Deuterium (D) fusion is one of the simplest forms of nuclear fusion, where D fuses with tritium or another D.

As life needs water as far as we know, oceans on an advanced world could supply plenty of it in ocean water.

Extraterrestrial civilizations need a great deal of energy as they advance up the Kardashev scale.

NASA 's Habitable Worlds Observatory and European -led Large Interferometer For Exoplanets could possibly measure D/H.

"So far, so far, it appears to be feasible for exoplanets with plenty of atmospheric water vapor in a region of the spectrum around 8 microns wavelength".
