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?

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.

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.

The Inside Counsel Revolution

| April 2016

The practical ideal of the modern general counsel is a lawyer-statesperson who is an outstanding technical expert, a wise counselor and an effective leader, and who has a major role assisting the corporation achieve the fundamental goal of global capitalism: the fusion of high performance with high integrity and sound risk management. For the lawyer-statesperson, the first question is: "Is it legal?" But the ultimate question is: "Is it right?"

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.

The Thucydides Trap: Are the U.S. and China Headed for War?

| September 24, 2015

The defining question about global order for this generation is whether China and the United States can escape Thucydides’s Trap. The Greek historian’s metaphor reminds us of the attendant dangers when a rising power rivals a ruling power—as Athens challenged Sparta in ancient Greece, or as Germany did Britain a century ago. Most such contests have ended badly, often for both nations, a team of mine at the Harvard Belfer Center for Science and International Affairs has concluded after analyzing the historical record. In 12 of 16 cases over the past 500 years, the result was war. When the parties avoided war, it required huge, painful adjustments in attitudes and actions on the part not just of the challenger but also the challenged.

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.
