Global Programme for Hydrogen in Industry
The uncontrolled emission of greenhouse gases is one of the main challenges of the 21st century. There is a direct correlation between the CO2 and other greenhouse gases concentrations in the atmosphere and the mean global temperature, which has been rising rapidly since the onset of the Anthropocene, due to human demand for energy.

Saudi Arabia’s Potential to Enhance its Position as a Key Goods’ Provider for the Energy Transition and the Upcoming Hydrogen Economy
Saudi Arabia is undergoing a fundamental and ambitious energy transition by diversifying its energy mix. Despite the fact that the oil and gas sectors still accounts for about 50% of the gross domestic product (GDP), and more than 70% of export earnings, the Kingdom is investing heavily in alternative energy sources in order to adapt to a potential decline in global demand for conventional oil and gas products over the next decades. In this regard, Saudi Arabia is positioning itself as a new regional and global hub for hydrogen and pushes its efforts to develop comprehensive capacities to export clean hydrogen1 (and derivatives) to global markets.

ASME B31.3: Process Piping
The realization of the need for codes did not become apparent until the invention of the steam engine. The first commercially successful steam engine was patented by Thomas Savery of England in 1698. The Savery engine, and the numerous improved engines which followed, marked the beginning of the industrial revolution. This new economical source of power was used to drive machines in factories and even enabled new and faster forms of transportation to be developed.

Fundamentals of Modern Electrical Substations – Part 1, Part 2, Part 3
Part 1 of this course series is concentrated on demonstrating how modern power systems are arranged to accomplish all these goals; what place electrical substations have in the overall power system structure; and how important they are for reliable and effective operation of power systems. Part 2 of the course “Fundamentals of Modern Electrical Substations” is concentrated on substation auxiliary and control systems which play a major role in allowing all station equipment to function properly, thus, fulfilling the main substation mission to support reliable and effective operation of power systems. Part 3 of the course “Fundamentals of Modern Electrical Substations” is concentrated on substation engineering aspects, which may be very challenging and require from utility companies engineers a very diverse knowledge and experience to address these aspects.

A Data-Driven Digital Twin for Water Ultrafiltration
Membrane-based separations are proven and useful industrial-scale technologies, suitable for automation. Digital twins are models of physical dynamical systems which continuously couple with data from a real world system to help understand and control performance. However, ultrafiltration and microfiltration membrane separation techniques lack a rigorous theoretical description due to the complex interactions and associated uncertainties. Here we report a digital-twin methodology called the Stochastic Greybox Modelling and Control (SGMC) that can account for random changes that occur during the separation processes and apply it to water ultrafiltration. In contrast to recent probabilistic approaches to digital twins, we use a physically intuitive formalism of stochastic differential equations to assess uncertainties and implement updates. We demonstrate the application of our digital twin model to control the filtration process and minimize the energy use under a fixed water volume in a membrane ultrafiltration of artificially simulated lakewater. The explicit modelling of uncertainties and the adaptable real-time control of stochastic physical states are particular strengths of SGMC, which makes it suited to real-world problems with inherent unknowns.
