PhD Candidate – Biomethane Production from Syngas - Climate & Techno-Economic Analysis
Department of Energy and Technology Doctoral Subject: Technology Project Description: Biomethane is traditionally produced through anaerobic digestion of biodegradable biomass and plays an important role in reducing dependence on imported fossil fuels and limiting climate change. To increase biomethane production and meet growing demand in the transport and industrial sectors, there is a need to utilize raw materials that are difficult to convert biologically, such as forest residues. A promising method is biomethane production from syngas generated through thermal gasification of lignocellulose-based biomass. Integrating biomethane production from syngas with conventional anaerobic digestion offers several advantages, including increased gas flow that enables more cost-effective liquefaction of biomethane and improved heat management. Additionally, the supply of external green hydrogen, produced through water electrolysis within the framework of carbon capture and utilization (CCU), can further increase methane production and facilitate upgrading of the produced gas. Duties: We are seeking a motivated PhD candidate who wants to work on the design and evaluation of different system scenarios for biomethane production. The research will involve modeling and simulation from feedstock supply and thermal gasification to biomethane production. The system scenarios will include integration of biomethane production from syngas with conventional biogas plants based on anaerobic digestion as well as supply of external hydrogen. The objective is to evaluate energy balance, climate impact, and techno-economic performance. The candidate is expected to read and critically review scientific literature in English and to publish and present research results in scientific journals and at conferences. The PhD candidate will also participate in doctoral training courses and contribute to departmental activities. The hired person will be part of the national interdisciplinary center of excellence, Biogas Solutions Research Center (BSRC). Within BSRC, new and relevant knowledge is created through collaboration between different scientific disciplines and between researchers and actors from industry and the public sector. BSRC encompasses researchers and support from two universities – Linköping University and the Swedish University of Agricultural Sciences (SLU) – as well as approximately 50 private and public organizations representing the entire biogas system value chain. The center is also financed with support from the Swedish Energy Agency. Qualifications: Basic eligibility is held by those who have completed a degree at an advanced level, fulfilled course requirements of at least 240 credits, of which at least 60 credits at an advanced level, or who have otherwise acquired substantially equivalent knowledge within or outside the country (Swedish Higher Education Ordinance, Chapter 7, Section 39).
