A California-based company has filed a patent for technology that could turn carbon dioxide into fuel.

According to a press release, Carbon Sciences, developer of a breakthrough technology to recycle carbon dioxide (CO2) emissions into gasoline and other portable fuels, today announced the filing of a patent application for a highly efficient nano-scale CO2 to fuel reactor, which is the most critical part of the company’s CO2-to-Fuel technology.

The company previously announced several important breakthroughs for the commercial viability of its proprietary CO2-to-Fuel technology including: (1) a low energy enzyme based biocatalytic process, and (2) a proprietary enzyme encapsulation technology that increases the life of key enzymes to reduce the cost of fuel production. Carbon Sciences has now successfully incorporated all of these discrete innovations into a self-contained nano-scale CO2-to-Fuel reactor optimized for the efficient transformation of CO2 and H20 molecules into hydrocarbon molecules that are identical to today’s transportation fuels.

Carbon Sciences is calling these nano-scale reactors “Smart Particles™” which are designed to “absorb CO2 molecules and excrete fuel molecules.”
