Here your source. Well you were talking about H2 being the efficient option. There is energy efficiency, volumetric efficiency, life cycle (in the sense of how long does the plant last, wind turbines last for 20-25 years, how sustainable are the resources and are they recyclable), even plant space needed.

As it stands now H2 prices need to go up for it to make green H2 competitive. Idk what you are on about, milk prices are a symptom of farmers wanting enough compensation for their work, that’s why you find milk for different prices depending on the form of agriculture. More land for the cow and organic will mean its more expensive, you can’t make this any more competitive because it isn’t. Grey H2 also produces energy in production and you can’t compete with that, hence the price of H2 needs to go up e.g. via CO2 tax.

Storage storing energy is indeed the point of it, but the question is also how much money do you want to pay for the energy? Did you buy any oil recently?

That is all besides the point though in a process where H2 is both produced and consumed, as long as that

I wouldn’t produce 1g silver when I produce 1g gold in the process, I make more money with the gold,. Thats why it isn’t competitive.

It appears it isn’t, even compared to air compression,

efficiency of green hydrogen is low and storage of it is hard, fuel cell efficiency is also low I think it ends up with about a 20% efficiency but don’t quote me on that. Also you’d like to sell it to the industry anyways. But they take it from cheap gray sources right now so whatever.

However there is no technological reason why one would need some carbon source for producing H2. Electrolysis from water is a well established process.

The scales of electrolysis aren’t as big yet (maybe now idk, but 2-3 years ago they weren’t), compared to methane processes. They also don’t produce their own energy, they take energy instead! (Get 2 H2 from CH4 and burn the C to CO2, compared to electrolysis which takes energy)

Insulations can be pretty good idk. But yea there are losses. As for LNG, that has uses for many countries with no natural gas or pipeline, so it seems to be worth to cool NG down. Not sure about Air because the heat energy from burning NG makes it desirable to have.

But also liquids have the advantage of taking way less space and not as high of a pressure as simple compression because of that. Which one is preferred is situational, I just wanted to correct you that it is a liquid

This needs a huge amount of energy surplus to provide enough in the summer and using ammonia for heat/energy is in direct contrast to using it using it for the market isn’t it? Except when you’d only use the expansion of liquid to gaseous and then use gaseous ammonia in a nearby plant. My guess would be anything green H2 will be too high demand and expensive to use as a fuel

H2 is used for many other products (steel reduction, ammonia), right now its produced from methane. If we were to replace methane with a green source (aka when green storage systems would also be a big part of the ecosystem) then we’d need to replace it or the price for anything would explode, because we can’t produce anything without steel nor ammonia.

So its not really of much value right now, but if we want to make everything CO2 neutral, then hydrogen will be expensive. So noone will just produce it and not sell it. At least that is my prediction.

Its liquid, so its probably also cooled down and pressurized

Also not great for H2!

Is ammonia a larger market because they produce their own grey H2 in the process of making ammonia?

Idk about the cryogenic/liquified part of it but h2(g) is really corrosive and notorious bad for all kinds of storages because of that. Also imo h2 isn’t the best storage because it is too valuable in industry processes, a good way to get rid of excess energy but not to feed energy back into the system.

The other part being the energy put into the electrolysis, yes h2 has more energy, but a whole extra process + buffer storage and turbines and compressors that are h2-able.

N2 is inert

Friedens kowai yo… kurai yo in the mimic healed that misconception

Relatable

I just found out about DMs a few days ago and I think that its awesome, anyone want to chat? Any creepy woman on here?

Tutorial hell might be some type of procrastination. I’d watch YouTube videos all day on all topics because I didn’t want to create something and just “learn”, but it doesn’t create real skill and it is not where the fun lies.

The biggest challenge might just be to find the thing you want and can do. If you really want to learn, then you might just regulate your want to some beginner level that is borderline useless.

Take language leaning for example, you want to speak enough to understand a conversation, but as this takes a LOT of time it gets frustrating really fast. What you can do is learn a simple sentence and try to speak it and understand it. “Good morning, how are you doing?” — “Guten Morgen, wie geht es dir?”.

Or programing, don’t think about this huge project, but a simple simple action; read variables from a document or create a function for some math. One of my first programing was calculating Fibonacci numbers.

In my opinion it might not be so bad to be stuck in tutorial hell, it might just be a form of entertainment for you. But if its a form of addiction, then maybe treat it as such. If it is a form of escaism then treat it as such. If it is adhd or autism or something else then treat it as such. Take simple and small steps, celebrate successes however small they are and think why you defaulted to tutorials instead of doing something, even thought you want to do something

Some depressed teens find their joy in life and just go on with their lifes. Some are still depressed and go on with their life’s, but are unhappy. I recommend the first option.

Bang.

Because I thought of a funny word first an then read the post til the end

Does your sword swing both ways?

Gigagram for everything. Just make it scientific for grams.

Yea this is 3,56e-6 Gigagram, I like my steak big.!

I am all in for Gg

So please give me an example of “building things” and why metric would not be better when measuring "small things*. Like I can measure anything in both units just fine, its whats the tool is telling me isn’t it? So it’s either about up/down scaling, which is just multiply by 10^x for the amount you need (aka slide the decimal point to where you need it)

Am I the only one who thinks cilantro and parsley taste like soap and its like fine but not pleasant?
