WASHINGTON, D.C. – The U.S. Department of Energy’s (DOE) Office of Fossil Energy (FE) has selected 11 projects to receive approximately $17 million in federal funding for cost-shared research and development projects for carbon utilization. The projects will develop and test technologies that can utilize carbon dioxide (CO2) from power systems or other industrial sources as the primary feedstock. The research goal of DOE’s Carbon Utilization Program is to reduce emissions and transform waste carbon streams into value-added products.

“According to the U.S. Energy Information Administration and the International Energy Agency, fossil fuels will continue to power our world well into the future. Therefore, it is our responsibility to ensure these fuels are utilized as cleanly and efficiently as possible,” said Under Secretary of Energy Mark W. Menezes. “DOE’s Carbon Utilization Program is investing in cutting-edge technologies to allow us to capture carbon oxides, which will reduce emissions, and then recycle them into economically valuable services like enhanced oil recovery or products like plastics and carbon fibers.”

Projects resulting from this FOA will validate the concept, estimate the technology cost, and demonstrate that the carbon lifecycle of the products offers a path toward an environmentally sustainable and economically viable product.

The National Energy Technology Laboratory (NETL) will manage the selected projects, which follow under four areas of interest (AOI):

AOI 1: Synthesis of Value-Added Organic Products

  1. Dehydration Membrane Reactor for Direct Production of Dimethyl Carbonate (DMC) from CO2 and H2The Gas Technology Institute (Des Plaines, IL) seeks to develop a process and catalytic membrane reactor for producing DMC from captured CO2 and hydrogen (H2). The proposed technology offers an alternative to mitigating CO2 emissions in areas where geologic storage may not be a feasible solution or where the production of DMC could be a low-cost alternative.
