Haffner Energy Unveils The H6 Generation

Hydrogen and syngas finally become competitive for small-scale applications

Designed for small-scale units up to 10 MW, the new H6 generation of HYNOCA® and SYNOCA® technologies marks a major breakthrough in the renewable gas economy.

With HYNOCA® H6, the cost of producing green hydrogen from a 5 MW unit falls to €2.34/kg, slashing costs from €3.57/kg in the previous generation and offering a major advantage over electrolyzers, which remain around €7.81/kg.

Meanwhile, SYNOCA® H6 achieves a threefold reduction in CAPEX per thermal kilowatt produced, enabling syngas to outperform heat from conventional biomass boilers on cost and to be markedly more economical than biogas from methanation.

These two advances pave the way for a new generation of local, modular, and profitable units, capable of accelerating real-world decarbonization at the local level.

Philippe Haffner, Chairman and Chief Executive Officer of Haffner Energy, emphasizes that this technological step-change and the unique competitiveness it delivers undoubtedly mark the most significant turning point for our company in the past five years.

An Unprecedented Economic Breakthrough

Producing green hydrogen on a small scale is finally becoming economically viable.

While electrolyzers powered by electricity at €79/MWh show a Levelized Cost of Hydrogen (LCOH) exceeding €7.81/kg, the new HYNOCA® H6 generation achieves just €2.34/kg.

A Deeper Revolution For Syngas

On the thermal side, the new SYNOCA® H6 technology completely redefines current industry benchmarks.

CAPEX per thermal kilowatt produced drops from €1,800 to about €500, a more-than-threefold reduction.

Compact, Accessible, And Quick To Deploy

The H6 range is now commercially available, with the first deliveries expected as early as 2026 for thermal capacities ranging from 500 kW to 5 MW.

These units target a strategic segment: regional and local projects that are easier to finance, faster to install, and based on locally available residual biomass.

Simplified Design, Strengthened Technological Core

Under the hood, the H6 generation is built on three major advancements:

• A significant acceleration of thermolysis kinetics.
  
• A radical mechanical simplification that lowers manufacturing and maintenance costs.
  
• The expansion of Haffner Energy’s thermochemical expertise, now reinforced by new patents stemming from these innovations.
  

A Strategic Turning Point For Decarbonization

With the H6 generation, Haffner Energy eliminates the long-standing tradeoff between economic performance and the energy transition, a compromise that historically favored competitiveness over sustainability.

Renewable gas is now immediately cost-competitive with fossil fuels, while delivering high efficiency and an almost zero-carbon footprint.

This breakthrough unlocks a new generation of regional and industrial projects — smaller, faster, and more profitable.
