He is currently a professor (tenured) of system technology and applications in renewable electricity generation at the Department of Electrical Engineering, LUT. Currently, the main projects are OffGridH2, AAWE, B2RECoM, and StoRIES. He was the director in LUT GreenRenew research platform and a researcher in internationally recognized Neo-Carbon Energy and Soletair projects. In the Soletair project, chemicals were produced directly from the sun and air. He has built up a zero-energy log house project. He has developed a loss measurement technique, which is included into a new international energy efficiency standard. He has applied bi-directional broadband power line communication in a motor cable between a frequency converter and a motor first time in the world. He has 152 publications with h-index of 28 and six patents in total. He is involved in the boards of both Energy Plus Engineering and Neovolt science-based companies and is also their founding member. Currently, he is the representative of LUT University in the EERA JP on Energy Storage consortium. His current research interests include power-to-X systems, water electrolyzers, solar power, energy efficiency, calorimetric measurement systems, and power line communication. At LUT, Antti teaches digital signal processing and solar power. In addition, he gives specialist lectures in other courses.
