The use of a proven large-scale fuel cell within the CHiP version of iQuadgen® offers a low carbon technology alternative to high efficiency reciprocating bio-engines. Using a fuel cell offers a choice of low carbon renewable fuels, such as biogas (from the anaerobic digestion process) and syngas or producer gas (from the gasification process), as well as a highly efficient use of natural pipeline gas.
The fuel cell produces similar efficiencies to the reciprocating bio-engines with the added benefit of a non-combusting fuel reforming process that produces no NOx (nitrous oxide) or SOx (sulphur dioxide) emissions, commonly referred to as “smog”. The fuel cell breaks down bio-gas, syngas or methane to produce electricity. As the process is non-combusting, emissions associated with any combustion or burning technologies are obviated, producing only water (H2O) and carbon dioxide (CO2) as by-products. The CO2 can be collected from the exhaust and sequestered relatively easily, where Carbon Capture and Storage (CCS) facilities exist.
The fuel cell has a very low visual profile and, if using pipeline delivered gas, does not require the use of road transportation for its fuel source.
