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.

For more than a decade there has been talk of a global “nuclear renaissance,” and until recently Vietnam looked to be part of it, making plans to build nuclear infrastructure and taking the necessary steps to become a member of the international nuclear community. Then, last month, after a year or more of troubling signs, the government officially suspended its nuclear development plans.

New technology brings great benefits, but it can also create new and significant risks. When evaluating those risks in policymaking, there is a tendency to focus on social acceptance. By solely focusing on social acceptance, important ethical aspects of technological risk could be overlooked, particularly when evaluating technologies with transnational and intergenerational risks. The author examines the case of multinational nuclear waste repositories.

In the late 2000s, energy forecasts began to use the term “nuclear renaissance” to refer to the fast-growing nuclear power program of China, and to the emergence of the so-called “nuclear aspirants” embarking on their first nuclear power projects. Many among these newcomers are members of the Association of Southeast Asian Nations (ASEAN). For this reason, nuclear suppliers like the United States, Russia, Japan, and South Korea have been particularly active in signing cooperation agreements with ASEAN nations or supporting these countries to explore the feasibility of nuclear energy.

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.

Based on multi-archival research, this article explores the significance of Franco-Indian nuclear relations against the backdrop of Anglo-American endeavours to censor information related to atomic energy and to secure control of strategic minerals during the early Cold War.

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.

China will triple the number of nuclear power plants it has in operation by 2020 according to official plans, and the country’s nuclear fleet will increase 20-fold by 2050 under some not-yet-approved proposals. But how and where will China get the uranium to fuel them all? Will China need to resort to breeder reactors and reprocessing, with all the proliferation problems they incur? Or is there another way? In this journal article for the Bulletin of the Atomic Scientists, Hui Zhang suggests that between China’s domestic uranium mining, uranium purchased on the international market, and uranium mined by Chinese-owned companies overseas, China could meet even the most ambitious target, thus avoiding the troublesome and dangerous path of reprocessing.

"A mere three-and-a-half years after the catastrophic nuclear events at Fukushima Daiichi in Japan, it is still too early to draw conclusions about how Fukushima has affected global nuclear energy policy. The first signs of future policy do, however, seem to indicate that there will be no major changes in nuclear power forecasts in the immediate future."
