Laboratory of Energy Conversion and Storage (LabX)

The Laboratory of Energy Conversion and Storage (LabX) is a complete infrastructure for testing a wide variety of energy conversion systems, including hydrogen generation units (low and high temperature electrolyzers, fuel processors, etc.), cogeneration and trigeneration units fueled by natural gas, hydrogen, synthetic gas or any mixtures of the previous (e.g., internal combustion engines, fuel cells, etc.), power-to-power systems, and electrical / thermal energy storage systems, as well as heat pumps, absorption chillers and boilers.

LabX leverages over 15 years of experience in the previous Laboratory of Micro-Cogeneration and focuses on experimenting and characterising the units in terms of energy and environmental performances, allowing also to improve physical components and control logics. Tests are executed according to internal procedures as well as to available standards.
