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.

Energy decisions reframed as justice and ethical concerns

| 6 May 2016

Many energy consumers, and even analysts and policymakers, confront and frame energy and climate risks in a moral vacuum, rarely incorporating broader social justice concerns. Here, to remedy this gap, we investigate how concepts from justice and ethics can inform energy decision-making by reframing five energy problems — nuclear waste, involuntary resettlement, energy pollution, energy poverty and climate change — as pressing justice concerns.

Viewpoint Iran: The Past and Present of the U.S.-Iran Standoff

| October 2013

"While Americans understand relations with Iran in terms of its nuclear program and incendiary anti-Israel homilies, Iranians see the relationship as part of a long and troubling history of foreign intervention and exploitation that reaches back into the nineteenth century. Iranian leaders argue that if interactions between Iran and the United States are to improve, this history will have to be addressed and rectified."

Preparing to Ramp up Large-scale CCS Demonstrations: An Engineering-economic Assessment of CO2 Pipeline Transportation in China

| July 2011

An integrated carbon dioxide (CO2) capture and storage (CCS) system requires safe and cost-efficient solutions for transportation of the CO2 from the capturing facility to the location of storage. While growing efforts in China are underway to understand CO2 capture and storage, comparatively less attention has been paid to CO2 transportation issues. Also, to the best of our knowledge, there are no publicly available China-specific cost models for CO2 pipeline transportation that have been published in peer-reviewed journals. This paper has been developed to determine a first-order estimate of China's cost of onshore CO2 pipeline transportation.

Advancing Carbon Capture and Sequestration in China: A Global Learning Laboratory

| 2010/2011

China's dependency on coal fuels the country's phenomenal economic growth but at a major cost to the country's air and water quality, ultimately threatening human health and the country's continued economic growth. The Chinese government's efforts to put China onto a cleaner, low carbon development path have been substantial; however China's pollution and greenhouse gas emissions continue to grow. In an attempt to develop its own advanced coal generation technologies to improve the country's air quality and energy efficiency, the Chinese government is investing heavily in gasification and other technologies that can be employed in carbon capture and sequestration (CCS) applications. This investment has turned China into a global laboratory for CCS pilot projects, attracting foreign governments, multilateral institutions, nongovernmental organizations, and business partners.

Catalyzing Strategic Transformation to a Low-carbon Economy: A CCS Roadmap for China

| January 2010

China now faces the three hard truths of thirsting for more oil, relying heavily on coal, and ranking first in global carbon dioxide (CO2) emissions. Given these truths, two key questions must be addressed to develop a low-carbon economy: how to use coal in a carbon-constrained future? How to increase domestic oil supply to enhance energy security? Carbon Capture and Storage (CCS) may be a technological solution that can deal with today's energy and environmental needs while enabling China to move closer to a low-carbon energy future. This paper has been developed to propose a possible CCS roadmap for China.

Driving Carbon Capture and Storage Forward in China

| February 2009

Carbon Capture and Storage (CCS), as an option in the portfolio of mitigation actions to combat climate change, is expected to have far-reaching implications for China. This paper (1) explores the strategic significance of CCS for China by making an extreme scenario analysis of Chinese power sector in 2030; (2) provides an overview of the recent CCS activities in China; and (3) identifies the major challenges with respect to CCS development in China and put forwards immediate strategies.

Sustainable Development of the Indian Coal Sector

| In Press

Increased availability of energy, especially electricity, is important for India to help advance economic and human development. Coal, which currently accounts for more than 50% of total primary commercial energy supply in the country and for about 70% of total electricity generation, is likely to remain a key energy source for India for at least the next 30–40 years. Thus, sustainable development of the Indian coal sector is necessary to ensure the ability to sustain the increased production of coal in the country and to do so in an environmentally and socially sustainable manner.

Carbon Mitigation in the Indian Coal-Power Sector: Options and Recommendations

| February 2009

Given coal's large contribution to India's emissions, it is important to explore options for reducing emissions from the Indian coal power sector. Even as India awaits stronger action by industrialized countries, several no-regrets options can still be instituted to position the Indian coal-power sector appropriately for an eventual deeper carbon mitigation strategy: (a) improve efficiency of generation, transmission and distribution, and end-use systems; (b) aggressively deploy higher-efficiency coal combustion technologies; (c) develop a strategic plan for technology innovation; (d) improve environmental regulations to keep open economic carbon capture options; and (e) invest in detailed geological assessment of carbon storage sites.

Technical, Environmental, and Economic Assessment of Deploying Advanced Coal Power Technologies in the Chinese Context

| July 2008

The authors evaluate the differences in technical performance, environmental impact, and costs for capital and electricity for a variety of advanced coal power technologies based on the technological and economic levels in 2006 in China. This study investigates especially the economic gaps between Integrated Gasification Combined Cycle - the technology most able to capture CO2 at a relatively low cost - and other advanced coal power technologies.
