LANL published a paper circa 2007 or 2008 on how to make carbon-neutral hdyrocarbon fuel using carbon in the air and the electricity and waste heat from a nuclear plant. According to the paper, it was competitive with oil-based gasoline at around $5/gallon. |

Its authors badly underestimated how much new American nuclear reactors would cost.
We performed economic analyses on a partially optimized baseline concept based on a single Gen III PWR to provide power for the process. The analyses estimated a capital cost of $5.0 billion for an 18,400 bbl/day synthetic-gasoline plant and $4.6 billion for a 5,000 tonne/day methanol plant. Nuclear power accounts for more than 50% of the total plant capital investment.
If just over 50% of that cost is supposed to be nuclear plant, it would be $2.5 billion for a Gen III pressurized water reactor. ($2.9 billion now, accounting for a decade of inflation.) The just-abandoned VC Summer project was supposed to build two new Gen III PWRs in South Carolina. They pulled the plug because estimated cost of completion had spiraled up to $25 billion ($12.5 billion per reactor).
