Exploration And Development

Under the background of China’s energy structure optimization, environmental protection, energy conservation, and rising pressure of emission reduction, geothermal, as a potential strategic replacement energy, has ushered in new opportunities and challenges. This paper systematically summarizes the domestic achievements in the exploration and development of geothermal resources, analyzes the endowment, distribution, and accumulation mechanism of geothermal resources in China, and points out the main problems existing in the exploration and development of geothermal resources in China. On this basis, it looks forward to China’s urgent geothermal exploration and development work and key technologies to be urgently developed, providing important guidance for China’s geothermal science and technology innovation and rapid industrialization development.

Application of biochars to soils is suggested as an effective way for improving soil quality and mitigating greenhouse gas emissions, which has generated great interest for scientists and policy makers. However, studies of biochar mainly focused on the basic mechanisms of interactions between biochars and soils. The evaluation of macro development prospect of biochar technology in China is much limited. The method of SWOT (Strength, Weakness, Opportunity and Threat) analysis was used to evaluate the prospect of biochar technology in China. The results indicate that biochar technology has great advantages and potentials in carbon emission reduction, agricultural production improvement, environmental protection and the energy structure optimization. Still, some weaknesses and environmental risk also need to be carefully considered. Finally, some suggestions for the application and promotion of biochar technology in China were provided for development of biochar industry in China.

Exploration And Development

Shale gas exploration and development in alleviating energy supply pressure, and low carbon economy development and adjusting and optimizing the energy structure has the effect which cannot ignore. As the north American shale gas exploration and development of the huge success, the domestic study of shale gas is also rapidly developed. So to understand shale gas geology difference at home and abroad, from accumulation mechanism, geological characteristics, the exploration method of shale gas geological theory has carried on the summary and analysis of the system. Contrast the research progress of north American shale gas, and the problems existing in the analysis in the study of shale gas in China, to select the most conducive to China's shale gas exploration and development methods. In this way it can make the success of shale gas development in China become a reality as early as possible.

Per Capita

This paper combines Theil index method with factor decomposition technique to analyze China eight regions’ inequality of CO2 emissions per capita, and discuss energy structure, energy intensity, industrial structure, and per capita output’s impacts on inequality. This research shows that: (1) The trend of China regional carbon inequality is in the opposite direction to the per capita CO2 emission level. Namely, as the per capita CO2 emission levels rise, regional carbon inequality decreases, and vice versa. (2) Per capita output factor reduces regional carbon inequality, whereas energy structure factor and energy intensity factor increase the inequality. (3) More developed areas can reduce the carbon inequality by improving the energy structure, whereas the divergence of energy intensity in less developed areas has increased to expand the carbon inequity. Thus, when designing CO2 emission reduction targets, policy makers should consider regional differences in economic development level and energy efficiency, and refer to the main influencing factors. At the same time, upgrading industrial structure and upgrading energy technologies should be combined to meet the targets of economic growth and CO2 emission reduction.

Kaya Identity

This paper employs an extended Kaya identity as the scheme and utilizes the Logarithmic Mean Divisia Index (LMDI II) as the decomposition technique based on analyzing CO2emissions trends in China. Change in CO2emissions intensity is decomposed from 1995 to 2010 and includes measures of the effect of Industrial structure, energy intensity, energy structure, and carbon emission factors. Results illustrate that changes in energy intensity act to decrease carbon emissions intensity significantly and changes in industrial structure and energy structure do not act to reduce carbon emissions intensity effectively. Policy will need to significantly optimize energy structure and adjust industrial structure if China’s emission reduction targets in 2020 are to be reached. This requires a change in China’s economic development path and energy consumption path for optimal outcomes.

There are abundant geothermal resources in the Xiong’an New Area, China. However, the thermal state and geothermal energy accumulation mechanism are not clear. Based on the geological conditions and the characteristics of the present geothermal field, a 2D model was established to analyze the process of mantle-derived heat conduction and to predict the distribution of the deep geothermal field. We calculated the terrestrial heat flow for the Rongcheng uplift and Niutuozhen uplift to be 64 and 75 mW/m2, respectively. The geothermal resources in this area are controlled by a four-element model comprising heat conduction, structural uplift, large deep fractures, and convection within the reservoir.
