World Coal,

The US Department of Energy’s (DOE) Office of Fossil Energy (FE) has selected 17 projects to receive approximately US$18.7 million in federal funding for cost-shared research and development. These projects will develop innovative technologies to generate novel, marketable products using carbon dioxide (CO2) or coal as a feedstock, potentially offering significant advantages over traditional products and creating new market opportunities for coal. The projects are supported through the funding opportunity announcement (FOA) DE-FOA-0001849, Novel Methods for Making Products from Carbon Dioxide or Coal.

These projects will advance FE’s efforts to: improve coal as a feedstock to produce value-added by-products; and to develop and test technologies that can use CO2 – from coal-based power systems or other industrial sources – as the primary feedstock to reduce emissions and create valuable products. The coal feedstock projects will use existing pilot plants to produce an upgraded coal fuel and value-added by-products.

The National Energy Technology Laboratory (NETL) will manage the following projects:
