LGFCS Prototype System Testing (Final Report)

In the project, LGFCS assembled and tested its modular SOFC Power System that incorporates all critical technology improvements identified for its “product-like” demonstration. This product demonstrator is expected to meet customer and LGFCS performance expectations for operation, availability, durability and serviceability. The principal technology improvements are aimed at increasing the fuel cell power output and reducing the stack degradation rate. Improvements were also made for added system robustness and increased reliability. The objective of this program is to test a 250kWe thermally self-sustaining modular solid oxide fuel cell (SOFC) Power System for a minimum of 5,000 hours while advancing this commercial prototype product demonstrator to a Technical Readiness Level (TRL) 7. The SOFC system was tested on a site provided by Stark State College in North Canton, Ohio. System performance and degradation as well as cost estimates were compared to established SOFC Program performance metrics to assess progress. The major achievements were to assemble, and QA qualify 70 fuel cell strips for 12 integrated blocks into a fuel cell vessel and install it into a generator module with the fuel and power electronics modules on the test site. Performance to date included over 1800 hours on load at 250 KWAC to the grid with a DC efficiency of 61% and AC efficiency of 55%. Power degradation was less than 0.4% per 1000 hours and NOx emissions met standards. The LGFCS SOFC Prototype System (GEN0) was demonstrated in an operational environment and therefore achieving Technical Readiness Level 7. The work presented here represents the efforts of all the employees of LG Fuel Cell Systems. Their dedication and hard work made GEN0 possible and successful.

DE-FE0026098 Final Report - Advanced Materials and Manufacturing Processes for SOFC Power Systems Revision 1

The aim of the project is to qualify an integrated material set and processing solution for selected metallic components of an advanced integrated stack block. As the integrated stack block is the “engine” of the solid oxide fuel cell power system, the project will also support significant cost reductions, increased reliability, and improved performance of the LG Fuel Cell Systems Inc. (“LGFCS”) cell and stack technology to be included in the initial commercial product offering. In the proposed work an integrated material set, and processing solution will be developed using powder metals processing which has been proven to be an enabling technology capable of delivering net or near net shape components, as well as for creating compositions, microstructures, and properties that are otherwise unattainable. Several advanced manufacturing processes will be screened to select one or more that are most advantageous for the selected metallic components when produced at commercial volumes. This work will be accomplished through the integration of metallurgists and processing engineers from Carpenter Technology, with the product design and cost engineers from LGFCS. The expected outcome of the proposed work is an optimized material set and processing solution that will reduce the current cost.

Techno-Economic Analysis of an LGFCS MWe-Class SOFC System (Final Report)

The objective of this project is to perform a range of technical, cost and economic analyses of a MW-scale natural gas fired Solid Oxide Fuel Cell (SOFC) distributed power generation system design. The information generated will provide evidence of the tracking of technology and manufacturing readiness supportive of Technology Readiness Level 7 (TRL7) system testing in the 2022 timeframe that meets the Department of Energy’s (DOE) targets for cost (<$6000/kW) and durability (<0.5% power degradation/1000 hours).

Improved Reliability of Solid Oxide Fuel Cell Systems. Final scientific/technical report

This program is furthering the development of SOFC technology to meet the durability requirements required by the market for the service life and costs for such a power generation technology. SOFC technology provides an environmentally friendly and highly efficient power generation. LGFCS is developing a 1MW pressurized SOFC system for distributed power generation. The planned commercial product is expected to have an efficiency of ~60% (net AC) and fueled by natural gas. The lower carbon content of natural gas combined with the efficient power generation results in significant environmental benefits (lower CO2 greenhouse emissions). The SOFC technology provides a means for efficient utilization of the large US reserves of natural gas and enhances national energy independence. The SOFC technology will initially serve the distributed power generation market and gain market acceptance and smaller power system sizes. The technology is well suited to carbon sequestration given the separated air and fuel streams. The Department of Energy (DOE) envisions a centralized power generation technology that could use coal gasification as an integrated gasification fuel cell (IGFC) power plant at the >100MW scale with CO2 capture.
