Plates
Fourteen plates
Figures referenced by the tracks. Photographic plates are illustrative of host environments and are not photographs of the group’s reactor. No plate is evidence of a measured run.
Plate 1
The interface, in cross-section
Metal, dense barrier oxide, hydrated outer shell, promoter island, water. Thicknesses are literature orders, not measurements of the group’s film.
Plate 2
Three actuators, one film
20 kHz pulsed ultrasound at 20–23 W/L, 1 kHz square-wave field, thermal set-point near 70 °C. Each actuator Established alone; the combination is Filed.
Plate 3
The 25 L skid, as filed
316L, near-atmospheric, continuous feed, jacketed, vented. The civil design choice that keeps this out of 350–700 bar storage conversations.
Plate 4
Impedance as a process instrument
A frequency sweep during reaction; a feature vector; a controller set-point. WP2 decides whether the spectrum is a handle or a decoration.
Plate 5
MPC loop, block form
EIS features → state estimate → model-predictive controller → ultrasound power, field waveform, feed rate, jacket duty. No closed-loop run is on the record.
Plate 6
Mass and energy balance, per kg Al
~0.11 kg H₂, ~2.9 kg hydroxide residue at full conversion, ≈ −418 kJ/mol Al released as heat. A civil plant is a heat plant as much as a gas plant.
Plate 7
Cast house — the first host class
Dross, skim and potline scrap already carry a disposal cost. That cost is the first credit in the LCOH envelope.
Plate 8
Remelt yard — clean extrusion scrap
Preferred first-host class: known alloy, short logistics, a decoat gate that is not yet needed. Coatings and lacquer come later.
Plate 9
Residue as a second product
ATH and boehmite are commercial. Phase purity is a WP1 gate, not a brochure line. Without a residue buyer the hydrogen carries the plant alone.
Plate 10
Gallium inventory
Recirculated, the economics on Track A hold. Consumed, this becomes a gallium process that happens to make hydrogen. Decided by a 100-hour mass balance.
Plate 11
Port — the accidental scrap concentrator
Pad, power, water, reverse-logistics packaging aluminium and a safety case that already exists. A host class, not a customer.
Plate 12
Mine depot — civil diesel displacement
Steady loads, remote logistics, no pipeline. Feedstock backhaul decides whether this field is real.
Plate 13
Controls and replication
Blank cell, Ga-free, ultrasound-off, field-off, second laboratory, D₂O isotope check. A pass that also appears in the blank is an artefact.
Plate 14
Gate calendar to April 2027
Counsel engaged, chain of title issued, WP0–WP2 run, WP4 replicated, then conversion triage. A fail saves conversion and national-phase cost before it is incurred.
