- [AB2 metal hydride vs magnesium-based storage — which side of the trade you belong on](https://znonova.com/materials/ab2-to-magnesium-hydrogen-storage.html): AB2 alloys release hydrogen at around 120 °C but hold only about 2 wt%; magnesium holds 6.89 wt% reversible capacity at 375 °C (AZ31 + 5 wt% Pd/MWCNT) but needs roughly 325–375 °C, with about 285 °C as the practical floor. The page carries an interactive four-question decision tool that returns 'stay on AB2' whenever the installation is mobile, the available heat is below about 285 °C, or a low operating temperature is a hard requirement — we publish the cases where our own material is the wrong choice. It also states plainly that ZnoNova supplies the catalyst additive at 1–5 wt%, not the storage system and not bulk magnesium.
- [Which catalyst route fits your hydrogen storage substrate](https://znonova.com/materials/catalyst-route-selector): three routes, matched to substrate rather than sold as one product. Pd/MWCNT for magnesium alloys where absorption and desorption speed is the constraint — this is the route with two peer-reviewed Q1 papers behind it. Pd/CeO2/C for AB2 alloys, magnesium and cost-controlled solid-state systems, where cerium oxide creates oxygen vacancies that assist hydrogen spillover and lower the diffusion barrier; cerium oxide costs roughly 700-1000 times less than palladium, so this route carries a far lower precious-metal load. Pd/RuO2/C for advanced fuel cells and early water-electrolysis validation. The page states plainly that a precious-metal catalyst is usually NOT worth adding to AB5 rare-earth hydride, because AB5 already has a very low dissociation and diffusion barrier and operates at room temperature, so the barrier this catalyst exists to break is not present on that material. It also states that performance figures for the Pd/CeO2/C route are still being measured and are not quoted until they exist. Cost context: in a solid-state hydrogen vessel the alloy powder is about 45% of total cost and the transition-metal catalyst is 5-8% of that alloy, so the catalyst is roughly 2.9% of the finished vessel - the share that takes the material requirement from 70-90 kg down to 14.5-16 kg per kilogram of hydrogen stored. ZnoNova supplies the catalyst additive at 1-5 wt% only: not the magnesium alloy, not bulk MgH2, and not finished storage vessels.
  Full measured data set now published, including the pure-alloy baseline and error bars: at 375 °C reversible capacity rises from 6.15 ± 0.03 wt% (pure AZ31) to 6.89 ± 0.05 wt% (+12%); at 325 °C from 2.20 to 3.48 wt% (+58%); absorption t90 at 375 °C falls from 662 s to 446 s (33% faster) and desorption from ~1155 s to 735 s (36% faster). One result is unfavourable and is published anyway: at 350 °C the catalysed material absorbs in 876 s against 804 s for the untreated alloy — slower. The 20-cycle figure in the papers is the test protocol used, not a measured durability limit; this was confirmed in writing by the research team.
