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.

Energy decisions reframed as justice and ethical concerns

| 6 May 2016

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.

Expert Views — and Disagreements — About the Potential of Energy Technology R&D

| June 2016

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.

China's Uranium Enrichment Complex

| October 23, 2015

New public information allows a fresh estimate of China's current and under-construction uranium enrichment capacity. This paper uses open source information and commercial satellite imagery to identify and offer estimates of the capacity of China's 10 operating enrichment facilities, located at 4 sites, using centrifuge technology most likely based on adapting Russian technology. The total currently operating civilian centrifuge enrichment capacity is estimated to be about 4.5 million separative work units/year (SWU/year), with additional capacity estimated to be about 2 million SWU/year under construction. Also China could have an enrichment capacity of around 0.6 million SWU/year for non-weapon military uses (i.e., naval fuel) or dual use. These estimates are much larger than previous public estimates of China's total enrichment capacity. Further expansion of enrichment capacity may be likely since China will require about 9 million SWU/year by 2020 to meet the enriched uranium fuel needs for its planned nuclear power reactor capacity of 58 gigawatts-electric (GWe) by 2020 under its policy of self-sufficiency in the supply of enrichment services.

How Much Bulk Energy Storage is Needed to Decarbonize Electricity?

| 2015

High cost and technical immaturity of bulk (multi-hour) electricity storage (BES) systems are often cited as major hurdles to increasing the penetration of intermittent renewables. The authors use a simple model to assess the economics of BES under carbon emissions constraints.

Plutonium Reprocessing, Breeder Reactors, and Decades of Debate: A Chinese Response

| July 1, 2015

Some observers believe that plutonium reprocessing is on the verge of an expansion, while others argue that the end of the practice is in sight. The risk of nuclear proliferation has always been the chief objection to reprocessing but proponents argue that today, with uranium enrichment technology more easily available, reprocessing no longer represents an efficient route toward nuclear weapons...

Beyond Carrots and Sticks: The Role of Status Ambitions and the NPT's “Double Standard” in Nuclear Arms Control Negotiations

| May 2015

This article examines why India walked away from the Comprehensive Test Ban Treaty (CTBT). After having spent years strongly advocating for a test ban accord, India changed course in the aftermath of the Nuclear Non-Proliferation Treaty's (NPT) indefinite extension in 1995, becoming the most outspoken opponent of the CTBT. This article argues that India's reversal cannot be explained by the conventional wisdom about (non-)compliance in nuclear arms control negotiations, which usually highlights the power of material interests. Since there was no development in the nuclear realm that might have compromised India's interests prior to its decision to change course, these theories fall short of explaining India's sudden opposition to the CTBT. The same holds true for the influence of norms. This article instead argues that perceived disrespect precipitated India's decision to abandon the treaty. India criticized the NPT as biased because it enforced non-proliferation without obligating the nuclear superpowers to disarm. Similarly, New Delhi believed the NPT's indefinite renewal made a mockery of a proud country's political claims.
