...biochar shows versatile physicochemical properties and, can have a wide applicability in diverse fields. Comprehensive studies have been made to characterize biochar produced from various biomass materials, using different production technologies and under different process conditions. However, research...

...stability of energy systems when the share of renewable energy forms (wind and solar) is increasing. Liquid air energy storage (LAES) is a promising technology for storing electricity with certain advantages, such as high energy density and being geographically unconstrained. However, one drawback of a standalone...

The amount of wind power and other timevariable non-dispatchable renewable energy sources (RES) is rapidly increasing in the world. A few power systems are already facing very high penetrations from variable renewables which can surpass the systems' consumption during no-load periods, requiring the energy...

NOWITECH WP5 regarding analysis of access technology and logistic support. The report gives a short overview of the main aspects analysed in the research. In detail, it will present the models developed and applied for evaluation of access technology and logistics support. The results of the research cover...

HVDCs that consist of three or more terminals. This solution suits certain applications such as the large-scale integration of remote renewable sources and the interconnection of asynchronous AC regions. One of the most desirable features of meshed MTDC systems is the ability to increase the reliability...

...(R290), isobutane (R600a), and propylene (R1270), is extended by experimental tests in a smooth tube and two microfinned tubes with an increase of heat exchange area of 1.51 and 2.63, respectively. The outer diameter for all of the test tubes was 5 mm. Heat transfer coefficient and pressure drop are compared...

...hurricanes, earthquakes, wildfires, etc. are felt most acutely at local and regional levels. These events have exposed weaknesses in how well-prepared infrastructure operators are to keep their services and provide resilient responses. Outages and service disruptions are largely due to the inability of the affected...

...sample volume was regulated to 0, 20, 40 and 60degC, where 0degC is below the freezing point of cyclohexane (6degC). A sensitive differential charge measurement, with sensitivity down to 0.1 pC, and a photomultiplier was used to study the discharges in the liquid and solid phase. Streamer inception probabilities...
