The escalating level of atmospheric carbon dioxide is one of the most pressing environmental concerns of our age. Carbon capture and storage (CCS) from large point sources such as power plants is one option for reducing anthropogenic CO(2) emissions; however, currently the capture alone will increase the energy requirements of a plant by 25-40%. This Review highlights the challenges for capture technologies which have the greatest likelihood of reducing CO(2) emissions to the atmosphere, namely postcombustion (predominantly CO(2)/N(2) separation), precombustion (CO(2)/H(2)) capture, and natural gas sweetening (CO(2)/CH(4)). The key factor which underlies significant advancements lies in improved materials that perform the separations. In this regard, the most recent developments and emerging concepts in CO(2) separations by solvent absorption, chemical and physical adsorption, and membranes, amongst others, will be discussed, with particular attention on progress in the burgeoning field of metal-organic frameworks.

Carbon Dioxide Capture: Prospects for New Materials

The talk with present the key results of the IPCC Working Group III 5th assessment report. Concluding four years of intense scientific collaboration by hundreds of authors from around the world, the report responds to the request of the world's governments for a comprehensive, objective and policy neutral assessment of the current scientific knowledge on mitigating climate change. The report has been extensively reviewed by experts and governments to ensure quality and comprehensiveness.

Publisher Summary The U.S. Department of Energy (DOE), New Energy and Industrial Technology Development Organization of Japan (NEDO), and Norwegian Research Council (NRC) entered into a Project Agreement for International Collaboration on CO2 Ocean Sequestration in Kyoto on December 4, 1997. By signing the agreement during the Third Conference of Parties to the United Nations Framework Convention on Climate Change (COP-3), the groups demonstrated their commitment to mitigating climate change, but also opened themselves to international scrutiny. DOE, NEDO and NRC agreed to an initial field experiment on ocean carbon sequestration via direct injection. These original ‘sponsors” were later joined by the Commonwealth Scientific and Industrial Research Organization (CSIRO) of Australia, Natural Resources Canada (NRCan) and the Swiss/Swedish firm Asea Brown Bovery (ABB). The sponsors created a Steering Committee (SC) to manage the direction of the project. In addition, a Technical Committee (TC) consisting of the participating research institutions was formed to guide scientific aspects. The purpose of the initial experiment was to secure reliable field data that could be applied to understand how the chemical environment of the deep ocean is perturbed by direct injection. The data would be used to develop models to accurately predict chemical changes for a range of injection scenarios. This would be the first critical step in understanding the environmental impacts of the direct injection of CO2 into the ocean.

Ocean Carbon Sequestration: A Case Study in Public and Institutional Perceptions

Many governments have begun to adopt aggressive targets for electric vehicles. However, studies of the drivers of electric vehicle (EV) adoption are scarce. Social media interactions can provide a new data-driven vantage point to explore such drivers. This study uses data from 36,000 public posts on Facebook to investigate intersectionality in EV-communication as per the Political, Economic, Social, Technological, Legal and Environmental (PESTLE) categories. A computational social science methodology was adopted using a mixed-method application of social network analysis and machine learning-based topic modelling through Latent Dirichlet Allocation algorithm on a 600,000-text corpus extracted from the Facebook posts. Results showed that political, economic, and legal posts had dense clusters around the technology policy of EV, the institutional discourse of electrification of the federal vehicle fleet, and tax and credit framework politics. The environmental and social dimensions had a higher discourse for social justice, clean air, and better health and well-being. A market shift towards EV as a service industry was observed in the technology and economics-related posts. These findings can help policymakers, and planners design contextualised energy policy for influencing EV adoption in the U.S. and other countries.
