Comparing with other renewable energy the nuclear power chain has very low greenhouse gas emission, so it will play more important role in China's low-carbon economy. The paper also discussed the necessity of nuclear power development to achieve emission reduction, energy structure adjustment, nuclear power safety,environmental protection, enhancement of nuclear power technology, nuclear waste treatment, and disposal, as well as nuclear power plant decommissioning. Based on the safety record and situation of the existing power plants in China, the current status of the development of world nuclear power technology, and the features of the independently designed advanced power plants in China, this paper aims to demonstrate the safety of nuclear power. A nuclear power plant will not cause harm either to the environment and nor to the public according to the real data of radioactivity release, which are obtained from an operational nuclear plant. The development of nuclear power technology can enhance the safety of nuclear power. Further, this paper discusses issues related to the nuclear fuel cycle, the treatment, and disposal strategies of nuclear waste, and the decommissioning of a nuclear power plant, all of which are issues of public concern.展开更多

They can produce high value biodiesel, bioethanol, bio-hydrogen, biogas, and that they are able to use waste water and nutrients, allowing for integration of such processes with waste treatment. Open ponds in hectares of area, could remove excess CO2 in atmosphere with photosynthesis. Large scale microalgal production in fields which are not suitable for agriculture could be a solution for CO： capturing from the atmosphere. Sea water could be used for the culture medium not to consume the fresh water. However microalgae reduce the atmospheric CO： while producing the organic material, using the biomass for either fuel production or food, feed, fertilizer, come out with CO2 release to the atmosphere, when burned by the engine, body and/or bacterial activities. So, microalgal growth can＇t reduce the CO2 however makes an important contribution to keep the atmospheric CO2 level stable. Long term solution for removing the CO2, could be possible with making durable biomaterials with microalgal biomass and capture the atmospheric CO2 by fixing into the materials and interrupt the carbon cycle for a long while.展开更多

The present study deals with methods which are used to capture and utilize it in hard coal mines. It is of great importance to know that at present, ethane recovered in operating mines is obtained only through drainage systems whose implementation is enforced by health and safety regulations. Because of the fact that the amount of methane released in hard coal mines is expected to rise in years to come, as the methane content of coal seams increases with depth, heavy emphasis should be placed on methane recovery and the practical applications of the captured gas. If mine gas was officially recognised as a primary source for producing ＂environmentally friendly electricity＂, would open the perspectives of increasing methane utilization. In addition, the mining industry would gain an incentive to intensify methane recovery. It would be possible to carry out additional work focused on methane drainage from excavations which are not operated. Also, the costs of methane drainage could be included in the costs of energy production, which would undoubtedly have a positive effect on the profitability of mining companies.展开更多
