Simulating CO2 Pipeline Transport1 min read

Geologic Carbon Sequestration Program Hydrogeology Department Research Highlight

Source:  Dan Hawkes

The anticipated introduction of large-scale geologic carbon
sequestration (GCS) as a means of reducing greenhouse gas emissions will
require the ability to transport massive amounts of CO2 safely and
economically. In a recent paper, a team of scientists led by ESD’s
Alberto Mazzoldi (and including ESD-GCS Program Lead Curt Oldenburg)
focuses on the safety issues related to the transportation of CO2. The
team carried out simulations that coupled two computational fluid
dynamics codes to determine, first, the leakage rates from fully
ruptured aboveground CO2 pipelines for a typical pipeline fluid
composition; and, second, the resulting atmospheric dispersion of the
gas near the broken pipe. Among their findings, they note that
concentrations dangerous to human health could potentially extend
hundreds of meters from the ruptured pipeline.

Berkeley Lab Partners with International Collaborators in Geothermal Energy Research1 min read

January 20, 2021

  Scientists from the Energy Geosciences Division have begun working with European partners on three new geothermal research projects through the Department of Energy’s membership in GEOTHERMICA, a transnational consortium that combines the in-country financial resources and research expertise of 15 participating countries to demonstrate and validate novel concepts in geothermal energy use. This marks the…

EESA Senior Scientist Talks Earthquake Building Resilience1 min read

Berkeley Lab senior scientist David McCallen leads a subproject called Earthquake Sim, or EQSIM, for the DOE’s Energy Exascale Computing Project. He is also professor and director of the Center for Civil Engineering Earthquake Research in the Department of Civil and Environmental Engineering at the University of Nevada, Reno. McCallen recently spoke with Scott Gibson of…

EESA Scientist Coauthors New Comprehensive Guide on Removing CO2 from the Atmosphere2 min read

January 18, 2021

Berkeley Lab researchers are working on ways to sequester more carbon in soil, including through agricultural practices. (Credit: Berkeley Lab) Scientists say that any serious plan to address climate change should include carbon dioxide removal (CDR) technologies and policies, which makes the newly launched CDR Primer an especially vital resource, says Berkeley Lab scientist Margaret Torn, one…
