- Carbon Sequestration as a Greenhouse Gas Mitigation Strategy: A Comparative Assessment of Options
The President's Global Climate Change Initiative supports the reduction of greenhouse gas intensity (the ratio of greenhouse gas emissions to economic output) through technology innovation and market mechanisms. Over the next 10 years, the Administration's goal is to reduce greenhouse gas intensity by 18 percent. This reduction can be achieved by a combination of three technology options: (1) by making energy systems more efficient; (2) by increasing the contribution of renewables, nuclear power, and natural gas to the nation's energy mix; and, (3) by capturing and sequestering CO2, methane, and other greenhouse gases that would normally be released to the atmosphere.
The purpose of this symposium is to explore each of these approaches as a contributor to a mitigation strategy, with a focus on carbon sequestration. Issues associated with these three approaches will be examined in the context of social and economic considerations that determine acceptability of technological options. There are many questions surrounding this issue - questions that are scientific, economic, and ethical. Our goal is to take a critical look at each mitigation pathway and evaluate it based on our current understanding of climate change mitigation science. Carbon sequestration is an emerging technology area, and the National Energy Technology Laboratory has taken a leadership role in carbon sequestration science and technology development.
- Climate Change Mitigation Strategy: Technical Challenges for Carbon Sequestration
Global climate change is the object of intense social and political interest. While much of the related science is focused on determining the size of the warming effect, a growing number of researchers are focusing on how to decrease anthropogenic emissions of greenhouse gases. Because we will continue to rely on fossil fuels for at least the next few decades, carbon sequestration is likely to become a necessary part of any mitigation scheme.
Carbon sequestration is a technique that consists of capturing carbon dioxide from man-made sources and permanently storing it somewhere other than the atmosphere (e.g., terrestrial (biota), oceanic, or geologic sequestration). Each storage medium has its distinct strengths and weaknesses, from a technical perspective, including implementation cost, storage capacity, and accessibility. A sound policy will involve the use of multiple methods, with each one tailored to the specific CO2 source(s) in a region.
This symposium is designed to discuss the technical issues that must be resolved before carbon sequestration is implemented on a large scale. The speakers were chosen to highlight the strengths and weaknesses of different capture and storage technologies and to describe the major technological hurdles to sequestration involved in each.
