Demeter Energy is developing a commercial biomethanol and carbon capture facility at Seaport Manatee in Florida. The project would turn sustainably sourced biomass into roughly 100,000 metric tons of low-carbon biomethanol per year and capture about 200,000 metric tons of biogenic CO2 for permanent storage. Biomethanol is being positioned as a marine fuel and feedstock for low-carbon chemicals and sustainable aviation fuel. The company says the plant would anchor a wider portfolio of renewable fuel projects in the Southeast, and it is now working through engineering, environmental review, permitting, feedstock procurement, and financing. No final investment decision has been announced yet, and key details like feedstock contracts, hydrogen supply, and cost are still unclear. The project is worth tracking because it combines fuel production with carbon capture at an active port, but the carbon math will depend on the full supply chain.
