China reporting that China is doing great... Call me Mr. Skeptical.

[–] [email protected] 3 points 1 year ago

So, what are the numbers reported by other parties?

Yeah, better go read some US propaganda against their peer competitor for some real facts about China. 😂

Who said anything about America? Fuck America. You know, most countries don't brainwash their citizens with China-level nationalism.

From your own article 😂

China is the largest producer and consumer of hydrogen globally, but less than 0.1 percent of the hydrogen it produces comes from renewable energy sources.

[–] [email protected] 5 points 1 year ago* (last edited 1 year ago) (4 children)

It can both currently produce only 0.1% of hydrogen using a green process, while also developing a new process that is 99.9% green (for the hydrogren that it produces using the new process). That means the overall production right now is probably still ~0.1% green, but the point of the article seems to be that they hope to transition to this new process, which sounds pretty cool.

And to also knock out a few other misunderstandings, I'll also address your comment below: The stats you link are for the number of plants, not the volume of production or consumption (what is claimed). Both stats can be correct if China has large plants that produce more volume than in other countries. But better yet, we don't even have to root around for the details - the article cites it's source: the World Economic Forum's latest whitepaper (June 27, 2023), which in turn cites statistica "Global Hydrogen Consumption By Country". So there you have it - China out-consumes hydrogen at a rate of about 2-times that of the next largest consumer (the United States). That seems to track pretty well, since both countries are similarly developed, and China is about 4x the size of the US by population. If you wanted to split hairs, you could say that this doesn't include volume of production. Given the incredible lead in consumption volume, I'm willing to grant them that omission.

And, not chalking this up to you, but I've seen other replies in here about how China is somehow cooking the books. That's becoming more and more obviously wrong (and more than a bit racist). As one indicator, their universities occupy 8 of the top 20 institutions in the Nature index. For those unaware, this is a premier British-based peer-reviewed journal that releases a ranking of academic institutions based on their publishing to high-impact journals. China's year-over-year change also means that they're rising on that list rapidly.

Or there is a middle ground where you'll actually get a nuanced take?

I'm mostly curious about what they're going to do with the hydrogen. Fuel cells? No hydrogen tech I know off has really proven scalable, reliable and cost effective. And while hydrogen generation was part of the issue it wasn't the biggest one. I'm also keen to understand if they use fresh water or salt water. The latter then there is potential for a energy neutral or positive even desalination process which would be massive for large swaths of Africa.

They've been using it for stuff like buses increasingly https://www.insidethegames.biz/articles/1132385/beijing-2022-hydrogen-buses

Another good use is in combination with wind and solar where you can produce hydrogen when there's energy available, and then use it to provide a steady energy supply. This addresses one of the main issues with renewables.

It's also just a good idea to try out a lot of things and see what sticks. We never know what might turn out to have an unexpected application in one niche. Global warming requires "all of the above" strategy. That will mean some efforts fail to produce results, but that's okay. We don't have the time to dawdle.

They don't have many buses like that yet and buses are always near population centers where using food waste to make biogas is simply much better in almost every way.

As for storing excess energy sure if we're talking solar generation but they use a lot of hydrogen too for this project and in that case pumping water up to the dam is a much easier and probably more efficient than generating hydrogen and either using it to run an engine or store in fuel cells. Fuel cells aren't all that efficient. Overall a lot of money spent that will not at all pay for itself for that use case.

I really struggle with why they've gone so heavily into generating hydrogen when there is a big lack of viable use cases. Though they're far from alone in overestimating hydrogen, BMW and Toyota both invested heavily in fuel cell research (and BMW experimented with direct hydrogen use) and neither came out the other end a winner.

Well from reading the article like a big boy I've learned that it's pure freshwater they use which is expected but lame.

As for what they're going to use it for that remains mostly a mystery. The world total for hydrogen fuel cell cars is 67,000 which is virtually nil and China aims for 50,000 of their own by 2025 which is also virtually nil. For reference they had estimated around 300 million cars 2021 and that number is on a rapid growth. 50,000 is less than 0,02%...

Further a hydrogen pipeline is not something I'd like to live near, I get it must exist for hydrogen tech to work but china + hydrogen pipeline is just a headline waiting to be written.

Personally I think they're betting on the wrong horse
