It mentions that there is a plant under construction in Kemper County, Mississippi, that should capture more than half of its CO2 emissions and redirect them to an oil field.

One of the units at Saskpower's Boundary Dam plant up here just finished being converted to carbon capture and is operating now. It supposedly captures 90% of CO2 emissions.

Not necessarily. It depends on which part of the 5-way alliance that forms current American conservatism we're talking about.

You've got the business conservatives who seek low taxes and low regulation, the foreign policy hawks who seek a strong defense budget, the social conservatives who fear moral anarchy, the racists and nativists worried about immigration and affirmative action, and the elderly retirees who rely on Social Security and Medicare.

They are doing some funny math to claim 80% efficiency, as that is almost double the current best efficiency achieved in a lab: https://en.wikipedia.org/wiki/...

And I'm pretty sure 80% efficiency is above the theoretical maximum too . . . .

Nothing funny about it. This thing is combined heat and power system. You get electricity directly from the cells, and in keeping the cells cool, you get hot water suitable for running an absorption chiller and desalinating.

its just a simple idea I have always considered; loading electrical energy into physical potential energy by way of working against gravity. Maybe, instead, just run a big heavy chunk of metal up a notched pole? Then release it to spin a worm gear, to a large cog, then big generator as it slowly drops?

You'd still have the exact same issue with the amount of mass and/or height needed. Mass x height x 9.8m/s^2. For a kilowatt-hour of storage, mass x height needs to equal about 600,000. Gravity-based energy storage simply requires a lot of both for any worthwhile amount of energy.

Banks of batteries are expensive and take up a lot of space. You'd need to provide several megawatts for several hours. That would require hundreds of 85kWh car battery packs.

And they'll be producing several hundred thousand such packs annually once the factory is operational.

Also, it's going to be a 10 million square-foot facility, with a few hundred more empty acres around it. I don't think they'll be pressed for space.
