The Sines H2 Hub aims to take advantage of Portugal’s solar resources and push for a green hydrogen hub centred in Sines. To do so, a 1GW electrolyser is expected to be built by 2030. The gas produced, which will have the same production profile as the solar irradiance, can be injected in the gas grid, distributed by truck or shipped to the...

Exploiting the information provided by electron energy-loss spectroscopy (EELS) requires reliable access to the low-loss region where the zero-loss peak (ZLP) often overwhelms the contributions associated to inelastic scatterings off the specimen. Here we deploy machine learning techniques developed in particle physics to realise a model...

With the advent of large-scale application of hydrogen, transportation becomes crucial. Reusing the existing natural gas transmission system could serve as catalyst for the future hydrogen economy. However, a risk analysis of hydrogen transmission in existing pipelines is essential for the deployment of the new energy carrier. This paper...

High efficiency air filtration has been suggested to reduce airborne transmission of ‘infectious’ aerosols. In this study the ‘air cleaning’ effect as well as the effect on sound and air velocity (draught risk) of a mobile High-Efficiency Particulate Air (HEPA) filter system was tested for different settings and positions in the Experience room...

Underwater noise pollution generated by offshore pile driving has raised serious concerns over the ecological impact on marine life. To comply with the strict governmental regulations on the threshold levels of underwater noise, bubble curtains are usually applied in practice. This paper examines the effectiveness of an air bubble curtain...

Fault location algorithms for transmission lines use the parameters of the transmission line to locate faults after the faults have occurred along the line. Although these parameters can be estimated by the phasor measurement units (PMUs) at the terminal(s) of the transmission line continuously, the uncertainty in the measurements will give...

This paper analyzes high-frequency interactions between a Modular Multilevel Converter (MMC) and High Voltage Direct Current (HVDC) grid resonances by studying their effect on the system stability. The recent appearance of converter-related instabilities due to high-frequency oscillations at the converter's ac side raises concerns about whether...

Destructive consequences of trapped space charges within HVDC coaxial cable insulation, such as accelerated aging, degradation, and breakdown, are some of the most significant challenges that manufacturers and users usually come up with. Pulsed Electro-Acoustic (PEA) method is a widely-used method for space charge detection and measurement, in...

The object of this thesis work was to develop a (Monte Carlo) simulation package that can be used to aid in the design of the Timed Photon Counter (TiPC). The TiPC is a single photon detector whose working principle is based upon the multiplication of an electron signal by transmission dynodes, or tynodes. For TiPC to be feasible, it is...

Environmental and political factors determine long-term development for renewable generation around the world. The rapid growth of renewable generation requires timely changes in power systems operation planning, investments in additional flexible assets and transmission capacity. The development trends of restructured power systems suggest that...

In this research OpenFOAM is used to model and determine the complex hydrodynamic behaviour of a Homogeneous low-crested structure (HLCS) consisting of cubipod artificial concrete elements. The validated model is used to gain insight in the design sensitivities of a two dimensional cross sectional layout to reduce sea wall overtopping. HLCS and...

The power system in Northern Europe supports a high degree of penetration of Wind Energy-based HVDC connections. Most of the modern HVDC connections will have Bipole with a dedicated metallic return (DMR) configuration. This thesis presents a basic guideline to increase the Levelized cost of operation of Bipole HVDC links by attaching the...

The pulsed electromagnetic (EM) field transfer between a horizontal electric dipole (HED) and a transmission line is described analytically with the aid of the time-domain (TD) reciprocity theorem and the Cagniard-de Hoop technique. A suitably chosen wave-slowness representation makes it possible to cast the pertaining interaction integrals...
