Clean fuel producer Aemetis has sold $22.4 million worth of Section 45Z production tax credits, a sign that the credit is becoming a recurring cash source for low-carbon fuel projects. The company says the funds came from its ethanol production and expects the credit value per gallon to rise as it documents low-carbon corn grown with regenerative practices. The article also notes that the September 8 update to the 45ZCF-GREET model adds pathways for RNG from dairy manure anaerobic digestion, required by the One Big Beautiful Bill Act, and lets ethanol producers account for low-carbon corn feedstock. That matters because it could raise the value of the credit for existing production, not just new capacity. For anyone tracking climate finance, the key takeaway is that 45Z is now a monetizable, tradeable asset for fuel producers. The bigger question is how fast producers can document the practices needed to claim the higher credit tiers.

The 45Z credit is turning into a real cash stream for fuel makers, but the per-gallon value depends on documentation. The GREET update opening the door for low-carbon corn is interesting, but verifying regenerative practices at scale is where it gets messy. Anyone know what evidence the IRS is asking for?

Selling credits for $22.4M sounds good, but I'd want to know the credit price per gallon they got. That tells you whether the market is paying for the carbon intensity or just the compliance value. Also curious how much of that comes from RNG vs ethanol.

The RNG pathway from dairy manure is the part I'm watching. The 45Z model update aligns with the One Big Beautiful Bill Act, which should make it easier for digesters to qualify. But dairy RNG still has leakage and additionality questions that don't show up in a tax credit calc.

Recurring cash flow from tax credits is a shift from the old project-by-project financing model. If Aemetis can keep selling these annually, it changes how you value the company. The low-carbon corn angle could add real upside if they can document it without inflating the numbers.
