The primary motivation for this research has been to investigate the mitigation technology of sequestering the CO2 in deep geological formations, particularly saline aquifers. The displacement of water by CO2    is critically dependent on the physical property known as relative permeability.  By measuring the relative permeability of CO2 gas and water in an experimental apparatus, we were able to determine that the phenomena of CO2 solution and dissolution have very significant effect on the displacement of CO2 gas into water. https://escholarship.org/uc/item/2qt5x4js Fri, 22 Oct 2021 00:00:00 +0000 Horne, Roland N. https://escholarship.org/uc/item/9xg9n2pj This report summarizes work by Winrock International, Lake County Resources Initiative (LCRI), and other Lake County, Oregon partners to implement hazardous fuel reduction/biomass energy pilot activities in WESTCARB Phase II (2006-10). Wildfire is a significant source of GHG emissions in Oregon and throughout the WESTCARB region. WESTCARB developed methodologies to evaluate, validate and demonstrate the potential of reducing hazardous fuel for biomass energy to contribute to GHG mitigation and adaptation. The report describes hazardous fuel reduction pilot activities on Federal and private lands in Lake County; pre- and post-treatment measurements to quantify forest carbon impacted by treatment and/or fire; analysis of data from these pilots to determine the net GHG impact of the fuel reduction treatments; and related work by LCRI to facilitate continued hazardous fuels reduction efforts in Lake County. https://escholarship.org/uc/item/9xg9n2pj Mon, 18 Oct 2021 00:00:00 +0000 Goslee, Katie Pearson, Tim Grimland, Sean Petrova, Silvia Walls, J. Brown, Sandra https://escholarship.org/uc/item/9s01r425 The West Coast Regional Carbon Sequestration Partnership (WESTCARB), in collaboration with Shell Oil Co. performed site characterization for a potential small-scale pilot test of geologic sequestration of carbon dioxide (CO2). The site area, know as Montezuma Hills, is near the town of Rio Vista in northern California. During the process of injection at a CO2 storage site, there is a potential for seismic events due to slippage upon pre-existing discontinuities or due to creation of new fractures. Observations from many injection projects have shown that the energy from these events can be used for monitoring of processes in the reservoir. Typically, the events are of relatively high frequency and very low amplitude. However, there are also well documented (non-CO2-related) cases in which subsurface injection operations have resulted in ground motion felt by near-by communities. Because of the active tectonics in California (in particular the San Andreas Fault system), and the... https://escholarship.org/uc/item/9s01r425 Mon, 18 Oct 2021 00:00:00 +0000 Daley, Thomas Haught, R.

The Panel, composed of experts from industry, trade groups, academia, and environmental organizations, was asked to: 1. Identify, discuss, and frame specific policies addressing the role of CCS technology in meeting the State’s energy needs and greenhouse gas emissions reduction strategies for 2020 and 2050; and 2. Support development of a legal/regulatory framework for permitting proposed CCS projects consistent with the State’s energy and environmental policy objectives. The Panel held five public meetings on April 22, June 2, August 18, October 21, and December 15, 2010,7 to arrive at its findings and recommendations. These meetings were designed to solicit input from technical experts and key stakeholders and... https://escholarship.org/uc/item/9258g443 Mon, 18 Oct 2021 00:00:00 +0000 California Carbon Capture and Storage Review Panel https://escholarship.org/uc/item/8c00350j DRAFT Final contract report prepared by CIEE for the California Energy Commission; contribution to WESTCARB Phase II. The West Coast Regional Carbon Sequestration Partnership (WESTCARB) is one of seven partnerships that have been established by the U.S. Department of Energy (DOE) to evaluate carbon capture and sequestration (CCS) technologies best suited for different regions of the country. The West Coast Region comprises Arizona, California, Hawaii, Nevada, Oregon, Washington, Alaska, and British Columbia. Both terrestrial and geologic sequestration potential has been evaluated in the Region during Phase II of the project. A centralized Geographic Information System (GIS) database of stationary sources and geologic and terrestrial sink data was enhanced, incorporating relevant project data. https://escholarship.org/uc/item/8c00350j Mon, 18 Oct 2021 00:00:00 +0000 Mateer, Niall Beyer, John Henry Burton, Elizabeth Goslee, Katie Hwang, Lorraine Myer, Larry Myhre, Richard Stone, Marian https://escholarship.org/uc/item/7mn6x3x4 WESTCARB (the West Coast Regional Carbon Sequestration Partnership) is one of seven research partnerships co-funded by the U.S. Department of Energy (DOE) to characterize regional carbon sequestration opportunities and to develop action plans for pilot-scale validation tests. WESTCARB is exploring opportunities in a six-state region (California, Oregon, Washington, Nevada, Arizona, and Alaska) for removing carbon dioxide (CO2) from the atmosphere by enhancing natural processes and by capturing it at industrial facilities before it is emitted; both will help slow the atmospheric buildup of this greenhouse gas (GHG) and its associated climatic effects. A key part of the project is identifying subsurface locations to store the captured CO2; such sinks include deep geologic formations such as oil and gas reservoirs, and saline formations that are essentially leak-proof. These potential sinks will then be matched with the major CO2 sources such as the main utilities and industrial... https://escholarship.org/uc/item/7mn6x3x4 Mon, 18 Oct 2021 00:00:00 +0000 Thomas, Stephen https://escholarship.org/uc/item/7890t6d3 This report summarizes efforts by Winrock International, WM Beaty and Associates, and other Shasta County, California partners to implement hazardous fuel reduction/biomass energy pilot activities in WESTCARB Phase II (2006-10). Wildfire is a significant source of GHG emissions in California and throughout the WESTCARB region. WESTCARB developed methodologies to evaluate, validate and demonstrate the potential of reducing hazardous biomass for biomass energy to contribute to GHG mitigation and adaptation.

This memorandum follows an earlier report prepared by Golder for the WESTCARB team that identified all onshore sedimentary basins in these two states, and provided background information of their physical and hydraulic properties, and provides the first storage estimates. This memorandum follows the guidelines presented in the US Dept. of Energy’s Methodology for Development of Geologic Storage Estimates for Carbon Dioxide (March 2008) for making the estimates https://escholarship.org/uc/item/63c8g8vk Mon, 18 Oct 2021 00:00:00 +0000 Thomas, Stephen https://escholarship.org/uc/item/5qx7m29p This report follows the preliminary assessment of the potential for carbon dioxide (CO2) sequestration in geological settings in Nevada (Price et al. 2005) by more thoroughly evaluating the potentials for reaction of CO2 with naturally occurring minerals and for use of CO2 in enhanced oil recovery (EOR). The results of these two evaluations have been published by the Nevada Bureau of Mines and Geology (Sturmer et al. 2007 for the mineral-reaction work; LaPointe et al. 2007 for the EOR work). This contract report combines those two reports. https://escholarship.org/uc/item/5qx7m29p Mon, 18 Oct 2021 00:00:00 +0000 Price, Jonathan G. Sturmer, Daniel M. LaPointe, Daphne D. Hess, Ronald H. https://escholarship.org/uc/item/5ph7c1kh The Climate Trust conducted an assessment of biochar to determine its appropriateness as a terrestrial carbon sequestration offset project. Biochar is an inert residue created by pyrolysis with the potential to rapidly sequester large amounts of carbon. This report describes what types of biochar projects can most readily qualify as high-quality greenhouse gas offsets for carbon market buyers and investors. The offset quality criteria outlined by the Offset Quality Initiative (2008) are applied to the biochar project type as a whole and to a pilot project at the Thompson Timber log yard in Philomath, Oregon. This report finds that attractive projects must meet the following three criteria. First, projects must use waste biomass that, in the absence of a project, would be left to decompose. Second, projects must produce at least 25,000 metric tons of biochar over 10 years. Third, projects must be able to account for, track, and monitor where all the produced biochar is incorporated... https://escholarship.org/uc/item/5ph7c1kh Mon, 18 Oct 2021 00:00:00 +0000 Weisberg, Peter Delaney, Matt Hawkes, Janet Cathcart, Jim https://escholarship.org/uc/item/5hc547gk The project in this report sought to quantify the baseline of changes in carbon stocks on forest and agricultural lands in Arizona for the 1990s. These baselines provide an estimate of the emissions and removals of greenhouse gases attributable to changes in the use and management of land and are useful for identifying where major opportunities could exist in Arizona for enhancing carbon stocks and/or reducing carbon sources to potentially reduce greenhouse gas emissions.   The analysis revealed that forests were responsible for a net removal of carbon dioxide from the atmosphere of 0.9 million metric tons of carbon dioxide per year (MMTCO2/yr) between 1987 and 1997, and that agricultural lands were responsible for a net emission of 0.04 MMTCO2/yr. On non‐federal lands emissions from forests caused by development were estimated at 0.0145– 0.0152 MMTCO2/yr, and between 1990 and 1996 154,000 acres of forest and rangeland were burned by fires with an estimated emission... https://escholarship.org/uc/item/5hc547gk Mon, 18 Oct 2021 00:00:00 +0000 Pearson, Tim Brown, Sandra Martin, Nicholas Martinuzzi, Sebastian Petrova, Silvia Monroe, Ian Grimland, Sean Dushku, Aaron https://escholarship.org/uc/item/5gv9c890 We have developed a roadmap of CO2 utilization technologies for the California Energy Commission, a state government energy research, policy and permitting agency. The objective of the roadmap is to identify technologies that can make significant contributions to the state's 2020 and 2050 greenhouse gas (CHG) reduction goals. The state of California, under Assembly Bill 32, is committed to achieving reductions to 1990 GHG inventory levels by 2020 and, under Governor's Executive Order S-3-05, to 80 percent below those levels by 2050. The roadmap will guide future R&D investment and policy development for enabling carbon utilization technologies in California. For the purposes of the roadmap, we defined utilization as including technologies that produce a useful product from anthropogenic CO2, or through the processes of capture or sequestration of CO2. Technologies may contribute to reductions directly by permanently sequestering CO2, or indirectly by displacing the use of... https://escholarship.org/uc/item/5gv9c890 Mon, 18 Oct 2021 00:00:00 +0000 Burton, Elizabeth Beyer, John Bourcier, William O'Brien, Kevin Mateer, Niall Reed, John https://escholarship.org/uc/item/585485h9 The objective of this technical report is to analyze the potential for induced seismicity due to a proposed small-scale CO2 injection project in the Montezuma Hills. We reviewed currently available public information, including 32 years of recorded seismic events, locations of mapped faults, and estimates of the stress state of the region. We also reviewed proprietary geological information acquired by Shell, including seismic reflection imaging in the area, and found that the data and interpretations used by Shell are appropriate and satisfactory for the purpose of this report. https://escholarship.org/uc/item/585485h9 Mon, 18 Oct 2021 00:00:00 +0000 Myer, Larry Chiaramonte, Laura Daley, Thomas Wilson, Daniel Foxall, William Beyer, John Henry https://escholarship.org/uc/item/57g7w24m Hybrid poplar (Populus spp.), a short rotation woody crop, is of growing interest in the West Coast States of California, Oregon and Washington. This increased interest has been driven in recent years by hybrid poplar’s potential as a bioenergy crop or multiple wood products crop in combination with the potential revenue from carbon credits. This report aims to identify eligible lands within the West Coast States for the planting of hybrid poplar crops using a geographic information System (GIS) framework. . The eligible lands will be evaluated for their suitability based on a spatial analysis of environmental variables (datasets) that best predict the growth and productivity of hybrid poplar. The resulting suitability map is then analyzed against current research on the growth and productivity of hybrid poplar under different site conditions, which can then be related to carbon sequestration. The results showed that California has the most eligible land with around 14 million... https://escholarship.org/uc/item/57g7w24m Mon, 18 Oct 2021 00:00:00 +0000 Netzer, M.

The roadmap reviews and categorizes the known usage technologies currently in use or under development. Uses of carbon dioxide range from well‐developed applications, such as enhanced oil recovery, to much less mature technologies, such as the use of carbon dioxide to produce fine chemicals, chemical feedstocks, working fluids for energy‐related technologies, and building materials.  This roadmap outlines various attributes of technologies such as technology maturity and readiness, the amount of carbon dioxide that would be consumed or used if fully deployed, technology gaps and barriers to full deployment, and the companies or organizations pursuing development of the technologies. This information is then used to highlight technological advances... https://escholarship.org/uc/item/4kp9x04j Mon, 18 Oct 2021 00:00:00 +0000 Burton, Elizabeth O'Brien, Kevin Bourcier, William Mateer, Niall https://escholarship.org/uc/item/4240468x Over the last decade, many energy experts have supported carbon sequestration as a viable technological response to climate change. Given the potential importance of sequestration in US energy policy, what might explain the views of communities that may be directly impacted by the siting of this technology? To answer this question, we conducted focus groups in two communities who were potentially pilot project sites for California's DOE-funded West Coast Regional Partnership (WESTCARB). We find that communities want a voice in defining the risks to be mitigated as well as the justice of the procedures by which the technology is implemented. We argue that a community's sense of empowerment is key to understanding its range of carbon sequestration opinions, where 'empowerment' includes the ability to mitigate community-defined risks of the technology. This sense of empowerment protects the community against the downside risk of government or corporate neglect, a risk that is rarely... https://escholarship.org/uc/item/4240468x Mon, 18 Oct 2021 00:00:00 +0000 Wong-Parodi, Gabrielle Ray, Isha https://escholarship.org/uc/item/3z3908w5 Background Reports for the California Carbon Capture and Storage Review Panel https://escholarship.org/uc/item/3z3908w5 Mon, 18 Oct 2021 00:00:00 +0000 California Carbon Capture and Storage Review Panel https://escholarship.org/uc/item/3tp538q9 Carbon capture, utilization, and storage (CCUS) is an important technology for greenhouse gas reduction worldwide, and it may be a critical component to enable California to meet its greenhouse gas emissions reduction goals. CCUS is a suite of different types of technologies used to capture carbon dioxide emissions from power plants or large industrial point sources and use this captured carbon dioxide for various purposes including storage, and injecting in rock formations deep underground. Technologies for measuring and monitoring carbon dioxide in the subsurface or in surface facilities also are part of this suite. Because of the complexity and diversity of CCUS technologies, there are numerous challenges to its deployment. The elements to undertaking a CCUS project include both technical and nontechnical—reducing the risks associated with these elements are essential to assuring CCUS is an effective and economic mitigation technology. The greatest risks are associated with... https://escholarship.org/uc/item/3tp538q9 Mon, 18 Oct 2021 00:00:00 +0000 Burton, Elizabeth Beyer, John Mateer, Niall https://escholarship.org/uc/item/3rq2g4sg While California has been at the forefront in adopting an aggressive climate change mitigation policy, it has taken a more measured and tentative approach toward creating an enabling policy and a regulatory framework for carbon capture, utilization and sequestration (CCUS) technologies to contribute to greenhouse gas (GHG) reductions. In 2005, Governor's Executive Order S-3-05 required that California reduce GHG emissions to 1990 levels by 2020 and to 80% below 1990 levels by 2050. In 2006, State Assembly Bill 32 codified the 2020 goal into law. In 2006, the California Legislature required two California agencies, the California Energy Commission and the Department of Conservation, to produce a report recommending how the state could facilitate commercial adoption of geologic sequestration from industrial sources. In 2010, three state agencies, the Energy Commission, Public Utilities Commission, and Air Resources Board, convened the California Carbon Capture and Storage Review... https://escholarship.org/uc/item/3rq2g4sg Mon, 18 Oct 2021 00:00:00 +0000 Burton, Elizabeth Mateer, Niall Beyer, John https://escholarship.org/uc/item/3g35k5gf The Bascom Pacific Conservation Forestry Project was initiated as part of the West Coast Regional Carbon Sequestration Partnersthip (WESTCARB) in order to demonstrate how the baseline and project activities associated with the conservation-based management of a commercially productive forestland site in northern California would be interpreted and projected if a carbon dioxide emissions reductions project were undertaken in accordance with version 2.1 of the Forest Project Protocol of the California Climate Action Registry (now the Climate Action Reserve). After measuring the initial forest carbon stocks on the Bascom Pacific Forest, project activities based on the forest management guidelines outlined in the conservation easement on the property were identified that would create emissions reductions on the project site relative to a baseline scenario based on harvesting the greatest amount of timber feasible and practicable under applicable forest laws.

Passero, M. https://escholarship.org/uc/item/39c3883f This report summarizes efforts by Winrock International and the WESTCARB Fire Panel to develop a methodology for estimating greenhouse gas (GHG) benefits of project activities to reduce emissions from wildland fires in low to mid elevation mixed conifer forests. These efforts focused on low to mid elevation mixed conifer forests and included a conceptual framework developed to aid in determining the full impacts of hazardous fuels treatments, four workshops with carbon and fire experts, numerous consultant activities, and field measurements of hazardous fuels treatments in Shasta County, California and Lake County, Oregon. The task of developing a rigorous methodology to quantify baseline emissions from wildland fires and emission reductions attributable to fuel reduction is complex due to the methodological challenges of modeling fire behavior and emissions, the relatively low annual risk of fire for any given potential project location, and the emissions resulting from fuels... https://escholarship.org/uc/item/39c3883f Mon, 18 Oct 2021 00:00:00 +0000 Pearson, Tim Goslee, Katie Brown, Sandra https://escholarship.org/uc/item/35r8w5qf West Coast Regional Carbon Sequestration Partnership (WESTCARB) Down-Select Report for Task 7: The King Island Characterization Well at King Island, San Joaquin County, California. https://escholarship.org/uc/item/35r8w5qf Mon, 18 Oct 2021 00:00:00 +0000 Burton, Elizabeth, Lawrence Berkeley National Laboratory Beyer, John Henry, Lawrence Berkeley National Laboratory Mateer, Niall, California Institute for Energy & Environment, Myer, Larry, Leonardo Technologies, Inc Trautz, Robert, Electric Power Research Institute Wagoner, Jeffrey, Lawrence Livermore National Laboratory https://escholarship.org/uc/item/30z1r87m In Arizona, riparian areas are important because of the limited amount of water and rapid population growth, that leads to the need for better management of riparian areas. We use PATHDISTANCE spatial model, incorporating rivers, water bodies, slope and elevation to model the extent of potential riparian areas in Arizona. We examined the geophysical potential of landform, rock formation and soil type factors for four native riparian woody vegetation types: cottonwood/willow, conifer/oak, mesquite and mixed broadleaf. To identify the suitable area for afforestation with these native riparian tree species, we analyzed the geophysical potential across the shrub/scrub land cover class (NLCD 2001) for three elevation strata. Total area identified for afforestation was estimated per native riparian tree species and potential carbon sequestration for 20, 40 and 80 year periods was estimated based on field carbon data collected along the Lower Colorado River. The analysis showed that... https://escholarship.org/uc/item/30z1r87m Mon, 18 Oct 2021 00:00:00 +0000 Petrova, Silvia Pearson, Tim Goslee, Katie Brown, Sandra https://escholarship.org/uc/item/2t61h2qq This project provides two case studies of improved forest management and reforestation projects using version 3.1 of the Climate Action Reserve (CAR) forest protocol. Public and private lands are considered as separate scenarios. The baselines, project activity and Certified Reserve Tonnes (CRTs) were calculated for 100‐year time periods. An economic analysis is provided for each scenario. A fire risk modeling analysis was also conducted. The reforestation projects produced net CRTs of 118 to 216 tonnes per acre of CO2e, but were not economically feasible without subsidy. Buffer pools were 10% to 12% on private lands and 18% to 20% on public lands. The use of the improved forest management type on public lands was not feasible. The improved forest management projects produced net CRTs of from 162 to 178 tonnes per acre of CO2e. An economic analysis showed that an improved forest management project, where the initial carbon stocks were well above the assessment area mean, yielded... https://escholarship.org/uc/item/2t61h2qq Mon, 18 Oct 2021 00:00:00 +0000 Richards, Timothy A. Wickizer, Doug https://escholarship.org/uc/item/1tn8n7gq This toolkit includes a series of presentations that can be used for educational purposes to describe the basics of forest carbon projects. These presentations were developed as a result of years of experience working on forest carbon projects domestically and internationally, and in particular, from experience working in Shasta County as a part of the WESTCARB project. Much of the information they contain is the result of lessons learned in Shasta County.  The presentations are intended to give an overview and provide a basic foundation of knowledge; they are not intended to prepare individuals to develop a forest carbon project from start to finish. If individuals or organizations have further interest in learning about or pursuing a forest carbon project, they should contact a forester, project developer or other specialist who has detailed knowledge of and experience in terrestrial carbon projects and markets. https://escholarship.org/uc/item/1tn8n7gq Mon, 18 Oct 2021 00:00:00 +0000 Goslee, Katie Bryan, Leslie Rynearson, Bob Martin, Nicholas https://escholarship.org/uc/item/1qq3m68d WESTCARB and C6 Resources are partners in a CO2 injection project in the Montezuma Hills, 80 km (50 mi) northeast of San Francisco, CA. Through a phased process that involves drilling an appraisal well and injecting CO2 on a small-scale, along with thorough analysis of data and modeling of the system, the goal of the project is to assess the deep geologic formations in the area for Geologic Carbon Sequestration (GCS), and if favorable, inject CO2 currently emitted to the atmosphere from nearby refinery facilities at industrial scales on the order of 1 million tons of CO2 per year. The deep geology at the site is considered very favorable for GCS by virtue of the numerous sandstone formations which are potentially capable of storing large amounts of CO2 and which are vertically separated by thick shale formations that prevent CO2 from migrating upward. This general geologic environment is a proven trap for natural gas over geologic time as evidenced by the nearby Rio Vista Gas... https://escholarship.org/uc/item/1qq3m68d Mon, 18 Oct 2021 00:00:00 +0000 Oldenburg, Curtis Jordan, Preston Mazzoldi, Alberto Wagoner, Jeff Bryant, Steven Nicot, Jean-Phillipe https://escholarship.org/uc/item/1np0n59w Riparian forests are crucial ecosystems linking the aquatic and the terrestrial environment. As a result, these riverine systems process large fluxes of energy, nutrients and life at various spatial and temporal scales. This project idea is for the revegetation of approximately 2,634 acres of riparian lands along the middle and lower reaches of the Santa Cruz River in the U.S. Five different properties were chosen for the implementation of this project. The revegetation project would generate a wide array of social and environmental benefits, such as: carbon sequestration, maintenance of water quality and quantity, fish and wildlife habitat enhancement, and aesthetics and human recreation improvement. In terms of sequestered carbon, the project would result in the uptake of as much as 150,000 tons of CO2e from the atmosphere by 2050. Unfortunately, the implementation of this project was considered unfeasible in economic terms.

As a result of a rapidly growing population, the risk of conversion is especially high in Puget Sound’s watersheds. The objective of this study was to develop a regional characterization study for Washington State that defines residential development as it is implemented in the Puget Sound region to estimate the emissions associated with conversion of forested land for residential development. https://escholarship.org/uc/item/17q6q5jp Mon, 18 Oct 2021 00:00:00 +0000 Swails, E. Pearson, Tim Netzer, M. Goslee, K. Brown, S. https://escholarship.org/uc/item/13g526j2 This report’s goal is to quantify the baseline of changes in carbon stocks on forest and range lands in California for the decade of the 1990s. The focus here is on carbon but first approximation estimates are also given for non-CO2 greenhouse gases (GHGs) where appropriate. Baselines provide an estimate of the emissions and removals of greenhouse gases due to changes in the use and management of land. In addition they are useful for identifying where, within the landscape of California, major opportunities could exist for enhancing carbon stocks and/or reducing carbon sources to potentially mitigate greenhouse gas emissions. The 2002 California Energy Commission report1 estimated the emissions and removals of GHGs from all economic sectors of the State for the period 1990–1999, generally at one-year intervals. However, the sections of the Energy Commission’s 2002 report on the forest and rangeland sectors were incomplete and did not include all the changes taking place on these... https://escholarship.org/uc/item/13g526j2 Mon, 18 Oct 2021 00:00:00 +0000 Pearson, Tim Brown, Sandra Netzer, M. https://escholarship.org/uc/item/1268m1mp Winrock International evaluated the potential for terrestrial carbon sequestration through afforestation in Shasta County, California.  The report presents suitability of rangelands for afforestation, potential carbon accumulation, total costs, and potential carbon supply, and also includes spatially explicit analyses illustrating attractive regions for afforestation within the county and the range of afforestation costs. Researchers determined that afforestation of Shasta County rangelands could result in the sequestration of about 17.7 million tons of carbon (t C) after 20 years at a cost of less than $20/t C ($5.45/ton of carbon dioxide [t CO2]) or about 57.6 million tons of carbon after 80 years at a cost of less than $10/t C ($2.7/t CO2).  This opportunity, which will be tested and validated through pilot projects in Shasta County under the U.S. Department of Energy‐funded West Coast Regional Carbon Sequestration Partnership (WESTCARB)—Phase II, could... https://escholarship.org/uc/item/1268m1mp Mon, 18 Oct 2021 00:00:00 +0000 Martin, Nicholas Petrova, Silvia Brown, Sandra Pearson, Tim Kadyszewski, J. https://escholarship.org/uc/item/1056426n As part of the West Coast Regional Carbon Sequestration Partnership (WESTCARB), Advanced Resources International, Inc. evaluated the CO2 storage potential of deep coal seams and interbedded sandstone saline aquifers in the Centralia-Chehalis basin of west-central Washington State. These reservoirs could be used for long-term geologic storage of CO2 captured from TransAlta’s 1,404-MW coal-fired steam power plant near Centralia, Washington. https://escholarship.org/uc/item/1056426n Mon, 18 Oct 2021 00:00:00 +0000 Stevens, Scott https://escholarship.org/uc/item/0hz7301s Fuel treatments involve the removal of biomass from targeted areas in the forested landscape to reduce the risk of uncharacteristically severe wildfires caused by excess biomass in the forest. This report describes a landscape-scale case study in southern central Oregon that modeled the impact of fuel treatments on wildfire behavior and associated carbon dioxide emissions and assesses the project’s ability to generate carbon offsets that meet the quality criteria identified by the Offset Quality Initiative. The report makes two primary findings. The first is that the case study is likely a carbon-neutral project, meaning that few or no offsets would result from the project activity. The second is that, while this project type could generate quality offsets, the adoption rate would likely be low due to the current inability to implement quality offset projects on federal lands and the expense of the activities required to ensure that the carbon benefit is real and permanent.

These perspectives were analyzed in the context of each community’s history and its social and economic characteristics. The results were considered for their insights into specific concerns within each region, as well as to assess inter-region commonalities. In all cases, factors such as past experience with government, existing low socioeconomic status, desire for compensation, and/or perceived benefit to the community were of greater concern than the concern about the risks of the technology itself. This paper discusses the findings from the joint review of the focus groups and the potential lessons for application to CCS deployment. https://escholarship.org/uc/item/0cd4g4s8 Mon, 18 Oct 2021 00:00:00 +0000 Bradbury, Judith, Pacific Northwest National Laboratory Ray, Isha, Energy & Resources Group, University of California, Berkeley Peterson, Tarla, Texas A & M University College Station Wade, Sarah, AJW, Inc. Wong-Parodi, Gabrielle, Energy & Resources Group, University of California, Berkeley Feldpausch, Andrea https://escholarship.org/uc/item/07z0c8c8 Environmental non-governmental organizations (NGOs) have been influential in shaping public perceptions of environmental problems, their causes and potential solutions. Over the last decade, carbon capture and storage (CCS) has emerged as a potentially important technological response to climate change. In this paper we investigate how leading US NGOs perceive geologic sequestration, a potentially controversial part of CCS. We examine how and why their perceptions and strategies might differ, and if and how they plan to shape public perceptions of geologic sequestration. We approach these questions through semi-structured interviews with representatives from a range of NGOs, supplemented by content analysis of their documents. We find that while all the NGOs are committed to combating climate change, their views on CCS as a mitigation strategy vary considerably. We find that these views are correlated with NGOs' histories of activism and advocacy, as well as with their sources... https://escholarship.org/uc/item/07z0c8c8 Mon, 18 Oct 2021 00:00:00 +0000 Wong-Parodi, Gabrielle Ray, Isha Farrell, Alexander E.
