ZETA · board note · September 2026

Make the evidence travel.

ZETA is building the standards, the registry and the exchange. All three rest on evidence that has to come from places which publish almost nothing. This note proposes the layer that supplies it.

The corridor, as ZETA already describes it

Nothing here departs from the alliance’s own account of the market. It follows it to the fourth step and then asks what happens next.

Step four is the whole problem, and it is a measurement problem before it is a market one. A unit cannot be issued, held and retired unless something evidences what it represents. This note is about where that evidence comes from.

The deadline is fixed, and it is hourly

To count as renewable in Europe, hydrogen must be matched to clean power hour by hour. Not annually, not by a certificate bought afterwards. A registry issuing units against Gulf and North African production must be able to answer, for a given hour, whether the renewable power was actually there. CBAM already charges importers an expensive default wherever the real figure cannot be evidenced, so the cost of not knowing is being paid today.

The grid cannot answer it

In Europe the question is trivial: ENTSO‑E publishes generation and flow every fifteen minutes. We put the same question to every jurisdiction in the corridor, by direct request to each source, in September 2026.

Even the Morocco to Spain interconnector, physically operating today, has its flows published by neither ONEE nor REE. There is no ENTSO‑E for MENA, and waiting for one is not a plan.

The sky publishes what the grid does not

A plant built for export answers to no national grid. What it produced in a given hour is a function of the resource above it, and that resource is measured continuously, from orbit, everywhere, by public agencies. We verified each of these returning data at the corridor’s own coordinates:

• Meteosat full disc, cloud over Europe, all of MENA and Africa, every ten minutes, free and keyless.
• Satellite irradiance and 100 m wind, hourly at any coordinate, with an archive back to 1940 for backtesting a site before it is built.
• Night-time radiance and open grid topology, to corroborate that a site is connected and operating.

This is not a second-best proxy. For a dedicated export plant it is closer to the thing itself, it is the same measurement everywhere, and critically it is independent of the producer. That last property is what makes evidence worth anything.

What we found when we assembled the corridor

No open, licensed, coordinate-accurate register of these projects exists. So we built a first pass from company and government announcements: 38 projects across 21 countries, every one geolocated. Then we looked at what we had.

Tonnes reported as kilotonnes, renewable capacity quoted as electrolyser capacity, target years already passed. One project claims roughly three times total world ammonia production. Every figure came from a real developer’s public announcement.

This is the input the registry will be asked to issue against, and it is the argument for issuing against measurement instead of announcement.

Why this matters strategically

The case for building it is not that the map is useful, though it is. It is that the corridor cannot have a market until it has a shared factual base, and whoever supplies that base becomes the reference point the market is priced against. That position is available now and will not be for long.

Why the pairing is the point

Neither body could do this alone. A standards utility without a regional project pipeline is writing rules for a market it cannot see. A regional pipeline without a standards mandate is a list nobody is obliged to accept. Together they are the only pairing that holds both the data and the authority to make it count, and the shared chairmanship makes the arrangement practical rather than theoretical.

The proposal

One public map, published free at a ZETA subdomain, serving all three workstreams rather than sitting beside them:

• The standards. A worked demonstration of the taxonomy in the open. Easier to consult on a map than in a document.
• The registry. The evidence layer for issuance. Every project is a future issuer; the map holds its coordinates, its hourly resource record and its verification status before the first unit is issued.
• The exchange. Where supply is, what stage it has reached, and how much of it is provable. A buyer cannot budget for a market whose depth they cannot see.

Neutral by inclusion, not by omission

The map spans jurisdictions with live territorial disputes and active sanctions regimes. The instinct is to trim the edges. We propose the opposite: ZETA records every project on the same terms and adjudicates no border. Inclusion is not endorsement, and recording a fact is not taking a side. It is also the only stance that keeps the whole corridor willing to issue into the registry.

What already exists

The Dii Desert Energy project database is the natural spine of the corridor record, and a relationship ZETA holds at chairman level. The public evidence layers are free and verified. The rendering was built and measured this week: 150,000 points and 20,000 arcs at 120 frames per second. The validator ZETA already ships should be surfaced against real records rather than duplicated.

What is being asked

• Agreement that the corridor record is an input to the registry in build, owned by the same specification, not a separate product.
• An introduction to Dii on the project database, and permission to discuss terms.
• A named board sponsor to hold it to the registry data model.
• No budget at this stage. The technical work is done and the hosting is free.
