Project Description

Dioxide Materials, Inc. will work to combine technology from three companies to develop a process for the conversion of carbon dioxide (CO2) into transportation fuels (e.g., gasoline, Avgas, etc.). Efforts will focus on scaling and integrating the three process components to produce an integrated pilot plant design. Dioxide Materials’ electrochemical process will be used to convert CO2 to carbon monoxide (CO) and oxygen, with renewable electricity as an input. Water electrolysis, such as 3M’s electrochemical process, will be used to create hydrogen (H2). A mixture of CO and H2 (i.e., syngas) will be sent to Primus Green Energy’s Syngas-to-Gasoline Plus (STG+™) process for refinement to transportation fuels. Dioxide Materials and 3M will work to develop manufacturing technology to scale electrolyzers so that they can be constructed at a size appropriate for integration with a power plant. Primus Green Energy will re-optimize the STG+™ process to account for the absence of methane in the feed stream. Other process components, such as pumps, valves, and heat exchangers, will be designed and integrated into the process to account for the lower temperature and pressure of the outputs from Dioxide Materials’ and 3M’s electrolyzers.

Project Benefits

This project is focused on a novel electrochemical CO2 conversion process to produce gasoline, which will reduce greenhouse gas emissions and yield a highly marketable gasoline product via a process that does not compete with food supplies. The synthetic gasoline will require detergents and other additives in order to be used directly in an automobile, but would not need further processing.
