Efficient carbon capture...

They have a way now to convert CO2 to solid carbon, efficiently.

Co-lead researcher Associate Professor Torben Daeneke said, “The work built on an earlier experimental approach that used liquid metals as a catalyst.”

“Our new method still harnesses the power of liquid metals, but the design has been modified for smoother integration into standard industrial processes.”

“As well as being simpler to scale up, the new tech is radically more efficient and can break down CO2 to carbon in an instant.”

“We hope this could be a significant new tool in the push towards decarbonization, to help industries and governments deliver on their climate commitments and bring us radically closer to net zero.”

I don't have access to the article, but based on the abstract, the metal in question is a gallium/indium alloy, which means the raw ingredients are expensive. And the liberated oxygen forms gallium oxide, which means you'll have to go back and reprocess that back to gallium if you want to do this at any sort of scale. I don't know how energetically costly that is, but it's safe to bet that it's not free. So, I'm a bit skeptical that this is the solution to all our problems.

Once we start having a consistent oversupply of electricity due to solar, maybe it'll make sense. But I'd need to know more about gallium oxide than I do in order to say anything more.

Can't find the full paper even through some of my Chinese sources (the translations of which are generally not of high quality), but here is another article: Decarbonization tech instantly converts carbon dioxide to solid carbon

We already have something that converts CO2 into a solid:

Trees.

Well, neat! It looks like the product of solid carbon is useful:

ABR Project Director David Ngo said the RMIT process turns a waste product into a core ingredient in the next generation of cement blends. ... "Ideally the carbon we make could be turned into a value-added product, contributing to the circular economy and enabling the CCS technology to pay for itself over time," Daeneke said.

So that would help address TheLurch's objection that the process is not free.

Yes, and reforestation can be a part of the solution, every contribution helps.

And the "carbon" the trees produce (wood) is useful for building things.

Given the soaring price of lumber, a needed commodity.

Yes, and if you had a few spare continents we could grow trees on, that would solve the problem.

Trees are an important contribution, but nowhere near a solution. Carbon capture with a low energetic cost will almost certainly be needed as well.
