Our Research Areas

At the Division of Electricity, we study many different aspects of electricity: how renewable energy sources such as wind, waves and marine currents can be converted into useful electricity, electricity distribution and systems for energy storage, diamond electronics, plasma technology and lightning research. In addition to the scientific and experimental resources, the division also has a close collaboration with the industry and with other research groups around the world.

Wave power

Ocean waves provide a renewable energy source with high potential to contribute to the global electricity production with minimal environmental impact. Our research group is one of the largest worldwide and has developed and deployed full-scale wave energy converters since 2002.

Wind power

Wind energy is both free of charge and renewable, it has no polluting discharges and is therefore a good complement to regulated energy sources such as hydropower. At Uppsala University, we focus on vertical axis wind turbines.

Marine currents

Marine currents in rivers, straights and the oceans constitute a renewable energy source with good potential. At Uppsala University, research is primarily focused on the generators of marine current energy converters. The goal is to have a power plants that generate electricity with high efficiency at slow water movement.

Hydropower

Hydropower is a renewable energy source and represents a large part of the Swedish electricity production. However, the majority of the hydropower generators in Sweden are 30-60 years old and not designed for deregulated electricity markets with a large penetration of renewable energy sources. The research at Uppsala University is focused on understanding and improving the these generators.

Diamond electronics

Diamond is a semiconductor with extreme properties, such as high breakdown field and high saturation velocity. Diamond electronic devices, such as power diodes and high-frequency field effect transistors, could in principle deliver outstanding performance due to diamond’s excellent intrinsic properties.

Plasma

Plasma science deals with applications of gas discharge plasma to processes and devices, ranging from surface plasma treatment to solution of environmental pollution problems. Within theoretical plasma physics we also study plasma science with applications to fusion energy and material science.

Lightning research

Many tens of thousands of lightning strikes occur in Sweden every year. The lightning research group study the mechanisms of lightning and its interaction with people, electrical equipments and the atmosphere, and provide guidelines for effective lightning protection systems.

Electric energy storage

Electric energy storage and control systems are needed to stabilize electric grids with a large proportion of renewable energy sources. Modern flywheels provide a method for storing electric energy in applications where long time storage is not needed, such as buffering energy in electric cars.

Robot automation

Automation of different industrial processes have a big impact on precision, cost effectiveness and competiveness. In particular, the automotive industry has been implementing robots successfully, but the use of robotics is increasing also in other areas, and the potential for further improvements is large. In our research, we focus on using industrial robots within large-scale production of large electrical machines.

Clean water

Water scarcity is an urgent global problem, affecting billions of people. We are investigating the possibility to power a desalination process with renewable energy sources, such as wave power, to produce freshwater.
