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.

Addressing the Nuclear Ban Treaty

| Apr. 16, 2019

The Nuclear Nonproliferation Treaty (NPT), a bedrock of international security, had the 50-year anniversary of its signing in 2018. While the existence of the treaty has not been able to prevent a handful of states from seeking nuclear weapons, for half a century the NPT has promoted norms of nuclear nonproliferation and disarmament. Only nine states possess nuclear weapons today, far below the number predicted early in the nuclear age. Nonetheless, a second nuclear treaty, adopted in 2017, represents a significant and growing crack in the foundation of the NPT and suggests that relations among its members need to change if the treaty is going to survive another 50 years.

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.

Preventing the Next Attack: A Strategy for the War on Terrorism

| Oct. 16, 2017

Today, the terrorist threat looks much different than it did right before 9/11. The U.S. counterterrorism community has dramatically ramped up its intelligence capabilities. Determined to “connect the dots” in the future, the U.S. government created new agencies and instituted a new paradigm for intelligence—share by rule, withhold by exception—and set up a slew of “fusion centers” and joint task forces to foster interagency cooperation. Borders were hardened, cockpit doors reinforced, and watch lists created. In Afghanistan, the United States overthrew the Taliban regime, which was hosting al Qaeda. Today, despite recent Taliban gains, al Qaeda still does not enjoy free rein in the country. In Iraq and Syria, al Qaeda’s offshoot, the Islamic State (or ISIS), is on the run, thanks to the work of a global coalition assembled in 2014 and U.S.-led air strikes and special operations raids. The group’s Iraqi capital of Mosul fell in July, and its Syrian stronghold in Raqqa is almost certain to follow. Owing to the relentless pressure that the United States and its allies have placed on terrorists’ safe havens, the threat of a complex and catastrophic attack emanating from abroad—although not gone—has diminished. At the same time, however, the threat from homegrown and so called lone-wolf terrorism has increased.

Burns : « Il renie soixante-dix and de diplomatie » (Burns: "He rejects seventy years of diplomacy")

| Feb. 02, 2017

In an interview with Amin Arefi of French magazine Le Point, Ambassador (ret.) Nicholas Burns reflects on the first ten days of the Trump administration and the trajectory of American foreign policy going forward. Burns explains the fundamental differences between Donald Trump and George W. Bush, and the  worrying implications of Trump's indifference towards the US-backed system of alliances that has upheld the liberal world order for the past seven decades.

Long Lines and Disasters: The TSA in a Time of Troubles

| May 20, 2016

"The way TSA and certainly security experts like me think about security is that we talk about layered security: That is, what you want is enough layers. None of them are perfect; everyone is willing to admit that. You might secure some doors and not others. But you put enough layers in those access points for violence to become a little bit more difficult."

Energy decisions reframed as justice and ethical concerns

| 6 May 2016

Many energy consumers, and even analysts and policymakers, confront and frame energy and climate risks in a moral vacuum, rarely incorporating broader social justice concerns. Here, to remedy this gap, we investigate how concepts from justice and ethics can inform energy decision-making by reframing five energy problems — nuclear waste, involuntary resettlement, energy pollution, energy poverty and climate change — as pressing justice concerns.

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.
