Hydrogen innovation laboratory

A research association made up of Leibniz Universität Hannover (LUH), TU Braunschweig, TU Clausthal, Jade Hochschule Wilhelmshaven and PTB has been receiving support from the Federal State of Lower Saxony since July 2020 initially for 15 months to set up an innovation laboratory for hydrogen technology. After a conceptual phase, the most successful innovation laboratories will be selected for a three-year implementation phase.

 

Cluster of Excellence SE²A

The Cluster of Excellence SE²A is an interdisciplinary research center with the purpose of investigating technologies for a sustainable and eco-friendly air transport system. Scientists from aerospace, electrical, energy and chemical engineering are working on the reduction of emissions and noise, as well as recycling and life-cycle concepts for airframes and improvements in air traffic management. Technische Universität Braunschweig, the German Aerospace Center (DLR), Leibniz University Hannover (LUH), the Braunschweig University of Art (HBK) and the National Metrology Institute of Germany (PTB) have joined forces in this extraordinary scientific untertaking.

Tasks

The central task of the department is the metrology-based realization (national standards, traceability to the SI units) of precision measurements for caloric quantities (heat capacity, heat of transition, reaction enthalpy), liquid properties (viscosity, density, surface tension), dynamic concentrations (atoms, molecules, radicals), reaction rates and pressure from 102 to 109 Pa.

The metrology-based research and services are aimed towards the determination of improved reference data for materials (e. g. density of water, properties of pure fluids) and applications for process optimization such as energy conversion (e. g. kinetic parameters of fluid energy carriers). Additionally, the tasks of the department are to develop new and improved standards (e. g. pressure), measurement techniques, calibration methods and materials.

Furthermore, the department provides competent services in precision measurements and conformity assessments for measuring instruments for calorific values, density and pressure according to the Measurements and Verification Act.
