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.

Governments as Partners: The Role of Alliances in U.S. Cleantech Startup Innovation

Accelerating innovation in clean energy technologies is a policy priority for governments around the world aiming to mitigate climate change and to provide affordable energy. Most research has focused on the role of governments financing R&D and steering market demand, but there is a more limited understanding of the role of direct government interactions with startups across all sectors. The authors  propose and evaluate the value-creation mechanisms of network resources from different types of partners for startups, highlighting the unique resources of government partners for cleantech startups.

Economics of the Environment: Selected Readings

| 2019

Now in its seventh edition, Economics of the Environment serves as a valuable supplement to environmental economics text books and as a stand-alone reference book of key, up-to-date readings from the field. Edited by Robert N. Stavins, the book covers the core areas of environmental economics courses as taught around the world; and the included authors are the top scholars in the field. Overall, more than half of the chapters are new to this edition while the rest have remained seminal works.

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.

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

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.

Recycling-Based Reduction of Energy Consumption and Carbon Emission of China's Electric Vehicles: Overview and Policy Analysis

Electric vehicles maintain the fastest development in China and undertake the responsibility of optimizing energy consumption and carbon emission in the transportation field. However, from the entire life cycle point of view, although electric vehicles have a certain degree of energy consumption and carbon emission reduction in the use phase, they cause extra energy consumption and carbon emission in the manufacturing phase, which weakens the due environmental benefits to some extent. The recycling of electric vehicles can effectively address the issue and indirectly reduce the energy consumption and carbon emission in the manufacturing phase. China is setting up the recycling system and strengthening regulation force to achieve proper energy consumption and carbon emission reduction benefits of electric vehicles.

| May 15, 2018

Electrification with decarbonized electricity is a central strategy for carbon mitigation. End-use electrification can also reduce air pollutant emissions from the demand sectors, which brings public health co-benefits. In this article, the authors focus on electrification strategies for China, a country committed to both reducing air pollution and peaking carbon emissions before 2030. Considering both coal-intensive and decarbonized power system scenarios for 2030, they assess the air quality, health, and climate co-benefits of various end-use electrification scenarios for the vehicle and residential sectors relative to a non-electrified coal-intensive business-as-usual scenario.

Why is China's Wind Power Generation Not Living Up to its Potential?

Following a decade of unprecedented investment, China now has the world's largest installed base of wind power capacity. Yet, despite siting most wind farms in the wind-rich Northern and Western provinces, electricity generation from Chinese wind farms has not reached the performance benchmarks of the United States and many other advanced economies. This has resulted in lower environmental, economic, and health benefits than anticipated. The authors develop a framework to explain the performance of the Chinese and US wind sectors, accounting for a comprehensive set of driving factors.

Towards Sustainability in Water-energy Nexus: Ocean Energy for Seawater Desalination

In this article, the authors review the state of the art of ocean energy in desalination. It explores different sources of energy from the ocean that include electricity generation, as well as mechanical force and thermal energy and salinity gradients that can also be directly harnessed for powering the desalination processes. They also examine recent advances in scaling up for commercial deployment and discuss relevant cost, environmental, and social concerns.
