The IEA’s World Energy Outlooks have no doubt that electrification alone cannot meet our climate goals. That’s why natural gas continues to play a major role. But biogas and biomethane have the potential to replace 20% of that gas, says the IEA’s special report “Outlook for biogas and biomethane: Prospects for organic growth”. At present only a fraction of that is being utilised. Here the IEA summarises their comprehensive report. Costs are the issue. They vary widely as every nation’s ability to process these biogases are different. But even today around 30 Mtoe of biomethane – mostly landfill gas – should be able to undercut the domestic price of natural gas. Meanwhile advances in technology, agriculture, transport and waste management will bring costs down. Policy coordination across these otherwise unconnected sectors is needed. The upside is that biogases can use the existing natural gas infrastructure, and are produced from organic residues and wastes so they’re an energy source available to most parts of the world. The full report includes a detailed assessment of feedstock availability and production costs across all regions of the globe.
