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.

North Korea’s Missile Programme and Supply-Side Controls: Lessons for Countering Illicit Procurement

| Oct. 17, 2018

Despite one of the most extensive sanctions regimes in history, including an embargo on missile technologies, North Korea has taken huge steps forward in its ballistic missile programme. Daniel Salisbury explores the limitations of, and challenges of implementing, supply-side approaches to missile nonproliferation. Considering North Korea’s recent progress and efforts to evade sanctions, the article highlights the continuing need to strengthen efforts to counter illicit trade in missile-related technologies.

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.

New Ways to Detect Nuclear Misbehavior

| Jan. 08, 2018

If we had the technology to detect nuclear materials remotely it could help deter smuggling and make it easier to monitor international nuclear agreements. Several recent breakthroughs, if followed up with continued research and funding, could deliver on this promise. They include technological advances in x-ray and neutron radiography; a method that measures how plasma breaks down when exposed to a radioactive source; and developments in antineutrino detection. While all require more development and testing, they are important steps as the global need for ways to detect nuclear materials grows.

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.

Expert Views — and Disagreements — About the Potential of Energy Technology R&D

| June 2016

In order to make R&D funding decisions to meet particular goals, such as mitigating climate change or improving energy security, or to estimate the social returns to R&D, policy makers need to combine the information provided in this study on cost reduction potentials with an analysis of the macroeconomic implications of these technological changes. The authors conclude with recommendations for future directions on energy expert elicitations.

How Much Bulk Energy Storage is Needed to Decarbonize Electricity?

| 2015

High cost and technical immaturity of bulk (multi-hour) electricity storage (BES) systems are often cited as major hurdles to increasing the penetration of intermittent renewables. The authors use a simple model to assess the economics of BES under carbon emissions constraints.

Technology Innovation and Energy

Energy technology innovation is the key to driving the technological changes that are necessary to meet the challenge of mitigating energy-related greenhouse gas emissions to avoid 'dangerous climate change.' Success in innovation requires the enhancement of public investment in the innovation process, the creation of markets for low-carbon technologies through stronger climate policies, and a continued focus on energy access and equity.

Preparing to Ramp up Large-scale CCS Demonstrations: An Engineering-economic Assessment of CO2 Pipeline Transportation in China

| July 2011

An integrated carbon dioxide (CO2) capture and storage (CCS) system requires safe and cost-efficient solutions for transportation of the CO2 from the capturing facility to the location of storage. While growing efforts in China are underway to understand CO2 capture and storage, comparatively less attention has been paid to CO2 transportation issues. Also, to the best of our knowledge, there are no publicly available China-specific cost models for CO2 pipeline transportation that have been published in peer-reviewed journals. This paper has been developed to determine a first-order estimate of China's cost of onshore CO2 pipeline transportation.
