Ocean Issues in Alaska: From Fisheries Management to Public Safety and Security

| Aug. 23, 2023

Alaska is an important region for the Department of Homeland Security (DHS), given the
Department’s statutory authority and responsibilities. This reality applies with particular force to the U.S. Coast Guard (USCG), with its jurisdiction over fisheries enforcement, drug interdiction, marine safety, oil spill response, search and rescue, and more. This policy brief provides an overview of the challenges facing the USCG in its domains of operation around Alaska—the Arctic Ocean, the North Pacific Ocean, the Bering Sea, the
Chukchi Sea, and the adjacent communities.

Carbon Capture, Utilization, and Storage: Carbon Dioxide Transport Costs and Network-Infrastructure Considerations for a Net-Zero United States

| July 20, 2023

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.

Progress on Carbon Capture, Utilization, and Storage Is Good News

| Mar. 28, 2023

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.

Bering Strait Navigation and Conservation in Times of Conflict

| November 2022

As climate change and economic activity in the region accelerate in the Bering Strait region, the United States and Russia have a common interest in mitigating these shared environmental risks. A November workshop hosted by Harvard Kennedy School’s Arctic Initiative, the Wilson Center’s Polar Institute, and the World Wildlife Fund (WWF) brought together seventeen experts to explore potential actions that the United States and Russia could pursue, jointly or independently, to protect the Bering Strait’s sensitive marine ecosystem and coastal communities.

Carbon Capture, Utilization, and Storage: Technologies and Costs in the U.S. Context

| January 2022

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.

Foundations for a Low-Carbon Energy System in China

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.

Mission Hydrogen: Accelerating the Transition to a Low Carbon Economy

To accelerate the global transition to a low-carbon economy, all energy systems must be actively decarbonized. While hydrogen has been a staple in the energy and chemical industries for decades, clean hydrogen – defined as hydrogen produced from water electrolysis with zero-carbon electricity – has captured increasing political and business momentum as a versatile and sustainable energy carrier in the future carbon-free energy puzzle.

The Arctic Needs Better Cross-sector Crisis-related Collaboration

| Aug. 06, 2020

Arctic Innovator Jenna Stark recommends closing the crisis-related collaboration gap in the polar region. Greater communication between emergency response specialists is needed both for the Arctic to weather the current coronavirus crisis and also to prepare for and mitigate future disasters, such as assuring food security for remote communities in the event of a wildlife disease outbreak.

Deescalation Wanted: How Trump Can Steer Clear of a War

| June 26, 2019

The United States and Iran have engaged in a constant raising of the stakes as a means of securing leverage ahead of possible nuclear negotiations. This is a classic bargaining pattern but in the current context, such an approach is particularly risky due to the potential for misperceptions. The complexities of domestic and regional dynamics are also a factor. In such a situation, absent clear understanding of the other’s motivations and tactics, raising the stakes—rather than securing leverage for effective negotiations—could steer the United States and Iran towards a path toward war.

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.
