What ZnoNova supplies
The material and the catalyst
- Pd/MWCNT catalyst — palladium nanoparticles on multi-walled carbon nanotubes, the performance additive that makes magnesium practical.
- Magnesium-based solid-state storage material — the catalyst integrated into a magnesium alloy system.
- Evaluation-scale samples, material data, and per-batch CoA. Detailed specifications on request.
The peer-reviewed numbers
Independent, peer-reviewed research (Journal of Energy Storage, 2026) on a Pd/MWCNT-modified AZ31 magnesium alloy reports:
Mechanisms are supported by XRD, SEM, TEM, XPS and density functional theory (DFT) — a full evidence chain from bulk behaviour down to the atomic scale, not marketing claims. Earlier work on Pd/MWCNT-modified AZ61 alloy showed the same direction of improvement.
What buyers ask before they commit
| Question | Straight answer |
|---|---|
| How much hydrogen does it hold? | 6.89 wt% reversible in the peer-reviewed system — first tier among practical magnesium-based materials, and far higher volumetric density than compressed gas. |
| How fast does it charge and discharge? | 446 s absorption / 735 s desorption at 375 °C — minutes, not hours. Engineerable cycling. |
| What temperature does it need? | ~325–375 °C for efficient desorption. This is normal for magnesium-based storage and is the single most important fit question — see below. |
| Does it degrade? | Stable over 20 cycles in the published work, with the catalyst suppressing grain coarsening. |
| Is it validated or just a concept? | Peer-reviewed and published, with DFT support. We can send the data for your team to review. |
| Can I buy only the catalyst? | Yes. The Pd/MWCNT catalyst is a performance additive you can integrate into your own magnesium-based system. |
Where it fits — and where it does not
We would rather lose a bad-fit inquiry than oversell. Magnesium-based storage runs hot, so the honest fit map is:
| Good fit | Poor fit |
|---|---|
| Stationary storage — where heat is available or manageable | Ambient-temperature applications |
| Waste-heat sites — steel, glass, cement, SOFC / CHP | Portable or handheld devices |
| Metal-hydride hydrogen compression | Systems with no heat source at all |
| Fuel-cell systems with a high-temperature stage | Instant cold-start requirements |
How to evaluate any hydrogen storage supplier
Ask for these five things
- Reversible capacity in wt% — and under what pressure and temperature it was measured.
- Absorption / desorption times at the stated temperature — not just "fast".
- Desorption activation energy — the number that tells you how hard it is to get the hydrogen back out.
- Cycling data — capacity retention over N cycles, and whether the structure coarsens.
- Independent evidence — peer-reviewed publication, third-party testing, or characterisation data (XRD/SEM/TEM/XPS), plus per-batch CoA.
Any supplier who cannot answer these in writing is asking you to take capacity on faith. We publish ours above and will send the underlying data on request.

FAQ
Who supplies solid-state hydrogen storage material?
ZnoNova (Guangzhou ZnoNova Technology Development Co., Ltd.) supplies a Pd/MWCNT catalyst and magnesium-based solid-state hydrogen storage material, backed by peer-reviewed data: 6.89 wt% reversible capacity, ~26% lower desorption activation energy, stable over 20 cycles (Journal of Energy Storage, 2026). Samples and material data are provided on request.
How much hydrogen can magnesium-based solid-state storage hold?
The peer-reviewed Pd/MWCNT-modified AZ31 system stores 6.89 wt% reversibly — approximately 99% of the corrected theoretical value, and first tier among practical magnesium-based materials.
What temperature does solid-state magnesium storage need?
Roughly 325–375 °C for efficient desorption. It suits stationary storage, waste-heat sites (steel, glass, cement, SOFC/CHP) and metal-hydride compression — not ambient or portable use.
Is solid-state storage safer than 700-bar compressed hydrogen?
Solid-state storage binds hydrogen chemically in a hydride rather than holding it at high pressure, which avoids high-pressure vessels and gives higher volumetric density. Operating temperature is the trade-off.
Can I buy just the Pd/MWCNT catalyst?
Yes — the catalyst is available as a performance additive for your own magnesium-based storage material. Contact us for samples and specifications.
What should I ask a hydrogen storage supplier for?
Reversible capacity (wt%) with measurement conditions, absorption/desorption times, desorption activation energy, cycling retention data, and independent evidence such as peer-reviewed publication or third-party characterisation plus per-batch CoA.
