Adding hydrogen in-situ & ex situ during biogas production

Adding hydrogen in the digester during the biogas production process presents the potential of conversion of hydrogen to methane as well as simultaneously upgrading the biogas. The possibility of converting hydrogen to methane and simultaneous upgrading of biogas, with the resulting biogas thus comprising much less CO2.
