This CEG report contains new analysis evaluating the feasibility of hydrogen power plants as long-duration energy storage resources, based on cost competitiveness as well as equity and environmental impacts.
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,…
In these comments, CEG urges DOE to extend the deadline for comments on the proposed scope of the Environmental Impact Statement for the California Hydrogen Hub by another 60 days and lays out the ramifications of hydrogen energy.
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…
In these comments submitted to the U.S. Department of Energy (DOE) Office of Clean Energy Demonstration, CEG urges DOE to extend the deadline for comments on the proposed scope of the Environmental Impact Statement for the Pacific Northwest Hydrogen Hub by another 60 days. This is due to limited information on the scope and locations…
The U.S. Treasury Department released final guidance on the 45V Clean Hydrogen Production Tax Credit in January 2025. While the guidance did contain the vital “three pillars” of incrementality, temporal matching, and deliverability, which are essential for ensuring hydrogen production does not lead to a massive increase in grid emissions, it also contains several concessions…
Could blending hydrogen with natural gas help decarbonize the natural gas supply chain? This 4-page fact sheet outlines the potential dangers of blending hydrogen and natural gas in pipelines. These dangers include hydrogen’s corrosive effects on pipeline materials, its tendency to leak, and its highly explosive nature. Hydrogen blending is also inefficient and costly: a…
Clean hydrogen has received a lot of interest for its potential use as a tool for decarbonization but has also prompted a lot of concerns. Hydrogen production and use can have serious consequences on water supplies, particularly in areas already facing water scarcity. The production of green hydrogen, as well as certain end uses, can…
Clean hydrogen has received a lot of interest for its potential use as a tool for decarbonization but has also prompted a lot of concerns. Hydrogen production and use can have serious consequences on water supplies, particularly in areas already facing water scarcity. The production of blue hydrogen, as well as certain end uses, can…
Comments on Environmental Impact Statement Notice of Intent for the Appalachian Hydrogen Hub
In these comments, CEG urges DOE to extend the deadline for comments on the proposed scope of the Environmental Impact Statement for the Appalachian Hydrogen Hub by another 60 days and lays out the ramifications of hydrogen energy.
