La apuesta cada vez más generalizada por combinar energías renovables y sistemas de almacenamiento en las llamadas plantas de generación híbridas requiere del uso de tecnologías 4.0 y técnicas avanzadas de control y optimización para maximizar su rentabilidad y afianzarlas en el mercado. Este artículo resume varios de los retos y oportunidades que existen a nivel tecnológico en el control de las plantas de generación híbridas con almacenamiento para conseguir nuevas fuentes de suministro eléctrico más sostenibles y rentables en los países de la Unión Europea.

Este trabajo muestra el desarrollo de materiales alternativos, libres de materias críticas, preparados por técnicas de fácil escalado industrial, y su aplicación en dispositivos de generación de energía limpia y sostenible. El principal objetivo es contribuir en la resolución de un reto social de disponer de una energía segura, eficiente y limpia, gracias a la innovación en dispositivos fotovoltaicos empleando materiales no convencionales.

La captura, uso y almacenamiento geológico de CO2 (CCUS; Capture, Use and Storage, según el acrónimo en inglés, o CAUC, Captura, Transporte, Almacenamiento y Uso del CO2, en su acrónimo castellano) es una tecnología que proporciona una solución viable para un futuro sostenible, puesto que incide directamente en el problema que presentan los combustibles fósiles: las emisiones de CO2. Permite minimizar las emisiones y seguir consumiendo combustibles fósiles; ataca y resuelve el problema.

Hydrogen, while still being an essential reactant in oil refining to produce clean hydrocarbon fuels, will play a fundamental role as sustainable fuel to reach global decarbonisation in 2050. National and international, institutional and private collaboration and initiatives must and are facilitating the transition.

This article analyzes the role that green hydrogen maintains in the current industrial sector. In addition to analyzing the characteristics of this clean fuel, and answering the questions that arise in the face of what has come to be called the “hydrogen boom”, the author dwells on the technological challenges involved in its implementation and the answers that are offering the industry for the equipment of a green hydrogen plant.

Energy has been the basis of economic prosperity of developing and industrialized nations in the last decades. The energy demand continues to grow steadily and replacement of fossil fuels by renewable sources is an issue for both, policy makers and the public. This transition will involve massive investments in research, technological development, and new processes.  An overview of these factors is given in this study.  Among scientific and engineering areas, Chemical Engineering will play a key role to obtain alternative liquid fuels with low CO2 emissions, in a competitive economic environment.

Sustainability has become one of the biggest concern for the industry, due to their need to maintain their reputation as well as their bottom line. On other hand the stock market is is rewarding those companies that include sustainability as one of their main strategies. This challenge is particularly important for Chemist and Oil&Gas companies. For example, chemical industry is under particular pressure because it is the foundation of sustainability in many other industries like agriculture and fertilizers, housing, plastics, and pharma.

Although the current trend in Fine and Specialty Chemistry is to gradually replace traditional semi-batch processes with Flow Chemistry processes, which are safer, cleaner, and faster, most production continues to be semi-batch. This paper is devoted to recovering the basic concepts of thermal safety of such semi-batch processes.

As the internet is exponentially permeating daily life and work, in parallel, different events of cyberattacks have been recorded. There is a huge challenge nowadays on how to deal with them in the industrial sectors, especially in those with an associated high risk on safety, environment or significant socio-economic impact (i.e. strategic energetic facilities, etc.).

The following article is a case study. We focus on the definition of different phases of a high potent product handling project under isolator. The processes to be carried out in the isolator environment will be the weighing of products, with exposure limits of 0,01 µg/m3. During the project, we will analyse the different phases that will allow us to adequately assess the risks and select the appropriate mitigation mechanisms.
