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.

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.

Technology Innovation and Energy

Energy technology innovation is the key to driving the technological changes that are necessary to meet the challenge of mitigating energy-related greenhouse gas emissions to avoid 'dangerous climate change.' Success in innovation requires the enhancement of public investment in the innovation process, the creation of markets for low-carbon technologies through stronger climate policies, and a continued focus on energy access and equity.

What Next on Climate?

| Summer 2011

The effort to address climate change stumbled with the failure to pass cap-and-trade. What should happen now? Five experts, including the Harvard Project's Joe Aldy, discuss the future of U.S. climate and energy policy.

Preparing to Ramp up Large-scale CCS Demonstrations: An Engineering-economic Assessment of CO2 Pipeline Transportation in China

| July 2011

An integrated carbon dioxide (CO2) capture and storage (CCS) system requires safe and cost-efficient solutions for transportation of the CO2 from the capturing facility to the location of storage. While growing efforts in China are underway to understand CO2 capture and storage, comparatively less attention has been paid to CO2 transportation issues. Also, to the best of our knowledge, there are no publicly available China-specific cost models for CO2 pipeline transportation that have been published in peer-reviewed journals. This paper has been developed to determine a first-order estimate of China's cost of onshore CO2 pipeline transportation.

Advancing Carbon Capture and Sequestration in China: A Global Learning Laboratory

| 2010/2011

China's dependency on coal fuels the country's phenomenal economic growth but at a major cost to the country's air and water quality, ultimately threatening human health and the country's continued economic growth. The Chinese government's efforts to put China onto a cleaner, low carbon development path have been substantial; however China's pollution and greenhouse gas emissions continue to grow. In an attempt to develop its own advanced coal generation technologies to improve the country's air quality and energy efficiency, the Chinese government is investing heavily in gasification and other technologies that can be employed in carbon capture and sequestration (CCS) applications. This investment has turned China into a global laboratory for CCS pilot projects, attracting foreign governments, multilateral institutions, nongovernmental organizations, and business partners.
