Data article: Wind and power density data of strategic offshore locations in the Colombian Caribbean coast

Manuscript title: Wind and power density data of strategic offshore locations in the Colombian Caribbean coast

Authors: Juan Gabriel Rueda-Bayona, Andrés Guzmán, Juan José Cabello Eras

Data in Brief. December 2019. Vol. 27, 104720. https://doi.org/10.1016/j.dib.2019.104720

Abstract: The high potential of wind speed in the Colombian Caribbean coast is an opportunity to develop offshore wind energy technology. This article contains the wind speed and wind power density in four strategic locations in Colombia (Cartagena, Barranquilla, Santa Marta and La Guajira) at different elevations. The dataset from this study is related to the research paper “Renewables energies in Colombia and the opportunity for the offshore wind technology published in Journal of Cleaner Production (Rueda-Bayona et al.) [1]. Reading and processing numerous files stored in databases could be challenging because it demands software programming to do so, what could difficult the access to valuable data for the community. Also, high compressed files such as NetCDF formats demand specialised software which is not easy obtaining and utilising because it requires skills in a programming language. Then, this study used the NARR-NOAA database [2] and generated local wind and power density data stored in Excel sheets to ease their utilisation.

Data article: Set-up and input dataset files of the Delft3d model for hydrodynamic modelling considering wind, waves, tides and currents

Manuscript title: Set-up and input dataset files of the Delft3d model for hydrodynamic modelling considering wind, waves, tides and currents through multidomain grids

Authors: Juan Gabriel Rueda-Bayona, Andrés F. Osorio,  Andrés Guzmán

Data in Brief. December 2019. Vol. 28, 104921. https://doi.org/10.1016/j.dib.2019.104921

Abstract: This article contains the set-up and input files of the implementation of Delft3D model to determine extreme hydrodynamic forces performed in Rueda-Bayona et al. [1]. The model was configured with a multidomain grid using double-way communication between the hydrodynamic and wave module. The multidomain grids solve faster than single and nested grids because require less grid points to calculate. Also, the double-way communication between the hydrodynamic and wave modules allows to consider the non-linear interactions of wind, waves, tides and currents. Because there are no modelling examples related to multidomain grids in the open access official web site of Delft3d model, this data contributes to increase the availability information of this necessity. Finally, the files of this article are ready to be run in the Delft3D model to perform a sensitivity test recommended in Rueda-Bayona et al. [1].

Abstract: Human activity, mainly associated with the construction of coastal infrastructure, has caused ecological degradation to the coastal zone at Puerto Colombia, Colombia. Severe erosion attacked the ancient sandy spit that protected the municipality from wave energy to an extent that it completely disappeared. The groins constructed thereafter, with the aim of protecting the coast, have exacerbated the sediment imbalance, affecting the Balboa coastal wetland. At present, the coastline around Puerto Colombia is highly vulnerable; the remaining ecosystems are under severe pressure, and the population is at risk. Restoring the marine and terrestrial connectivity is key to improving this situation.

Review Article: Renewables energies in Colombia and the opportunity for the offshore wind technology

Review Article: Renewables energies in Colombia and the opportunity for the offshore wind technology

Journal of Cleaner Production, In Press (February 2019)

Abstract:

Global offshore wind technology shows increasing progress evidenced in the recent reports of wind power capacity, expectations of market expansion and international research projects. Colombia is privileged with several types of natural resources (e.g. wind, sun, water) but there is not a clear legal context to regulate sustainable and safe exploitation of the offshore wind energy considered non-conventional. The development of offshore wind technology in Colombia could attend the energy demand when the hydroelectric system presents low electricity generation during dry hydrological conditions and El Niño – South Oscillations events. This paper analyses international actions that have motivated different countries to establish strategies to reduce CO2, and their advances and challenges in implementing offshore wind technology. The review of the administrative framework of renewable energy in Colombia proved the lack of information for implementing offshore wind technology. Furthermore, the analysis of several studies of marine energies showed the need to increase the knowledge of offshore wind energy.

The local applying projects to generate electricity from non-conventional renewable energies are not considering offshore wind energy projects. Hence, this research analysed wind speed and calculated wind power density at different height levels, what evidenced magnitudes and positive trends what justify to increase the research in offshore wind energy in Colombia. As a result, the present document compiles technical, economic, administrative and legal information of the renewable energies in Colombia that may be used for taking decisions of different stakeholders and evidences the potential implementing offshore wind farms in areas near to the Colombian Caribbean coast. Colombia has great resources to implement offshore wind energy technologies, reducing the dependence on fossil fuels and substituting other systems when they cannot guarantee the energy offer.

Reuso de residuos para constituir materiales de construcción

Quiero compartir con ustedes el artículo preparado a la revista Intellecta de la Universidad del Norte y divulgado a nivel nacional, sobre los trabajos realizados de la mano del profesor Pacheco y vinculados al desarrollo de maateriales de construcción que contemplan el reuso de residuos de otros procesos (industriales y de consumo).
