DOE selects 16 research projects for more than $19M in funding to advance Solid Oxide Fuel Cell technology 14 July 2015 The Department of Energy’s (DOE) National Energy Technology Laboratory (NETL) has selected 16 solid oxide fuel cell (SOFC) technology research projects for a total of more than$19 million ($19,358,915) in funding. In Fiscal Year (FY) 2015, NETL issued two funding opportunities announcements (FOAs) to support programs that enable the development and deployment of this energy technology. The projects selected under the two FOAs will receive funding through NETL’s Solid Oxide Fuel Cell Program. The FOAs were awarded with two primary objectives: to design, construct, and field-test a SOFC prototype system; and to support innovations that improve the reliability, robustness, and endurance of SOFC cell and stack technology. One project was awarded funding for a 400 kWe SOFC Prototype System Test. FuelCell Energy, Inc. and its subsidiary will design, fabricate, and test a state-of-the-art 400 kilowatt thermally self-sustaining atmospheric-pressure SOFC prototype system. The 400 kilowatt SOFC prototype system represents an important advancement in SOFC technology development and demonstration toward the ultimate goal of deploying SOFCs in highly efficient coal-based central generation systems with carbon capture. Successful achievement of the project goals is expected to enable the commercial deployment of natural gas-fueled Distributed Generation SOFC systems, which is an intermediate step toward viable SOFC technology for large-scale, coal-fueled, central power generation applications. Cost: DOE:$6,000,000/Non DOE: $4,917,887/Total:$10,917,887 (45% cost share)

The other fifteen projects were awarded funding under two topic areas: Innovative Concepts, geared towards undercutting current SOFC technology costs, and SOFC Core Technology, aimed at laboratory- and bench-scale projects that improve SOFC design.

These projects will move SOFC technology closer to commercial deployment, with some of the small-scale demonstration projects illustrating the potential of SOFC technology to transfer to industry applications within the next 5 to 10 years.
