The US Treasury is expected to publish guidance for 45V this summer
Clarification needed for US green hydrogen investment wave
The Treasury is mulling requirements for additionality, temporal matching and deliverability
There is much excitement around the generous US tax credits for clean hydrogen production, but companies are waiting for clarity around their implementation from the US Treasury before finalising investments. The Inflation Reduction Act (IRA) introduced section 45V production tax credits of up to $3/kg for hydrogen produced at sites that emit less than 0.45kg of CO₂e for every kg of hydrogen. The level of credits falls steeply for facilities with higher levels of emissions—just $1/kg is available for producers that emit in a range of 0.45–1.5kg of CO₂e, dropping to $0.75/kg for emissions of 1.5–2.5kg of CO₂e and $0.60/kg for emissions of 2.5–4kg of CO₂e. As an alternative, producers could
