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 decarbonisation at the local level.

Philippe Haffner, chairman and CEO of Haffner Energy, says: '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.

For years, Haffner Energy struggled to finance small- and medium-scale projects due to insufficient competitiveness against alternative solutions—particularly fossil fuels—and the near-total absence of public support to bridge that gap. Today, this reality is shifting.

The long-awaited take-off of the hydrogen sector, anticipated since 2022, has yet to materialise. However, the breakthrough we are unveiling today will help accelerate its emergence.

The impact is even more pronounced for syngas: thermolysis is poised to become the new standard, replacing conventional biomass boilers, which will gradually disappear—much as steam locomotives rapidly ceded to diesel engines 70 years ago. The global market for small biomass boilers (under 10 MW) is currently valued at around €11 billion annually and is projected to approach €30 billion by 2034, according to Reports and Data.

These two advances are expected to translate rapidly into strong order intake and a substantial increase in revenue. The H6 generation fully aligns with clear market expectations: local, competitive, and sustainable energy production for small- and medium-scale ecosystems.'
