Uses of Biogas and Biomethane

BioCH4 is the only established renewable energy fuel source currently directly applicable in all sectors (i.e., electricity, heat and transport fuel). It is easily processed and suitable for versatile power generation in cogeneration plants. Biogas, from which bioCH4 is most widely produced, and thus bioCH4 is a valuable supplier to the energy and transport fuel markets and can be easily incorporated into renewable energy systems. The natural gas grid storage capacity can be used and heat demand can be met regardless of the location and time of biogas output. Using bioCH4 in cogeneration plants and as fuel in gas-powered vehicles contributes to an especially high potential contribution to rising greenhouse gas emissions. This chapter gives an overview of the potential uses for biogas and bioCH4 as a renewable low-CO2 fuel.
