Abstract: The present disclosure relates to methods and systems for converting biomass into biofuels and biochemicals. In particular, the present disclosure relates to methods and systems for converting biomass comprising lignocellulosic material into biofuels and biochemicals, such as those comprising fatty acid esters, that contribute to reduction of greenhouse gas emissions.

Abstract: Systems and methods are provided for using fuel cell staging to reduce or minimize variations in current density when operating molten carbonate fuel cells with elevated CO2 utilization. The fuel cell staging can mitigate the amount of alternative ion transport that occurs when operating molten carbonate fuel cells under conditions for elevated CO2 utilization.

Abstract: Molten carbonate fuel cells (MCFCs) are operated at elevated pressure to provide increased operating voltage and/or enhanced CO2 utilization with a cathode input stream having a low CO2 content. It has been discovered that increasing the operating pressure of a molten carbonate fuel cell when using a low CO2-content cathode input stream can provide unexpectedly large increases in operating voltage while also reducing or minimizing the amount of alternative ion transport and/or enhancing CO2 utilization.
