World's first commercial sCO2 power generator begins operation in China

全球首台商用超临界二氧化碳发电机组在中国正式投运

The world's first commercial supercritical carbon dioxde power generator has begun operation in Southwest China's Guizhou Province. It is viewed as a milestone in changing the power generation mode relying on steam for more than a century. China calls the project "Chaotan-1."

全球首台商用超临界二氧化碳发电机组，已在中国西南部的贵州省正式投运。 这一成果被视为里程碑，标志着延续了一个多世纪、依赖蒸汽的发电模式迎来变革。该项目被命名为 “超碳一号”

以下是各国网友的评论：

Damn, what an achievement.. congrats

好家伙，这真是了不起的成就！祝贺祝贺

sCO2 technology may be a game changer. All my career working with power plants one fact sticking out like a sore thumb and that is the 1/3 efficiency of turbines. Even today a gas or steam turbine typically has an efficiency of just 1/3. This is to say we burn 300% fuel just to get 100% electricity out! The rest is wasted in the form of heat dumped into the environment, mostly as heated seawater back to the sea. For this reason no power plant can exceed 7,000 MW to 8,000MW barrier because the scale of abstracting cold seawater and disperse the heated seawater, normally with about 6 degree above the ambient, is at its limit. When a large plume of warn seawater circulates it can re-enter back into the cooling system to degrade the power generation. Using sCO2 instead of steam if fully implemented will definitely a game changer as the system does not need a massive amount of water.

超临界二氧化碳技术绝对能改变游戏规则。我这辈子都在和发电厂打交道，有个问题一直特别扎眼，那就是涡轮机的效率只有三分之一。就算到了现在，燃气轮机也好、蒸汽轮机也罢，效率基本都还是三分之一。说白了，我们要烧掉三倍的燃料，才能发出来一倍的电！剩下的能量全以热能形式浪费了，大多是把加热后的海水排回大海。正因为这个，发电厂的装机容量才突破不了7000到8000兆瓦的瓶颈——抽取冷水、排放温水（一般比环境水温高6度左右）的规模已经到顶了。要是一大股温水回流，重新进入冷却系统，发电效率就会下降。如果全面用超临界二氧化碳取代蒸汽，那绝对是颠覆性的，因为这套系统根本不需要大量用水。

they video states they hope to increase the efficiency by 50%. Although that is remarkable progress, based on what you've stated, it seems there will still be room for improving the efficiency. 1/3 means the efficiency was about 33%, which means with this approach they expect around 48-49%.

他们希望把效率提升50%。这进步确实很显著，但按你说的来看，效率提升的空间应该还没到头。三分之一的效率差不多就是33%，这么算的话，用这个技术应该能把效率提到48%到49%左右。

Claps are in order indeed

确实值得鼓掌喝彩！

it's insane that after all this time, we are still using boiling water into steam to create electricity. Even if we've achieved useful nuclear fusion reactors, they were supposed to generate electricity via boiled water into gas turbine. It was about time to make an advance in this field. Well done.

简直离谱，这么多年过去了，我们居然还在靠烧水煮蒸汽来发电。就算将来核聚变反应堆能投入实用，居然还是要靠煮水驱动燃气轮机发电。这个领域早就该有突破了，干得漂亮！

Fluidity of gas, density of liquids - Wow that's interesting!

兼具气体的流动性和液体的密度——哇，这也太有意思了！

Remember that ancient Chinese discovered steam,and they used it to cook domain buns etc... moxbustion, was a Chinese TCM who also adopts the same method.

要知道，古代中国人早就发现蒸汽了，还用它来蒸点心之类的。中医里的艾灸，用的也是类似的热原理。

Supercritical CO2 can now increasingly be used as heat transfer medium in power plants in place of steam. Jai Hind

超临界二氧化碳现在越来越多地能取代蒸汽，用作发电厂的传热介质了。印度必胜！

muhammadsyahrani8858
No need steam medium anymore

再也不需要蒸汽这个介质啦

EmptyCrystal
Cool. Now i wonder what other mediums could be used for thermoelectric conversion

太酷了。现在我很好奇，还有哪些介质能用来进行热电转换。

Check out thermoaccoustic device using stirling engine

可以了解下用斯特林发动机的热声装置

求你别说了

by here japan talk there own mind over taiwan but back fire on japan thru..... 100% usa would stand all th way(john mearsheimer say china cnt let japan get away with it(he say japan will use every thing they got on china(he thru.... china wouldve hit japan hard but will be war between china/japan

日本在台湾问题上胡说八道，最后肯定会引火烧身，美国百分百会全程撑腰（约翰·米尔斯海默说，中国绝不会放过日本。他还说日本会豁出一切对付中国，他认为中国会狠狠反击日本，但这样一来，中日之间就会爆发战争）。

Many techs / ideas came from the West but given up half way. China study them/ research and made them into fruitation.

很多技术和想法都源自西方，但他们都半途而废了。中国把这些技术和想法捡过来研究，最终把它们变成了现实。

MarcosCapixaba
This is the same as telling people the West is Older than China and India... In the past 20 years the number of inventions from China are more than the rest of the world combined. And you ignored every single trustful data to make that 5 years old emotional statement without any backing

你这说法，就跟说西方比中印两国历史更悠久一样离谱。过去20年，中国的发明数量比世界其他国家加起来都多。你却无视所有可靠数据，说出这种毫无根据、跟五岁小孩赌气一样的话。

Western propaganda has misled your brain. You need a reset

西方的宣传已经把你的脑子洗坏了，你得重启一下。

China is alittle late to the party because the USA was the first and is useing the power in texas as of 2021

中国这趟车还是晚了点，因为美国才是第一个搞出来的，2021年就在得克萨斯州用上这种发电技术了。

sweetchristmas101
The plant in Texas started construction in 2021; the actual testing only started in 2024. It is just a pilot program to test new technologies. China's plant is generating power and adding it to the grid.

得州的那个电厂2021年才动工，2024年才开始实际测试，只是个测试新技术的试点项目。中国的这个可是已经在发电，而且并入电网了。

Don't you see the headline? The world first commercial sCO2 power generator

你没看标题吗？这可是全球首台商用超临界二氧化碳发电机组。

masterkoi29
Hahaha... Are you nuts??? China was the first to use steam in cooking Chinese dimsum. When the western missionaries visit China's Qing dynasty,those missionaries copy China's way of cooking. All families in china have their own food steamer and the process of sCO2 was using steaming method.

哈哈哈，你疯了吧？！中国才是最早把蒸汽用在蒸点心上的国家。清朝的时候，西方传教士来中国，都是照搬我们的烹饪方法。中国家家户户都有蒸锅，而超临界二氧化碳技术用的就是类似蒸汽加热的原理。
