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.

Remarks by Ambassador (ret.) Nicholas Burns: Conference on Versailles 1919-2019

| May 25, 2019

I saw first-hand the value of our alliance with Europe on 9/11 when I was the new American Ambassador to the Alliance.  When we were hit hard in New York and Washington D.C., the allied Ambassadors came to me in Brussels that afternoon to pledge their support for us when we needed them most.  They pledged to invoke the alliance’s collective defense clause—Article 5 of the NATO Treaty—that an attack on one would be considered an attack on all.

New Battleground? China-Europe vs. America-Europe

| May 15, 2019

The policies of the Trump Administration have produced an international alignment, which never existed before: China and Europe (EU) now find themselves on the same side in a global conflict where the American president attacks multilateralism, has withdrawn from major international trade agreements, has unilaterally imposed tariffs, and questioned the validity of the WTO.

What NATO Needs To Do To Live To Its 100th Birthday

| Mar. 14, 2019

Yet as this special report has pointed out, NATO is also deeply troubled. Douglas Lute and Nicholas Burns, two former American ambassadors to NATO, say Donald Trump has “hurtled the alliance into its most worrisome crisis in memory.” The report, “NATO at Seventy,” sets out a daunting array of the challenges it faces.

Russia's Energy Foray into Asia: Implications for U.S. Interests

This essay examines Russia’s growing role in Asia’s energy markets, assesses the implications for the U.S., and examines the claim that closer Sino-Russian energy ties are adding new incentives for a broader strategic alignment.

Harvard-Tsinghua Workshop on Low-Carbon Development and Public Policy

| September 2018

The Belfer Center’s Environment and Natural Resources Program and the Center for Science, Technology, and Education Policy at Tsinghua University held the fifth annual Tsinghua-Harvard Workshop on Low-Carbon Development and Public Policy. This event brought together leading experts on climate and energy from academic, business, and government communities in both the United States and China. This year’s workshop focused on electricity systems and renewable energy penetration.

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.
