Methane gas emissions: a greenhouse gas crucial to mitigation efforts
Landfill gas recovery from waste or biogas produced from agricultural manure. These can be used directly for energy or/and upgraded to biomethane to produce heat and electricity. Biogas in particular has a big potential to reduce methane emissions in the agriculture sector. One can also use the recovered methane in the production of hydrogen, although we should favor green hydrogen produced from renewable energy sources, such as wind and solar power, because it results in zero emissions. Reducing methane emissions improves both climate change mitigation and better air quality, because of the synergies in the reduction of greenhouse gases and air pollutants. Also, the methane that is recovered can partly replace the use of impod natural gas, and hence improve energy security to some degree. We need to think ‘circular’ because it reduces greenhouse gas emissions, improves air quality and reduces our energy dependency.
