Coal prices vary, but can be as low as $50/ton. If you set the price for carbon burial much higher than that, it enables a business model you might not want to encourage.

You mean burning coal and capturing carbon back to profit from the price spread?

I think they mean digging up coal and burying it in the ground again. Carbon captured, mission accomplished!

The current spot price for a short ton of coal is $40 [1], if it stays this low for a while, and the subsidy is in fact above that price, then watch out for some "business model innovation" in this space.
