The Nuclear Balance Is What States Make of It

    Author:
  • David C. Logan
| Spring 2022

Recent quantitative scholarship uses warhead counts to examine whether nuclear superiority offers political or military benefits beyond having a secure second-strike capability. These analyses overlook other elements of a state’s nuclear capability such as state perceptions and beliefs.

| Winter 2020/21

South Korea’s conventional counterforce and countervalue strategy is a manifestation of its uncertainties over the reliability of the U.S. alliance. This strategy has significant implications for strategic stability and the potential for denuclearization on the Korean Peninsula.

Successful Clean Energy Technology Transitions in Emerging Economies: Learning from India, China, and Brazil

| 2020

Technological innovation and widespread deployment of clean-energy technologies in emerging economies are critical for a global clean energy transition. Success or failure in this endeavour will have long-term energy and carbon consequences. A fundamental question exists about whether, and how, emerging economies can accelerate clean-energy transitions, given the unprecedented scales of their impending socio-economic and infrastructure transitions, and often-underdeveloped technological innovation capabilities and supporting finances.

Patenting and Business Outcomes for Cleantech Startups Funded by the Advanced Research Projects Agency-Energy

The authors examine the impact of the US Advanced Research Projects Agency-Energy (ARPA-E) on two outcomes for startup companies: innovation (measured by patenting activity) and business success (measured by venture capital funding raised, survival, and acquisition or initial public offering).

Illuminating Homes with LEDs in India: Rapid Market Creation Towards Low-carbon Technology Transition in a Developing Country

| August 2020

This paper examines a recent, rapid, and ongoing transition of India's lighting market to light emitting diode (LED) technology, from a negligible market share to LEDs becoming the dominant lighting products within five years, despite the country's otherwise limited visibility in the global solid-state lighting industry.

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.

Governments as Partners: The Role of Alliances in U.S. Cleantech Startup Innovation

Accelerating innovation in clean energy technologies is a policy priority for governments around the world aiming to mitigate climate change and to provide affordable energy. Most research has focused on the role of governments financing R&D and steering market demand, but there is a more limited understanding of the role of direct government interactions with startups across all sectors. The authors  propose and evaluate the value-creation mechanisms of network resources from different types of partners for startups, highlighting the unique resources of government partners for cleantech startups.

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.

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.
