Web1 apr. 2024 · Considerable effort has been made for the stimulation of biogenic methane generation from coal in situ and ex situ. For in situ studies, such stimulation strategies as microbial stimulation [ 14] and hydraulic fracturing [ 20] have been applied to existing production wells for the increase of methane production rate. Increasing methane emissions are a major contributor to the rising concentration of greenhouse gases in Earth's atmosphere, and are responsible for up to one-third of near-term global heating. During 2024, about 60% (360 million tons) of methane released globally was from human activities, while natural sources contributed about 40% (230 million tons). Reducing methane emissions by capturing and utilizing the gas can produce simultaneous environmental and economic benefits.
