Could concentrated solar energy be used to reverse combustion and convert carbon dioxide back into gasoline? That’s what scientists at Sandia National Laboratories, in Albuquerque, NM, aim to find out by building a novel reactor that can chemically “re-energize” carbon dioxide. The device uses a two-stage thermochemical reaction to break down carbon dioxide to produce carbon monoxide, says Nathan Siegel, a senior member of technical staff at Sandia’s Solar Technologies Department. “Carbon dioxide is a combustion product, so what we’re doing is reversing combustion,” he says. The carbon monoxide can then readily be employed to produce a range of different fuels, including hydrogen, methanol, and gasoline, using conventional technologies.
