Matching Biogas Output with Gas Grid Demand

The AD Centre is developing a biological process that will allow biogas to be produced 'on demand' to match gas grid requirements.

Current AD operations tend to produce gas at a constant rate. This limits the locations where upgraded biogas can be injected to the gas grid as the gas network has to have sufficient year round capacity to accept all of the gas produced.

The AD Centre is working with industrial partners to develop a process that will allow organic material and inorganic gases to be continuously processed to produce biological process intermediates. These intermediates can be separated and stored over extended periods of time, and, as dictated by gas grid demand can be rapidly converted to biogas.

Successful development of the process would make injection of biomethane to the gas grid more applicable at locations that may previously have been limited by low summer grid capacity.
