In July 2025, Congress acted to accelerate the phase-out of the Investment Tax Credit (ITC), bonus credits and Direct Pay provision. Community-serving solar, wind, and energy storage projects are typically eligible for a 30% baseline credit, available to tax-exempt entites through Direct Pay. This fact sheet provides a timeline for the ITC eligibility of both…
This Direct Pay Fact Sheet details which types of tax-exempt entities are eligible to receive direct pay, outlines the process to receive direct pay, and introduces additional resources.
This fact sheet evaluates the viability of hydrogen as a long duration energy storage (LDES) technology. It examines the costs, efficiency, infrastructure considerations, and potential harms of hydrogen power plants.
This fact sheet covers the inefficiencies of hydrogen liquefaction, on top of the existing inefficiencies of hydrogen production. It details the high costs, high energy consumption, losses due to evaporation, safety concerns, storage and transportation issues, and global warming impacts of hydrogen liquefaction.
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.
CEG submitted comments to the Massachusetts Department of Energy Resources (DOER) in response to DOER’s request for stakeholder feedback regarding the Advancing Massachusetts Power (AMP) straw proposal.
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,…
A battery storage installation at Boston Medical Center demonstrates how hospitals can integrate energy storage into an efficiency or sustainability program to better manage peak demand and lower costly demand charges. The project is profiled in this case study by Clean Energy Group. Boston Medical Center (BMC) is the largest and busiest trauma and emergency…
A Massachusetts pilot program provides a replicable and scalable model for bringing renewable energy, battery storage, and electrification to low-income households. The Cape and Vineyard Electrification Offering (CVEO) is run by the Cape Light Compact, an energy services provider serving 210,000 customers in 21 towns on Cape Cod and Martha’s Vineyard. The CVEO pilot is…
Comments on the Repeal of Greenhouse Gas Emissions Standards for Fossil Fuel-Fired Electric Generating Units
Clean Energy Group (CEG) submitted these comments to U.S. Environmental Protection Agency (EPA) administrator Lee Zeldin in regards to Docket ID No. EPA-HQ-OAR-2025-0124.
