The Colors of Hydrogen Production: Emissions, Costs, and Concerns

May 20, 2025

Hydrogen is a colorless gas that can be produced through a wide range of methods using a variety of raw materials or “feedstocks,” such as coal, natural gas, and water. Different production processes for hydrogen gas result in distinct byproducts like carbon dioxide, solid carbon, and oxygen. These differing processes are often assigned a color,…

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

March 3, 2025

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…
