Our research focuses on generation, storage, and end use of solar and wind power. Our objective is to improve the cost efficiency, energy efficiency, and self-sufficiency of renewable electricity systems. We study different battery technologies, hydrogen and power-to-x fuels as electrical energy storage.

Infrastructure

LUT has a hydrogen production laboratory infrastructure including alkaline (2.8 kW, 0.4 Nm3/h) and PEM (4.5 kW, 1.0 Nm3/h) water electrolyzers. In addition, test benches to study alkaline and PEM electrolyzer cell performance are included. The laboratory is equipped with extensive measurement system to be able to verify hydrogen production rate with mass flow measurement, and electrical power and energy with high-end power analyzers. In addition, the laboratory includes a wide variety of programmable power sources:  laboratory DC power sources up to 330 A of DC and potentiostats that are able to produce DC+AC signal and perform impedance spectroscopy. LUT has also a well-equipped laboratory for experimental testing of power electronics including the 250 kW PHIL simulator of water electrolyzers. For real time gas quality analysis, a mass spectrometer is available in addition to binary gas analyzers.
