Abstract
The production, capture, purification, and storage of biogas for the production of green hydrogen (bio_H2), biomethane (bio_CH4), and biogenic carbon dioxide (CO2) are directly related to sustainability and greenhouse gas emission reduction, as they utilize organic waste. Biogas obtained from Anaerobic Digestion (AD) can be purified (Upgrading) to produce bio_H2, bio_CH4, biogenic CO2, an…
