Replaces 45B (SAF credit) and old $1/gal biodiesel credit.
IRA 45Q (CO2 Sequestration Credit)	US Federal (IRS)	CO2 captured from industrial/power/DAC then sequestered or used	$85/tonne (saline storage); $60/tonne (utilization, EOR); DAC: $180/tonne sequestration, $130/tonne utilization	Per tonne CO2 captured and qualified storage. Tax credit direct-pay or transferable	12 year credit period. Construction begin by 2033. PWA requirements for full value (else 1/5).
IRA 48 / 48E (ITC for Clean Energy)	US Federal (IRS)	Solar, wind, BESS, geothermal, biogas, fuel cells, H2 electrolyzers, CCS projects	30% base ITC; +10% domestic content adder; +10% energy community adder; +10-20% low-income bonus	% of qualified project CAPEX as tax credit. 48E is tech-neutral (post-2025)	48 thru 2024; 48E 2025+. PWA required for 30% (else 6%). Transferable under Section 6418.
IRA 40B (Sustainable Aviation Fuel)	US Federal (IRS)	SAF meeting >=50% GHG reduction vs petroleum jet (ASTM D7566 approved pathways)	$1.25/gal base + $0.01/gal per 1% above 50% GHG reduction (max $0.50 bonus) = $1.25 - $1.75/gal	Per gallon SAF blended. CORSIA default or 40BSAF-GREET CI method	Effective 2023-2024 only; superseded by 45Z in 2025. Some producers still filing 2024 claims.
EU RED III	European Union	Biofuels, bioliquids, biomass fuels, RFNBOs (renewable fuels of non-biological origin = eFuels)	Multiplier: RFNBO 1x, advanced biofuel 2x (count toward 14% transport target)	42% RFNBO target for industry H2 by 2030; 5.5% transport target w/ min 1% RFNBO + advanced biofuels	MS transpose by May 2025. Strict ADD/TMP requirements for H2 to count as RFNBO (hourly matching 2030).
EU ETS + CBAM	European Union	CO2 emissions from energy-intensive industries (cement, steel, H2, fertilizer, aluminum)	EU ETS: ~EUR 70-90/tCO2 (2024-2026). CBAM: same price applied to imports from 2026	Allowances (EUA) auctioned/allocated; CBAM = (Embedded emissions - free allocation) x EUA price	CBAM transitional 2023-2025 (reporting only); full levy from 1 Jan 2026. Covers direct emissions + select indirect.
UK ETS & RTFO	United Kingdom	Biofuels (RTFO certificates); industrial emissions (UK ETS)	RTFO: ~GBP 0.08-0.15/litre equivalent; UK ETS: ~GBP 30-50/tCO2	RTFO credits per certified renewable fuel volume; UK ETS price similar to EU ETS structure	UK-specific post-Brexit; UK ETS diverging from EU ETS. SAF Mandate 2025 (10% by 2030).
Inflation Reduction Act - 45U (Nuclear)	US Federal (IRS)	Zero-emission electricity from existing nuclear plants	$15/MWh (adjusts for inflation), phase-down above $25/MWh energy revenue	$15/MWh * gross kWh; applies to existing merchant reactors	Effective 2024-2032. Targets prevent premature plant retirements.
Section 48C (Advanced Energy Project)	US Federal (IRS)	Manufacturing equipment for clean energy/fuels (electrolyzer, CCS, SAF facility retrofits)	30% ITC on qualified re-equipping CAPEX (with PWA)	$10B total allocation (cap); application-based competitive	Rounds 1-2 allocated 2023-2024; Round 3 anticipated 2025. Can stack with 45V/45Z for project economics.
APPLICATION NOTES
1. Credit VALUES listed are approximate for 2026 planning. Always confirm with latest IRS guidance, CARB LCFS quarterly price, RFS RIN market, and EU ETS spot.
2. CI (Carbon Intensity) is expressed in gCO2e/MJ for LCFS/RED III and kgCO2e/kgH2 for 45V. Use GREET 2023 for US pathways; JEC/COM models for EU.
3. Credit STACKING allowed across federal-state-EU programs. Common stacks: 45V + LCFS + RIN; 45Z + LCFS; 48/48E + 45V/45Q. Verify no double-counting rules per program.
4. Prevailing Wage & Apprenticeship (PWA) is required for 5x multiplier on 45V/45Q/45Z and full 30% ITC. Labor cost uplift is usually small vs credit value.
5. Credit TRANSFERABILITY (IRC 6418) allows sale of unused credits for cash, enabling project finance. Monetization discount ~5-15%.
6. DIRECT PAY (IRC 6417) allows tax-exempt entities (co-ops, gov, tribes) to receive cash in lieu of credit. Also private entities for 45Q/45V/45X first 5 years.
7. CARBON INTENSITY CERTIFICATION: Most programs require third-party verification. LCFS: CARB-approved verifier. EU RED III: ISCC EU or Bonsucro or state scheme. 45V: attestation + 3P certification.
8. EXPIRATIONS: Monitor sunsets carefully. 40B expired 2024; 45V ends 2032 construction-start; 45Z ends 2027; 48 phaseout varies.
