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.

A Process for Capturing CO2 from the Atmosphere

    Authors:

| 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.

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.

Why the President Needs a Council of Historians

| September 2016

We urge the next president to establish a White House Council of Historical Advisers. Historians made similar recommendations to Presidents Carter and Reagan during their administrations, but nothing ever came of these proposals. Operationally, the Council of Historical Advisers would mirror the Council of Economic Advisers, established after World War II. A chair and two additional members would be appointed by the president to full-time positions, and respond to assignments from him or her. They would be supported by a small professional staff and would be part of the Executive Office of the President.

On Thursday, voters in the U.K. will decide by a simple majority whether to remain in the E.U. during a national referendum known as “Brexit” (a portmanteau of the words British and exit). Over the last month, public opinion polling showed voters evenly split, with the “leave” campaign edging upslightly in recent days. Douglas Alexander is a senior fellow in The Future of Diplomacy Project.The Gazette spoke with Alexander about the upcoming referendum and the potential fallout for the U.K. and Europe.

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.
