United States Patent Application: 0090235587
We've dwelled to some extent lately on the Carbon Dioxide recycling technologies being developed by scientists at our United States Department of Energy's Idaho National Laboratory.
Our reports have included: USDOE Idaho Lab Recycles More CO2 | Research & Development | News; wherein is detailed "High Temperature H2O/CO2 Co-electrolysis; G. Hawkes, J. O'Brien, C. Stoots, et. al., and: USDOE Converts More CO2 to Hydrocarbon Syngas | Research & Development | News; which of which revealed that USDOE scientist Carl Stoots, as above, was named as the lead inventor of a Carbon Dioxide recycling technology in: United States Patent Application: 0080023338 - "Electrolysis for Syngas Production"; which formally disclosed some of the Carbon Dioxide-Water co-electrolysis procedures, for the production of hydrocarbon synthesis gas, that had been developed, as evidenced in our other reports, at the Idaho Lab.
Herein, via the initial link in this dispatch, we see that another of the Idaho Lab scientists, named above, has been identified as the lead inventor in yet another Carbon Dioxide-recycling technology originating at our Idaho facility.

We have documented to, we're certain, the point of tedium the multitudinous Coal liquefaction and conversion technologies that were developed, over multiple decades, by the various companies which at last coalesced into that lovable giant, ExxonMobil.
But, herein is yet another; albeit one with a delightful twist for those who object that CoalTL is too costly.
Esso themselves say that all the improvements in Coal liquefaction science they disclose and catalog herein "make the economics of the process appear attractive".
Moreover, as you will see via an additional reference appended, their improvements also likely prevent the release of any Carbon Dioxide.

Information Bridge: DOE Scientific and Technical Information - - Document #973340
In this report, we see that our United States Department of Energy, through our Sandia National Laboratory, in New Mexico, contracted and worked with a team of collaborating and visiting scholars from the University of Wisconsin, to, as they put it, establish the "fundamentals of synthetic conversion of CO2 to simple hydrocarbon fuels".

The better part of a year ago, we sent you a report, now accessible via:
Exxon 1982 Hydrogenated Syngas from Carbon & Steam | Research & Development | News;
wherein was disclosed details of: "United States Patent: 4331529 - - Fluid Coking and Gasification Process; 1982; Assignee: Exxon"; a technology that, starting with a "charge stock" which "comprises coal", used two sequential gasification zones, to, "in the presence of steam" convert, first, the raw Coal, and, then, the carbonaceous residues left by the initial Coal gasification into "a gas comprising hydrogen and carbon monoxide, which is suitable, after conventional shift and clean up, for use as synthesis gas".
That technology, which utilizes Steam to sequentially gasify and hydrogenate both raw Coal and the carbon residues left by the initial Coal gasification, was, it seems, based on, or at least related to, an earlier Exxon technology, developed by another Exxon Coal scientist we have previously cited; a technology which was focused primarily on the use of Steam gasification to extract hydrocarbon values only from the carbonaceous residues generated by a different sort of, more direct, Coal liquefaction process.
