This thesis presents an evaluation of the practicality of using heat pumps to heat feedstock within anaerobic digesters for biomethane production. Given the increasing production of biogas and biomethane in both advanced and developing countries, incorporating alternative forms of renewable energy for this purpose not only enhances production capabilities but also contributes to environmental improvement. Thus, utilizing a heat pump to fulfilll the heat demand of the anaerobic digestion process in biomethane production will amplify environmental benefits. In the introductory section of the thesis, an overview of the anaerobic digestion process will be provided, which is the method utilized in this case study for biogas production, along with an exploration of various technologies employed for upgrading biogas into purer biomethane.
