It would be helpful if the supporting text explained that anaerobic digestion (AD) produces biogas (a mixture of around 60% methane and 40% carbon dioxide) and digestate, and that biogas can be burned directly in a gas boiler to produce heat or burnt in a combined heat and power (CHP) unit to produce heat and electricity.
Alternatively, the biogas can be cleaned to remove the carbon dioxide and other substances, to produce biomethane, which can be injected into the national gas grid to be used in the same way as natural gas or used as a vehicle fuel. This would demonstrate the options available from AD and replace the text in paragraph W9.1 that states methane gas drives a diesel generator.
