Guidance for Calculating Residual Mix

Residual mixes are the attributes of unallocated or unclaimed energy delivered to customers on the electricity grid and are a critical tool that prevents the double counting of clean energy and supports accurate calculations of greenhouse gas emissions resulting from electricity use. To date, there has been no consensus on what data is needed and …

Residual Mix Applications and Existing Data

This document, released by CRS’s Clean Energy Accounting Project (CEAP), is intended to provide background on how residual mixes (electricity delivered as part of system mix and untracked or unclaimed energy) and associated emissions should be defined and calculated in the U.S. for different uses. Residual mix calculations are often used for greenhouse gas emissions …

Comments to DOE’s Office of Clean Energy’s DE-NOI-0202301 (Clean Hydrogen Hubs)

CRS’s comments pertain to DOE’s potential demand-side support mechanisms for clean hydrogen hubs (H2Hubs). Key recommendations include ensuring support for both compliance and voluntary market demand and designing an eligibility-based selection process that considers the amount of renewable resources used to produce hydrogen the carbon intensity of particular products as well as social impact and …

Comments to the EPA on Clean Air Act (CAA) Section 111 Proposed Rule

CRS proposes that Section 111 of the Environmental Protection Agency’s Clean Air Act require retirement of energy attribute certificates (EACs) to demonstrate use of low-GHG electrolytic hydrogen and that renewable fuel certificates be obtained and retired for low-GHG hydrogen produced by steam methane reforming with biomethane or renewable natural gas to avoid double counting.  Low-GHG …

Scope 3 GHG Accounting for Upstream Clean Electricity Use

In recent years, companies have begun working to reduce electricity-related greenhouse gas (GHG) emissions in their upstream supply chains and support supply chain practices that advance clean energy worldwide. However, companies implementing these actions struggle to reflect the carbon free attributes of supplier clean electricity use in their scope 3 footprints. This Clean Energy Accounting Project …
