Alléo Energy, a pioneer in sustainable energy solutions, announced a cellulose-to-H₂ process yielding more than 100 kg of H₂/t of cellulosic waste. Alléo’s proprietary process converts cellulosic waste into abundant carbon-negative green H₂, 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 H₂ market, valued at $280 B in 2025 and projected to grow at a compound annual growth rate (CAGR) of 9.3% through 2030.

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 H₂ produced: Alléo-produced H₂ will result 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 H₂ 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.”
