Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

An integral part of the fuel cycle of future fusion facilities is the isotope separation system (ISS). The Tritium Laboratory Karlsruhe (TLK) is currently developing a system to monitor the concentration of all six hydrogen isotopologues Q2 (H2, HD, D2, HT, DT, T2) in the liquid phase in the cryogenic distillation process of the ISS.
Liquid inactive Q2 were already successfully analyzed under cryogenic conditions via infrared (IR) absorption spectroscopy and calibration data for D2 is provided by previous experiments at TLK. The new experiment T2ApIR (Tritium Absorption Infrared Spectroscopy Experiment) is designed to be fully tritium compatible to perform a complete calibration of the IR absorption measurement system with all six hydrogen isotopologues in the liquid phase under conditions similar to the ISS. This provides a unique non-invasive, inline and real-time measurement system for isotopologic concentration determination, ready for implementation in the cryogenic distillation column.
