The 10 most cited studies highlight the …
Spatial bayesian approach for socio-economic assessment
Pumped hydro energy storage (PHES) is a key enabler for transitioning to 100 % renewable energy sources. However, PHES site selection is multi-faceted and challenging, including from a socio-economic perspective, due to complex economic issues and the heterogeneity of social factors. To overcome this challenge, this study developed …
Spatiotemporal modelling for integrated spatial and energy …
The transformation of the energy system to a renewable one is crucial to enable sustainable development for mankind. The integration of high shares of renewable energy sources (RES) in the energy matrix is, however, a major challenge due to the low energy density per area unit and the stochastic temporal patterns in which RES are …
Spatial analyses of smart energy system implementation
The first step of the research was to develop an SD model to represent the energy sector of Latvia. Modelling was done in Stella Architect 2.1. software developed by isee systems [45].The research aimed to build a detailed energy sector model, which would include all the relevant parts of the system and describe the causalities between system …
Spatial Structure Engineering of Interactive Single Platinum Sites ...
1 Introduction. Reaction pathways and performance of heterogeneous catalytic processes are closely dependent on the atomic structure of catalysts. [] Regulating atomic interactions between each pair of active sites is an intriguing strategy to optimize catalysts'' properties. [] Despite the high exposure of active sites, nanoparticle catalysts …
PyPSA-Earth. A new global open energy system optimization …
Similarly, existing PyPSA models are geographically limited. While PyPSA as a framework is adopted worldwide by many companies, non-profit organizations and universities (see example studies in [34]), no global model solution is available.Providing a global energy system model ecosystem solution has the potential to unlock collaboration …
Design of spatial variability in thermal energy storage modules …
The energy storage or discharge rate of a TES module containing PCMs is dictated by its dynamic response to a transient thermal load, which depends on the module geometry and dimensions, the internal distribution and orientation of PCMs and thermally conductive elements, the thermophysical properties of the materials composing …
Urbanisation and energy consumption in Sub-Saharan Africa
6. Conclusion. The relationship between urbanisation and energy consumption has been studied extensively. The first investigations by Jones, 1989, Jones, 1991 reveal a positive effect of urbanisation on energy consumption: a 1% increase in urbanisation increases energy consumption by 0.35–0.48%.
Urbanisation and energy consumption in Sub-Saharan Africa
Sub-Saharan Africa has the lowest access to modern energy and highest urbanisation and population growth rates in the world. The increasing population and its move towards urban areas are expected to exert pressure on existing energy infrastructures and government budgets, introducing uncertainty in the path that future resource …
Geospatial multi-criteria analysis for identifying ...
Africa has the potential to provide for its growing energy needs with renewable electricity sources. We implement a multi-criterial geospatial optimization to locate the most favorable sites for utility-scale, grid-connected onshore wind and solar PV. Legal, technical, political, environmental, socio-economic and investment risk factors …
Water storage changes and balances in Africa observed by …
Abstract. Continental water storage plays a major role in Earth''s climate system. However, temporal and spatial variations of continental water are poorly known, particularly in Africa. Gravity Recovery and Climate Experiment (GRACE) satellite mission provides an opportunity to estimate terrestrial water storage (TWS) variations at both ...
The role of urban spatial structure in energy resilience: An …
The fact that building and transportation sectors, combined, account for about 64% of the total energy consumption in a country where 74% of the population lives in urban areas (Statistical Centre of Iran, 2016) implies that urban form and morphology, street networks, land use patterns, and generally, the spatial structure of cities could have ...
Modulation and mechanism of spatial structure for multi-layer …
Overcoming sticky problems of large dielectric loss and poor breakdown strength (E b) is prerequisite of actual applications for high dielectric constant polymer composites.Herein, three kinds of multi-layer structure composites with different spatial structures (2MP-CE/CNT, CE/CNT-2MP-CE/CNT, MP-CE/CNT-MP) were prepared …
Spatial Structures::Introduction::Knowledgebase::Structure and …
Spatial structures can be assembled in a shop and transported to the site for erection. A Typical Spatial Structure Connector (Node) The manufacturing of the connectors (or nodes) is one of the most important factors in cost-effectiveness of spatial structures. An ideal connector can be easily mass produced, used to join members at various ...
Energy distribution and spatial structure of electrosprays of ionic ...
The ionic liquid 1-ethyl-3-methyl imidazolium tetrafluoroborate (EMI + BF 4 −) is electrosprayed in a vacuum from positively charged Taylor cones, and the full sprays are analyzed by time of flight mass spectrometry (TOFMS). They contain predominantly the ions (EMI-BF 4) n EMI + (n=0,1,2), at current levels of several μA. Current versus arrival …
