The stated product profile looks like a carbohydrate (like cellulose) feedstock, I once managed such a plant where we installed process equipment to recover-purify-liquefy the carbon dioxide for sales to the Food and Chemical Industries. Because carbon dioxide (CO2) gas is a freely available resource, there are concerted efforts worldwide to convert this molecule into a chemical feedstock. The process could also be a proof of concept using methane as a model feedstock molecule to manufacture reagents suitable for consumer liquid fuels. But the use of biomass for energy generation combined with carbon capture and storage is less costly than chemical options, as long as sufficient biomass feedstock is available, the scientists point out. But the process also would produce a carbon-negative super-green fuel or chemical feedstock in the form of hydrogen. The Lux report also analyzed the use of municipal solid waste and waste gases such as carbon dioxide and flue gas as potential feedstock sources. Most previously described chemical methods of atmospheric carbon dioxide capture and storage are costly, using thermal/mechanical procedures to concentrate molecular CO2 from the air while recycling reagents, a process that is cumbersome, inefficient and expensive.

It uses the chemical process discovered by French Nobel laureate and chemist Paul Sabatier, who found that elevated temperatures and pressures could turn hydrogen and carbon dioxide into methane and water. It's too bad, too, as the chemical industry has actually been one of the better industries from an emissions perspective. The team demonstrated or carbonate," says Rau. "We not only found a way to remove and store carbon dioxide from the atmosphere while producing valuable H2, we also suggest that we can help save marine ecosystems with this new technique," says Greg Rau, a visiting scientist at Lawrence Livermore and senior scientist at UC Santa Cruz.
