Alleo Demonstrates Cellulose-To-Hydrogen Process

Alleo Energy, a US biomass reforming technology developer, has demonstrated at commercial scale a process that converts cellulosic waste into carbon-negative green hydrogen.

The Bay Minette, Alabama-based company says the process produces more than one hundred kilograms of hydrogen per tonne of cellulosic waste. The renewable energy requirement is less than 63% of the benchmark established by water electrolysis, enabling production costs well below competing initiatives, Alleo added. It plans to sequester 6 kg CO2 for every kg of hydrogen produced.

“Alleo’s carbon-negative green hydrogen is sustainably abundant and doesn't require subsidies to be profitable; it’s a game-changer," stated Simeon Chow, CEO of Alleo Energy.

The company expects to begin selling hydrogen into the transportation market from its first commercial plant in Bay Minette in a few months.

The Bay Minette site has been operational since 2023. Its first reactor reached nameplate production in liquid fuels focused operations in early 2023. A second reactor commissioned in the first quarter of 2025 has demonstrated the scalability, yield, safety and reliability of the company’s technology in multi-day continuous operations.
