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.

Saudi Arabia’s Moment in the Sun

| May 07, 2019

As part of a high profile tour of China in February, Saudi Arabia’s Crown Prince Mohammed Bin Salman (MBS) has overseen a range of multi-billion dollar pledges and MOUs with Beijing. This partly reflects Riyadh’s desire to diversify sources for investments and technology following the mass withdrawal of major Western business leaders from the Future Investment Initiative in October 2018, after the murder of Saudi Journalist Jamal Khashoggi in the Saudi Embassy in Istanbul. Yet cooperation with China on renewable energy, if successful, would realize a significant first step towards Saudi Arabia’s lofty ambitions for solar and wind power.

Energy Abundance and the Environment: An Interview with Meghan L. O’Sullivan, Part 2

| Apr. 03, 2019

The subtitle tells the story. In the early 2000s, many pundits and politicians talked up “peak oil”, “energy scarcity,” and all that. In a geological heartbeat later—about a decade—the world had entered an era of “energy abundance,” largely due to innovations that allowed producers to crack into shale formations to release massive new sources of oil and gas. The United States has gone furthest and fastest in fracking and is setting records for oil and gas production. For the US, says O’Sullivan, this has been an economic, strategic, and environmental game-changer. For the rest of the world, the effects are more differentiated but hardly less profound.

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.

Uncovering the Domestic Factor in the Sino-Russian Energy Partnership

| Oct. 15, 2018

The article outlines the role of national narratives in driving both Russia and China’s energy foreign policy and goes on to argue that the Sino-Russian gas breakthrough in 2014 was due to the peculiar way in which domestic factors paired with international circumstances to produce the outcome at that particular moment.

The Silk Road between a Rock and a Hard Place: Russian and Chinese Competition for Central Asia's Energy

| Oct. 01, 2018

China’s displacement of Russian economic influence in Central Asia is generating great interest in Western academic and policy circles, but this research has, as yet, yielded few analytical nuances. This article attempts to shed light on the under-researched question of what explains Central Asian governments’ failure to more effectively capitalize on the growing Central Asian rivalry between Russia, China, the United States, Turkey, Iran, South Korea, Japan, and other regional powers that, since the early 1990s, has been overwhelmingly directed towards strategic energy considerations and hydrocarbon interests.

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.
