Recovery And Reuse

Climate change caused by greenhouse gases is receiving worldwide attention. CO2 (carbon dioxide) emission accounts for 80% of greenhouse gas emissions. The current measures against emission of CO2 are mainly control of emissions, sequestration and fixation, but CO2 emission decreased by only 1.6% in Europe during the past decade. CO2 recovery and reuse may offer new options for the greenhouse gas strategy. CO2 recovery technology such as the amine process is economically and technically feasible for industrial-scale application, and the recovered CO2 can be utilized for energy production, development of new energy resources, agriculture, etc. Recycling of CO2 on a large scale is discussed in this paper.

In recent years, with the intensification of environmental damage, mankind is at a crossroads towards the next energy revolution. Hydrogen energy, because of its pollution-free nature, has become the focus of technological research and development in many countries, and the economic pattern around it is taking shape China’s investment in the field of new energy has been increasing in recent years, and the prospect of hydrogen economy has prompted China to continuously increase the development of hydrogen energy. However, it faces many obstacles, both technical and social. The Chinese government is now using financial subsidies to help hydrogen companies incubate. However, with the development of the industry, China is currently facing great obstacles in large-scale commercial application, intellectual property protection and innovation, standardization construction and social confidence. This paper believes that policy measures such as selective commercial distribution, innovation system building, industry standardization construction and social education can be adopted to help solve these challenges

Near Term

Because of the near-term risk of extreme weather events and other adverse consequences from climate change, and, at least in the longer term, global fossil fuel depletion, there is world-wide interest in shifting to noncarbon energy sources, especially renewable energy (RE). Because of possible limitations on conventional renewable energy sources, researchers have looked for ways of overcoming these shortcomings by introducing radically new energy technologies. The largest RE source today is bioenergy, while solar energy and wind energy are regarded as having the largest technical potential. This paper reviews the literature on proposed new technologies for each of these three RE sources: microalgae for bioenergy, photolysis and airborne wind turbines. The main finding is that their proponents have underestimated the difficulties facing their introduction on a very large scale.

Nowadays, haze has become a big trouble in our society. One of the significant solutions is to introduce renewable energy on a large scale. How to ensure that power system can adapt to the integration and consumption of new energy very well has become a scientific issue. A smart generation control which is called hierarchical and distributed control based on virtual wolf pack strategy is explored in this study. The proposed method is based on multiagent system stochastic consensus game principle. Meanwhile, it is also integrated into the new win-lose judgment criterion and eligibility trace. The simulations, conducted on the modified power system model based on the IEEE two-area load frequency control and Hubei power grid model in China, demonstrate that the proposed method can obtain the optimal collaborative control of AGC units in a given regional power grid. Compared with some smart methods, the proposed one can improve the closed-loop system performances and reduce the carbon emission. Meanwhile, a faster convergence speed and stronger robustness are also achieved.

Wet geothermal formations or reservoirs are of great current interest as a new energy source. Such formations have the potential for large quantities of energy at temperatures of interest for power production and other uses. In these reservoirs the ground water usually contains dissolved solids in such high concentration as to pose a serious disposal problem. For this reason and also to maintain the water table, in most cases, the water will be reinjected into the reservoir after the useful energy has been extracted. Efficient utilization of the potential of a given reservoir requires optimum location of costly producing and reinjection wells. Selection of well location must be based upon an understanding of the heat and mass flows within the reservoir. In this paper, we present some general considerations for physical modeling as well as the results obtained from a laboratory model having two wells to simulate a geothermal energy extraction loop.
