteries you make once and recharge thousands of times which you can do with distribution through the grid from your local power utility (or even right at home if you have solar).

at present batteries are not nearly good enough for the EV only transportation boom, but hydrogen works and only really needs to deal with the volatility issue

it’s not just volatility that’s an issue. Even setting that aside, Hydrogen is difficult to contain because it’s such a small molecule, and it weakens/corrodes metals. These are not trivial challenges at all.

the other thing you can’t do with hydrogen is energy recovery via braking, so you’d have to build cars with a battery or some other kind of hybrid system for fuel cost efficiency.

It’s true that batteries present their own challenges but we are making much more progress in battery tech than we are with hydrogen.

Dont most people know that?

most people do not know that in my experience.

thought the promise is that you could establish a hydrogen infrastructure and it would get greener over time - similar to EV’s which get greener over time as power generation includes more renewables.

why should we use renewables to produce hydrogen (not to mention develop an entirely new hydrogen infrastructure) when we could just use that renewable energy as it is? That’s just adding extra steps and inefficiency for very little benefit, if any.

One of the most satisfying parts of owning an EV is thinking about all that industry that no longer needs to exist.

agreed.

play stupid games win stupid prizes.

also most hydrogen is a byproduct of fossil fuels. very little hydrogen is made with green energy.

edit: 95% of hydrogen is produced directly from fossil fuels. Truly "green"hydrogen is less than 1%.

what reason do they give for removing the feature?

or you’re about to go to a high school very soon!

problem is solar and wind are variable and not feasible everywhere. for places like australia solar is amazing. Winter in canada? not so much. So for a baseline you’d have to store a massive amount of energy in some way.

if you plan on batteries that requires lots of precious metals we will need elsewhere to aid in the transition to electric power.

generally agree but tech firms are looking into small modular reactors sized for datacenters.

disagree, they are entirely different operating models. reddit was privately funded and eventually snehittified to become profitable. Lemmy is free, but still needs funds to operate. Might as well make it fun and rewaring to participation rather than just annoying banners whenever things get tight.

lemmy feature request please - lemmy gold.

even if that is the case it’s a good sign imo. it means people were causing an impact big enough for them to notice and take action.

even that is a good sign. it means there’s was enough of an effect for them to take action.

i had optimism they’d handle star wars well given how they handled marvel up to that point. unfortunately they learned absolutely zero lessons from that success.

Newsweek is shit. most of their articles are just left wing hopium with no substance whatsoever.

THERE ARE DOZENS OF US

pandora was the shit like 10-15 years ago.

how could you be radicalized with the truth?

never mind people in the internet, maybe let’s start with the people in congress and on television. oh and, you know, the fucking president.
