§48 / 48ESolar, storage, geothermal, fuel cells

Investment Tax Credit

The workhorse of the market. A percentage of qualified project cost rather than a percentage of output, which makes it the deepest and most liquid credit in the transfer market. Most developers choose between the ITC and the PTC on a single project, and the choice is permanent.

§45XDomestic cells, modules, components, minerals

Advanced Manufacturing Production

The only major credit that requires no project. It is earned on units produced and sold to an unrelated buyer, which is why it moves fastest of anything we broker — and why the transactions are simpler than other credit types.

§45 / 45YWind, geothermal, biomass, hydro

Production Tax Credit

Paid on electricity actually generated and sold, over a ten-year period, rather than on capital spent. That makes it a stream rather than a lump sum — and makes metered output, not just paperwork, the thing a buyer diligences.

  • Ten-year accrual schedule showing the credit remaining in each vintage year
  • Prevailing wage and apprenticeship documentation across the construction period
  • Confirmation that storage co-located at the facility is not separately claimed
  • Current-year inflation adjustment pulled from the IRS annual notice, not a prior-year figure

§45QIndustrial capture, DAC, geologic storage, EOR

Carbon Oxide Sequestration

Paid per metric ton of carbon oxide captured and permanently stored or put to beneficial use. The largest deal sizes in the market, the longest exposure period, and the diligence file that most rewards a buyer who reads the measurement plan before the term sheet.

  • Beneficial use where statutory tonnage thresholds are met

The diligence file

  • Capture verification plan with mass-balance methodology and third-party measurement
  • Sequestration site characterization, well permits, and pore space rights
  • Injection and storage operator agreements, and the long-term monitoring plan
  • MRV reporting that ties tons claimed to tons physically verified
  • Prevailing wage and apprenticeship records — the difference between $29.28 and $85 per ton
  • Confirmation the facility met the construction-start test and the placed-in-service date

§45VElectrolytic and biomass-derived hydrogen

Clean Hydrogen Production

The only credit whose rate is set by a lifecycle emissions model. The same kilowatt hour of electrolysis can earn three dollars per kilogram or nothing at all, depending on how the carbon intensity is calculated and documented. That is where deals are won and lost.

§45ZDiesel-equivalent, SAF, methanol, SRFS

Clean Fuel Production

The successor to the blender incentives for most producers, and the credit that scales with how much carbon a fuel actually avoids across its lifecycle. It also has the shortest runway of any credit we broker, which is exactly why sellers are moving now.

How a credit actually changes hands

Transferability replaced an entire intermediary industry. It is also a filing mechanic with a hard sequence, and getting it wrong is not a pricing problem — it is a credit that does not exist.

Buyer screening
Foreign-entity tests now apply
  • A transfer without a valid registration number is invalid — the buyer does not get the credit and the seller does not get a clean exit.
  • Recapture follows the transferee by statute. The economics are reallocated by contract, which is why indemnity, escrow, and insurance terms carry the weight of the deal.
  • Payment must be cash. The amount paid is not deductible by the buyer and is not income to the seller, which is the mechanic that makes a discount to face value possible.
  • A prohibited foreign entity cannot be a transferee for credits subject to the foreign-entity rules. Buyer-side screening is now part of every closing checklist.
