Alléo Energy Unveils Carbon-Negative Green Hydrogen System

Alléo cellulosic waste to hydrogen conversion facility

BAY MINETTE, Ala.-- Alléo Energy, a pioneer in sustainable energy solutions, today announced a cellulose-to-hydrogen process yielding over one hundred kilograms of hydrogen per ton of cellulosic waste. Alléo’s proprietary process converts cellulosic waste into abundant carbon-negative green hydrogen, capable of achieving negative Carbon Intensity (CI) scores that surpass competing approaches. By transforming this waste into clean energy, Alléo is poised to contribute a significant step forward for the global hydrogen market, valued at $280 billion in 2025 and projected to grow at a CAGR of 9.3% through 2030.

Alléo’s carbon-negative green hydrogen is sustainably abundant and doesn't require subsidies to be profitable; it’s a game-changer.

The renewable energy requirement of the Alléo process is less than 63% of the benchmark established by water electrolysis. This efficiency enables production costs well below competing initiatives, making Alléo green H2 scalable, safe, and reliable for widespread adoption. Alléo has achieved this production in a commercial-scale reactor under multi-day operations. Alléo intends to sequester 6 kg CO2 for every kg of hydrogen produced, resulting in a six-fold reduction in greenhouse gas emissions.

“In a few short months, we expect to begin selling H2 into the transportation market from our first commercial plant in Bay Minette. Alléo’s carbon-negative green hydrogen is sustainably abundant and doesn't require subsidies to be profitable; it’s a game-changer," said Simeon Chow, CEO of Alléo Energy. “We want to thank our investors and partners who have carried us to this point. We believe their patience will be rewarded as we execute our business plan to scale up production at multiple sites around the world.”

Alléo's Bay Minette facility in Alabama, operational since 2023, has proven its reforming technology on a commercial scale. The first reactor achieved nameplate production in Q1 2023 in liquid fuels focused operations and commissioned a second reactor in Q1 2025 demonstrating scalability, yield, safety, and reliability in multi-day continuous operations.
