Valmet will supply a circulating fluidized bed boiler and flue gas cleaning systems for the Louisiana Green Fuels project in Caldwell Parish. The plant is designed to generate over 300 MW gross using forestry residuals and capture CO2 for permanent geologic storage, aiming for carbon-negative power. Strategic Biofuels picked Valmet after lining up partners for each part of the project. The site will consume more than 3.5 million tons of forestry residuals per year, roughly 400 truckloads daily. The project's carbon-negative claim depends on sustainable sourcing, capture performance, and verified sequestration in a permitted reservoir.

This one is worth reading because it ties biomass power to CCS in a real project. 300 MW gross, 3.5 million tons of forestry residuals per year. That is a serious feedstock logistics question. Curious how the carbon accounting works for the residuals.

Feedstock logistics are the hidden risk here. 400 truckloads a day means a permanent truck fleet and local road impact. The CFB boiler choice is mature, but the CCS integration at that scale has not been proven in biomass yet. What is the timeline to FID?

The carbon-negative claim depends on how the biomass is sourced and what baseline you use. If the forestry residuals would have decayed anyway, the accounting can work. But you need additionality and permanence in the sequestration. Also need clarity on how the captured CO2 is verified.

Interesting that they call it carbon-negative power. Most bioenergy with CCS is carbon-neutral or negative depending on the fuel cycle. The 300 MW number is large for biomass. Worth tracking whether they actually get the permit for geologic storage and how the carbon credits are monetized.

Good to see Valmet in this space. Their CFB boilers are proven in biomass, but the flue gas cleaning for post-combustion capture will be interesting. CO2 capture on flue gas from biomass has different impurities than coal. Might need to watch for corrosion and solvent degradation.
