This study compares three farm-scale biogas utilization pathways—combined heat and power (CHP), biogas upgrading, and bio-methanation—using process simulation and life cycle assessment to identify the most suitable option for on-farm application. Bio-methanation showed the highest practical energy efficiency, …

In Europe, green hydrogen and biogas/green gas are considered important renewable energy carriers, besides renewable electricity and heat. Still, incentives proceed slowly, and the feasibility of local green gas is questioned. A supply chain of decentralised green hydrogen production from locally generated …

Power-to-gas technologies are considered to be part of the future energy sys- tem, but their viability and applicability need to be assessed. Therefore, models for the viability of farm-scale bio-power-to-methane supply chains to produce green gas were analysed in terms of levelised cost of energy, energy …
