Ishimoto, Yuki; et al. (2017): Putting Costs of Direct Air Capture in Context

Ishimoto, Yuki; Sugiyama, Masahiro; Kato, Etsushi; Moriyama, Ryo; Tsuzuki, Kazuhiro; Kurosawa, Atsushi (2017): Putting Costs of Direct Air Capture in Context (FCEA Working Paper Series, 002).

“This working paper provides an overview of various estimates and claims on direct air capture (DAC) of carbon dioxide, and places them in a broader context of global climate policy. Unlike other techniques of climate engineering, DAC has received significant attention from startups since its main issue is deemed to be the direct implementation cost (not side effects or social concerns), which could be significantly reduced with successful innovation.”

“These two kinds of technologies generally raise different sets of technical, ethical, social, and legal concerns, leading to frequent calls to treat them separately. Since many of the reports being summarized here address both kinds of CE, this report will do so, too.”

Energy Post: The geo-engineering taboo

“A new book by David Hone, Chief Climate Change Adviser at Shell, takes the reader on a journey through the transition in the energy system that must be undertaken to address the climate change issue. The book, Putting the Genie Back: Solving the Climate and Energy Dilemma, deals with a wide range of topics, including carbon pricing, electric cars and solar power, and even ventures into areas such as the somewhat taboo subject of geo-engineering. What follows is an excerpt from the book where Hone discusses the geo-engineering solution.”

Wood, Robert; et al. (2017): Could geoengineering research help answer one of the biggest questions in climate science?

Wood, Robert; Ackerman, Thomas; Rasch, Philip; Wanser, Kelly (2017): Could geoengineering research help answer one of the biggest questions in climate science? In: Earth’s Future. DOI: 10.1002/2017EF000601.

“Observational studies show influences of aerosol on clouds, but correlations between aerosol and clouds are insufficient to constrain aerosol forcing because of the difficulty in separating aerosol and meteorological impacts. In this commentary, we argue that this current impasse may be overcome with the development of approaches to conduct control experiments whereby aerosol particle perturbations can be introduced into patches of marine low clouds in a systematic manner. Such cloud perturbation experiments constitute a fresh approach to climate science and would provide unprecedented data to untangle the effects of aerosol particles on cloud microphysics and the resulting reflection of solar radiation by clouds.”
