Though the work is ongoing, Olah and Prakash hope to find a low-cost/low-energy method of turning the captured carbon dioxide into methanol - which can be burned as a fuel source and used as a chemical feed-stock. "We can take carbon dioxide directly from the atmosphere and turn it into useful products like fuels and chemicals without having to go through the inefficient process of growing plants and extracting sugars from biomass." The process is made possible by a Other researchers in the program are avoiding hydrogen by feeding energy as electrons directly to the cell, or using electrochemically generated formate as feedstock. The modified bacteria are highly efficient to set up colonies near to industrial plants. And chemistry is playing its role in exploring how CO2 may be used as a chemical feedstock to make a range of useful materials and products. This would allow greenhouse gases to be recycled into useful chemical feedstock – supplying several hydrocarbons that are typically obtained from petroleum.

Waste CO2-derived plastic hits tonne scale. 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. The process could also be a proof of concept using methane as a model feedstock molecule to manufacture reagents suitable for consumer liquid fuels. Carbon dioxide gas may be liquefied or solidified. This requires less energy per ton of CO2 than most other electrochemical conversion pathways. 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. US researchers have genetically modified bacteria to eat carbon dioxide and produce isobutyraldehyde – a precursor to several useful chemicals, including isobutanol, which has great potential as a fuel alternative to petrol.
