Herein is more information, from the USDOE's Idaho National Laboratory, concerning "Syntrolysis"; wherein Carbon Dioxide and Water are "co-electrolyzed" to generate a synthesis gas, composed of Hydrogen and Carbon Monoxide, well-suited suited for catalytic condensation via, for instance, the Fischer-Tropsch process, into liquid hydrocarbon fuels.
Before presenting our excerpts from the enclosed link and attached file, we want to explain that, if any of our readers have been interested enough to follow up with research of their own, they would likely have found the USDOE's Syntrolysis technology publicly associated most often with the conversion of biomass into liquid hydrocarbons, as a way to utilize the CO2 and the Steam that is produced by the gasification of biomass.
Don't be misdirected or misled.
Via separate dispatch yesterday, concerning the conversion of "Biomass and Coal into Liquid Fuel with CO2 Capture", from the USDOE's Savannah River National Laboratory, we documented that the United States Department of Energy does, in fact, consider Coal to be a type of "biomass".
In any case, following, with some comment appended, are excerpts from the enclosed link and attached document, further explaining that Carbon Dioxide, no matter where we get it, can be effectively recycled in the synthesis of valuable hydrocarbons:
"Co-Electrolysis of H2O and CO2 for Syngas Production
2006 Fuel Cell Seminar; November, 2006
Carl M. Stoots, Idaho National Laboratory, US Department of Energy
Abstract: Worldwide, the demand for light hydrocarbon fuels like gasoline and diesel is increasing.
(With the current) price of oil ... synthetically derived hydrocarbon fuels have become economical.
(A) research project is underway at the Idaho National Laboratory to investigate the feasibility of producing syngas by simultaneously electrolyzing steam and carbon dioxide ... .
The syngas can then be used for synthetic fuel production.
In spite of the greater complexity of co-electrolysis versus electrolyzing steam and CO2 separately, there are inherent advantages to co-electrolysis for syngas production.
Future research plans include ... long duration co-electrolysis tests ... ."

That was reported four years ago, and, presuming you to have followed our posts, you know that additional research and development proceeded, and that the technology was even given a name: "Syntrolysis".
In essence, we learn herein from our own United States Government, that, "since demand for light hydrocarbon fuels like gasoline and diesel is increasing" and, since the "price of oil (has made) synthetically derived hydrocarbon fuels ... economical", it is worthwhile, not to mention being, as implied, technically feasible, to produce "syngas by simultaneously electrolyzing steam and carbon dioxide", which "syngas can then be used for synthetic fuel production".
