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.
- Hydrogen production by water electrolysis
- Improvement of energy and cost efficiency of low temperature water electrolysis technologies (alkaline, PEM, AEM) at cell, stack, and plant level.
- Battery technologies
- Battery degradation phenomena and application development
- Solar and wind power
- Optimization of solar and wind power use in different applications
- Energy efficiency
- Energy efficiency in electricity end use application
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.
