This piece is just propaganda. One wonders what would be expected:
To date, it has received $281 million in taxpayer dollars via Department of Energy grants. According to the Department of Energy, it has stored more than 2.8 million metric tons of carbon dioxide since 2011.
This would place the cost of sequestration at... $100 tonne, which is pretty much the price that everyone else has estimated for carbon capture and sequestration, as discussed in articles like this. How much was sequestration of 2.8 million tonnes of CO2 supposed to cost?
"Carbon capture project captures almost no carbon". Really? Because 2.8 megatonnes doesn't seem like "no carbon" to me. Was it that "it only caught 10% of the carbon produced on the site"? Well then, maybe it should have been $2.8B of taxpayer dollars to capture 28 MTCO₂. What would the headline have been then? "Carbon capture project costs taxpayer $2.8B for almost no carbon"?
I want the cost of sequestration to be lower just like anyone else, but doing nothing is a terrible strategy to learn how to reduce costs.
If you don't want taxpayers to pay for it, change the laws and make the price of carbon emissions >$100 tonne. Then ADM will have to pay their own sequestration costs. If you don't like sequestration because it's expensive, then what's the plan for decarbonizing the atmosphere and reducing global temperatures after emissions are zeroed out? If your plan for a carbon neutral world is "endure global warming for thousands of years until the carbon gets sequestered in soil", that's fine, but you can't blame people for wanting to see things get cleared up on the order of decades.
This project was a success, insofar as it accomplished what it set out to accomplish as a publicly funded demonstration of the technology. The fact that the site emitted other carbon that wasn't captured is irrelevant.
