Department of Energy and Mechanical Engineering

Energy Conversion and Systems

The research group of energy conversion and systems in the department of mechanical engineering.

Hydrogen combustion
HVAC test house

Our mission is to educate game-changing energy and HVAC engineers and researchers, to support industries and communities in their decarbonization and green energy transition processes, to make world top class research and to actively communicate research findings to general public and focus on active publishing in high quality scientific journals.

Wind turbine

Our research group covers the energy value chain, from production by sustainable energy sources, to energy conversion, storage and end use. We have strong focus on energy markets and economics, and their modeling and optimization in dynamic environments.

Impact

Our research team is an internationally recognized front-runner in education and research on sustainable energy solutions and technologies. Our main driver is to aid society and industry in the transformation for a sustainable and carbon neutral future. Our focus is on high-level research that has also practical relevance. We accomplish this by educating future game-changers and with international and national cooperation in research projects. 

To meet the requirements from energy industry and society on energy specialists, our research group is also coordinating Aalto’s three master’s programs in energy: Aalto Advanced Energy Solutions (AAE), Innovative Sustainable Energy Engineering (ISEE of Nordic5Tech consortium) and Environomical Pathways for Sustainable Energy Systems (SELECT of EIT Innoenergy). In total, the intake to these is 120-160 students per year. We constantly develop new learning methods, such as Virtual Reality tools in remote locations site visits, and we are also developing hands-on learning experiences in our new Renewable Energy Learning laboratory, RELab.
