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.

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.

Both energy production and consumption can simultaneously affect regional air quality, local water stress and the global climate. Identifying the air quality–carbon–water interactions due to both energy sources and end-uses is important for capturing potential co-benefits while avoiding unintended consequences when designing sustainable energy transition pathways. The authors examine the air quality–carbon–water interdependencies of China's six major natural gas sources and three end-use gas-for-coal substitution strategies in 2020.

A Process for Capturing CO2 from the Atmosphere

    Authors:
  • Geoffrey Holmes
  • David St. Angelo

| 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.

Changing Carbon Content of Chinese Coal and Implications for Emissions of CO2

| September 2018

The changing carbon content of coal consumed in China between 2002 and 2012 is quantified using information from the power sector. The carbon content decreased by 7.7% over this interval, the decrease particularly pronounced between 2007 and 2009. Inferences with respect to the changing carbon content of coal and the oxidation rate for its consumption, combined with the recent information on coal use in China, are employed to evaluate the trend in emissions of CO2. Emissions are estimated to have increased by 158% between 2002 and 2012, from 3.9 Gt y-1 to 9.2 Gt y-1.

Climate, Air Quality and Human Health Benefits of Various Solar Photovoltaic Deployment Scenarios in China in 2030

    Authors:

Solar photovoltaic (PV) electricity generation can greatly reduce both air pollutant and greenhouse gas emissions compared to fossil fuel electricity generation. The Chinese government plans to greatly scale up solar PV installation between now and 2030. However, different PV development pathways will influence the range of air quality and climate benefits. Benefits depend on how much electricity generated from PV is integrated into power grids and the type of power plant displaced. Using a coal-intensive power sector projection as the base case, the authors estimate the climate, air quality, and related human health benefits of various 2030 PV deployment scenarios.

Sovereign Wealth Funds in Small Open Economies

| Apr. 24, 2018

The small open economies of the Gulf and Southeast Asia are pioneers in the establishment of

Sovereign Wealth Funds (SWFs). The SWFs of countries like Qatar and Singapore are among the

world’s largest in terms of total asset size relative to Gross Domestic Product. This article looks

at the different compulsions behind the setting up of SWFs by small open economies.

The Case for Economic Development Through Sovereign Investment: A Paradox of Scarcity?

| Apr. 14, 2018

Sovereign wealth funds (SWFs) have traditionally been created to recycle excess reserves from natural resource or non‐commodity revenues. However, in recent years funds are being established under conditions of capital scarcity with objectives to contribute domestic economic development, often through the buildout of national infrastructure programs. Such trends in new fund creation represent a fundamental shift in the sovereign wealth fund paradigm and raise serious questions about how these entities are to be capitalized and also the implications of capitalization models on their sustainability. This study examines the recent evolution of SWF models focused on economic development. Its analytic focus is drawn, in particular, to countries that are neither endowed with oil wealth, nor otherwise enjoy export surpluses to be used to capitalize a development‐oriented SWF. While this study is relevant to and expands the scope of the broad literature on SWFs, its specific contribution is as a focused analysis of how SWF funding sources impact achieving long‐term financial and socio‐economic development objectives.
