Xuzhou 3 Shows the Future of Subcritical Coal Power Is Sublime

Coal and nuclear are the only globally available and scalable base load electricity source.

Nuclear is too difficult and/or expensive at the moment ( moment=next 30 years perspective).

There is general consensus in the industry that coal will be the largest source of electricity in the next 60-80 years.

Lets get back to the question in 2080-2100 maybe the perspectives of coal would change at THAT moment.

Locally in rich or rich in hydrocarbons countries ( like US) natural gas is the solution.

But this is only locally ( the same as locally is the case with hydro and nuclear )

In general I would agree with this, although I'd say natural gas has base load potential in the US because it's so cheap.

New nuclear is expensive *at the moment*, but the reasons for that are more regulatory (Outdated designs = massive safety costs), financial (huge plant + long build time = massive interest costs), and political (on-site union labor is expensive). These issues would all be solved with modern, small, modular designs. Many such designs are in the works. Do you have any thoughts on these?

If any carbon capture tech becomes available, that doesn't require utilizing 20-30 percent of plant nameplate without it, that could be a savior for coal fired generation.

I don't see much promise of this in the foreseeable future. 

The Boundary Dam plant in Saskatchewan tried it.  It was a real technical and maintenance struggle, which I would expect. AND, they had a customer nearby for the gas.  I guess there's a handful of demo plants out there that I am unaware of.

Economically, it will require some sort of firm guarantee (and perhaps subsidies) from "someone" to move this along.

Realistically, ANY technology that aids a coal plant in operating more efficiently, or with fewer emissions will work better with a natural gas plant.  Worried about carbon emissions?  You have 1/2 as much to capture and dispose of with natural gas.  Worried about sulfur and volatiles emissions? Burn natural gas and your problem disappears.  Worried about ash and particulates? Burn natural gas and the problem disappears.  Have a better boiler, turbine, heat exchanger, superheater or condenser?  It will work with natural gas too.  The only benefit coal has is that it's cheap in places where it's close at hand.  That advantage has already been eliminated in places where natural gas is abundant, and the growth in LNG trade is steadily reducing the coal price advantage elsewhere.

So true.

And no pulverizers, bunkers, conveyors, or coal pile employees (and heavy equipment)  required.

And no ash erosion to deal with in the boiler.

Or ash disposal.

LOL, let's compare an extraordinarily expensive scientific research venture with burning coal.

Get NASA involved and tell me about how cheap and effective this process will be. 

The science is already there... the cost effectiveness is not; and never will be with so much natural gas around.

Obama did throw 4~5 billion at trying to clean up coal. It didn’t happen. A much larger number that didn’t work with Solyndra. That was 500 million. Notice the difference in the failures? Nobody remember Obama trying to save coal. 😂😳

It's not worth trying, because there is not any good reason to continue using coal at all - see my comment above about natural gas.  

[RichieRich216 + 454]

There is always a good reason to use basically an unlimited supply of energy within your own borders! China doesn’t have any and continue to open at least one new coal fire plant per month! It’s called Self Preservation! Why import energy when we have decades of fossil fuel within our borders! If China had such reserves they would be opening 100 coal fire plants per month! 
 

I am tired of the U.S. have to take the “Moral Highground” argument used in propaganda against our own people, Just like the falsehood in the 19 hundreds that people came to America for freedom, That’s 100% bullshit, They came because they were starving before, during and after WW1! Some French propagandist gives us the Statue of Liberty and all of a sudden the narrative was changed!

We would have been better if we stayed out of WW1 and WW2 and let the rest of the World go fuck themselfs! A DEMOCRAT drew use into WW2 because he cut off oil sales to Japan which left them no other options but to hit use, and the propaganda machine cranked up and push a patriotic duty to go save the world!

What did it get us other then Husbands and Son’s never coming home and we then rebuilt all our enemies and became the World’s policeman! 
 

This Country was blessed with everything it needed within its our borders to sustain itself yet we constantly get drawn by political parties and politicians to spend Trillions on every other Country!

2020 China produced 3.84 billion tons of coal......

China's 2020 coal output rises to highest since 2015, undermining climate pledges

BEIJING, Jan 18 (Reuters) - China's coal output rose last year to its highest since 2015, despite Beijing's climate change pledge to reduce consumption of the dirty fossil fuel and months of disruption at major coal mining hubs.

The world's biggest coal miner and consumer produced 3.84 billion tonnes of coal in 2020, data from the National Bureau of Statistics showed on Monday.

China's coal output dropped after reaching a peak of 3.97 billion tonnes in 2013, as Beijing axed excessive mining capacity and promoted clean energy consumption. But production is rising amid surging industrial demand and an unofficial restriction on coal imports aimed at shoring up the domestic mining industry.

 

For December alone, coal output was 351.89 million tonnes, up 3.2% from the same month last year, and up from 347.27 million tonnes in November.

nope - it's a short term effect.  There was a reduction of investment in natural gas production caused by Covid, which caused a reduction in supply.  Now that economies worldwide are recovering, there is a delay in the 'catchup' of supply.  This is an issue for supplies of just about everything right now, including coal, steel, oil, copper, and everything else. This is made particularly bad for Europe by the fact that they are engaged in a trade dispute with Russia who supplies 45% of the gas used on that continent.   A little extra coal will be burned in Europe this winter (not much extra, they can't get that either) and that will be the end of that.

There is no "trade dispute" with Russia, just "sanctions" and being jerks. A "little extra coal" can also only come from Russia.

That’s literally the definition of a trade dispute from the point of view of one of the parties involved. 
 

Europe can get coaL from many possible sources, but only a little bit from each, and often at great expense.  Except for metallurgical coal, which is too expensive and I’m too short a supply up burn for electricity there are no world markets for long distance coal trading.

Glad you see it that way! Only UNSC may apply international sanctions. Unilateral "sanctions" violate every conceivable WTO rule.

Also, almost complete. The only point you missed is that a lot of coal users depend on supply over rail and some on the river barges. Getting an ocean ship's full of coal into a major port might only get you part of the way.

For rail-transported coal, the market is usually cornered by Russian Kuzbass region. It's a region out in Siberia around Kemerovo. They do mine in open pit, which is enough to make even the Ukrainian and the Polish domestic mining operations unprofitable without subsidies. They've got metallurgical coal up the wazoo and lower grades, too. I think if you try to burn metallurgical coal in equipment not intended for it, you'll break it. So, it's not about the shortage. The coal guys have their traditional fallback fuel - old tires. Just when you though that coal was the dirtiest fuel there is. Lignite / peat burning plants can easily burn dried municipal sewage sludge, too.

The "Europellets" (EN+ wood pellets) are as good as best metallurgical anthracite or better (6% moisture, no ash vs. something like 8% moisture and 1% ash) Of course, making them is a bitch (because powdered wood that dry is a major explosive hazard) so it is also best outsourced to Russia. (In general, yet another sneaky plot to export a dangerous process generating much waste heat to the East and call it a renewable technology in the West. Europellets cost about 1/2 of the equivalent amount of heavy fuel oil in EU, give or take)

Biden had a mercy on Canadians. Theirs is the worse possible source of oil ROEI-wise. Trump was obviously after their subsidies.

There is absolutely no legal basis for US trying to regulate Northstream, a business between EU and Russia US is not a party to.

There is a tremendous amount of natural gas around the world. Pipelines and other infrastructure are needed for the distribution. Countries need to have the finances to gain that. Natural gas can replace a great deal of coal and should whenever possible. China has plenty of countries shipping piped natural gas and CNG to it. More pipelines and CNG plants are being built from Russia and Central Asia.
