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.

A History of the Energy We Have Consumed

| June 18, 2018

Early in Richard Rhodes’s new book, “Energy: A Human History,” we hear of a prominent citizen using colorful language to lament the state of his polluted city and urge his government to shut down industry or move it elsewhere: “If there be a resemblance of hell upon earth, it is in this volcano [on] a foggy day.” Though this could easily apply to modern-day Beijing, the speaker here is John Evelyn, a wealthy horticulturalist and one of the founders of the scientific Royal Society of London — and he’s complaining about London in 1659.

The AI Advantage of Nations in the Fourth Industrial Revolution

| Apr. 17, 2018

Like revolutions in the past the on-going AI revolution will produce winners and losers. The first industrial revolution in the 18th century changed the world of production and paved the way for Britain’s global leadership. Similarly, the current digital revolution is redefining the service sector and China’s role in the world.

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.

Obama's Second-Term Energy Policy Is Working

| August 19, 2014

"President Obama has put energy and the environment at the top of his second-term agenda. The focus has been on climate change, and on exploiting the unexpected plenty of North American oil, gas and energy technology. The administration's progress has been notable...," writes John Deutch.

"The president's highest priority is to reduce the carbon-dioxide emissions of existing electricity generating power plants....The projected CO2 reductions—about 30% below 2005 levels by 2030—are reasonable and shouldn't significantly increase industry or consumer costs."

China's Coal Addiction a Threat to Its Energy Security

| May 14, 2014

"...[U]ntil now, Beijing's response to unmet energy demand has focused primarily on securing resources overseas, and building infrastructure for imports. China now generates more electricity from imported coal than from nuclear, wind and solar combined. Without a strong, coordinated policy shift, the country will depend on fuel imports for most of its energy consumption by the time it becomes a developed country."
