Those have existed for a long time. CO2 capture systems are the newest thing, but of course they are unfunded. Only a few plants have been retrofitted with them in the US.
Uh, that's a refinery, not a power plant. Without even looking at the description of the image you can tell its a refinery by the holding tanks and the almost 2 dozen separating towers within the image.
If these eco types were truly concerned about the environment, they would focus on scrubbers that break down the exhaust into inert or reusable matter.
Then we can burn as much coal as we want and use the byproduct for another useful application.
If they were concerned about the environment, they wouldn't destroy beautiful landscapes with ugly windmills and service roads. If they cared one whit about wildlife, they wouldn't chop up hundreds of thousands of endangered raptors and other birds each year. Just like BLM, its all about money and control, using leftist rhetoric to harness the power of gullible useful idiots.
And the technology is there. Obama even said at one point that he had solutions "right off the shelf". They know. The Sierra Club opposes solid storage of carbon but that may have something to do with the use of biomass or other things to get the process to net zero. At the end of the day, scrubbing CO2 is a lot less hard on the planet than producing wind turbines and solar farms.
They kinda did that with 2008 era diesel engines. They were fitted with extra large EGR feed tubes and coolers, a large catalytic converter, a DPF, and an air intake heater with a variable vane turbocharger and variable intake.
Together it all catches 99% of the soot, produces 50% less nOX than traditional diesels, no carbon monoxide with the palladium catalytic converter, and has soot filter pressure differential sensors to sense when it needs to be cleaned, then puts the engine in "regen mode" where it injects diesel fuel between the engine cycles to dose fuel downstream to the catalytic converter that ignites it and heats up the soot filter so hot it burns the captured soot off as ash at 40+ MPH for about 35mins given or take
Yup, and engines from that era and on are nowhere near as reliable as the earlier engines, nor do they have the fuel economy. A 12v Cummins powered Ram 2500 can get 20 mpg and the engine will literally last a million miles. The regen cycle on the engines unfortunately equipped with them kills the turbo. You have to rip all of that junk off of them to make them reliable again.
In part. The original intent during the time the term came about was to capture carbon but that never happened. Environmentalists were against it because they wanted coal itself stopped so instead of having byproducts in solid or other form we still have it in the air. But fortunately the environmentalists have not blocked the cleaning up of other bad gases. And oddly enough they were very quickly bought off when we discovered that VW had been pumping tons of that stuff into the air for decades but hid it from regulators.
Yes and no. It can also refer to the grade of coal. Clean coal having few contaminants in the fuel itself. But the most often used terminology is indeed in the systems and filters that clean the fumes created by burning coal.
Most gas turbines, unless they are peaker plants, are a combined cycle plant, which is a gas turbine combined with a HRSG and steam turbine.
Coal plants use steam, CC plants use steam, nuke plants use steam, even CSP solar plants use steam. Everything but hydro, PV solar, and wind turbines use steam.
Yep, steam drives the turbine to spin, then the kinetic energy from the turbine is converted into electricity through movement in a magnetic field. That's how electricity is generated. Whatever power source you use, the purpose is always the same, which is to boil water and create steam.
Not to get too enginerdy on you (because from an engineering perspective, you are 100% correct) but some of the other reasons water is used is because of its massive capacity to "store" heat as both its heat capacity and phase change. It also is only moderately corrosive in an oxidizing environment, is non-toxic and ubiquitous on Earth.
All-in-all, water is an amazing molecule and most leftists don't understand that the majority of their electricity comes from a system that is very similar to the first steam locomotives and Aeolipile.
Pretty much all thermal power plants use steam as the working fluid, only places without gas turbines are super super rural.
No I meant that the filters on the fumes from coal plants basically cause them to emit H20 and inert gasses.
Shhh don't hurt the narrative with your mean facts.
Facts are racist!
The green energy lobby has Democrats in its pockets..
These companies spend millions of dollars bribing Democrats to give them Federal money which they then funl back to the Democratic politicians
Under that in Texas 21 people died.. green energy killed peopl
Coal Scrubber is the word you're looking for.
Those have existed for a long time. CO2 capture systems are the newest thing, but of course they are unfunded. Only a few plants have been retrofitted with them in the US.
Heres one in Norway
That's weird, I have multiple CO2 capture systems in my yard, and they've been here for decades. Best part is, in the fall, they make apples.
Uh, that's a refinery, not a power plant. Without even looking at the description of the image you can tell its a refinery by the holding tanks and the almost 2 dozen separating towers within the image.
This is what a gas turbine power plant looks like - one of the newer ones
Don't worry, our lord and savior William Gates is already funding carbon capture.
Knowing liberals they probably think that's a racial slur.

I am sad every time I drive out into West Texas. They have destroyed the beauty of our State.

coal gassification is what is needed. Turns coal into something similar to natural gas called "synth-gas.

If they were concerned about the environment and CO2, they would expand nuclear. If the future is electric cars and trucks, we need lots of power.
Is this what clean coal refers to?

Gas turbines don't use steam. Those are steam turbines. Gas turbines use combustion gasses.
Correct in the most technical sense!
Most gas turbines, unless they are peaker plants, are a combined cycle plant, which is a gas turbine combined with a HRSG and steam turbine.
Coal plants use steam, CC plants use steam, nuke plants use steam, even CSP solar plants use steam. Everything but hydro, PV solar, and wind turbines use steam.
