Haffner Energy have announced Hynoca® Flex 500 IG, a line of hydrogen production units capable of producing 12 tpd of green hydrogen and to be delivered under €3/kg without subsidies.
These units also enable the production of cost-competitive renewable electricity to manage fluctuations in hydrogen demand or ensure energy autonomy.
“The expectations for hydrogen are extremely high, but they remain significantly constrained by the chicken-and-egg problem and the high cost of green hydrogen production,” said Philippe Haffner, Co-Founder and CEO of Haffner Energy. “Our solution simultaneously addresses both challenges, in a market worth over €100 billion worldwide.”
Due to existing subsidies, grants, or tax credits available in most developed countries, green hydrogen is becoming cost-competitive, while providing flexibility and bringing a carbon-free solution. Not only does hydrogen and electricity cogeneration provide a unique solution for managing fluctuating hydrogen demand, it can also ensure energy autonomy of the system or even create opportunities in off-grid locations.
A major breakthrough for the hydrogen market
With optimised energy efficiency (80%) and near-independence from power grids, these units are a scalable decentralised alternative to grey hydrogen and fossil fuels. The technology is modular and standardised, which ensures reliable and replicable deployment at scale. Available worldwide, the first units can be reserved from April 2025, with commissioning of the first units early 2027.
Cost-effective, modular green hydrogen
Hynoca Flex 500 IG combines performance and modularity to meet industrial and mobility needs:
- Flexible production, requiring minimal or no grid dependency.
- Optimisation of CAPEX and OPEX, ensuring that hydrogen can be commercialised under €3/kg without subsidies.
- Rapid deployment, free from grid infrastructure constraints.
- Standardised design, ensuring predictable performance and simplified integration.
Hynoca Flex 500 IG also generates competitive syngas, the precursor to hydrogen. Its low cost opens up new economic opportunities beyond hydrogen production.
A strategic complement to electrolysis and power-to-liquid (PTL)
Each unit generates 58 000 tpy of biogenic CO2, a key resource for PTL (e-fuels) production and a critical enabler for hydrogen from electrolysis.
- 58 000 t of renewable CO2 can convert 5230 t of hydrogen into 42 000 t of e-methanol (or 18 000 tonnes of e-SAF), easy to transport and store.
- 5230 tpy of hydrogen is the volume produced by a 60 MW of electrolyser capacity (4000 hours/year load factor).
Proven, standardised technology for industrial scale deployment
These units build on Hynoca technology, already operational at the centre for hydrogen production, testing, and training in Marolles, France. This unit has been producing hydrogen that meets mobility standards.
Scaling up this technology ensures industrial continuity with no technical risks, optimising implementation for large scale projects.
Hynoca process accepts all possible organic renewable feedstocks, including agricultural residues, sludge, manure, municipal sorted waste, and woody by-products, supporting a circular, low-carbon economy with a near-zero carbon footprint. Compatibility with all organic feedstocks means considerably lower costs, while at the same time significantly improving security of supply.
Each Hynoca Flex 500 IG unit consumes approximately 31 000 tpy of dry plant-based biomass.
