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,…
This annual impact report highlights Clean Energy Group’s key initiatives and achievements in 2024. It also recognizes the invaluable contributions of our partners—including community-based organizations, state agencies, and national laboratories—whose collaboration strengthens our mission.
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…
This document summarizes some of the key project outcomes of the Resilient Power Project through providing information, knowledge-building support, and technical assistance to organizations working in low-income communities and communities of color across the country.
The draft Connecticut Climate Resilient Energy code is a voluntary code intended to cover the installation of climate resilient energy systems and the provision of power to critical services during grid outages. The code covers the installation of climate resilient energy systems including solar, energy storage, and efficient heating and cooling to maintain living conditions…
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…
