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.

Stochastic Cost-benefit Analysis of Urban Waste-to-Energy Systems

Municipal solid waste generation is a rapidly increasing challenge that is leading to severe pollution and environmental degradation in many urban areas of developing countries. This study presents the Waste to Energy Recovery Assessment (WERA) framework, a new quantitative decision support model for initial evaluation and alternative comparisons of different thermochemical treatments of municipal wastes. The framework is used to study waste-to-energy (WtE) systems for Abu Dhabi, Riyadh, Tokyo, and New York. The results show that WtE systems can fulfill only 1.4–3.6% of 2014 electricity demand in the analyzed cases.

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

    Author:

| 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.

With the rapid growth of electric vehicles in China, their benefits should be scientifically identified to support the industry development. Although the life cycle benefits of electric vehicles have been analyzed worldwide, the recycling phase has not been fully studied yet, especially in China. Therefore, this study focuses on the economic and environmental benefits of electric vehicle recycling in China. Based on the technology adopted by leading enterprises, the gross income and reduction of energy consumption and greenhouse gas emissions are calculated to reveal the benefits.

As the single largest greenhouse gas emitter in the world and the source of almost 30 percent of the CO2 released into our atmosphere, China faces an enormous challenge in reaching its goal of zero or negative emissions—known as deep decarbonization.

Henry Lee, Director of the Environment and Natural Resources Program (ENRP), and Dan Schrag, Co-Director of the Science, Technology, and Public Policy Program, head a team of researchers from the U.S. and China who have been examining China’s work in achieving deep decarbonization in the People’s Republic. The team plans to publish its findings in a book to be released in 2019.

Arctic Initiative Takes Innovation and Expertise to Reykjavík

| Fall/Winter 2018-2019

Twenty-four Harvard Kennedy School students recently returned from the Arctic Circle Assembly in Reykjavík—the world’s largest annual gathering on Arctic issues—where each presented her or his innovative and interdisciplinary solution to an Arctic challenge. These “Arctic Innovators” are part of Harvard Kennedy School’s Arctic Initiative, which is co-led at the Belfer Center by John P. Holdren, Henry Lee, and Halla Logadóttir. Focused on policy responses to the challenges posed by rapid climate change in the Arctic, the Initiative has recently secured new outside funding totaling $3 million to cover programs over the next three years.

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.

China needs to manage its coal-dominated power system to curb carbon emissions, as well as to address local environmental priorities such as air pollution and water stress. In this article, the authors examine three province-level scenarios for 2030 that represent various electricity demand and low-carbon infrastructure development pathways.
