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.

The State of the State Department and American Diplomacy

| Jan. 03, 2019

During the Trump administration, the usual ways of conducting diplomacy have been upended. Many positions in the State Department have never been filled, and meetings with foreign leaders such as Kim Jong-un and Vladimir Putin have been undertaken with little advance planning. What effect are these changes having now, and how will they affect ongoing relationships between the United States and its allies and adversaries?

| 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.

| Oct. 20, 2017

The presidency of Donald Trump is challenging nothing less than the foundation of American democracy, says R. Nicholas Burns, a former U.S. ambassador and undersecretary of state for President George W. Bush. “That generation between 1945 and the last couple years produced, despite all the problems we have, a stable world,” said Burns. “And I am now worried.”
