What they make, where they produce, the materials that matter — then what is coming, what it would do to the business, and the moves available. Sector: utility energy. Company profile →
Toshiba Energy Systems & Solutions Corporation is Toshiba Corporation's wholly-owned energy arm, carved out of the parent in 2017. Two halves: power generation systems — thermal, nuclear, hydro and renewables, plus a hydrogen-energy business — and transmission & distribution systems, whose catalogue is power transformers, switchgear including gas-insulated switchgear and gas circuit breakers, surge arresters, protection & control (relays), power electronics, system control, and grid-side software (microgrid, VPP, energy storage). A third, unrelated line is heavy ion therapy equipment.
In hydrogen it develops PEM water-electrolysis stacks and has licensed its iridium-saving membrane-electrode-assembly technology to Bekaert (2024).
Verbatim from the dossier's “What they do” section — sources on the company profile.
No production footprint is recorded in its dossier yet — its HQ country is 🇯🇵 Japan, a registration fact, not a production or sales claim. We say so rather than guess.
Of everything in its products, we track the critical inputs — the materials whose supply is concentrated in few countries, policy-exposed, or hard to substitute — because those are the ones a single measure can move. Each carries its role in the product, quoted from the dossier's own exposure note.
Iridium (`rhodium-iridium`) — trace additive, but the sharpest chokepoint here. The anode catalyst of a PEM electrolyser is iridium oxide. Toshiba's own R&D disclosure states the problem in its own words: annual global iridium production is "in the region of 7 to 10 tons, far less than the 200 tons of platinum, and it costs four to five times more" — and its laminated-nanosheet electrode was built specifically to cu…
The dossier also records the materials it investigated and rejected — the list above is narrowed deliberately, not cherry-picked. Its own words:
Scope. The non-critical remainder of the bill of materials — structural steel, polymers, glass and the like — is not tracked here because it is not supply-constrained: this section covers the constrained inputs, which is where policy risk concentrates, not a full bill of materials.
No upcoming policy in our register currently touches rhodium iridium. The pipeline is re-scanned continuously; this line changes the day that changes.
None of these filed an explicit stage — in-force status defaults from an absent stage: field (flagged below), not a claim any filer made. Each still links to the register entry with its primary source; verify stage before treating as a confirmed baseline.
For a material it buys, a restriction tightens supply and raises input cost — a headwind. Scores are footprint-adjusted and buyer-relative (0–100, higher = more exposed).
Its sector (utility energy) has no downstream edges in our supply-chain adjacency graph — no downstream signal in the register.
For each bought material: the ex-controller producers a procurement team can actually reach, from the alternatives map (derived 2026-10-06), viability-gated — each name carries its deployment status (with the verbatim dossier phrase it rests on), a capture check against the measure being escaped, and any contracted-capacity evidence. Deployable-now names sort first; a developer with zero tonnes is shown demoted, never dressed up as a switch you can make today. Tradability is inherited from the listing layer, never guessed.
lib/policy-transmission.ts): an export prohibition in the measure's name/text → supply restriction; a raw/unprocessed-export limit or local-processing mandate → beneficiation (form change, not unavailability); reporting/disclosure/due-diligence language → compliance obligation; tariff/trade-remedy language → import cost; subsidy/fast-track/relaxation language → support; investment-screening/M&A language → investment control. When the text carries no signal we fall back to the action-type default and label the chip inferred; when neither exists the card says so and derives no response — we never assert a class the evidence doesn't support.lib/iptm-material-country-production.ts; mining stage preferred, refining as fallback — the stage and source year are in each figure's hover text). Ex-issuer supply removes the ISSUING country and renormalises the remaining listed shares (so they sum to 100% of what's left) — alternatives to the country making the rule, never a default ex-China list. Where the issuer holds no measurable share, the card says so plainly instead of implying supply loss.lib/alternative-viability.ts): each named alternative carries a deployment status — operating / ramping / restarting / development / unknown — derived from word-boundary signal phrases in its own dossier (“operating since 1896”, “restarting the … mine”, “FID taken”), and the verbatim matched phrase is shown as the basis so the claim is auditable; a dossier with no signal stays unknown, never guessed. Any evidenced production date is quoted verbatim (“first production targeted H2 2029” → “no tonnes before 2029”) — we never synthesize one. A measure whose own text claims extraterritorial / re-export / de-minimis / foreign-direct-product / percentage-of-value scope triggers the origin-switching warning above the list: such a rule follows the material, not the seller, so a foreign-made alternative can still be captured. Same-issuer register actions targeting an alternative's country and material mark it may be captured, with the entries linked. “Capacity partly committed” lines quote the dossier verbatim — we hold no structured free-capacity numbers and never imply a utilisation figure.How MacroLens tracks this for you. The policy register files new measures daily and this page recomputes from it — the same chokepoints are monitored live on the watchlist and in the full register.
