Background and activities
My fields of expertiese relate to thermodynamics of energy storage and conversion systems. Within this, both theoretical and experimental studies are included. Characterising electrochmical systems with respect to both heat and work constitutes one of the back bones in my research. Additionally, I also focus on non-equilibrium thermodynamics with an experiemntal approach to determine the coupling between transport of charge, mass, and heat.
ENERSENSE - a centrally supported research area
ENERSENSE is a strategic research area that focus on the nexus of energy efficiency, energy storage and sensor technology/automation. It is centrally supported from rectors office for the period of 2016-2023. The research ares has three defined themes; Energy efficiency, energy storage, and sensor technology/automation, lead by Prof. K. M. Lien, mysel,f and Drof. D. R. Hjelme, respectivley. I am the leader of ENERSENSE as a centrally supported resaerch area.
Energy storage: According to the international Agency (IEA) more than 80% of the energy supply today is chemically bound and non-renewable (coal, oil and gas). When striving for a society founded on renewable energy, wind and solar energy currently appears to be the most important resources. These technologies offer electric energy that is intermittent, momentaneous, and inadequate for most transportation options. Converting this electric energy into chemical energy (e.g. hydrogen, batteries, and super capacitors) allows for energy systems that supplies energy in the right form, at the right time and at the right place.
Energy efficiency: For the world to meet the target of 2 oC, 50% of our resources and effort should be spent on erngy efficincy, according to the IEA. In Europe, this figure is closer to 67%. Within ENERSENSE we focus on energy efficincy in energy stroage systems, buildings and industrial applications.
Sensor technology: Achieving improved energy storage systems and improved energy efficiency require observation and automation. Within ENERSENSE we focus particularly on developing optical sensors tailored for applications that have harsh conditions, complex environments and small dimensions (20 microns and larger).
Again, ENERSENSE focus on developing research project within the nexus of these three themes and is intended to be developed and grow for the next eight years.
Teaching and guidance
As with my research, the teaching fucuses on thermodynamics and energy storage. This goes with undergraduate courses, bachelor projects, master projects and PhD projects. Occasionally I also give lectures for mid- and high school teachers related to energy conversion, management and storage.
