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.

Potential Arbitrage Revenue of Energy Storage Systems in PJM

| 2017

The volatility of electricity prices is attracting interest in the opportunity of providing net revenue by energy arbitrage. The authors analyzed the potential revenue of a generic Energy Storage System (ESS) in 7395 different locations within the electricity markets of Pennsylvania-New Jersey-Maryland interconnection (PJM), the largest U.S. regional transmission organization, using hourly locational marginal prices over the seven-year period 2008–2014.

A Case Study of a World-Class Research Project Accomplished in China: Lessons for China's Science Policy

| February 2017

It has long been a great Chinese ambition to have a high impact toplevel scientific research conducted in domestic China. In this paper, we provide a case study of the recent discovery of the Quantum Anomalous Hall Effect by the group led by Prof. Qikun Xue at Tsinghua University. We analyze the entire experimental discovery process, explore the research culture developed in this condensed matter and materials physics research group, examine China's funding environment and investigate the functioning of this multi-group collaboration. Lessons from this case study will shed lights on how to foster high impact world-class research institutions in China.

A Case Study of a World-class Research Project Accomplished in China: Discovery of the Quantum Anomalous Hall Effect

The authors analyze the Quantum Anomalous Hall Effect (QAHE) discovery process, with the focus on the emerging research culture in post-Cultural-Revolution China, explore how an effective research leader can mobilize all relevant resources toward one common goal, and discuss how reform in China's S&T administration and funding may facilitate similar scientific breakthrough and innovation.

Thermodynamic Disequilibrium of the Atmosphere in the Context of Global Warming

| December 2015

The atmosphere is an example of a non-equilibrium system. This study explores the relationship among temperature, energy and entropy of the atmosphere, introducing two variables that serve to quantify the thermodynamic disequilibrium of the atmosphere.

A 32-year Perspective on the Origin of Wind Energy in a Warming Climate

| May 2015

Based on assimilated meteorological data for the period January 1979 to December 2010, the authors investigate the origin of wind energy from both mechanical and thermodynamic perspectives, with special focus on the spatial distribution of sources, historical long-term variations, and the efficiency for kinetic energy production.
