In the US, carbon capture and storage (CCS) has received most of its attention when coupled with the fossil fuel industry as a mitigation strategy for climate change. CCS, which is constituted as a broad suite of capture and sequestration technologies and techniques, does not preclude coupling...

Reliable wind modelling is of crucial importance for wind farm development. The common practice of using sector-wise Weibull distributions has been found inappropriate for wind farm layout optimization. In this study, we propose a simple and easily implementable method to construct joint...

Hydrazine borane N<sub>2</sub>H<sub>4</sub>BH<sub>3</sub> and alkali derivatives (<i>i.e.</i>, lithium, sodium and potassium hydrazinidoboranes MN<sub>2</sub>H<sub>3</sub>BH<sub>3</sub> with M = Li, Na and K) have been considered as potential chemical hydrogen storage materials. They belong to the family of boron- and nitrogen-based materials and the present article...

Most commercial gaseous and liquid fuels are mixtures of multiple chemical compounds. In recent years, these mixtures became even more complicated when the suppliers started to admix biofuels into the petrochemical basic fuels. As the properties of such mixtures can vary with composition, there...

As offshore wind turbines move towards deeper and more distant sites, the concept of floating foundations is a potential technically and economically attractive alternative to the traditional fixed foundations. Unlike the well-studied monopile, the geometry of a floating foundation is complex...

This paper describes the design, evaluation, and implementation of a compensation scheme for a measurement voltage transformer (VT) using the hysteresis characteristics of the core. The error of a VT is caused by the primary winding voltage and secondary winding voltage. The latter depends on...

This work focused on the high pressure PCT and<i> in situ</i> neutron powder diffraction studies of the LaMg<sub>2</sub>Ni<sub>9</sub>-H<sub>2</sub> (D<sub>2</sub>) system at pressures up to 1,000 bar. LaMg<sub>2</sub>Ni<sub>9</sub> alloy was prepared by a powder metallurgy route from the LaNi<sub>9</sub> alloy precursor and Mg powder. Two La<sub>3−x</sub>Mg<sub>x</sub>Ni<sub>9</sub> samples with slightly...

The power production of the linear generator wave energy converter developed at Uppsala University is affected by variations of mean sea level. The reason is that these variations change the distance between the point absorber located on the surface and the linear generator located on the...
