Video Introduction

Fuel cells can utilize solid carbonaceous fuels like coal and biomass, without directly contacting them with air, thereby resulting in lower and more concentrated emissions of CO2 with decreased amounts of NOx, SOx, and particulates, allowing CO2 to be easily captured and sequestered. Therefore, the energy and cost penalties to capture the CO2 will be significantly less than for other technologies.

The overall reaction of a DCFC is also shown in equation: C + O2 = CO2

The fuel use can be almost 100%. The electrical efficiency is expected to be above 70% - almost twice those of current generation coal-fired plants leading to 50% reduction in greenhouse gas emissions.
