“…OSeMOSYS is widely recognized as an accessible, straightforward, and quick-learning tool with many capacitybuilding resources and communities of practice [112]. Different studies have implemented OSeMOSYS to evaluate the sustainable expansion of national power systems [113][114][115][116][117][118][119][120][121][122][123][124] or the combination of power and transport sectors [119]. In addition, a recent work explored energy planning in the power sector to integrate electrolytic hydrogen dedicated to exports in Chile [125].…”

Climate change is driving the need for new approaches to energy production and utilization globally, contributing to the mitigation of greenhouse gas (GHG) emissions. Low-emission hydrogen is recognized as a key energy vector for decarbonization, and numerous countries are currently evaluating strategies and roadmaps for its integration. Colombia, with its abundant renewable resources, is poised as a potential player in hydrogen production. The study presents an integrated techno-economic assessment of hydrogen’s role within Colombian energy mix. By employing an open energy system optimization model (OSeMOSYS), we analyzed a series of hydrogen scenarios from 2021 to 2050, including a sensitivity analysis. Our results show that hydrogen pathways will require 2-6.4 Mt/year in hydrogen production, 8-27 GW in installed capacity, and US$50-80 billion in investments, with favorable impacts in GHG mitigation, energy imports, and socioeconomic benefits. We use these findings to formulate an update to the targets of the current National Hydrogen Roadmap focused on a higher ambition to deploy a full hydrogen economy. Our open methodology provides a valuable tool for conducting further assessments in countries interested in defining hydrogen roadmaps.

“…In [19,20], a performance indicator for evaluating the efficiency of power plants was proposed, which is based on the properties of productivity indicators obtained from the analysis of feasibility and thermodynamic efficiency. The efficiency indicator for the operation of a power plant within an energy system was developed using the properties of constraints and the possibility of combining different types of energy, taking into account their distinct impacts, borrowed from thermodynamics analysis.…”

The work is dedicated to addressing the issues related to assessing the efficiency of modern electrical power systems, especially as an increasing number of consumers desire to actively influence the electricity supply schedule, providing conditions to electricity producers. The research can be divided into two main segments: the development of a model for assessing the efficiency of electrical power system operation and the development of a method for analyzing the performance of the energy system, which is based on a model of changes in the quality indicators of the energy system. The proposed model takes into account properties of the energy system such as the probability of uninterrupted network operation, normalized frequency of electrical power, the volume of consumed electrical energy, and the electrical energy supplied by the transmission organization. It is expected that this model will help provide a more accurate assessment of the efficiency of energy system operation under normal operating conditions. Furthermore, a method for analyzing the efficiency of energy system operation has been developed, which is based on a model of changes in the quality indicators of the energy system. A unique featureof this method is the introduction of a new comprehensive indicator of energy system efficiency, which is determined using a convolution method of partial indicators, namely: the volume of electrical energy supply, the quality of electrical energy supply,and the efficiency of electrical energy supply. The reliability of the model was confirmed through the calculation of the daily electric supply and load schedule.

“…OSeMOSYS is designed to be fully accessible, straightforward, and transparent for supporting long-term energy modelling in academia, industry, and governments [13,[33][34][35]. The framework has widely been used to support local [36][37][38], national [9,[39][40][41][42][43][44][45][46][47][48][49], and regional [50][51][52] energy system assessments.…”

In this study, we assess plausible decarbonization pathways in Colombia using an open-source national energy system optimization model (OSeMOSYS). We build three scenarios over 2021-2050 and contrast them in terms of emissions, energy consumption, technology deployment, costs, and benefits. The results show that a decarbonized energy system can reduce carbon intensity by 93%, energy intensity by 44%, fossil fuel imports by 90%, and provide socioeconomic benefits equivalent to 21% of the Colombia's 2021 GDP. We use these results to recommend milestones and policy actions that can help inform policymakers about cost-effective strategies to achieve a sustainable, efficient, and more resilient energy system by mid-century. Our transparent and systematic methodology provides a tool for long-term energy planning in Colombia which can also be replicated in other developing countries for assessing decarbonization pathways.
