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.

Why China Has Not Caught Up Yet: Military-Technological Superiority, Systems Integration, and the Challenges of Imitation, Reverse Engineering, and Cyber-Espionage

| Winter 2018/19

The extraordinary complexity of today’s advanced weapons systems has significantly reduced the ability of states to imitate other states’ military technology. Consequently, U.S. rivals such as China will continue to struggle to develop indigenous capabilities that can match those of the United States.

Solving the Jurisdictional Conundrum: How U.S. Enforcement Agencies Target Overseas Illicit Procurement Networks Using Civil Courts

| September 2018

Over the past two decades, the United States has increasingly turned to targeted sanctions and export restrictions, such as those imposed against Iran and North Korea, in order to curb the spread of weapons of mass destruction. One vexing problem, however, is how to contend with jurisdictional hurdles when the violations occur overseas, in countries that are unable or unwilling to assist US enforcement efforts. To solve this problem, US prosecutors are turning to strategies with significant extraterritorial implications—that is, exercising legal authority beyond national borders. One such tool is to use civil legal procedures to seize assets linked to sanctions or export-control violations in jurisdictions that lack cooperative arrangements with US enforcement agencies. While this may be an attractive strategy to bolster enforcement efforts against overseas illicit procurement, using such tools is not without consequence. This article explores the political, legal, and technical implications of enforcing extraterritorial controls against overseas non-state actors by exploring the recent uses of civil-asset forfeiture against Iranian and North Korean procurement networks.

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.

The Case for Economic Development Through Sovereign Investment: A Paradox of Scarcity?

| Apr. 14, 2018

Sovereign wealth funds (SWFs) have traditionally been created to recycle excess reserves from natural resource or non‐commodity revenues. However, in recent years funds are being established under conditions of capital scarcity with objectives to contribute domestic economic development, often through the buildout of national infrastructure programs. Such trends in new fund creation represent a fundamental shift in the sovereign wealth fund paradigm and raise serious questions about how these entities are to be capitalized and also the implications of capitalization models on their sustainability. This study examines the recent evolution of SWF models focused on economic development. Its analytic focus is drawn, in particular, to countries that are neither endowed with oil wealth, nor otherwise enjoy export surpluses to be used to capitalize a development‐oriented SWF. While this study is relevant to and expands the scope of the broad literature on SWFs, its specific contribution is as a focused analysis of how SWF funding sources impact achieving long‐term financial and socio‐economic development objectives.

Negotiating the "Iran Talks" in Tehran: The Iranian Drivers that Shaped the Joint Comprehensive Plan of Action

| Forthcoming

When Iran and the world powers resumed negotiations over Tehran's controversial nuclear program after a seven-year lull, Iran's hardline President Mahmoud Ahmadinejad was approaching the end of his second and last term. During that time, little progress was made. After the election of the moderate Hassan Rouhani to the presidency, the talks resumed decisively. Rouhani and his team were in an ideal position to strike a deal, as they were afforded cross-party support supplying them with political will and political capital.

Tomcat and Mouse: Iranian Illicit Procurement of U.S. Legacy Military Technologies, 1979–2016

| Autumn 2017

Since the 1979 revolution, Iran has sought to illicitly procure parts for the U.S. origin fighter aircraft sold to the country under the rule of the Shah. The U.S. has taken steps to quash this trade—these efforts have constituted a relatively large proportion of U.S. export control enforcement over the past near-to-four decades.

Americans Aren’t as Averse to Using Nuclear Weapons as You Might Think

With U.S.-North Korea tensions heightened after weeks of fiery and furious rhetoric from President Trump and Kim Jong-un—pushing the world closer to nuclear conflict than it has been in decades—it’s worth taking a breath to consider what forces have kept the world’s nuclear-armed states from irradiating and annihilating each other in a shower of bombs.
