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.

Twitter Diplomacy: Preventing Twitter Wars from Escalating into Real Wars

| May 20, 2019

Just two weeks ago, a tweet cost the global stock markets roughly $1.36 trillion (or Australia’s annual GDP). With 280 characters on Twitter, the U.S. President Donald Trump threatened to raise tariffs on select Chinese imports, instilling lower market confidence, triggering significant volatility, and exacerbating existing political uncertainties. To explore what is really at stake in Twitter diplomacy, it is important to explore why Twitter diplomacy matters, why world leaders use it, what it means for diplomatic relations, and how governments can manage the associated risks.

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.

A History of the Energy We Have Consumed

| June 18, 2018

Early in Richard Rhodes’s new book, “Energy: A Human History,” we hear of a prominent citizen using colorful language to lament the state of his polluted city and urge his government to shut down industry or move it elsewhere: “If there be a resemblance of hell upon earth, it is in this volcano [on] a foggy day.” Though this could easily apply to modern-day Beijing, the speaker here is John Evelyn, a wealthy horticulturalist and one of the founders of the scientific Royal Society of London — and he’s complaining about London in 1659.
