N2 gas is an effective fertilizer for bioethanol production by Zymomonas mobilis
Wow,um,so old data was wrong and new redone data says this bacteria can be fed pure nitrogen gas as fertilizer for cellulosic ethanol production, and it's awesome. Which basically means an oxygen gas separation plant's effuse of nitrogen and CO2 could be fed directly into the bacterium beds. Air Liquide must love this news...

Homologation and functionalization of carbon monoxide by a recyclable uranium complex
Apparently depleted uranium can be used to create a closed loop catalyst for upgrading CO into feedstock for various petrochemical/hydrocarbon processes.

Interesting use of recyclable hydroxides to reform biomass or coal/methane into hydrogen in one step at low temperatures with high hydrogen purity and no CO or CO2 production. Though if you want the CO or CO2, you can heat the resulting carbonate output (recaustication like at paper mills) to recover a relatively pure gas stream and recover the hydroxide for recycling back into the process inputs.

ClearFuels - Technology
Interesting steam reformer that takes clean biomass and converts directly to syngas for feeding a FT process, utilizing FT tail gas for indirect heating of the biomass. Claim low costs, might be could for an algae biomass feedstock.

Solar Thermal Electrochemical Photo (STEP) Carbon Capture could Reduce Atmospheric CO2 to Pre-industrial Levels in Ten Years
Using an externally electrically driven molten lithium carbonate cell to crack CO2 down to C or CO, CO being fed into synthetic fuel processes, C for solid state long term sequestration/storage or as nanotube feedstock. Uses Solar CPV with thermal recovery to heat the cells and drive them electrically. Absolutely no mention of how the CO2 would be captured for input into the electrolysis cell (basically the same as a MSFC fuelcell, only without the hydrogen fuel) though.

Economics Improve for First Commercial Cellulosic Ethanol Plants - NYTimes.com
Supposedly a big drop in the enzyme costs to process non-food biological feedstock such as switchgrass or food production waste such as corn cobs. While biofuels are interesting, I wonder about the feedstock sources. Food production waste has some fundamental limits in quantity, and while switchgrass and other non-food feedstocks can be grown in undesirable land, it must still be cultivated/harvested, which means more land/water use normally...
