Emissions Accounting for the Hydrogen Production Tax Credit: Key Gaps in the 45VH2 GREET Model

The Greenhouse gases, Regulated Emissions, and Energy use in Technologies (GREET) model is used to determine the lifecycle emissions of various energy sources, expressed as carbon equivalent emissions, and creates the framework for many monetary and market incentives related to energy production. In some cases, the values, assumptions, and calculations within each GREET model have the power to allow dubiously credible fuels to be classified as clean energy and benefit from supportive tax credits and fuel standards. Developed by the US Department of Energy’s Argonne National Laboratory and first released in 1995, the GREET model has been updated and developed for specific uses, including a version tailored to the 45V Hydrogen Production Tax Credit labeled 45VH2-GREET.
