Use of Biogas Fuel in Powering Industrial Plants

Even if 10 times much as back then, 10 times a very small percentage is still a pretty small percentage, and thus not very prevalent.

A well-run major sewage treatment works is a net exporter of electricity.

Not enough use of waste biogas. Sewage treatment plants and logoons for remote towns and villages need to start harnessing CH4. Developing countries are realizing the potential for methane and some already have for many years. It is old technology that we should have developed years ago. Our over-reliance on fossil fuels is shameful. Let's look more than a few years ahead.

Without doubt, it has increased.

..."Global direct consumption of biogas was around 35 Mtoe(Million Tonnes of Oil Equivalent) in 2018.(in 2010 it was about 12 Mtoe) Currently, over 60% of biogas production capacity lies in Europe and North America. As the leading biogas-producing region, Europe has around 20 000 biogas plants, with the majority situated in Germany. Most are built for on-site electricity generation and co‑generation, with around 500 plants dedicated to the upgrading of biogas (OIES, 2019).

In the STEPS, projected production of biogas for direct consumption more than doubles, reaching around 75 Mtoe in 2040. Most of this growth comes from centralised plants that are fed by agricultural and municipal solid waste sources in order to meet local power and heating demand. The share of biogas used for power and heat rises from around 70% today to 85% by 2040."...
