However, their operating mechanism and scale-up feasibilities need to be further explored.<\/p>\n<p>Biogas produced by anaerobic digestion is an important renewable energy carrier. Nevertheless, the high CO 2 content in biogas limits its utilization to mainly heat and electricity generation. Upgrading biogas into biomethane broadens its potential as a vehicle fuel or substitute for natural gas. CO 2-to-CH 4 bioconversion represents one cutting-edge solution for biogas upgrading. In situ bioconversion can capture endogenous CO 2 directly from the biogas reactor, is easy to operate, and provides an infrastructure for renewable electricity storage. Despite these advantages, several challenges need to be addressed to move in situ upgrading technologies closer to applications at scale. This opinion article reviews the state of the art of this technology and identifies some obstacles and opportunities of biological in-situ upgrading technologies for future development.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Upgrading biogas into biomethane broadens its applications and increases the value of biogas.
