In this article, the authors review the state of the art of ocean energy in desalination. It explores different sources of energy from the ocean that include electricity generation, as well as mechanical force and thermal energy and salinity gradients that can also be directly harnessed for powering the desalination processes. They also examine recent advances in scaling up for commercial deployment and discuss relevant cost, environmental, and social concerns.

The introduction of new energy technologies may lead to public resistance and contestation. It is often argued that this phenomenon is caused by an inadequate inclusion of relevant public values in the design of technology. In this paper, the authors examine the applicability of the value sensitive design (VSD) approach.

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.

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.

Through structured interviews and a literature review, we assess which approaches to protection against insider thefts in the casino and pharmaceutical industries could be usefully applied to strengthen protections against insider theft in the nuclear industry, where insider thefts could have very high consequences.

Probabilistic estimates of the cost and performance of future nuclear energy systems under different scenarios of government research, development, and demonstration (RD&D) spending were obtained from 30 U.S. and 30 European nuclear technology experts. The majority expected that such RD&D would have only a modest effect on cost, but would improve performance in other areas, such as safety, waste management, and uranium resource utilization. The U.S. and E.U. experts were in relative agreement regarding how government RD&D funds should be allocated, placing particular focus on very high temperature reactors, sodium-cooled fast reactors, fuels and materials, and fuel cycle technologies.

By analyzing the institutions that have been created to stimulate energy technology innovation in the United States, the United Kingdom, and China—three countries with very different sizes, political systems and cultures, natural resources, and histories of involvement in the energy sector—this article highlights how variations in national objectives and industrial and political environments have translated into variations in policy.

In order to expand nuclear power energy in desalination and increase competitiveness in the global nuclear power market, many developed countries with strong nuclear technology have realized the importance of Small Modular Reactors (SMR) and initiated heavy research and development in SMR．The Advanced Small Pressurized Water Reactor (ASPWR) is characterized by great advantages, both in safety and economic mattters. It can be used in remote power grids and replace mid／small size fossil plants economically．This paper reviews the history and current status of SMR and ASPWR，and also discusses the design concepts, safety features and other advantages thereof.

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.

"...[W]hile the traditional form of balance of power between Iran and Iraq provided security for the Arab states of the Persian Gulf, it favored the interests of foreign actors, especially the United States. Proponents of such a view hold that following the overthrow of the Baathist regime in Iraq and the growth of Iran's role and influence in the region, the international community ought to establish a new kind of balance of power to restrain the Islamic Republic of Iran, and thereby preserve the security of the region. Following its failure to redefine the position of the new Iraq in terms of a new balance of power, the United States has itself tried to play such a role in the region. U.S. efforts to minimize Iran's role within the context of the new balance of power have consequently created another security dilemma in the Persian Gulf."
