My first question was... "What happens to the captured CO2?"

So I went to the link which in turn linked the researcher's technical paper.

The short answer to "where does the CO2 go" -- you have to PUT it somewhere (think geological formation), but if you do it right, it's a twofer! You can use it for enhanced oil and gas recovery techniques. From the paper:

"Although a typical destination of the captured CO2 is commonly envisioned to be some form of passive geologic storage or other storage type, this work is also motivated by a vision of utilizing the captured CO2 to displace valuable oil and coal-bed methane stranded in mature reservoirs, as illustrated in Figure 1, before storing it permanently in spent reservoirs. Such a CO2-driven displacement is referred to as enhanced oil recovery (EOR) and enhanced coal-bed methane recovery (ECBMR)."

But remember,
even if the replacement filter material were free,
and even if there were no cost to create and install the filters,
and even if there were no smokestack “excessive backpressure (lower efficiency to generate electricity!), and even if there were no storage disposal volume, energy, manpower, or transportation costs (or pipe line fees or pipe construction costs),
and even if there were no use for the CO2 that is now being released (because we ARE seeing 25% MORE plant and crop growth from the increase in CO2 ...)

There would still be NO reason to trap or separate the smokestack CO2.

AGW is socialist myth.

That was my first response too. Great answer.

This is remarkably good news. Carbon capture and sequestration at the source is identified as one of the 12 wedges that can be used to reduce civilizations carbon emissions.

The main unknown is the total sequestration capacity -- there's a wide range of estimates. But if this is truly commercially viable, this is an important advance.

Sweet...

I wonder if they could sequester the CO₂ and use it in "enhanced greenhouses" e.g. for plant growth. You know, like corn.

Cheers!
