The complete document: the chemistry, the machine that governs it, every filing and the white space each one sits in, everything the platform can do within the group's rules, what it costs, what it is worth, and what has not yet been measured.
One platform, at every level: the reaction, the reactor, the control layer, the patents, the applications, the money, and the tests that have not been run. Fourteen plates carry what prose cannot.
| Filed is not granted | No application here has been examined to grant. A search opinion is not a grant. Issuance is never guaranteed, and the field is heavily patented. |
| Modelled is not measured | The 2.01-million-trial computational campaign is complete and is Modelled evidence. Nothing physical has been measured on the group's own feedstock. Physical validation is described as university or laboratory programme work. |
| Attribution | All intellectual property is exclusively vested in the HydroGien / VivoVac group. No individual is named as inventor. All filings referenced are Australian provisional applications owned directly, and the two international applications derived from them. |
| Withdrawn and recorded | Two claims that appeared in earlier materials are withdrawn in this document and shown as withdrawn: hydrogen intake fractions of "25–40% by volume" in diesel engines, which are physically impossible; and the description of the computational campaign as validation. |
| Not in this document | Defence and military applications, which run on their own channel and appear in no commercial material. Medical, implant and pharmaceutical-grade uses, excluded by standing rule. Space qualification, excluded. Sensing and protonic compute-storage, which are the OPALBLACK ledgers and have their own documents. Nine filings held out of every basket on export-control grounds. Any figure presented as a valuation. |
| Pitch position | GALVANOXIDE is position 2 in the group's order — fuel security. Hydrogen is never led with to a generalist audience; the reserve framing in Part IV is the buyer-facing form. |

Aluminium and water make hydrogen, heat and aluminium hydroxide. The chemistry is a century old and belongs to nobody. What has never worked is controlling it — and control is the only thing this platform claims.
Two atoms of aluminium and six molecules of water give two of aluminium hydroxide and three of hydrogen, releasing about 419 kilojoules for every mole of aluminium consumed. Nothing in that sentence is novel, and this document never says it is.
Aluminium does not fizz in a glass of water, and the reason is a film about two to five nanometres thick that forms the instant bare metal meets air. Beneath a hydrated outer layer of boehmite, a dense inner oxide seals the metal from the water. Every attempt to use this reaction for a century has been an attempt to get rid of that film — with caustic soda, with mercury, with gallium–indium eutectic, with ball milling. Each works, and each creates a new problem: a corrosive waste stream, a toxic metal, a supply chain that runs through one country, or an energy bill that eats the output.
The platform's premise is that the film is not the obstacle. It is the throttle. If the oxide is breached continuously and locally — scored along a wire immediately before it enters the water, or disrupted by a catalyst inside a cartridge — then the rate of the reaction follows how much film is open at any moment, and that is a quantity a machine can hold at a setpoint. The film also carries the information: its electrical impedance changes as it re-forms, so the same surface that governs the reaction also reports on it. That is the whole idea, and everything in Parts II and III follows from it.
A reaction that cannot be turned down is a hazard. The control loop reads the oxide's own electrical signature, resolves it into three parameters, and acts on the four things it is allowed to change — before it ever considers stopping.
The reactor measures across the reacting interface — in the preferred wire-feed arrangement the wire itself is one electrode of the measuring pair — and resolves the spectrum into an equivalent circuit. Three parameters come out: solution resistance, double-layer capacitance and charge-transfer resistance. The third is the one that matters: a rising charge-transfer resistance means the film is re-forming faster than the catalyst is breaching it.
The reaction carries a substantial transport delay: what is admitted now shows in the impedance later. A proportional controller in a system with that delay oscillates. The specification therefore prefers a controller that uses a model of the reaction dynamics to choose a sequence of actions over a receding horizon. This is ordinary control engineering; what is unusual is the variable being controlled — not pressure, not temperature, but the state of an oxide film, read electrically, in situ, across the reacting interface.
Depletion has a signature: a characteristic rise in the impedance parameter that is not reversed by admitting more water. In a cartridge, that is the signal to change the cartridge. Feedstock condition has a signature too, which is why a diagnostic stall protocol — a non-consumptive wetting transient used to characterise feedstock before committing to it — is the subject of its own filing. A machine that can tell the difference between "this batch is poor" and "this batch is finished" can keep running through the first and stop cleanly for the second.
Three forms, one control layer: a sealed cartridge for portable and backup duty, a continuous wire-feed reactor for constant load, and a waste hub that takes what arrives.
A fixed facility that takes what arrives — dross from a smelter, swarf from machine shops, shredder residue, end-of-life packaging — sorts and blends it, and runs a bank of reactors against a blended feed. The specification describes the arrangement: weighbridge and sampling station, covered storage bays, processing lines, blending silos, a reactor hall, central separation, product loading and a control building. The hub is where the feedstock economics of Plate 12 are actually won or lost, because it is the only form that can buy the cheapest metal there is.
Hydrogen, heat, aluminium hydroxide and recovered metals. The fourth output is what makes the arithmetic work at pilot scale — and it is also the thing that breaks the business if anyone builds a plan on selling it at volume.
| Figure | Value | Posture and origin |
|---|---|---|
| Hydrogen from this chemistry | A$9–36 per kg, depending on feedstock cost and credits | Modelled — the group's own range across feed cases |
| Hydrogen from gas reforming | A$1.4–3.5 per kg | Established — the incumbent benchmark this must be read against |
| Published comparator | ≈US$9 per kg with by-product credit; 1.45 kg CO₂e per kg H₂ | Established — Kombargi et al., 2025 |
| Grid-to-wheel efficiency, vehicle case | 10–13% | Modelled — which is why vehicles are not the market |
| Break-even aluminium price, stationary constant load | A$900–2,400 per tonne where diesel exceeds A$3/L | Modelled — the envelope in Plate 12 |
Every independent claim that survived search requires it: the machine may only do what it has been authorised to do, and it signs a receipt for what it did — bound to the physical state of the oxide at the moment it acted.
Industrial control systems log. Supply chains attest. Neither, in the art cited, binds a cryptographic attestation to a measured physical state of the material being controlled at the moment of control. That is the combination the independent claims require, and it is the combination that survived search. Its commercial consequence is specific: a governed reactor can prove to a regulator, an insurer or a counterparty what it did and what condition its feedstock was in — which is the precondition for a compensated obligation on a national reserve, and for a cartridge that a machine will refuse to run without.
Two international families, one searched and one not, standing on Australian provisional applications — with the dates that bind, and the one date that has already passed.

Twenty-five of twenty-six claims returned as novel and inventive, all citations background only. It is the one number in this document that the group did not write — and it is a search opinion, not a grant.
| It carries | An outside check on the invention method: a claim set drafted from the group's own inversion process was tested by an examiner who cited nothing against 25 of 26 claims. It also carries a preliminary positive written opinion, which is the input a national examiner starts from. |
| It does not carry | A grant. National examiners search again and may cite art the international authority did not. It says nothing about whether the invention works — that is a measurement question, and the measurement has not been made. It says nothing about freedom to operate, which asks the opposite question: whether practising the invention would infringe someone else's granted claim. |
| The next decision | Whether to amend the claims under Article 19 before the window closes on 23 September 2026. With a result this clean, the default is to make no amendment; that default should be confirmed by counsel rather than assumed. |
Others found the reaction. Nobody commercialised the control of it. This chapter shows the art that exists, the gap that remains, and what would have to be true for the gap to close.
| Element of the claim | Prior art found | The gap that remains | Posture |
|---|---|---|---|
| Aluminium reacts with water to give hydrogen, heat and hydroxide | Settled chemistry, over a century old; Kombargi et al. 2025 as the modern cost and carbon reference | None — and none is claimed | Established (others) |
| Defeating the oxide film to sustain the reaction | Caustic and mercury routes; ball milling; gallium–indium eutectic (Found Energy, 100 kW in 2025) | Each removes the film and with it the throttle; each brings a waste stream, a toxic metal or a supply-chain exposure. Gallium is China-exposed; the group's route is gallium-free | Established (others) |
| Managing rather than removing the film, so that rate follows open film area | Continuous local breaching by scoring is not found combined with in-situ impedance governance | The examiner cited nothing against it | Filed and searched |
| Classifying oxide state by impedance across ≈1 Hz–100 kHz into a finite set of classes | Electrochemical impedance spectroscopy is a routine technique with a large literature | Its use as the controlled variable of a hydrogen reactor, with the feedstock itself as an electrode, is the claimed step | Filed and searched |
| Authorised operating states and a cryptographically signed attestation bound to that state | Industrial attestation and audit logging; zero-knowledge supply-chain proofs (for example US 11,196,562) | None found binding attestation to a measured physical state of the material under control | Filed and searched |
| Authenticated feedstock — a consumable the machine verifies before admitting water | Consumable authentication exists in other fields | Combination with the oxide-state controller is the claimed step; the physical-fingerprint element carries its own freedom-to-operate question against 2006 coating-PUF art | Filed; FTO read outstanding |
| A dual catalyst derived from waste streams | Catalysed aluminium–water art; no anticipating waste-derived dual composition found by the group | Unsearched. In the United States the earlier family can support an obviousness objection; common ownership at the priority date must be shown | Filed, unsearched |
| The economics of the reaction | Eskin 2024: converting primary metal at market prices destroys value. Kombargi 2025 sets the cost floor | No gap — this is the constraint the platform is designed around, not a claim | Established (others) |
Sixty applications in six families, carried from a group map of 412 across the whole substrate. What was removed, and why, is named — because a list that includes everything is a list that decides nothing.

Two prices decide everything: what the aluminium costs and what the diesel it displaces costs. Inside a narrow envelope the platform clears comfortably. Outside it, no amount of engineering saves it — and the document says so.
The largest form the platform can take is not a product at all. It is a national fuel reserve held as metal — and the group's place in it is the release layer and the cartridge standard, not the metal.
| Form | Duty | Feedstock | Status |
|---|---|---|---|
| Cartridge | Portable and backup power; the authenticated consumable that carries the licensing model | Prepared aluminium charge plus catalyst | Filed; none in production |
| WireCharge skid | Deployable off-grid charging and refuelling at depots; 11 kW and 22 kW AC classes, a DC battery-buffered class, and a 350/700-bar module | Aluminium wire on a spool with a pedigree identifier | Provisional drafted 14 Feb 2026; filing to be confirmed; no pilot yet run |
| Wire-feed reactor, fixed | Constant-load stationary power at remote sites where diesel exceeds A$3/L | Wire, or shredded and blended scrap | Filed; not built at production scale |
| Waste hub | Regional processing of dross, swarf and mixed scrap into hydrogen, heat and hydroxide | Whatever arrives, sorted and blended | Described in the specification; none built |
| Strategic reserve tranche | National insurance; released only when the alternative is no fuel | Scrap and dross held by industry under obligation | Legal vehicle exists; concept staged and gated |
| 2026–27 | Measure and designate: first laboratory results, a Ministerial direction under the Strategic Reserve Act, inclusion in the Critical Minerals Strategic Reserve, and an ARENA expression of interest — all lodged by 31 October 2026. |
| 2027 | Demonstrate: a 10-kilotonne pilot stock and a sub-megawatt governed reactor, with a host site. Bell Bay is the natural candidate — 195 kt of capacity, about 355 MW of hydro load, a contract lapsing 31 December 2026 and an A$60 million-a-year gap — and it needs a customer that is not the world metal market. |
| 2028–29 | A 100-kilotonne critical-site tranche held by industry under a minimum-stockholding-style obligation with a Commonwealth put. |
| Beyond | One million tonnes on the insurance-value study. Parity with the 2.7-million-tonne diesel reserve only if a Minister owns the probability assumption — which is a political decision, not a technical one, and the document says so. |
The platform is filed, searched and modelled. It is not measured. Everything below is arranged so that the first measurement arrives before the first claim.
The problem belongs to them. A smelter facing a lapsing power contract, a miner paying A$3–4.25 a litre for remote diesel, a refinery holding 30 days of cover — each owns the cost of the next interruption, and none of them can get an answer about their own feedstock, their own duty cycle and their own site unless they pay for that seat. It is the joint-industry-programme model their sectors already use: several operators share a pre-competitive cost none would carry alone, and each gets the answer first. On either outcome the sponsor buys a decision worth more than it cost — and a negative result is an expensive no, bought cheaply and early.

| Term | Meaning |
|---|---|
| Managed passive oxide | The thin natural oxide film on aluminium, kept and controlled rather than stripped, so that the reaction can be governed rather than merely started. |
| Charge-transfer resistance | One of three parameters resolved from the impedance spectrum. Rising, it means the film is re-forming faster than the catalyst is breaching it — the reactor's primary feedback signal. |
| Impedance classification | Reading the film's electrical response across roughly 1 Hz to 100 kHz and sorting it into a finite set of states. |
| Authorised operating state | A condition the machine is permitted to be in. Transitions between states are what the attestation layer records and signs. |
| Attestation artefact | A cryptographically signed record of what the machine did and the physical state it was in when it did it. |
| Dual-dataset export (DPX-IP) | A faithful projection of a result that can be published without the trade-secret variables — what makes results-vest-in-the-group compatible with a university partnership. |
| Dross | The oxide-rich skim from molten aluminium: a smelter's disposal cost, and the cheapest feedstock on the ladder. |
| Category A | In an international search report, a citation of general background relevance only — no bearing on novelty or inventive step. |
| Article 19 | The single opportunity to amend the claims of an international application after the search report. For this family the window closes 23 September 2026. |
| Corridor | A planning range — floor, target, stretch — for a build-to-sell line. Never a valuation until it passes the pricing gate. |
