Linear programing formulation of a high temporal and technological resolution integrated energy system model for the energy transition

open access: yesMethodsX, 2022
Models with a wide technological representation of energy systems can hardly adopt hourly resolutions to study the energy transition towards low-carbon technologies due to extended problem size.

Numerical Model of Cloud-to-Ground Lightning for PyroCb Thunderstorms

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
This paper demonstrates a 2-D numerical model to represent two conceptual pyrocumulonimbus (pyroCb) thundercloud structures: i) tilted dipole and ii) tripole structure with enhanced lower positive charge layer, which are hypothesized to explain the ...

Energy Transition

open access: yesDiffuse Cities and Urbanization Network, 2021
This book presents both the importance of energy transition and its associated difficulties. Providing an explanation of the physical concepts of energy and power, the book reviews global energy consumption and our dependence on energy. It discusses the links between the economy and energy.

An efficient blade sweep correction model for blade element momentum theory

open access: yesWind Energy, 2022
This article proposes an efficient correction model that enables the extension of the blade element momentum method (BEM) for swept blades. Standard BEM algorithms, assuming a straight blade in the rotor plane, cannot account for the changes in the ...

Influence of passivating interlayers on the carrier selectivity of MoOx contacts for c-Si solar cells

open access: yesEPJ Photovoltaics
The application of molybdenum oxide (MoOx) as a hole-selective contact for silicon-based solar cells has been explored due to superior optical transmittance and potentially leaner manufacturing compared to fully amorphous silicon-based heterojunction ...

Continuous multi-column sorption-enhanced dimethyl ether synthesis (SEDMES): Dynamic operation

open access: yesFrontiers in Chemical Engineering, 2023
In this work the continuous production of dimethyl ether (DME) by sorption-enhanced DME synthesis (SEDMES) technology has been demonstrated for the first time with a multi-column test-rig. A continuous single-pass carbon yield up to 95%, higher than ever

Energy Crises – Energy Transition Driving Force

open access: yes2023 International Conference on Electromechanical and Energy Systems (SIELMEN), 2023
The geographical distribution of energy resources on the territory of a limited number of countries allows them to hold a monopoly and dictate the regulations in the fuel markets, subsequently often causing energy crises. These, as a result, are leading to economic crises, food crises, and social crises.

A framework for optimisation and techno-economic analysis of CO2 pressurisation strategies for pipeline transportation

open access: yesScience and Technology for Energy Transition
This paper presents a framework for optimisation and techno-economic analysis of various pressurisation pathways for CO2 pipeline transportation. The pressurisation pathways include a conventional compression only case from initial to final pressure, a ...
