A recent study reports anomalous deuterium production in titanium hydride powders subjected to thermal cycling, with isotopic ratios up to approximately 280 times natural abundance. If confirmed, this observation would require an explanation beyond conventional isotopic fractionation mechanisms, potentially pointing to nuclear-scale processes.

However, the analysis shows that the energy budget required for such an effect — exceeding 2×10⁸ J per gram of sample — is incompatible with the observed absence of measurable heat and radiation. The lack of neutron flux and gamma signatures at the expected intensity levels further undermines the plausibility of a nuclear interpretation. Alternative explanations are discussed, including mass spectrometry artifacts, isotopic fractionation, and residual gas contamination.
