This page is derived from the 2015 National Academies report Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration. It provides a high-level overview of various approaches to carbon dioxide removal and sequestration, as well as associated estimates for cost and rate of capture and/or sequestration.
Our website keeps you up to date on all the climate change related events, reports, and other activities at the National Academies of Sciences, Engineering, and Medicine.
As one of a two-book report, this volume of Climate Intervention discusses CDR, the carbon dioxide removal of greenhouse gas emissions from the atmosphere and sequestration of it in perpetuity. Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration introduces possible CDR approaches and then discusses them in depth. Land management practices, such as low-till agriculture, reforestation and afforestation, ocean iron fertilization, and land-and-ocean-based accelerated weathering, could amplify the rates of processes that are already occurring as part of the natural carbon cycle. Other CDR approaches, such as bioenergy with carbon capture and sequestration, direct air capture and sequestration, and traditional carbon capture and sequestration, seek to capture CO2 from the atmosphere and dispose of it by pumping it underground at high pressure. This book looks at the pros and cons of these options and estimates possible rates of removal and total amounts that might be removed via these methods.
In the past several years, some energy technologies that inject or extract fluid from the Earth, such as oil and gas development and geothermal energy development, have been found or suspected to cause seismic events. Although only a very small fraction of injection and extraction activities among the hundreds of thousands of energy development sites in the United States have induced seismicity at levels noticeable to the public, understanding the potential for inducing felt seismic events and for limiting their occurrence and impacts is desirable for state and federal agencies, industry, and the public at large.
Induced Seismicity Potential in Energy Technologies identifies gaps in knowledge and research needed to advance the understanding of induced seismicity; identify gaps in induced seismic hazard assessment methodologies and the research to close those gaps; and assess options for steps toward best practices with regard to energy development and induced seismicity potential.
Energy touches our lives in countless ways and its costs are felt when we fill up at the gas pump, pay our home heating bills, and keep businesses both large and small running. There are long-term costs as well: to the environment, as natural resources are depleted and pollution contributes to global climate change, and to national security and independence, as many of the world’s current energy sources are increasingly concentrated in geopolitically unstable regions. The country’s challenge is to develop an energy portfolio that addresses these concerns while still providing sufficient, affordable energy reserves for the nation.
America’s Energy Future analyzes the potential of a wide range of technologies for generation, distribution, and conservation of energy. This book considers technologies to increase energy efficiency, coal-fired power generation, nuclear power, renewable energy, oil and natural gas, and alternative transportation fuels. It offers a detailed assessment of the associated impacts and projected costs of implementing each technology and categorizes them into three time frames for implementation.
Novel Approaches to Carbon Management presents ideas raised at a workshop held in 2003 by the National Research Council’s (NRC’s) Committee on Novel Approaches to the Management of Greenhouse Gases from Energy Systems to identify promising lines of research that could lead to currently unforeseen breakthroughs in the management of carbon from energy systems. The information identified by participants in the workshop was intended to inform the U.S. Department of Energy’s (DOE’s) Office of Fossil Energy (FE) in its awarding of grants for new research in carbon management.
Among the many valuable ecosystems services of coastal environments is their ability to take up some of the excess carbon from the atmosphere. This new publication summarizes a workshop that explored the potential to restore and manage coastal habitats, particularly coastal wetlands, as a viable carbon dioxide removal approach (often termed coastal blue carbon). Workshop speakers described their relevant work including the state of knowledge and research needs related to understanding carbon capacity and flux in coastal systems, the processes driving sustainability of coastal wetland carbon storage in the future, potential incentives for coastal blue carbon, and policy and governance challenges.
The workshop was held to inform an ongoing National Academies study, Developing a Research Agenda for Carbon Dioxide Removal and Reliable Sequestration. Other workshop topics in the study, for which proceedings will be produced include terrestrial carbon sequestration, bioenergy with carbon capture, direct air capture, and geologic sequestration.
The final publication of the study will be an expert consensus report that outlines a detailed research and development agenda to assess the benefits, risks, and sustainable scale potential for carbon dioxide removal and sequestration approaches, as well as to increase their commercial viability.
