If you want to capture the CO2 from fossil fuel, it feels like it’d be easier to filter it out before dumping it in the atmosphere in the first place (apart from the obvious option of just not using fossil fuel)
Is that using numbers for carbon capture from the atmosphere? Carbon capture directly on the exhaust of a fossil fuel power plant would probably be an order of magnitude more efficient. Obviously you can’t sustain everything by only using fuel combustion, but you could probably reduce to total emissions per kWh quite a bit without even looking at renewables.

It would, but it takes more energy that gets produced total. You’re spending 300wKh to make 220kWh of electricity.
