A perspective on the efficacy of green gas production via integration of technologies in novel cascading circular bio-systems

Presently more energy is sourced from the natural gas grid than the electricity grid in the EU and the US. Furthermore hard-to-abate sectors such as heavy-duty transport are not readily served by electricity. Decarbonised energy systems will require renewable fuels (such as biomethane) to reduce the reliance on fossil-based diesel and natural gas. Anaerobic digestion (AD) is a technology which with other bio-based technologies can effect...
