China’s Mingyang unveils world-first 30MW pure hydrogen electricity generator

A 30MW pure hydrogen gas turbine unit can effectively solve the problem of power abandonment in wind and solar energy projects.

A China-based firm has achieved a groundbreaking feat by successfully igniting the world’s first 30MW-class pure hydrogen gas turbine.

Called Jupiter I, the gas turbine is jointly developed by the Mingyang Group and several other companies and scientific research teams.

The turbine, which offers a key solution for renewable energy storage, converts hydrogen from storage tanks back into electricity during peak hours.

Converting excess electricity into hydrogen for storage

The major challenge with renewable energy is the substantial waste that occurs during off-peak hours. Converting excess electricity into hydrogen for storage and then back to electricity at peak times is a viable solution, according to the company.

Wang Yongzhi, general manager of Mingyang Hydrogen Gas Turbine Technology, stated that using hydrogen for power generation achieves a carbon-free process known as power-to-hydrogen-back-to-power...more

[Think. Again.]

1. One of the beauties of Hydrogen is it's versatility...

....H2 can be used in fuel cells to produce electricity by combining it with Oxygen, or it can burned like diesel in combustion engines to run heavy vehicles or turbines that produce electricity or even heating.

All without emitting CO2.

And when the Hydrogen itself is produced using only non-fossil fuel processes (Green Hydrogen), the entire work cycle, from production to use as energy, is completely carbon free.

And, it can be easily stored for future use on-demand or transported to where the energy might be needed.

2. Hydrogen is nothing but a battery, but this is a good use for it.

It sucks that making hydrogen has a lot of energy loss, but when you have extra power for solar it makes sense to do something with it. You have to live with about a 20% loss, but its better than not producing and using the power when you can.

Too bad this is not easily scalable to small back ups distributed around. Imagine small tank farms and generators handling small cites in the event of power outages, or just local supplemental during high peak times.

3. A missing detail that I don't enjoy about the threads of green energy & meta-discussions about green energy overall

What happened with dynamos?
What happened with magnetos?
What happened with alternators?

Did magnets vanished or something?

Hydropower – we've exhausted the possibilities wherever it could have been done, now people are worrying about dams collapsing.

Aeropower – I think a lot more can be done but during specific seasons in different climates (ex. winter), they're dead.

Solarpower – This too still has more to cover, though I understand that – just like wind power – the maintenance side will be a doozy medium-to-long term.

[Geo]Thermopower – This can be done in specific areas on the globe and can only be harnessed if you drill for it, essentially. There is another method than conventional drilling nowadays but I'd reckon the NO1 concern will be about earthquakes that could close the tunnels deep underground, the shafts.


So back to my question, did permanent magnets vanished? Is the technology stuck and limited in output?

4. I am an electrician by trade.

Yes magnets still exist and they still have a use, but induction motors and generators are more controllable and powerful than perm magnet ones. Plus magnets need to be refined from minerals that need to be mined, and those minerals have other uses. Including batteries, the nickel and cobalt have better uses.

The problem with solar is it gets dark out side half the day. Wind is good if your in an area that has lots of wind, and lots of land that nobody cares about. And yes the long term maintance of wind turbines is huge, and the end of life problems are even bigger.

Nuke power is really the answer, but first we need to leave the treaty that says we can not use the nuke waste to power reactors. It can be done and it burns up a lot more of the waste.

5. Wait? They use hydrogen to make electricity and then generate electricity? I know the hydrogen scammers despise the...

...laws of thermodynamics, but branching into perpetual motion machines?

It's actually not surprising, since the whole purpose of the scam is to greenwash fossil fuels, which is, after all, the real source of hydrogen in China. The claim that it's made by electrolysis from so called "renewable energy" is bullshit, has always been bullshit, and will remain bullshit.

The paper cited below gives, in real numbers, just how dirty hydrogen is in terms of carbon dioxide emitted to make hydrogen in China.

Subsidizing Grid-Based Electrolytic Hydrogen Will Increase Greenhouse Gas Emissions in Coal Dominated Power Systems Liqun Peng, Yang Guo, Shangwei Liu, Gang He, and Denise L. Mauzerall Environmental Science & Technology 2024 58 (12), 5187-5195

The text is clear enough.

From the introductory text:

... Currently, nearly all hydrogen in China is either produced directly from fossil fuels (55% from coal gasification and 14% from steam methane reforming (SMR)) or as a byproduct of petroleum refining (28%), with only 1% coming from water electrolysis. (2) Producing 1 kg of coal- or SMR-based hydrogen emits roughly 19 and 10 kg of CO2, respectively. (3) In 2020, hydrogen production from fossil fuels in China emitted ∼322Tg of CO2, equivalent to 25% of total CO2 emissions from industrial processes, a number expected to rise with increasing hydrogen demand. (4) Industrial processes include production of nonmetallic mineral products, chemical, and metal products, as well as production and consumption of halocarbons and sulfur hexafluoride. (4)

6. A turbine ?? Why not fuel cells ?

Is there some special reason not to use a technology which is usually about 2x more efficient ??
