Data Centers and Artificial Intelligence: The Only Virtuous Scenario (French version - FR)

Technical and Strategic Note — Éric Jacob, Engineer (Maths-Sup, DEA)

The Paradox of Non-Decarbonized AI

Artificial intelligence is presented as the engine of progress. It is — provided that its energy infrastructure does not destroy what it claims to build. A data center consumes power continuously, generates anthropogenic heat, and strains an already saturated electricity grid. Lobbyists are now asking the European Union to abandon its climate goals in favor of AI. This is an admission that the current model is incompatible with the survival of the planet.

AI alone = net destruction. AI + Haffner = virtuous model.

A data center powered by Haffner Energy modules exactly reverses this effect:

Rather than decarbonizing their terrestrial infrastructure, some technology players envision relocating their data centers to places where rules do not exist — orbital space, the Moon, international zones. This vision ignores prohibitive physical constraints: a 1.3-second Earth-Moon latency makes any real-time AI usage impossible, launch and maintenance costs are prohibitive, and cosmic radiation degrades electronic components without a protective magnetosphere.

The truth is simpler: a 2 MW Haffner module installed in less than a month on a concrete slab, carbon-negative and profitable without subsidies, costs a tiny fraction of an orbital launch. The refusal of the terrestrial decarbonized solution is not technical — it is political. It is the refusal to constrain an economic model that externalizes its environmental costs onto the entire planet.

CORE100: The Industrial Response to Data Center Demand

Haffner Energy designed its CORE100 program specifically to meet this demand: 100 modular 2 MW C-iC units, combinable in multi-module configurations according to needs (10 MW, 20 MW, 40 MW and beyond).

What the market has confirmed since the launch of CORE100 in February 2026 is revealing: industrial players, and particularly data center operators, are not asking for a single module, but for connected sets of modules, capable of scaling up and guaranteeing absolute service continuity.

Each 2 MW module offers a decisive logistical advantage: it can be transported on ordinary roads without exceptional convoy and installed in less than a month on a simple concrete slab, without foundations or building permits.

Resilience Through Distributed Architecture: The N+1 Model

An AI data center cannot afford any service interruption. Haffner’s response is distributed architecture with built-in redundancy.

The N+1 principle applied to Haffner modules:

Required Power Modules Needed (N) Reserve Module (+1) Total Deployed
10 MW 5 modules 1 module 6 modules
20 MW 10 modules 1 module 11 modules
40 MW 20 modules 1 module 21 modules

If one module goes into maintenance or fails, nominal power remains at 100% thanks to the reserve module. No service interruption.

On annual availability: Haffner modules operate up to 8,000 hours per year, representing an availability rate of 91.3% (8,000h out of 8,760 annual hours). For a data center requiring 99.9% availability, the N+1 model exactly compensates for this planned maintenance window. A single additional module is enough to guarantee total service continuity, regardless of the cause of a unit’s unavailability.

A Technology That Keeps Advancing

Haffner Energy currently holds more than 80 international patents on its thermolysis and gasification processes. The H6 generation, currently being commissioned at the Marolles site, represents a major technological leap in economic competitiveness. New patents will continue to enrich this portfolio as industrial developments progress.

This accumulation of intellectual property constitutes a bulwark against the many companies worldwide attempting to replicate these processes without mastering their technological depth or the 33 years of accumulated experience. Some of these companies are even trying to financially weaken Haffner Energy through aggressive short-selling positions on the stock, even though it remains a nano-cap listed on Euronext Growth.

A patent without the means to defend it is merely a document. This is why the financial protection of these companies is a matter of national sovereignty, not merely a stock market issue.

The Only No-Loser Scenario

Solution CO₂ Anthropogenic Heat Local Jobs Grid Independence
Nuclear only ✅ No CO₂ ❌ Heat dissipated ⚠️ Centralized ❌ Grid dependent
Electrolysis ⚠️ Variable ❌ Net consumer ⚠️ Limited ❌ Grid dependent
Fossil ❌ Massive CO₂ ❌ Double impact ⚠️ Limited ❌ Imports
AI + Haffner ✅ Carbon negative ✅ Offset by biochar ✅ Non-offshorable ✅ Total

There is no other combination that simultaneously satisfies the energy demand of AI, atmospheric decarbonization, and industrial sovereignty.
