Key Biogas Cleanup Challenges
> High level of contaminants & high concentration variability
> High contaminant removal costs
> Limited experience with cleanup
> Real-time monitoring of contaminant levels
> Time & cost for purity sampling & testing
> Contaminant disposal–cleanup media generally not
recyclable
> Supply vs demand buffering options

R&D Recommendations
> Assess and improve biogas contaminant tolerance of fuel cells
> Generate data on adsorption properties of contaminants on sorbents/catalysts
> Assess performance of existing cleanup systems
> Cost reduction of biogas cleanup systems
> Develop recycling technologies for gas cleanup schemes
to reduce O&M costs
> Improved gas quality monitoring/sensor development
