- Editorial: Methane: A Bioresource for Fuel and BiomoleculesPublication . Kalyuzhnaya, Marina G.; Kumaresan, Deepak; Heimann, Kirsten; Caetano, Nídia; Visvanathan, Chettiyappan; Parthiba Karthikeyan, ObulisamyMethane (CH4), a highly reduced C1 compound, is one of the long-lived atmospheric gases with high global warming potential i.e., 28–36 times that of CO2 over 100 years. The atmospheric levels of CH4 reached ∼1863 part per billions (ppb) in 2014, and annual increase of atmospheric CH4 level thereafter measured as ∼10 ppb. The CH4 is projected to drive the rise in global temperature of ∼4–6◦C by 2050, and thus it is currently considered as the main target for global climate stabilization and mitigation (COP-21, 2015). Capturing anthropogenic CH4 to produce value products is highly feasible, but the great challenge is that to tap, concentrate, purify, store, transport, and utilize the CH4 from different point emission sources is presently not economically viable.
