This would be great for utilities, who could keep stranded carbon burning assets for their operational lifetime.

Although the carbon emissions would be net neutral, Such a system would not be greenhouse gas neutral. Some methane from the natural gas plants will leak out. This is a gas that is 25 times more potent than CO2 over a 100 year timeframe [1].

Nitrous oxide, which is a byproduct of the combustion process, will be emitted and this gas is 298 times as potent as CO2 over a 100 year timeframe.

Ammonia is injected into gas turbines to scavenge nitrogen to prevent NOx production.

This is a solved problem. Please do not engage in idle, misinformed concern-trolling.

I assume you’re talking about Selective Catalytic Reduction. Although you can reduce the amount of NOx from emissions using SCR, you cannot eliminate it. I would not call it a solved problem so much as a mitigated problem. Furthermore, with catalytic reactions involving ammonia, depending on ratios of ammonia vs the emitted NOx gas, and the age and quality of the catalyst used, you may see slippage, which is the injection of too much ammonia, which results in its release into the atmosphere. This too can result in the creation of NO2. Constant monitoring of the emitted gasses and maintenance is required.

Point here being that you could avoid this whole class of problem with energy storage technology. Although Lithium Ion batteries present their own technical issues to solve, there are other energy storage technologies that show promise [1].

Regarding your comment, you took a leap in assuming this was assuming it was idle, misinformed concern-trolling. It could be that I am ignorant of the NOx scavenging, it could be that I am aware of it and take issue with it. Both possibilities you ignored.

Please review the HN guidelines, you may find this passage relevant,

Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith.
