Eco-Sim: A Parametric Tool to Evaluate the Environmental and Economic Feasibility of Decentralized Energy Systems

Jean-Louis Scartezzini, Dasaraden Mauree, Amarasinghage Tharindu Dasun Perera, Karni Siraganyan

Due to climate change and the need to decrease the carbon footprint of urban areas, there is an increasing pressure to integrate renewable energy and other components in urban energy systems. Most of the models or available tools do not provide both an eco ...

Machine Learning and Geographic Information Systems for large-scale mapping of renewable energy potential

Dan Assouline

A promising pathway to follow in order to reach sustainable development goals is an increased reliance on renewable sources of energy. The optimized use of these energy sources, however, requires the assessment of their potential supply, along with the dem ...

Aspects of the energy transition and their effects on power systems

Laurent Vincent Pagnier

Most European countries are committed to an energy transition which consists in the substitution of conventional CO2 emitting energy sources by new renewable energy sources (RES), in particular wind and solar power. As opposed to conventional energy source ...

Exergoeconomic optimization of a solar driven system with reverse osmosis desalination unit and phase change material thermal energy storages

Hossein Pourrahmani

The goal of the current article is to suggest a novel solar system to produce power, fresh water, and cooling. As solar energy is unavailable at nights, a novel thermal storage system (TES) based on phase change material (PCM) is used to store the required ...

SCCER-FURIES - Determination of the flexibilisation potential of the electricity demand. ReEL D114b

Lionel Benjamin Bloch, Jordan Holweger

The mismatch between household electricity consumption and solar energy production is a key issue for the fast deployment of this technology in a low-voltage grid. Namely, as high photovoltaic generation occurs during the day while the load remains low, th ...

Evaluating the need for energy storage to enhance autonomy of neighborhoods

Jean-Louis Scartezzini, Dasaraden Mauree, Amarasinghage Tharindu Dasun Perera, Karni Siraganyan

Energy storage is generally considered as a means to bridge a period between when/where energy is available and when/where it is in demand. Storage plays an important role by providing flexibility to energy systems, increasing the potential to accommodate ...

Comparison-Based Optical Assessment of Hyperboloid and Ellipsoid Reflectors in a Beam-Down Solar Tower System With Linear Fresnel Heliostats

Meng Lin

Beam-down concentrating solar tower (BCST) is known for its merits in easy installation and maintenance as well as lower convection heat loss of the central receiver (CR) when comparing to a traditional concentrated solar tower system. A point-line-couplin ...

Colored solar façades for buildings

Andreas Schueler, Jean-Christophe Hadorn, Nicolas Jolissaint

Solar energy is a prime way to reach net zero energy buildings. Addressing buildings’ energy needs is a priority because buildings are the largest demander of energy (followed by industry then transport). However, harvesting energy from solar farms, implie ...

Techno-economic modeling and optimization of solar-driven high-temperature electrolysis systems

Sophia Haussener, Meng Lin

We present a techno-economic analysis of solar-driven hightemperature electrolysis systems used for the production of hydrogen and synthesis gas. We consider different strategies for the incorporation of solar energy, distinguished by the use of differing ...
