The authors describe a process for capturing CO2 from the atmosphere in an industrial plant. The design captures ∼1 Mt-CO2/year in a continuous process using an aqueous KOH sorbent coupled to a calcium caustic recovery loop. They describe the design rationale, summarize performance of the major unit operations, and provide a capital cost breakdown developed with an independent consulting engineering firm. They report results from a pilot plant that provides data on performance of the major unit operations.

In a new book, the Harvard Kennedy School’s Graham Allison looks at how the power struggle between Athens and Sparta in classical Greece offers important insights into the looming complexities as China’s meteoric rise threatens to displace the U.S. as the dominant world power.

Indian Prime Minister Narendra Modi traveled to Washington last week, making his fourth trip to the United States since taking office just two years ago. India and South Asia Program Fellow, Ronak Desai examines the strategic approach to India's relations with the United States.

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.

In order to make R&D funding decisions to meet particular goals, such as mitigating climate change or improving energy security, or to estimate the social returns to R&D, policy makers need to combine the information provided in this study on cost reduction potentials with an analysis of the macroeconomic implications of these technological changes. The authors conclude with recommendations for future directions on energy expert elicitations.

Professor Meghan O'Sullivan was interviewed on November 15th, 2015 for a Wall Street Journal special section on energy, discussing the rapid transformation of the American energy sector in light of low fuel prices, new climate policies and other factors.
