Conceived by Switzerland’s Ecole Polytechnique Fédérale de Lausanne, Clip-Air proposes a plane with a single flying wing encompassing the airframe, cockpit, and three engines, attached to a maximum of three interchangeable capsules a more flexible and effi ...
Similar to other renewable energy technologies, the development of a biogas infrastructure in the Netherlands is going through social, institutional and ecological evolution. To study this complex evolutionary process, we built a comprehensive agent-based ...
The direct transformation of sunlight into fuels and chemicals has attracted considerable attention for the potential impact on the storage of solar energies at large scales and the reduction of CO2 emissions. More than 80% of our current global energy con ...
Life cycle impact assessment indicators are integrated for studying the process integration of renewable resources and CO2 capture and storage (CCS) in power plants. Besides the expected reduction in global warming potential (GWP), CCS induces energy and c ...
An exergy and environmental comparison between the fuel production routes for Brazilian transportation sector, including fossil fuels (natural gas, oil-derived products and hydrogen), biofuels (ethanol and biodiesel) and electricity is performed, and the p ...
This paper presents an exergy and environmental assessment of a 1000 metric t/day ammonia production plant based on the steam methane reforming (SMR) process, including the syngas production, purification (CO2 capture) and compression units, as well as the ...
During continuous operation of energy systems, the performance of components will mostly, gradually deviate away from the reference conditions due to performance degradation, which may eventually lead to malfunctions or operation failure. The complex inter ...
This topic aims at understanding precisely what are the mobility behaviors and aspirations of people under 18. The increasing use of ICT enables a larger access to several information (vehicle availability, travel times, costs, etc.) and payment systems. D ...
Lactic acid (LA) is considered for the diversification and value addition to sugar industry in South Africa, through a bioconversion of sugarcane bagasse and leaves. A bioconversion process was modeled in Aspen Plus (R) V8.6 and its environmental impacts w ...
The design criteria for modern sustainable development of vehicle powertrain are the high energy efficiency of the conversion system, the competitive cost and the lowest possible environmental impacts. In this article a multi-objective optimization methodo ...
