Iceland power plant stops greenhouse gas by turning carbon dioxide into rock

Subscribe to our YouTube channel for free here:

A geothermal plant in Iceland has developed technology that turns carbon dioxide into rock. Sitting at the foot of an active volcano, the power station uses a process called direct air capture to suck CO2 from the atmosphere. The procedure mimics the natural process of storing carbon into the ground that would take hundreds of thousands of years to complete. The innovation is seen as a way of removing CO2, a major component of greenhouse gas, from the atmosphere to tackle global warming. But the technique is still in its infancy and is costly as it involves using large amounts of energy.

Cool we just need 10.8 billion of these to reach net 0 carbon dioxide.

[Miltiades]

Let's hope this technique gets used further

[themans]

Seriously everyone who says America is the greatest country needs to get their eyes checked, top 5 at best

[sheridan]

I see your rocks, and I raise you "plants"

[williamngo]

This is not scalable. Not many countries have geothermal energy available to them. However every bit helps. Great work

[priskadwi]

You can make a handmade jewellery from it

[IluvTama]

Dude just woke up and the first thing it comes to his mind was
"maybe I should start making gas turn into a solid material"

[ltnxysu]

This is what kind of trees do, when they bind the carbon with sugar to make wood.

[guiltyzx]

Excellent usage of a locally abundant resource... now if we could only find that abundantly elsewhere, to make it economically viable or something. Need more development, but amazing start. Only for 2 years though...

[openlink]

man, this guy is a true "stoner"

[Mike-knge]

I guess that problem of "running out of sand" is no more

[fahadus]

Those comparing this to trees. A grown tree is carbon neutral, while a growing tree is meaningfully carbon negative. Also, as the tech matures, it will become cheaper and more efficient. Down the line, this might be a game changer. While a forest you plant now will have plateaued in about 15-25 years. So by all means, plant trees, lots of them! And also keep developing new methods.

So... how many million tons of CO2 annually is getting turned into a rock by their benefactors? I mean, you're presenting it as a serious tech that is solving a problem, not as a exhibit prototype needed to lobby for more relaxed rules on oil drilling, right? Right? Who's the sponsor btw?

[erTurbo]

If we say we produce 40 billion tones of CO2 annually, we would need around 11 million devices like this to get carbon neutral

[Budget_Asian_family_traveller]

When I was in high school stage, I used to dream about solidifying the exhaust gases of IC engine vehicles with some sort of addon devices at the end of exhaust system, so that the solid slabs formed can be dumped later on. I thought this would be comparatively lesser polluting the nature than the one in gaseous form. The addon system should have a storage container to hold the solidified deposits upto to certain weight and once it's filled, it has to indicate the user so that the user will manually dump the solid wastes into specifically designated garbage boxes to be kept in all main public areas / in fuel stations

[SubmittedtoAllah]

I have several factory in my backyard which also captures CO2. Much cheaper. It's called Tree.

[seanlee]

There are a lot of scientific methods out there to convert CO2 into something as well as plastics and rubbers. But the biggest issue is making it economically viable and sustainable. People in general aren't willing to throw money into something unless they get a return or unless it's charity, and if they're going the charity route, very difficult to get stable funding or enough funding at all.
I think the real solution is making an economy out of the CO2 conservation or conversion

[yudistiraliem]

Rather than capturing from air I believe this could be modified to capture CO2 stright from exhaust pipe or chimneys which has much higher Co2 concentration

[genesisleo]

for now they r just able to solidify it into rocks i bet soon there wil be some way where these rocks with Co2 will be used as some form of fuel/energy for something looking so forward to it
