- Power grid optimization at macroscopic level: a WEF Nexus perspective for Monterrey metropolitan area(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2021-12) Cantú Hernández, Rodrigo Alejandro; MAHLKNECHT, JURGEN; 120939; Mahlknecht, Jürgen; emipsanchez; Chuck Hernández, Cristina Elizabeth; Escuela de Ingeniería y Ciencias; Campus Monterrey; González Bravo, RamónThis project aims to develop an optimization approach to evaluate the associated systems’ power demand, including the residential, commercial, industrial, public, and agricultural users, based on the Water-Energy-Food Nexus (WEF nexus) perspective. The context for this project is the landscape of the WEF nexus involving the production and distribution of their corresponding goods under which the Monterrey Metropolitan Area (MMA) operates. This is an important case study due to the area’s contribution to the country’s development, it being Mexico’s main industrial hub. Previous efforts have only focused on the water sector concerning the other two and the food sector with the energy sector. The proposed approach seeks to identify the interrelationships among the three sectors to evaluate priorities in the management of natural resources and create a pathway to understand the dynamics of the interlinks within the conflicting resources with the energy sector as the focal point. With that said, the focus of this project is to propose an off-grid power optimization model emphasizing the integration of the water, energy, and food sectors to promote a diverse, reliable, sustainable, and sufficient grid. The proposed mathematical model accounts for economic and environmental objectives by including fixed and variable costs, optimal energy generation, and greenhouse gas emissions reduction. The most important contribution of the said model compared to other research efforts on the topic is the joint consideration of both fossil and renewable power generation technologies. All while implementing a granularity that covers: the different macroscopic tariffs and consumer segments in which both the energy and water are organized at a regional level for purposes of demand quantification and pricing calculation, the various possible cooling technologies that would be used in the appropriate power generation technologies to calculate water consumption, additional water consumption coefficients that describe the different food products that are produced in the region, additional wind and solar radiation averages per municipality, per month for the calculation of the eolic, photovoltaic and thermosolar technologies. Lastly, although possible, the off-grid power generation system has the consequence of more water and environmental accountability in the region. Nonetheless, it increases energy, water, and food security within the MMA. This would also mean a total disconnection to the CFE and the national power grid, in contrast to the hybrid system scenario, which includes almost all CFE-generated energy.
- The energy use of the macroalga pelagic Sargassum in the Mexican Caribbean(Instituto Tecnológico y de Estudios Superiores de Monterrey) García Dorantes, José Gil; MEMBRILLO HERNANDEZ, JORGE; 21703; Membrillo Hernández, Jorge; puelquio, emipsanchez; Benjamín Ordóñez Díaz, José Antonio; Membrillo Hernández, Jorge; Ganem Corvera, Ricardo; Escuela de Ingeniería y Ciencias; Campus Ciudad de MéxicoThe potential of the pelagic Sargassum as feedstock for energy and substrates production is evaluated from an engineering point of view to determine if the macroalgae is a source of renewable biomass at a large-industrial level. This alternative could be a solution to mitigation and adaptation for the influx problem in the Caribbean coastline of Mexico (and other Caribbean countries). Recent research and experiments suggest that macroalgae can be processed by biorefinery systems like Hydrothermal Liquefaction (HTL) that makes suitable the use of the Pelagic Sargassum as a source of renewable energy and a substrate of potential products and services. Two different process scenarios, with or without a heat exchanger unit, are simulated in Aspen Plus to evaluate the physical, chemical, and cost feasibility of the macroalga continuous HTL to obtain bio-crude oil, an aqueous phase, gaseous phase, and char, as valuable products at an industrial production with a potential use such as biofuel, and fertilizer. Both cases are thermodynamically, energetically, and economically evaluated with a macroalga sludge feedstock of 2.79 M t/year, a total product sales of $14.94 M USD/year, and a payback period of 5.54 years in one of the scenarios considering the total capital, and utility costs of the integrated system and its boundaries. The production of 1.87 PJ/year of energy equates to 0.05% of Mexico's primary energy production from crude oil in 2019. This study stands for an opportunity for adaptation and mitigation of the problem that is affecting the Caribbean zone, as well as for an opportunity of synergy between the scientific, private, and government sectors.
