A Process for Capturing CO2 from the Atmosphere

    Authors:
  • Geoffrey Holmes
  • David St. Angelo
  • Kenton Heidel
| 2018

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.

Trump and Putin Face an Urgent Arms Control Deadline in Helsinki

| July 12, 2018

As US-Russian relations continue to deteriorate, Presidents Trump and Putin appear eager to find common ground on arms control when they meet in Helsinki on Monday. The reason for their urgency is clear: The framework that has stabilized the US-Russian strategic balance since the fall of the Soviet Union is in danger of collapsing.

The Trump-Putin Summit’s Potential Nuclear Fallout

| July 10, 2018

The July 16 summit in Helsinki between Presidents Donald Trump and Vladimir Putin presents a unique opportunity to reverse the dangerous nuclear competition between the United States and Russia and should be welcomed, despite its inherent risks. The opportunity to stabilize U.S.-Russian nuclear relations by extending New START, a key nuclear treaty that is set to expire in 2021, is paramount and worth the issues that come with any meeting between Trump and Putin.

Preventing Black-Market Trade in Nuclear Technology

| June 2018

Every nuclear weapons program for decades has relied extensively on illicit imports of nuclear-related technologies. This book offers the most detailed public account of how states procure what they need to build nuclear weapons, what is currently being done to stop them, and how global efforts to prevent such trade could be strengthened. While illicit nuclear trade can never be stopped completely, effective steps to block illicit purchases of nuclear technology have sometimes succeeded in slowing nuclear weapons programs and increasing their costs, giving diplomacy more chance to work. Hence, this book argues, preventing illicit transfers wherever possible is a key element of an effective global non-proliferation strategy.

Simultaneous Pursuit of Discovery and Invention in the US Department of Energy

There is a sharp boundary between basic and applied research in the organizational structure of the US Department of Energy (DOE). In this work, the authors consider a branch of DOE that was designed to operate across this boundary: the Advanced Research Projects Agency — Energy (ARPA-E). They hypothesize that much of energy research cannot be neatly categorized as basic or applied and is more productive outside of the confines of the basic/applied dichotomy; ARPA-E provides an opportunity to test that hypothesis.
