Title Renewable energy transition: a market-driven solution for the energy and environmental concerns in Chile Type
Year 2018 Publication Clean Technologies And Environmental Policy Abbreviated Journal Clean Technol. Environ. Policy
Volume 20 Issue 1 Pages 3-12
Keywords Energy transition; Energy policy; Renewable energy technologies; Chile
Abstract Chile is undergoing a remarkable energy matrix transition to renewable energy. Renewable energies are expanding extraordinarily fast, exceeding earlier predictions. As a result, the country is expected to meet its 2025 goal of generating 20% of its electricity from renewable energy sources quite before. Chile has become one of the first countries in the world with subsidy-free markets, where renewable projects compete directly with other conventional sources. Favorable market conditions and successful policy reforms were keys to fostering this renewable energy development. Although the country has achieved a substantial growth in renewable energy investment in a relatively short period of time, this optimism should be treated with caution. A successful transition requires a combination of a clear decision making, persistent and consistent government policies, and a clear commitment to tackling challenges to accommodate renewable energy in the power system. In this context, this paper analyses the Chilean renewable industry and the required government policies to succeed in this transition. For this purpose, we identify several critical factors that have attracted and that could attract investment to the renewable energy sector and propose key recommendations to effectively address the major challenges faced for the future development of the industry.

Title Expansion of renewable energy in Chile: Analysis of the effects on employment Type
Year 2021 Publication Energy Abbreviated Journal Energy
Volume 226 Issue Pages 120410
Keywords JOB CREATION; TECHNOLOGIES; POWER; WIND
Abstract Over the last few years, Chile has witnessed an extraordinary energy transformation that has turned the country into one of the largest renewable energy markets in South America. This study examines the impact of renewable energy (RE) technologies from the perspective of job creation opportunities in Chile. For this purpose, the study introduces an analytical assessment model that will be used to assess the direct impacts on employment generated by several policy scenarios aimed at reducing CO2 emissions. The direct impacts on employment in Chile were calculated up to 2026 according to three energy scenarios constructed using the SWITCH-Chile energy model. The empirical results show that RE technologies (solar PV, wind, hydro) can generate more employment per unit of energy than coal and natural gas. According to the scenario projecting the largest reduction of CO2 emissions, which features a dominant participation of renewable energies, up to 20,958 jobs can be created in the Chilean energy sector by 2026. The proposed model can be used to design energy programs as a direct stimulus of employment in the RE industry. Furthermore, policy recommendations are provided based on the results to effectively address changes in employment perspectives for the RE industry. (C) 2021 Elsevier Ltd. All rights reserved.

Title Graphene modified “black {001}TiO2” nanosheets for photocatalytic oxidation of ethylene: The implications of chemical surface characteristics in the reaction mechanism Type
Year 2022 Publication Separation And Purification Technology Abbreviated Journal Sep. Purif. Technol.
Volume 292 Issue Pages 121008
Keywords Black TiO2 NSTs; Ethylene; Photocatalytic oxidation; Postharvest technologies; Reduced graphene oxide
Abstract In this work, crystal facets, bandgap, size and shape of reduced graphene oxide (rGO) modified anatase {001} black TiO2 nanosheets (rGO-B-TiO2 NSTs) were tailored for the photocatalytic oxidation of ethylene under high humidity content. XRD, Raman and HR-TEM analyses confirm that rGO-B-TiO2 NSTs have a 94 % of exposed {001} facets with high number of oxygen vacancies. In addition, rGO-B-TiO2 NSTs exhibit increased values of surface area and porosity compared to its pristine form. A 48 and 34 mu mol g(-1) of ethylene are adsorbed at the surface of rGO-B-TiO2 NSTs in the absence and in the presence of humidity, respectively. In addition, operando DRIFTS analyses provide the insight of surface interactions between ethylene molecules and adsorption sites of rGO-B-TiO2 NSTs. The photocatalytic removal efficiencies of the synthesized materials under both UV and visible light irradiation proceed as follows: rGO-B-TiO2 NSTs > B-TiO2 NSTs > TiO2 NSTs > commercial TiO2 NPs. Further, ethylene is very quickly photocatalytic oxidized when rGO-B-TiO2 NSTs is applied under UV light irradiation, having a 72 and 92 % ethylene removal in the absence and in the presence of humidity, respectively. Moreover, a 48 and 58 % of ethylene removal takes place in the absence and presence of humidity under visible light irradiation, respectively. Results indicate that rGO-B-TiO2 NSTs boost the photocatalytic activity through their virtue of visible-light absorption properties (Bandgap = 2.61 eV) and the rapid electron-hole separation at the rGO {0 0 1} black TiO2 NSTs interfaces. Such findings are confirmed through UV-visible diffused reflectance, photoelectrochemical and photoluminescence analyses. Nanosheets made of rGO modified {0 0 1} black TiO2 could be used as an effective photocatalyst for the removal of ethylene from large volume fruit storage areas by exploiting a simple light source in the presence of high content of humidity.
