Linus Engstam

PhD candidate at the Department of Energy and Technology with an interest in power-to-X and sector coupling within the energy system. I have a background in energy and environmental engineering and aspire to be involved in the development of a more sustainable energy system.

My research considers the potential role of hydrogen in the biogas system. For example, methanizing residual carbon dioxide using electrolytic hydrogen can increase methane output while recycling otherwise wasted carbon dioxide, while converting biogas into hydrogen and storing biogenic CO2 can generate carbon-negative hydrogen. In a previous project I developed a model for determining hourly grid emission factors with the purpose of more accurately quantifying the climate impact of dynamically operated electricity demand.

I am also involved in a national competence center for biogas research, Biogas Solutions Research Center, as well as the ERA-Net project  Power-2-Transport where we have developed a software platform for optimising power-to-gas systems in an urban transport context.

At the present I am involved in the courses Energy Market Analysis (TN0351), Energy Systems Planning (TN0347), Energy and Life Cycle Assessment (TN0285) and Bioenergy - Technology and Systems (TN0352), and supervise both bachelor’s and master’s theses.
