A bottle proved the chemistry. Aircraft, boats and military vehicles tested the proposition. AIRCO’s next wager is that making fuel where it is needed can be worth more than shipping it there.
Furno Materials is a California cleantech company rebuilding how cement is made. Instead of the mile-long rotary kilns that make cement one of the dirtiest industries on earth - roughly 8% of global CO2 - Furno builds compact, modular vertical micro-kilns (the 'Furno Brick') that run at more than 80% thermal efficiency, roughly double a conventional plant. The kilns burn gas-based fuels, eliminate NOx and SOx emissions entirely, cut fossil-fuel emissions by at least 70%, and can reach zero emissions on hydrogen - all while producing standards-grade Ordinary Portland Cement at the point of demand.
