DECENTRALIZED HAFFNER ENERGY THERMOLYSIS: ENERGY INDEPENDENCE WITHIN REACH OF EVERY TERRITORY (French version - FR)

Strategic and Economic Note — EJS

1. The Problem: Dependent and Fragilized Rural Territories

Rural municipalities and intermunicipalities face triple pressure: the structural rise in energy costs, increasing decarbonization obligations (CSRD, SNBC, PNIEC targets), and the costly management of green, agricultural and forestry waste that accumulates on their territories without any valuable outlet.

At the same time, the renewable energy technologies usually offered (wind, photovoltaic, large-scale methanization) require massive investments, long permitting delays (18 to 24 months for a standard ICPE), dependence on the electricity grid, and low resilience in the event of power outages or logistical crises.

2. The Solution: A Haffner Energy Module Installed in 3 Weeks, Without Foundations

Haffner Energy’s dry thermolysis technology (C-iC H6 module) transforms local residual biomass — straw, forestry residues, Class B wood, green waste, refuse-derived fuel — into green hydrogen, heat, and biochar, without combustion, without fine particle emissions, and with no significant need for grid electricity.

Key characteristics of the H6 module (public data):

The process is autothermal: it generates the energy needed for its own operation. No dependence on the electricity grid, no vulnerability to power cuts.

3. What This Changes Concretely for a Local Authority

A Local Hydrogen Station, Immediately Available

The H6 module is designed to serve both as a production unit and a hydrogen refueling station. The local authority’s vehicles — buses, garbage trucks, service vehicles, agricultural tractors — can be refueled directly on site, without dependence on an external distribution network.

At the H6 target production cost (under €2/kg of hydrogen), local hydrogen fuel costs approximately €1.40 per 100 km for a fuel cell vehicle, compared to €10 per 100 km for a gasoline combustion engine vehicle. A 1 to 7 ratio on municipal fleet fuel bills.

Green and Agricultural Waste Becomes an Asset

What the local authority currently pays to dispose of — pruning waste, sorting refuse, crop residues — becomes the raw material for the module. The burden turns into revenue. For every tonne of biomass processed, the module produces 200 kg of high-value biochar (soil amendment, CORC carbon credits monetizable on European markets at €275–420/tonne).

A Financing Lever for Public Services

By integrating biochar valorization revenues into the economic calculation, the net cost of hydrogen production becomes negative. This financial surplus can feed local public service budgets, finance free public transport, or contribute to equipment repayment.

4. Food and Agricultural Sovereignty: Cooperatives at the Heart of the System

Agricultural cooperatives are a natural partner for the territorial deployment of Haffner Energy modules.

By valorizing their crop residues (wheat straw, corn stalks, pruning residues) in a module installed on their land, they simultaneously gain access to:

Bamboo crops on marginal or degraded lands constitute a particularly high-performing feedstock, allowing the valorization of currently unproductive land and massive CO₂ sequestration (40-60 t/ha/year according to GCI data).

5. For Elected Officials: A Regulatory Fast-Track Is Necessary

The only current obstacle is not technical or economic: it is regulatory. Current ICPE procedures impose permitting delays of 18 to 24 months, incompatible with the climate and budgetary urgency of the territories.

A Haffner H6 module, installed in three weeks on an existing logistics platform and coupled with critical infrastructure (hospital, logistics base, agricultural cooperative), should be able to benefit from a provisional operating authorization in less than three months.

We call on elected officials’ associations — and in particular the AMRF (Association of Rural Mayors of France) — to urge the government to create a Regulatory Fast-Track for Territorial Energy Sovereignty: the right to immediate experimentation for any modular decentralized installation coupled with critical infrastructure.

6. Conclusion

Haffner Energy decentralized thermolysis is not a promise: it is a technology available today, with modules assembled in factories and delivered in containers. It transforms the burdens of rural territories — waste, residues, marginal lands — into productive assets of energy, fertilizer, and carbon revenues.

A second module (H4/S-iC), currently under development, should further multiply these capacities — the data has not yet been disclosed to the market, but the H6 technology trajectory indicates a convergence toward an overall production cost close to zero.

France’s energy future will be territorial, sovereign and circular — or it will not be.
