Each coal conversion facility and any carbon dioxide capture system located at the coal conversion facility, and any equipment directly used for secure geologic storage of carbon dioxide or enhanced recovery of oil or natural gas must be classified as personal property and is exempt from all ad valorem taxes except for taxes on the land on which the facility, capture system, or equipment is located. The exemption provided by this section may not be interpreted to apply to tangible personal property incorporated as a component part of a carbon dioxide pipeline but this restriction does not affect eligibility of such a pipeline for the exemption under section 57-06-17.1. The taxes imposed by this chapter are in lieu of ad valorem taxes on the property so classified as personal property.
