Study of Trends in System Efficiency for a Biomass Integrated Gasification Fuel Cell Gas Turbine System when Carbon Dioxide Content is Enhanced

The performance of a 30-kW gasifier–SOFC–GT system was evaluated using thermodynamic calculations. Nickel/Gadolinia Doped Ceria (Ni/GDC) anodes were utilized for Solid Oxide Fuel Cells (SOFCs). These systems can achieve high electrical efficiencies of above 50%. The goal of the study is to evaluate trends in system efficiency when carbon...

Negative Emission Power Plants: Thermodynamic Modeling and Evaluation of a Biomass-Based Integrated Gasification Solid Oxide Fuel Cell/Gas Turbine System for Power, Heat, and Biochar Co-Production—Part 1

This article is the first of a two-part series presenting the thermodynamic evaluation and techno-economics of developing negative-emission power plants. The aim of this research is to evaluate the potential of biochar co-production in negative-emission power plants based on biomass-fed integrated gasification solid oxide fuel cell systems...
