yeah, geological availability might vary

The fact that it isn’t tells me that there is a downside to always having your immune system on alert.

you know, it could just be that it consumes more energy and in nature, that’s expensive.

and chronic inflammation, i believe?

mice are not that different from humans, biologically

lots of countries have hosted US bases because they sold oil and made good business that way … now it’s becoming clear that they won’t be selling oil to the US in 10 years, so better start kicking them out now that they’re of no use anymore .

basically the caverns that are being considered/used for this are the same caverns that natural gas was extracted out of in the first place … they clearly held some sort of gas fine for millions of years, so certainly they’re gonna store a bit of hydrogen too.

hydrogen scales well if you use big industrial setups, both for generation and for storage.

basically, bigger tanks are cheaper (consider higher volume/surface area ratio) and in fact the best tanks might simply be naturally occurring underground caverns. you can’t have these at home.

eh, words are made up, you can just assign any meaning to them that you like

it’s not actually a lot of areas. this is the psychological effect of big numbers. you hear “one million acres” and think it’s a big number, like when government spends “one billion dollars on school programmes”, and it sounds like a lot, and your brain goes like “oh wow, i could never afford a billion dollars”, but actually, if you divide that by 300 million people (population of the US), it’s $3 per person …

same as with land. it’s like 20 m² per person on solar panels, probably less than some people’s garage.

That’s like saying, you cannot actually go to school, do homework and pass tests if you only reach a score of 99/100 points.

You can generate hydrogen from electrolysis.

Electrolysis efficiency is about 70% and you can store the hydrogen in pressurized underground caverns for a year or longer using another 0.12 kWh per kWh of hydrogen stored, which makes a total efficiency of around 0.6 kWh of hydrogen generation and storage for every kWh of electricity that you put in.

So if your electricity costs 6 ct/kWh (current LCOE of solar in many places), then hydrogen is gonna cost 10 ct/kWh to generate and store with current technology.

Currently, natural gas is around 5 ct/kWh, so solar would have to become a little bit cheaper to make it economically competitive.

Edit: to clarify, the 5 ct/kWh for natural gas is the gas alone; electricity from natural gas is more expensive than that (around 12 ct/kWh) and more expensive than solar.

what that sounds like some futuristic science fiction level stuff

when it goes in, it does feel good though

that video still lives rent free in my head … it’s way too hilarious

not my experience

and your back like you just asked it to do impossible things

it’s because the original image is actually hosted on i.redd.it which may cause issues, especially with weird HTTP headers which some software might struggle with and also with VPNs

no

yeah BILD is well known for that. but what about Welt?
