    • Anindito, Yoga; Haas, Jannik; Olivares, Marcelo; Nowak, Wolfgang; Kern, Jordan (Elsevier, 2019)
      Hydropower plants frequently operate at high output during peak hours and at low output (or even shutoff) during off-peak hours. This scheme, called "hydropeaking", is harmful to downstream ecosystems. Operational constraints ...
    • Haas, Jannik; Moreno Leiva, Simón; Junne, Tobías; Chen, Po-Jung; Pamparana, Giovanni; Nowak, Wolfgang; Kracht Gajardo, Willy; Ortiz, Julian (Elsevier, 2020)
      Extracting copper is energy-intensive. At the same time, copper is a key material for building the energy systems of the future. Both facts call for clean copper production. The present work addresses the greenhouse gas ...
    • Rahmann, Claudia; Mayol, Carolina; Haas, Jannik (Elsevier Ltd, 2018)
      When large-scale photovoltaic power plants (PV-PPs) operate under partially-shaded conditions, their power output can be extremely fluctuating. This situation may compromise the energy balance of the electricity grid, which ...
    • Carpentier, Diego; Haas, Jannik; Olivares Alveal, Marcelo; Fuente Stranger, Alberto de la (MDPI AG, 2017)
      The hydrodynamics of many hydropower reservoirs are controlled by the operation of their power plant, but the associated water quality impact is often poorly understood. In particular, significant hydropeaking operations ...
    • Ortiz, Julian; Kracht, Willy; Pamparana Manns, Giovanni; Haas, Jannik (Springer, 2020)
      Integration of renewable energy into mining and processing operations is becoming necessary as part of a strategy towards sustainability in the minerals industry. A solar photovoltaic plant along with a battery energy ...
    • Moreno Leiva, Simón; Haas, Jannik; Junne, Tobias; Valencia, Felipe; Godin, Helene; Kracht Gajardo, Willy; Nowak, Wolfgang; Eltrop, Ludger (Elsevier, 2020)
      Renewable energy systems are now accepted to be mandatory for climate change mitigation. These systems require a higher material supply than conventional ones. Particularly, they require more copper. The production of this ...
    • Chudinzow, Dimitrij; Haas, Jannik; Díaz Ferrán, Gustavo; Moreno Leiva, Simón; Eltrop, Ludger (Elsevier, 2019)
      Bifacial photovoltaics (bifacial PV) offer higher energy yields as compared to monofacial PV. The development of appropriate models for simulating the energy yield of bifacial PV power plants is a major topic in both ...
    • Haas, Jannik; Palma Behnke, Rodrigo; Valencia, Felipe; Araya, Paz; Díaz Ferran, Gustavo; Telsnig, Thomas; Eltrop, Ludger; Díaz, Manuel; Puschel, Sebastián; Grandel, Matthias; Román Latorre, Roberto; Jiménez Estévez, Guillermo Andrés (Elsevier, 2018)
      The use of solar technologies should proliferate in Chile as half of the country has a solar irradiance (GHI) above 5 kWh/(m(2)d). Moreover, the Atacama Desert exhibits further advantageous conditions with 7 kWh/(m(2)d), ...
    • Moreno Leiva, Simón; Díaz Ferrán, Gustavo; Haas, Jannik; Telsnig, Thomas; Díaz Alvarado, Felipe Andrés; Palma Behnke, Rodrigo; Kracht Gajardo, Willy; Román Latorre, Roberto; Chudinzow, Dimitrij; Eltrop, Ludger (Elsevier, 2017)
      Solar energy technologies are a promising option to lower the greenhouse gas emissions of energy generation. Using solar technologies in energy-intensive industries located in arid climate zones is an attractive alternative ...
