The Hydrogen Credit Catalyst
Summary
This policy brief by RMI discusses the potential of a new US tax credit for low-emission hydrogen production, established via the Inflation Reduction Act, to catalyze the clean hydrogen economy and industrial decarbonization. The document argues that the US Treasury's implementation of the credit—specifically regarding standards for grid-connected electrolyzers—will determine whether the incentive drives genuine emissions reductions or inadvertently increases greenhouse gas emissions.
Key insights
- The hydrogen production tax credit (PTC) provides a significant financial incentive of up to $3 per kilogram of clean hydrogen produced over a ten-year period, with eligibility for projects developed as late as January 1, 2033. The credit's 'direct pay' feature is expected to reduce barriers for producers by removing the need for 'tax equity'.
- To qualify for the tax credit, producers of 'green' hydrogen using electrolyzers must demonstrate that they consume between 90% and 97.5% zero-carbon power. While this is straightforward for 'behind-the-meter' systems that bypass the grid, it is more complex for grid-connected systems.
- RMI proposes three essential principles for grid-connected projects to ensure they effectively reduce greenhouse gas emissions: additionality, granular and emissions-accurate accounting, and deliverability.
- Additionality requires that hydrogen producers ensure their new demand for electricity is met with new low-carbon generation. Without this, electrolyzers might consume existing clean power intended for other sectors, while carbon-intensive power fills the gap.
- Temporal accounting must be granular to avoid underestimating emissions; RMI notes a UC Davis paper finding that annual tracking can underestimate the real emissions impact of grid-connected electrolyzers by up to 35%.
- Deliverability ensures that clean power is not only generated but can actually reach the hydrogen project without congestion, preventing the electrolyzer from relying on carbon-intensive power despite having matched clean generation elsewhere.
- The implementation of these standards could have broad systemic effects, including driving investment in geothermal and long-duration storage, influencing international standards for clean commodities like steel and fertilizer, and supporting the development of more accurate global emissions accounting systems.
