    As mentioned in this thread, biogas and RNG are significantly more complex than other renewable energy sources. Not only is it a capital-intensive project, but it also demands extreme maintenance and upkeep. Furthermore, the infrastructure requirements of a biogas plant are more complicated than, say, solar panels. Digesters, transportation, pipelines, etc., seem more daunting than installing solar panels or wind turbines.

    I view biogas and RNG production as a niche that should be explored more, as it promotes the circular economy. Unlike other renewables that produce just electricity, biogas and RNG production are a waste management solution. Farms with agricultural waste, manure, etc., can set up a biogas plant to not just manage waste but also generate electricity, fuel (RNG), and natural fertilizers (digestate). It helps reduce atmospheric methane emissions from landfills and maintains soil health.

    Since electrification by solar and wind is easier to scale and promote, many countries have not enacted detailed biogas laws. Complex permits, cross-sector collaboration, and lower political visibility are challenges faced by biogas plants. Furthermore, the industry finds it difficult to draw in investment and policy-driven incentives in the absence of strong carbon credit schemes or infrastructure support.
