Keystone XL Pipeline Project: Key Issues
[Excerpt] This report describes the Keystone XL Project as it is proposed in the 2012 Presidential Permit application and the process that the State Department is obligated to complete to issue or deny that application. To the extent that they may affect the State Department’s decision to issue or deny the current permit application, this report discusses selected issues related to the project proposed in 2008 and issues that have arisen since the State Department denied the initial permit application in 2012. This report also summarizes key arguments that have been raised, both for and against the pipeline, by the pipeline’s developers, state and federal agencies, environmental groups, private property owners, and other stakeholders. Finally, the report discusses the constitutional basis for the State Department’s authority to issue a Presidential Permit, and opponents’ possible challenges to this authority

Keystone XL Pipeline Project: Key Issues
[Excerpt] This report describes the Keystone XL pipeline proposal and the process required for federal approval. It summarizes key arguments for and against the pipeline put forth by the pipeline’s developers, federal agencies, environmental groups, and other stakeholders. Finally, the report reviews the constitutional basis for the State Department’s authority to issue a Presidential Permit, and opponents’ possible challenges to this authority
A Review of Flywheel Energy Storage System Technologies and Their Applications
Energy storage systems (ESS) provide a means for improving the efficiency of electrical systems when there are imbalances between supply and demand. Additionally, they are a key element for improving the stability and quality of electrical networks. They add flexibility into the electrical system by mitigating the supply intermittency, recently made worse by an increased penetration of renewable generation. One energy storage technology now arousing great interest is the flywheel energy storage systems (FESS), since this technology can offer many advantages as an energy storage solution over the alternatives. Flywheels have attributes of a high cycle life, long operational life, high round-trip efficiency, high power density, low environmental impact, and can store megajoule (MJ) levels of energy with no upper limit when configured in banks. This paper presents a critical review of FESS in regards to its main components and applications, an approach not captured in earlier reviews. Additionally, earlier reviews do not include the most recent literature in this fast-moving field. A description of the flywheel structure and its main components is provided, and different types of electric machines, power electronics converter topologies, and bearing systems for use in flywheel storage systems are discussed. The main applications of FESS are explained and commercially available flywheel prototypes for each application are described. The paper concludes with recommendations for future research

Keeping America's Pipelines Safe and Secure: Key Issues for Congress
Nearly half a million miles of pipeline transporting natural gas, oil, and other hazardous liquids crisscross the United States. While an efficient and fundamentally safe means of transport, many pipelines carry materials with the potential to cause public injury and environmental damage. The
nation's pipeline networks are also widespread and vulnerable to accidents and terrorist attack. As it oversees the federal pipeline safety program and the federal role in pipeline security, Congress may wish to assess how the various elements of U.S. pipeline safety and security fit together in the nation's overall strategy to protect transportation infrastructure. Pipeline safety and security necessarily involve many groups: federal agencies, oil and gas pipeline associations, large and small pipeline operators, and local communities. Reviewing how these groups work
together to achieve common goals could be an oversight challenge for Congress

Pipeline Security: An Overview of Federal Activities and Current Policy Issues
Recommended from our members
110th Congress
This report discusses the United States pipeline networks and their security. The Surface Transportation and Rail Security Act of 2007 (S. 184) would require federal plans for critical pipeline security and incident recovery, and would mandate pipeline security inspections and enforcement
Security: Collective good or commodity?
This is the author's accepted manuscript. The final published article is available from the link below. Copyright @ 2008 Sage.The state monopoly on the legitimate use of violence in Europe and North America has been central to the development of security as a collective good. Not only has it institutionalized the state as the prime national and international security provider, it has helped to reduce the threat from other actors by either prohibiting or limiting their use of violence. The recent growth of the private security industry appears to undermine this view. Not only are private security firms proliferating at the national level; private military companies are also taking over an increasing range of military functions in both national defence and international interventions. This article seeks to provide an examination of the theoretical and practical implications of the shift from states to markets in the provision of security. Specifically, it discusses how the conceptualization of security as a commodity rather than a collective good affects the meaning and implementation of security in Western democracies.ESR
