World's first bus using hydrogen under normal temperature and pressure rolls off in central China

[cirr]

I cannot verify unless i see the schematic, whatever it is. I know it is impossible to publish schematic

More details: http://www.gx211.com/news/2016920/n3878394570.html

Time to learn Chinese(for only a small body of Chinese scientific and technological progresses is reported in English) or have someone translate the above into English.

hydrogen fuel under normal pressure and temperature

very interesting and it is good accomplishment considering the technical difficulty.
So how do they produce the hydrogen in the first place that needs to be economical as well.

It's an interesting phenomenon.....
If a project has 5 phases, for the first 4 phases, all achievements are mostly published in Chinese.
When the project is finally done after phase 5, we publish English articles...
The rest of the world responds like, WTF.....Out of nothing!

Maybe you can open a chinese language forum here.
I wont mind learning @cirr

China's R&D is getting crazy now....
From some some unknown university....
@jkroo I bet u have seldom heard of this one....

Talking about which

Previously, the best material for H2 storage is N-ethylcarbazole, which has very nice features for H2 flow and H2 release. But the key disadvantage of this material is its high melting point, i.e. this material keeps in solid state under normal temperature. The ideal material should have low melting point, so it can be in liquid state under normal temperature, hence easy for transportation, e.g. transportation via pipe.

The key breakthrough done by the Chinese scientists is that they find better material with lower melting point (-20 degrees Celsius), while still keeping very nice H2 flow and release features.

Regarding the cooling fans you mentioned, my guess is (just my guess, may not be fully correct): we need to heat the H2-storage material (heat it to 100~200 degrees Celsius) to make the H2 released. The cooling fans are maybe prepared for this.

Below is the bio of a scientist that joining the project. The bio mentioned the low melting point of the new material his team developed: -20 degrees Celsius

Hope the answer helpful.

I can't believe the university where my father teaches has such scientists and researchers....
I thought it was crap.

It seems that they come out all of a sudden.

如雨后春笋。。。

diligent and smart people, plus strong and consecutive investment from the government, now we see the fruit!

Innovatian would lead China to worlds powerful country.
Way to go china.

What's the advantages of this bus, sorry?

 

[GS Zhou]

What's the advantages of this bus, sorry?

the conventional fuelcell bus has a high-pressure-resistant tank for H2 storage. And the H2 is kept under very low temperature. Very dangerous.

But the Wuhan-invented new bus can carry the H2 with normal pressure, and normal temperature. Much safer than the conventional design.

In addition, the "normal pressure, normal temperature" feature lowers the difficulty/investment requirement of H2 station (加氢站).

This is related to this thread. This investment will spur the development of hydrogen energy vehicles.
Money talks, bullsh*t walks.

China Motor City sets up fund developing hydrogen energy vehicles
(Xinhua) 16:37, September 22, 2016

WUHAN, Sept. 22 (Xinhua) -- Long positioned as China's Motor City, Wuhan, capital of central China's Hubei Province, has set up a fund to invest in the industry for the hydrogen energy automobiles of the future.

On Wednesday, the city government signed a deal with two top Chinese universities -- Tongji and China University of Geosciences -- to jointly set up a fund worth 200 million yuan (30 million U.S. dollars) in efforts to initiate the industry.

Wuhan is China's major auto production base, home to the Shanghai General Motors responsible for the Buick Excelle, the Dongfeng Renault plant, PSA, Honda and dozens of auto part-makers. The auto industry now supplies 20 percent of the city's industrial output and employs more than 1 million residents.

The government hopes the fund can obtain 10 billion yuan from the provincial fund for regional economic belt development, for clean energy auto development.

According to the deal, the government will encourage domestic auto makers to establish independent hydrogen vehicle brands.

This year trial production of prototype hydrogen-powered buses and logistic vehicles is expected.

Hydrogen fuel cells are a clean energy source used in the automobile industry. In 2015, China became the first country to utilize hydrogen-powered tram technology, with China South Rail's hydrogen-powered tram.

I'm going to buy a Jeep very soon !

sorry to hurt you guys in here

Made in Wuhan or Made in Changsha, I choose Made in Changsha!

Maybe my next car would be Citroen C6 made in Wuhan !

dy, dy, dy. You can choose Shenzhen this time.

@jkroo I bet u have seldom heard of this one....

This university have some good majors especially the mechanical and electrical engineering and just that. Ranked 168 in China.

Innovation is not totally based at rank should consider the people, R&D investment and environment. Another hint is that Changsha has a strong mechanical engineering industry.

Does Hydrogen fuelled cars and buses have anything over electric cars and buses? Any advantages?

If not, why would someone play with Hydrogen, a highly combustible gas, instead of using electricity.

To students in Wuhan, this university used be one of the many which you can enter even you close your eyes in the final exam.....But of course, it does not mean it's bad....One of my father's students is now Xinjiang's top 10 richest guy. And he owns a tourist site on the slope of Tianshan Mountains, which will be connected to Urumqi by low-speed maglev train (same one as in Changsha)
