Deploying coal-bioenergy gasification systems with carbon capture and storage (CBECCS) provides a promising opportunity for China to realize its carbon mitigation and air pollution abatement goals simultaneously. The authors conducted a comprehensive assessment of CBECCS technology for China, with a focus on plant and fuel configurations (e.g., biomass ratios) and economics, as well as CO2 and greenhouse gas emissions and cobenefits for air quality.

Buying Allies: Payment Practices in Multilateral Military Coalition-Building

    Author:
  • Marina E. Henke
| Spring 2019

Many states have been paid to join multilateral military coalitions. These payments are largely covered by “pivotal states”—those that care the most about an operation’s success—and take the form of deployment subsidies and political side deals to attract critical contributors to the mission.

Governments as Partners: The Role of Alliances in U.S. Cleantech Startup Innovation

Accelerating innovation in clean energy technologies is a policy priority for governments around the world aiming to mitigate climate change and to provide affordable energy. Most research has focused on the role of governments financing R&D and steering market demand, but there is a more limited understanding of the role of direct government interactions with startups across all sectors. The authors  propose and evaluate the value-creation mechanisms of network resources from different types of partners for startups, highlighting the unique resources of government partners for cleantech startups.

The Demographic Transition Theory of War: Why Young Societies Are Conflict Prone and Old Societies Are the Most Peaceful

| Winter 2018/19

Many states with young populations are growing old fast. If states with older populations engage in violent conflict less frequently than states with large numbers of young people, the implications for the international order could be significant.

Escalation through Entanglement: How the Vulnerability of Command-and-Control Systems Raises the Risks of an Inadvertent Nuclear War

    Author:
  • James Acton
| Summer 2018

The risks of nuclear escalation are greater than ever given the possibility of misinterpreted cyber espionage and military strikes against early warning systems.

A Process for Capturing CO2 from the Atmosphere

    Authors:
  • Geoffrey Holmes
  • David St. Angelo
  • Kenton Heidel
| 2018

The authors describe a process for capturing CO2 from the atmosphere in an industrial plant. The design captures ∼1 Mt-CO2/year in a continuous process using an aqueous KOH sorbent coupled to a calcium caustic recovery loop. They describe the design rationale, summarize performance of the major unit operations, and provide a capital cost breakdown developed with an independent consulting engineering firm. They report results from a pilot plant that provides data on performance of the major unit operations.

Simultaneous Pursuit of Discovery and Invention in the US Department of Energy

There is a sharp boundary between basic and applied research in the organizational structure of the US Department of Energy (DOE). In this work, the authors consider a branch of DOE that was designed to operate across this boundary: the Advanced Research Projects Agency — Energy (ARPA-E). They hypothesize that much of energy research cannot be neatly categorized as basic or applied and is more productive outside of the confines of the basic/applied dichotomy; ARPA-E provides an opportunity to test that hypothesis.

Review of The Army and Democracy: Military Politics in Pakistan by Aqil Shah

| 2017

"This book serves as an invaluable resource for scholars, analysts and policymakers seeking to understand the precise nature of military influence in Pakistan's political development, and evaluate its prospects for deepening democratisation. The volume traces the origins, perpetuation, and consequences of military dominance in the evolution of Pakistan's national politics and institutions."
