I have to wonder what is released when this synthetic fuel is used.

Robert get practical.

CO2 capture is already done at some coal power stations and buried underground but it is expensive to do and this invention is a much cheaper way to do the same thing.

Well, the solar and windy farms are proving to be a bit like Tesla cars - kind of useless but they could be used to power CO2 capturing from the air as well as powering electrolyzers to produce hydrogen and oxygen from fresh or sea water as is already being done overseas.

As far as thorium goes, India is still trying after about 40 years. And the Yanks got it going but abandoned it for bomb production.

Chevron Gas produces lots of CO2 as they split it from natural gas and they are now burying it underground in sandstone.


Lee, CO2 capture is now easy and cheap. The synthetic fuel is probably oil or methane.

"1. CC. It is very expensive and technically difficult. There is today exactly one power plant in the world with partial CC, SaskPower’s Boundary Dam project in Canada, which began operation in the fall of 2014 at a CC only cost of $1.5 billion. The plan was to convert coal fired generating unit #3 to CC, capturing 800,000 metric tons of CO2 annually to sell for tertiary oil recovery in Saskatchewan’s nearby Weyburn oil field. For the two most recent complete years (2017-18) the average Unit 3 uptime was only 70% (severe maintenance problems), while the CC parasitic electrical load has run about 30% rather than the planned 25%. On July 10, 2018 SaskPower announced it would not be expanding CC to units 1 and 2 as originally planned."

Won't they be happy with this new invention then ?

That is kind of a Greeny denier site. It just says NO to everything just like the Greenies do.

I am hesitant to challenge the highly respected Lee. But this does seem to clash with his veracity.


There are currently 23 large-scale integrated CCS projects in operation or under construction. Significant projects include:

Boundary Dam power station
The world’s first large-scale CCS project in the power sector commenced operation in October 2014 at the Boundary Dam power station in Saskatchewan, Canada.

Petra Nova
Petra Nova, which came online in early 2017 and is the second CCUS coal plant, is the world's largest post-combustion carbon capture facility installed on an existing coal-fuelled power plant and plans to store more than 1.6 million tonnes of CO2 a year.

The Sleipner and Snøhvit CO2 storage projects
These projects in Norway have stored over 16 million tonnes of CO2 into offshore deep saline formations.

Abu Dhabi CCS Project
The project came online in 2016 and is the world’s first commercial CCUS facility for the steel industry, capturing 800,000 tonnes of CO2 and, injecting it in maturing fields to enhance oil recovery (EOR)

Tuticorin CCU Project
The unsubsidised, fully commercial CCUS project from Carbon Clean Solutions in the port of Tuticorin, India has been able to significantly reduce the costs associated with capturing the CO2

Ah but Bobby just so long as it doesn't leak out and/or create acid down there.

ClimeWorks also sells CO2 for soft drinks etc.

They have really got this CO2 sucking thing from the air down pat all right.

Firstly you were talking coal and CCS. Now it appears there may be a second one - Petra Nova. Which apparently is marginal operationally.

Are gas plants.

Abu Dabhi is taking CO2 from a steel smelter.

Tuticorin is taking the CO2 and making baking soda.

Has Lee forgot about the rest ?

"There are currently 23 large-scale integrated CCS projects in operation or under construction."

What about the rest ?

Most existing CO2 capture is expensive to operate and so the new tech could be very attractive for these sites if they can commercialize it.  Probably involves bubbling the CO2 thru their catalytic mixture.

One of the nice things about the new tech is you don't have to bury the CO2.

Exactly how many in operation and how many under construction?

Yes. And they say it is scaleable. The proof of the pudding would be in the eating.

And there is no need for it now. Increased CO2 is greening the planet. Making crops grow better.

"Globally, vegetation greening has occurred over a larger area than vegetation browning (high confidence)."

latest IPCC report Summary for Policymakers.


And increased CO2 greening the planet is improving natural plant sequestration.

Heavens Lee, are you a climate denier ?

CO2 capture is the next big thing after solar and wind farms.


Even Chevron Gas is burying CO2 underground after it splits the CO2 away from the natural gas.

...

https://qz.com/1684903/chevron-starts-gorgon-gas-project-that-buries-co2-undergr...


And there are a few more CCS systems operating

IS THE TECHNOLOGY PROVEN?

Yes. CCS is already being used successfully across the world. CO2 capture, transport and storage technologies are used in oil and gas sector projects in Canada (Weyburn-Midale) and Norway (Sleipner), where CO2 has been injected since 1996 and 2000 respectively.

Two coal sector CCS projects have commenced operation recently: Boundary Dam (Canada, 2014) and Petra Nova (USA, 2017).

CARBON CAPTURE AND STORAGE IN AUSTRALIA

There is big potential for CCS to be used commercially in Australia. When it commences CO2 injection, the Gorgon Project in Western Australia will be the largest project of its type in the world.

Other Australian projects have successfully demonstrated CCS technology: the Callide Oxyfuel project capturing CO2 at an operating power station in Queensland, and the CO2CRC injecting 65,000 tonnes of CO2 into a depleted gas field in Victoria’s Otway Ranges.

Scunge the warped loony Greeny is begging for some attention from her HERO.

As a Tesla Fan Girl she will be relieved that the very popular Toyota petrol hybrids have closed the door on the dangerous unsafe pollution spewing very inconvenient Tesla Toy Cars.

And the Toyota hybrid petrol cars are just the preparation for the final solution of Toyota Hydrogen Hybrid cars which will see the end of the rather useless electric toy cars just like a century ago.

Wonder how much a liter Hydrogen will cost ? Will it be subsidized like LPG was initially ?


yeh and where will you buy the hydrogen from socko ? I bet you you'll be praying that there is a fool bowser down the road from you and not in another state Cheesy LOL

All battery electrical vehicle owners will enjoy free chargeups at home from rooftop solar whilst socko and its retarded mates will be once again taking it up the arse at the hydrogen fool bowser thats if they ever build any which has been coming for the last half a century  Cheesy LOL

Juliar - we won't need carbon capture once Thorium gets going:

http://www.ozpolitic.com/forum/YaBB.pl?num=1519823686/135#147


60 Thorium reactors by 2025 in India -


that's in only 5 years

But Bobby I realize now you like to wander in fantasy - but nice beneficial fantasy.

I looked up lots of stuff and India is still trying to get their thorium going after about 40 years and instead have gone to uranium even tho they don't have much.

They need the US to tell them how to do it as the US got a thorium reactor going years ago but let it grow dust while they concentrated on bombs.

Thorium has taken a backseat to uranium because of bombs and so thorium has not been developed to practical designs and won't be for many years as it is just too hard.

Even China has put them on the back burner.

Thorium just can't get a go

CO2 emissions
There are lots of manufacturing processes that pour out CO2 especially heating processes and electricity has only a minor role in this as the heat is provided by gas or coal.

Consider the Chevron Gorgon natural gas project where the natural gas is mixed with lots of CO2 which was until recently exhausted to the air but is now being buried in sandstone.

Lots of CO2 coming out here
