Agriculture and Food Sovereignty: Haffner as a Lever of Survival and Independence (French version - FR)

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

The Current Situation: An Agriculture on Its Knees

In France, one farmer commits suicide every two days. This figure is not an abstract statistic — it is the symptom of a broken economic model:

• Average income below €600 per month for half of all farmers
• Insurmountable structural debt (equipment, land, inputs)
• Total dependence on imported nitrogen fertilizers (derived from Russian or American natural gas)
• Dependence on fossil fuel prices for agricultural machinery
• Unfair competition imposed by European trade agreements allowing food products produced without French standards

Agricultural sovereignty cannot be built on impoverished, indebted farmers who are dependent on foreign energy and inputs. Without financial means, there can be no sovereignty.

The Solution: Transforming Agricultural Waste into Total Autonomy

A Haffner module deployed on a farm or cooperative radically transforms the economic equation. Residual biomass — currently a cost — becomes the engine of complete energy and chemical autonomy.

What a Haffner Module Produces from Agricultural Waste

| Input (Agricultural Waste) | Product | Local Use | |:—————————|:——–|:———-| | Cereal straw | Syngas → energy | Grain drying, greenhouse heating | | Pruning residues (vineyards, orchards) | Syngas → electricity | Powering the farm | | Hedgerow wood, hedges | Syngas → hydrogen | Fuel for machinery and vehicles | | Various green waste | Biochar | Soil amendment, carbon credits | | Grape pomace, draff | Syngas → heat | Drying, distillation |

1. Fuel Autonomy: Zero Tax, Zero Dependence

A farmer who produces their own fuel from biomass waste should pay no tax on this self-produced fuel. This is not a subsidy — it is the fair recognition of local, decarbonized, circular production.

The hydrogen produced by a Haffner module directly powers:

• Hydrogen fuel cell tractors and agricultural equipment
• Utility vehicles on the farm
• Backup generators

At less than €2/kg of on-site produced hydrogen, compared to €8-12/kg delivered, the savings are immediate and structural. An energy-autonomous farmer is no longer hostage to oil prices or supply crises.

What the State must guarantee: the right for a farmer to produce and consume their own fuel from residual biomass without taxation, just as they have the right to consume their own food production.

2. Fertilizer Autonomy: Ending Dependence on Imported Nitrogen

This may be the most revolutionary and least known contribution of Haffner technology to agriculture.

The syngas produced by thermolysis contains hydrogen (H₂). This hydrogen, combined with nitrogen from ambient air via the Haber-Bosch process, produces ammonia (NH₃) — the base molecule for all nitrogen fertilizers.

In short: an agricultural cooperative equipped with Haffner modules can produce its own nitrogen fertilizers from its agricultural waste.

Nitrogen fertilizers currently represent 30 to 40% of variable costs for cereal farms. Their price is directly indexed to natural gas (from which they are derived) and geopolitics — the war in Ukraine multiplied their price by 3 to 4 in 2022. A cooperative autonomous in nitrogen is immune to these shocks.

3. Biochar to Regenerate Agricultural Soils

As detailed in the dedicated biochar section, the solid co-product of thermolysis is an exceptional amendment for agricultural soils:

• Improved water retention (+20 to 40%)
• Fixation and slow release of nutrients
• Reduced need for pesticides (adsorption of residues)
• Carbon sequestration in soils for centuries
• Generation of tradable carbon credits at €110-140/tonne

A farmer who spreads their own biochar on their land improves long-term fertility and earns carbon revenues. It is a complete virtuous circle.

4. The Cooperative Model: Pooling to Maximize

A 2 MW Haffner module sized for a single farm may seem oversized. But the cooperative model changes the equation:

Typical Scenario: Cooperative of 20 Farms

• Each farm contributes its biomass residues
• The cooperative operates 2 to 3 Haffner modules on a central site
• Shared production: energy, hydrogen, ammonia, biochar
• Revenues (sold energy, carbon credits, self-produced fertilizers) are redistributed to members according to their biomass contribution

This model already exists in methanization cooperatives — Haffner adds superior thermal efficiency, input versatility, and a negative carbon balance.

5. Additional Revenues: Transforming the Farm into an Energy Producer

Beyond self-consumption, an equipped farmer can become a producer and seller of energy: | Revenue Source | Mechanism | Order of Magnitude | |:—————|:———–|:——————-| | Local hydrogen sales | Nearby H₂ stations | €6-8/kg sold | | Electricity sales | Grid or collective self-consumption | Market price | | Biochar carbon credits | Voluntary markets (CORC) | €110-140/t CO₂ | | Ammonia/fertilizer sales | Neighboring cooperatives | Market price -30% | | Brush clearing services | Local authorities, ONF, insurers | PES contracts |

A farmer combining 3 or 4 of these revenue streams structurally escapes dependence on agricultural commodity prices. Their income is no longer solely indexed to the price of wheat or milk — it becomes diversified, local, and decoupled from global markets.

6. Food Sovereignty Through Energy Autonomy

France cannot guarantee its food sovereignty if its farmers:

• Depend on Russian or American gas for their fertilizers
• Depend on oil for their machinery
• Close their farms due to insufficient income
• Face unfair competition from imports produced without our standards

Haffner Energy gives farmers the means for their autonomy: self-produced energy, self-produced fertilizers, additional revenues, regenerated soils. It is the necessary condition — previously missing — for true French food sovereignty.

What the State must do:

1. Authorize and exempt the production of self-produced agricultural fuel from residual biomass
2. Fast-track ICPE approvals for Haffner modules in agricultural and cooperative zones
3. Agricultural PES: Pay farmers for environmental services rendered (carbon sequestration, fire prevention, depollution)
4. Guarantee access to credit for cooperatives wishing to invest in these modules — as exists for agricultural equipment

Conclusion: The Farmer, Central Actor of the Transition

Agriculture is not the problem of the energy transition — it is the solution. Its waste feeds the modules. Its soils store carbon. Its cooperatives distribute energy. Its farms produce fertilizers.

What was missing was the technology to close this loop. Haffner Energy provides it.
