Perspective on methane capture strategies from natural low-level emissions

Climate change is a pressing issue that confronts human existence in today's world, and its consequences have already started manifesting at a more rapid rate. The biggest culprit of climate change is methane (CH4), a potent greenhouse gas. Consequently, methane emissions must be controlled effectively to prevent global warming. This review is an analysis of the literature available for methane capture, listing different types of adsorbents, highlighting standout materials dealing with the capture of both low and high concentrations of methane, and discussing progressive trends of materials that will help in tailoring adsorbents for better methane adsorption. This article also suggests a mixed membrane matrix as a future perspective by VOS Viewer analysis for the effective capture of methane, along with several techniques that can enhance the technical feasibility, economic viability, and environmental implications. As a result of understanding the challenges and opportunities associated with methane capture, we aim to address the concerns of residents and industry stakeholders regarding methane capture.
