Energy Efficiency


The availability of fossil-based energy resources is limited and since consumption is expected to increase, reserves are likely to be used up rapidly.  The combustion of fossil fuels releases CO2 gases which contribute to global warming due to the so-called greenhouse effect.  The EU has set itself the aim of saving 20% of energy p.a. by 2020 so as to reduce energy costs, as well as cutting CO2 emissions by 780 million tons p.a. and achieving increased energy independence from third countries.

In order to achieve these ambitious targets, applied research must begin work right away on optimising the efficiency of energy conversion processes and the integration of renewable energy sources and electrical energy storage devices.  Electric drives are especially important as they are the biggest power consumer, accounting for 60% of Germany's total electricity.

The research area "Energy Efficiency" clusters the expertise of several professors at the university from the following areas:

• Electric drives
• Power electronics
• Energy storage devices
• Control engineering

Public debate on CO2 emissions and particulate matter and the legislation arising from it also provides a link between the areas "Automotive" and "Energy Efficiency". Combustion engines are now required which reduce fuel consumption and exhaust emissions.  Research into potential engine design measures mainly uses simulations (multi-body systems and computational fluid dynamics). Engines are increasingly optimised by means of mechatronic systems such as precisely controlled exhaust gas recirculation, modern injection systems and variable valve trains. The development of electronic components for such systems is also of growing importance.
