Can Wood Waste Power the Future of Aviation?

Southern Energy Renewables is spending $1.4B in Louisiana to turn wood waste into green methanol and sustainable aviation fuel

20 Apr 2026

Louisiana has long been synonymous with oil and gas. Now, a corner of St. Charles Parish is being reimagined as the site of something the state has never seen before: a commercial-scale plant that turns forest leftovers into carbon-negative fuel.

Southern Energy Renewables announced in March 2026 a $1.4 billion facility that will convert regional wood-waste biomass into green methanol and sustainable aviation fuel. The economics are straightforward enough. Forestry operations generate enormous volumes of waste that currently hold no commercial value. The St. Charles facility changes that equation, feeding that material into a gasification process that produces syngas, which is then converted into methanol through established synthesis methods. Layered on top is carbon capture and sequestration, pushing the lifecycle carbon intensity of both outputs below zero.

That last part matters. Carbon-negative fuels aren't just a marketing term here. They're a certified designation under current regulatory frameworks, and they're increasingly what aviation and shipping operators need as blending mandates tighten.

In April 2026, Axens, a French process technology company with deep expertise in bio-based chemicals and renewable fuel conversion, signed a memorandum of understanding with Southern Energy Renewables to collaborate on sustainable aviation fuel process design. It's a significant endorsement. Deploying biomass-to-fuel technology at industrial scale is rare in the United States, and having a commercially proven engineering partner helps close the credibility gap.

For the broader chemicals sector, the project signals something bigger than one facility. Waste streams that once sat entirely outside the conventional crude-to-chemicals chain are now viable feedstocks when the right technologies are stacked correctly. With methanol demand accelerating in shipping and chemical production, and aviation under mounting pressure to decarbonise, the timing is deliberate. Commercial operations are targeted for late 2029.
