Methods and systems for energy-efficient communications interface

In a high-impedance communications interface, driver energy consumption is proportional to the number of signal transitions. For signals having three or more distinct levels, it is possible for a signal driver to salvage energy from some downward signal tr ...

The energy transition – an integrative analysis

Claudia Rebeca Binder Signer

The ongoing energy transition is seen as a key component for the transition towards a more sustainable society. An important component in the move towards a sustainable energy system is the transition from a mainly centralized, fossil-fuel system to a more ...

Simulation of energy recovery on water utility networks by a micro-turbine with counter-rotating runners

François Avellan, Elena Vagnoni, Cécile Münch-Alligné, Loïc Andolfatto, Vlad Hasmatuchi

Wherever relief valves and other energy dissipation devices are installed to limit the pressure, water utility networks provide unexploited hydropower potentials. This is mainly due to a lack of economically viable technologies for energy recovery in the p ...

Proof-of-concept for facile perovskite solar cell recycling

Fabrizio Giordano, Joachim Maier, Othmar Müntener, Ulf Anders Hagfeldt, Norman Pellet, Jeannette Medina Kadro

Perovskite solar cells based on CH3NH3PbI3 and related materials have reached impressive efficiencies that, on a lab scale, can compete with established solar cell technologies, at least in short-term observations. Despite frequently voiced concerns about ...

Geothermal Energy and Biomass Integration in Urban Systems: a Case Study

François Maréchal, Stefano Moret, Léda Gerber, Emanuela Peduzzi, Frédéric Louis-Pierre Raphaël Marie Amblard

Heating, electricity and transportation are the three components of urban systems final energy consumption. Geothermal energy and biomass are two promising renewable energy resources that can be used for the production of heat, electricity and biofuels, th ...

Energy Planning in the Urban Context: Challenges and Perspectives

François Maréchal, Sébastien Cajot

Cities are responsible for roughly two-thirds of global primary energy consumption, and are therefore expected to play an essential role in reaching European climate change targets. Innovative urban planning methods are in particular needed to benefit from ...

Environomic optimal design of power plants with CO2 capture

François Maréchal, Laurence Tock

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 ...

Experimental evaluation of the velocity profiles and performance of a counter rotating micro-turbine by 2D laser Doppler velocimetry

François Avellan, Elena Vagnoni, Cécile Münch-Alligné, Loïc Andolfatto

The most exploited renewable energy at a global scale is hydropower, which nowadays accounts for the 18 % of the world’s electricity supply. Its production is expected to increase approximately 3.1% each year in the next 25 years maintaining its share in t ...

Heavy hydrocarbon mixtures as fuels for SIEMENS DLE gas turbines

Associated gases at oil wells are often rich in heavy hydrocarbons (HHC, here denoting hydrocarbons heavier than methane). HHC may cause handling and combustion difficulties as their properties are different from standard natural gas, therefore HHC rich as ...

Sustainable Social Housing in Temperate Areas. Italy and Brazil: the use of vegetation as a retrofit strategy

Luisa Pastore

Contemporary cities are more than ever committed to tackle environmental challenges such as the attenuation of the urban heat island phenomenon and the renovation of a large building stock characterized by low indoor comfort levels and increasing energy co ...
