    Description: A medida que el presupuesto mundial de carbono disminuye rápidamente, los países de todo el mundo buscan soluciones para limitar las emisiones de gases de efecto invernadero. Dado que la producción y el uso del carbón son algunos de los procesos más intensivos en emisiones carbono, es previsible que las regiones que producen carbón se vean especialmente afectadas por las consecuencias de una transformación hacia la neutralidad climática. Estas regiones se enfrentan a retos en el ámbito de la producción de energía y la protección del medio ambiente, pero también a retos económicos y sociales, que se engloban en la necesidad de una "transición justa". Los responsables de la toma de decisiones en las regiones dependientes de la producción de carbón necesitan urgentemente herramientas de apoyo que ayuden a poner en marcha medidas para diversificar las economías locales y, al mismo tiempo, apoyar a los trabajadores y las comunidades locales. Wuppertal Institute busca apoyar a las regiones carboníferas de todo el mundo desarrollando una caja de herramientas para la transición justa, que ilustra los retos y las oportunidades de una transición sostenible para un público global. La caja de herramientas incluye recomendaciones para el desarrollo de estrategias y estructuras de gobernanza, líneas guía para la creación de empleo sostenible, el desarrollo de alternativas tecnológicas, la rehabilitación medioambiental y la reutilización de infraestructuras relacionados con el carbón. La caja de herramientas se basa parte del trabajo de Wuppertal Institute dentro de la Iniciativa de la UE para las Regiones Carboníferas en Transición y tiene en cuenta las circunstancias específicas de los países socios de la SPIPA: India, Indonesia, Sudáfrica, Japón, Corea del Sur, Canadá y Estados Unidos. El acrónimo SPIPA es la abreviatura de "Asociaciones Estratégicas para la Aplicación del Acuerdo de París", un programa UE-BMU cofinanciado por la GIZ.

    Description: Para lograr una transición hacia el desarrollo sostenible son fundamentales la ciencia y la educación, especialmente la educación superior. Se necesitan formatos educativos para capacitar a los estudiantes en la realización de investigaciones transformadoras. Con base en la investigación transdisciplinaria y transformadora en laboratorios del mundo real y estudios del futuro, desarrollamos un módulo de aprendizaje y enseñanza integral: el Laboratorio de Innovación Transformadora (lit). El laboratorio desarrolla cinco competencias clave y tres tipos de conocimiento necesarios para impulsar innovaciones en sostenibilidad socialmente robustas. En este artículo se presentan las principales características de este formato vivencial y reflexivo, además de un manual para facilitar el laboratorio. También se comparten y discuten los aprendizajes centrales de la implementación de este formato en programas de estudio existentes a partir de dos pruebas realizadas en dos universidades alemanas.

    Description: The Changning MS6.0 earthquake and its moderate to strong aftershocks, which occurred in the axial area of Changning anticline, exhibit different features with the moderate to strong earthquakes that occurred in the southern syncline area nearby, although these two areas are only a dozen kilometers away. Whether this difference is only caused by different fault structures, or caused by local change is still a matter of debate. In order to answer this question, basing on the correction of small earthquake location and seismic velocity structure through double-difference tomography inversion, this paper determined the fine structure of the crustal stress field by using comprehensive focal mechanism solutions, and analyzed its mechanical consistency with the focal mechanism solutions of moderate to strong earthquakes. It is found that for the different subareas of Changning area, the maximum principal stress remains horizontal, and its azimuth remains almost East-West oriented although it has a small clockwise rotation from north to south; meanwhile, the stress regime exhibit a significant local change, which is thrust stress regime for the axial area of Changning anticline, against strike-slip stress regime for the southern syncline area. The stress fields in these two subareas highly accord with the focal mechanism solutions of moderate to strong earthquakes in the corresponding area, but poorly accord with, or even contradict that in the non-corresponding area, which indicates that the local stress change of stress field is the necessary mechanical basis for the complex seismicity behavior in Changning area. Additional rock mechanics analysis points out that lateral difference of Poisson's ratio of rock is probably the main cause of this local change of stress field. This paper also discusses the seismogenic fault structure of Changning MS6.0 earthquake sequence, and suggests the activation of the basement fault(s) in the depth range of 6 to 9 km in the axial area of Changning anticline driven by regional stress field is the potential cause of the occurrence of Changning MS6.0 earthquake sequence.

    Description: For a long time, with the continuous expansion of the oil and gas genesis theory and the increasing global demand for clean energy, hydrogen, as an important link connecting the theory of inorganic and organic hydrocarbon generation, as well as a promising clean energy, has gradually attracted widespread academic attention. The genesis of hydrogen in natural gas is relatively complex and diverse. According to its reaction mechanism, it can be divided into two categories: inorganic and organic. Inorganic genesis is mainly earth degassing, water rock reaction and water radiation decomposition, while organic genesis is dominated by biological action and organic matter pyrolysis. At present, hydrogen isotope and geochemical characteristics of associated gases are mainly used to identify the origin of hydrogen. However, due to the complex and diverse sources of hydrogen and its active chemical properties, it is still unable to identify the origin of hydrogen systematically and accurately. Due to the extensive genesis of hydrogen, natural gas with different hydrogen concentrations has been found in different geological conditions around the world, and the hydrogen content varies greatly (0.1%-99%). Hydrogen can participate in hydrocarbon generation in Fischer Tropsch synthesis as a reducing agent, and also can be used as a hydrogen source to improve the hydrocarbon yield during the thermal evolution of organic matter. Therefore, the existence of hydrogen may extend the lower limit of deep gas exploration and development. Based on the systematic summary of the genetic mechanism and distribution of hydrogen, this paper discusses the energy significance of hydrogen in natural gas, and provides a reference for the future research on hydrogen rich natural gas resources.
