Dangers of Carbon Sequestration Why it Should not Be Used excessively

This article discusses the negative effects of carbon sequestration and why it's not a perfect solution to excessive carbon gas emission problems.

CO2 Transport Versus the 50-State Sequestration Strategy, Pa

Current Administration and congressional climate proposals depend heavily on geological sequestration to reduce CO2 emissions from coal-fired power plants and other major sources and tend to presume that sources in every state will have access to nearby underground storage capacity. This is the second post in a three-part series reviewing obstacles to a 50-state sequestration strategy and suggesting the need for a national infrastructure to support medium to long-range transport of CO2.

Even if additional research and site characterization could resolve geological uncertainties regarding widespread local CO2 storage, companies also will have to overcome the public and political opposition that locally undesirable land use (LULU) energy projects engender. While CO2 sequestration provides important global benefits, local communities are likely to balk at hosting a sequestration project injecting millions of tons of liquid CO2 as a waste product under or near their communities.

The saga of Used Nuclear Fuel Storage at Yucca Mountain in Nevada illustrates the challenge of siting even one nationally-important, but locally-opposed, facility. First identified as the nation’s prospective high-level nuclear waste storage site in 1987 and approved by Congress in 1994, the Yucca Mountain high-level nuclear waste storage facility received over 9 billion dollars in funding through 2008 despite vociferous opposition from local stakeholders and, in some cases, key federal constituencies. In early 2009, the Obama Administration proposed to defund the project. While only Congress can cancel the project, Senate Majority Leader Harry Reid (D-NV) has committed to doing just that. Irrespective of the merits of the decision to defund Yucca, it is a significant setback for the domestic nuclear energy industry, as the reversal leaves the nation twenty years behind in developing a long-term disposal strategy for high-level nuclear waste.

Even relatively innocuous renewable energy projects face siting difficulties. Indeed, the U.S. Chamber of Commerce recently initiated a campaign to document the wide variety of energy projects that have been stopped or delayed across the nation by local opposition. The siting challenge illustrates an important reality check for policymakers and investors: a prospective site may contain optimal subsurface geologic characteristics, but if developers cannot negotiate the local siting process, the technical feasibility of a location is irrelevant.

Siting CCS facilities on federal lands may be one way to reduce the ability of local opposition to stop a project. The Department of Interior has estimated that 5.5 percent of the onshore U.S. CO2 storage capacity is beneath potentially leasable Federal lands. But, federal lands bring limitations of their own. First, federal lands are not uniformly distributed across regions and states, and many areas of the country (e.g., the northeast, southeast and midwest) lack large swaths of federal lands on which facilities could be sited. The disconnect is even more significant when major emissions sources are considered. According to a recent DOE Report, while 65% of emissions come from east of the Mississippi River, 83% to 86% of storage capacity on federal lands lies west of the Mississippi River. In other words, a siting strategy that relies on federal lands for citing will require investment on CO2 transport to match source generation to sequestration capacity.

Second, federal lands are subject to a variety of restrictions and extensive regulatory review requirements on the use of federal lands. Any commercial-scale sequestration funded by federal dollars or constructed on federal lands will be subject, at a minimum, to the environmental review requirements of the National Environmental Policy Act and the historic review requirements of the National Historic Preservation Act. These statutes delay construction schedules, create potential avenues for litigation from opposing parties, and inject risk and expense into large-scale projects. The federal government would also have to determine that the proposed sequestration projects would be consistent with other approved uses for a federal land, a determination that can involve many different federal agencies working through multi-year planning processes.

Whether CCS project developers use federal, state, or privately-owned land for sequestration projects, they will have to demonstrate that their siting choices are safe for the local communities, safe for the local environment, and consistent with the legal standards governing such land-use. While well-funded, well-planned, and well-organized projects will be capable of overcoming these obstacles, such approvals will come at a financial and political cost. Policymakers need to factor in the realistic costs of addressing community concerns and project approvals into their policy calculus if they are to develop a realistic understanding of when, where, and how the U.S. will be able to site the sequestration capacity needed to meet carbon mitigation goals - at a financial and political price that the public will bare.

Geological Sequestration Projects Hitting Public Opposition Wall

Last year, Swedish Company Vattenfall announced its plans to go on-line with a major pilot program to test carbon capture and sequestration at a coal-fired power plant. The company recently acknowledged that permitting snags fueled by local opposition render it unable to commence geologic sequestration of captured CO2. Vattenfall intended to begin capturing CO2 at its 30-megawatt Schwarze Pumpe facility, located in Spremberg, Germany, and sequestering it in the nearby Altmark depleted gas field by March or April 2009. Residents of the host-city, however, have expressed concerns about the safety of geological sequestration, preventing the final permitting approval for the site and creating questions about when - or if - the site could be available for any CCS operations.

Vattenfall’s experience at this project is not an isolated incident. Vattenfall reported delays in obtaining approvals for one of its Danish storage projects pointing, in part, to public opposition by local stakeholders. In June, German news sources reported that activists were protesting plans by electric utility RWE to transport captured CO2 by pipeline from a powerplant near Cologne to a sequestration site on Germany’s North Sea Coast. The Wall Street Journal also reported in April that Royal Dutch Shell had run into challenges siting a sequestration facility in Barendrecht, Netherlands, due to grass roots opposition from local residents.

Public opposition is likely to be a critical strategic and legal consideration for US projects. On Friday, August 21, Battelle, the lead partner in a Midwest Regional Carbon Sequestration Partnership project announced that it was abandoning plans to participate in a $92 million public-private demonstration project to site a geological sequestration project in Western Ohio. While the partner cited only “business reasons” for its decision, the reported public opposition to the project could not have helped.

These setbacks illustrate the significant challenges that the siting and permit-approval process can pose, particularly in the face of public opposition, to an otherwise promising project. This will be particularly true during the early stages of a CCS deployment. US policymakers and investors would do well to watch and learn from these early case studies, and to ensure that they devote the legal, political and community relations resources needed to ensure that proposed projects move forward in a realistic and timely fashion.
