Ítem Decarbonization of the Galapagos Islands. Proposal to transform the energy system into 100% renewable by 2050(Elsevier, 2022-04) Icaza-Álvarez, Daniel; Jurado-Melguizo, Francisco; Tostado-Véliz, Marcos; Arévalo, PaulThis research presents a completely decarbonized system structured with renewable energies for the fragile ecosystem of the Galapagos Islands of Ecuador, with a horizon to the year 2050. The transition process begins with clear legal actions and allocating economic resources that clearly promote a change in the energy matrix and the transition would be achieved until the year 2050. The Galapagos Islands are the second largest marine reserve on the planet, declared a World Heritage Site in 1978 for UNESCO. The archipelago, a beautiful ecological attraction, has tourism as its main economic source. The biggest problem is in the supply of energy that mainly comes from fossil fuels, in addition to that, the smell of fuel in several places is out of tune with the harmonious nature and its species. The efforts began to be noticed when in the Archipelago the new implementations of renewable energy began to become a reality with the purpose of stopping using fossil fuels. In this sense, there is the potential to take advantage of the resources available in specific sites, especially the photovoltaic and wind solar considered in the National Plan All a Life. The change in the productive matrix from the national level also implies a change in demand, including at the transportation level with the use of electric vehicles and the use of electric stoves in homes. The purpose is that energy services in the Galapagos Islands progressively increase, on the one hand, replacing fossil fuels and on the other, supplying the growing demand with a view to 2050, taking advantage of renewable energies until reaching 100%.Ítem Design to include a wind turbine and socio-techno-economic analysis of an isolated airplane-type organic building based on a photovoltaic/hydrokinetic/battery(Elsevier, 2022-05) Icaza-Álvarez, Daniel; Jurado-Melguizo, Francisco; Tostado-Véliz, Marcos; Arévalo, PaulThis study presents an analysis of an isolated hybrid photovoltaic, hydrokinetic and wind system that has storage. The energy generated in combination of resources according to the availability on the site allows the permanent supply of electricity to an airplane-type building, the same one that serves to house people who want to get out of the stressful urban life. It is an innovative and interesting study that is being launched in Ecuador and that has the certain possibility of assigning additional resources to be replicated in different parts of the region, in addition to serving as a reference for new research in different parts of the world. It is a fantastic study that, in addition to being 100% renewable, generates development in the localities. This permanent search for new opportunities is also achieved thanks to the greater availability of equipment on the market as a very safe and flexible option. Additionally, the technical-economic study of all the components is considered for an efficient use of resources, considering the different seasons of the year. The results show that the hybrid system provides sufficient and timely energy to the load.Ítem Smart strategies for the penetration of 100% renewable energy for the Ecuadorian Amazon region by 2050(Elsevier, 2023-01-01) Icaza-Álvarez, Daniel; Arias-Reyes, Pablo; Jurado-Melguizo, Francisco; Tostado-Véliz, MarcosThis research presents a 100% renewable system configured based on its real potential and use of renewable energies for the Ecuadorian Amazon, considered one of the places with the greatest diversity of native plant species on the planet. The transition processes that are born from the central state seek to take a radical turn in the electricity sector but there is still no defined roadmap, this is where this research will allow it to be an important reference for its long-term transformation. The current system is based on fossil fuels and in this study an energy transition process is planned with the support of the EnergyPLAN tool that puts into practice the concept of intelligent energy, progressively and systematically achieving 100% renewable energy for 2050. Finally, after analyzing the results, it is concluded that the energy mix for 2050 can consider 36.47% hydro, 33.04% solar photovoltaic, 29.73% wind energy and other technologies to a lesser extent with 0.74%. Surpluses can be injected into the interconnection sites with Colombia and Peru, also achieving economic income to preserve and expand the infrastructure of the electricity sector. Decision makers can consider this study as a reference before committing economic resources and carrying out modern energy planning.
