Science, Technology, and Public Policy

This brief examines the national challenges related to deploying and scaling infrastructure to transport CO₂ from capture sites to storage or utilization sites at a scale consistent with achieving net-zero by 2050.

Daniel Schrag and Henry Lee discuss the policies China could enact in the near-term to ease its transition to a low-carbon economy, the subject of their book Foundations for a Low-Carbon Energy System in China (Cambridge University Press, 2021). 

If the world is serious about addressing climate change, we should welcome forward momentum on this critical technology. Getting on track for net zero emissions by 2050 will require swiftly and massively ramping up carbon capture deployment.

The energy transition has made deep-sea mining for critical minerals cost-competitive for the first time, and Chinese companies are champing at the bit to start mining at a commercial scale. The United States and its partners, by contrast, have been caught on the back foot when it comes to China’s stranglehold on the critical mineral supply chain. With the geopolitical rivalry between China and the United States intensifying, many Western observers say the United States can’t afford to lose the scramble for the seabed. 

Institutional reforms are key to China tackling climate change. More are needed to secure a low-carbon future, write Henry Lee and Daniel Schrag.

Carbon capture, utilization, and storage (CCUS) is very likely to be a key technology for achieving the Biden administration's goal of net-zero greenhouse gas emissions by 2050. But absent regulation requiring its use, CCUS needs to become more economical in order for deployment in the United States to expand significantly.

How can China make good on its pledge to reach carbon neutrality by 2060? In Foundations for a Low-Carbon Energy System in China, a team of experts from China and the United States explains how China's near-term climate and energy policies can affect long-term decarbonization pathways beyond 2030, building the foundations for a smoother and less costly national energy transformation.

This article examines both the premise and prescription of the argument to integrate renewable electricity in developing countries through elements of the standard model (such as a wholesale spot market, or an independent system operator for dispatch). This is done by highlighting the differences between power sector reform experiences in the developing and developed worlds, and the causal mechanisms underlying these differences.

Renewable hydrogen offers significant advantages for China. It can help Beijing meet its climate and pollution goals—at a time when coal continues to dominate—while avoiding increased reliance on imported fuels. As a readily dispatchable means of storing energy, hydrogen can help to address intermittency and curtailment issues as renewable energy increases its share of China’s energy mix. As a sustainable mobility energy carrier, it can power fuel-cell electric vehicles or be the base for synthetic fuels. Finally, renewable hydrogen can open new avenues for developing clean technology manufactured goods for both internal and export markets.

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.
