An overview of the Department of Energy's CarbonSAFE Initiative: Moving CCUS toward commercialization

Abstract

The U.S. Department of Energy (DOE) Office of Fossil Energy (FE) National Energy Technology Laboratory (NETL) Carbon Storage Program helps develop technologies that safely and permanently store carbon dioxide (CO2) without adversely impacting natural resources or hindering economic growth. Since 1997, the program has significantly advanced carbon capture, utilization, and storage (CCUS) science and technology, with more than 10.5 million metric tons (MMT) of CO2 safely stored. However, key gaps in experience and knowledge This article is protected by copyright. All rights reserved. This is the author manuscript accepted for publication and has undergone full peer review but has not been through the copyediting, typesetting, pagination and proofreading process, which may lead to differences between this version and the Version of Record. Please cite this article as doi: 10.1002/aic.16855 remain (e.g., the technology, expertise, and processes needed to safely characterize and monitor 50+ MMT-scale geologic CO2 storage sites). DOE's Carbon Storage Assurance Facility Enterprise (CarbonSAFE) Initiative (launched in FY16) is beginning to address this gap. The CarbonSAFE Initiative currently consists of 13 projects in Phase I: Integrated Carbon Capture and Storage (CCS) Pre-Feasibility and 6 projects in Phase II: Storage Complex Feasibility. This paper includes the latest updates from the CarbonSAFE Initiative.

Multiscale CO2 Electrocatalysis to C2+ Products: Reaction Mechanisms, Catalyst Design, and Device Fabrication

“…Unfortunately, they are linked to the formation of increasing levels of CO 2 in the atmosphere. − Carbon capture and storage have provided effective strategies for diminishing CO 2 levels in the atmosphere . Recently, utilization of CO 2 in chemical cycles has initiated promising approaches for the use of carbon neutralization as a way to provide valuable carbonaceous chemical sources …”

“…4 Recently, utilization of CO 2 in chemical cycles has initiated promising approaches for the use of carbon neutralization as a way to provide valuable carbonaceous chemical sources. 5 Utilization of CO 2 in electrochemical conversions provides promising routes for high-efficiency, industrial fuel-generating applications. 6 Successful utilization demands high faradaic efficiencies to give desirable products, stable operation under high current densities, and stabilization for long-term production.…”

Gas and slurry flow behaviors in a CO2‐mineralization spray tower reactor

“…To deal with the increasing greenhouse effects, it is of great significance to develop green and efficient carbon capture, utilization, and storage (CCUS) technology. [1][2][3] As a typical carbon dioxide (CO 2 ) utilization path, the reaction process of using industrial solid waste (carbide slag, desulfurization slag, steel slag, etc.) to absorb CO 2 from flue gas (also known as CO 2 -mineralization technology) can not only effectively captures and stores CO 2 , but also realize the recycling of valuable components such as calcium and magnesium from industrial solid waste.…”

Highly efficient capture of CO2 through the synergy of intramolecular amines within piperazine‐derived alcoholamines

“…Carbon capture, utilization, and storage (CCUS) technology is considered to provide an efficient route to achieve carbon neutrality. 7 Among various CCUS technologies, aminescrubbing-based chemical absorption has always been the most practical technology as it offers advantages over other CCUS processes, such as distillation, 8 membrane separation, 9 and adsorption 10 in terms of rapid separation rate, high capture capacity, and long-term reusability, [11][12][13][14] making it more economical and efficient. The absorbent is the key to chemical absorption.…”
