Continuous production prototype for scaling up of graphene oxide/carbon nanotube composite synthesis towards efficient hydrogen storage

Andreas Züttel, Yudong Xue, Yunting Wang

A continuous production prototype for scaling up the synthesis of a graphene oxide/multi-walled carbon nanotubes (GO/MWCNTs) composite as a hydrogen storage material has been proposed in this study. This prototype consists of an automatic feeding and mixin ...

Probabilistic Techno-Economic Assessment of Medium-Scale Photoelectrochemical Fuel Generation Plants

Sophia Haussener, Alexandre Dominique M. Cattry

Photoelectrochemical (PEC) systems are promising approaches for sustainable fuel processing. PEC devices, like conventional photovoltaic-electrolyzer (PV-EC) systems, utilize solar energy for splitting water into hydrogen and oxygen. Contrary to PV-EC syst ...

Influence of convection on the thermal storage performance of energy tunnels

Lyesse Laloui

The decarbonization of the built environment requires rapid growth in energy storage solutions due to the intermittent nature of most renewable energy sources. This paper focuses on the efficacy of so-called energy tunnels (i.e., tunnels equipped with pipe ...

Proof-of-Principle Positron Source for Future Colliders

Nicolas Vallis

The PSI Positron Production experiment, known as P3 or P-cubed, is a proof-of-principle positron source and capture system that can greatly improve the state-of-the-art positron yield. The P3 project is led by the Paul Scherrer Institute (PSI) under the au ...

Efficiency of dynamos from an autonomous generation of chiral asymmetry

Salim Bennouna

At high energies, the dynamics of a plasma with charged fermions can be described in terms of chiral magnetohydrodynamics. Using direct numerical simulations, we demonstrate that chiral magnetic waves (CMWs) can produce a chiral asymmetry μ5=μL-μR from a s ...

Precious metal-free (photo)electrochemistry for green hydrogen production

Hannah Elizabeth Johnson

Climate change caused by anthropogenic greenhouse gas emissions necessitates a transition from fossil resources to greener fuels and chemicals. Hydrogen is a promising green energy vector due to its high gravimetric energy density, its potential use in fue ...

Future Swiss Energy Economy: The Challenge of Storing Renewable Energy

Paul Joseph Dyson, Andreas Züttel, Noris André Gallandat

Fossil fuels and materials on Earth are a finite resource and the disposal of waste into the air, on land, and into water has an impact on our environment on a global level. Using Switzerland as an example, the energy demand and the technical challenges, a ...

Decentralized ICT integration in residential buildings

François Maréchal, Dorsan Alexis A. Lepour

To answer the growing demand for data computing, data storage and data transmission, the current trend is to construct centralized hyperscale data centers, whose power usage effectiveness (PUE) has substantially improved in recent years. Still, the operati ...

Energy integration of CO2 networks and Power to Gas for emerging energy autonomous cities in Europe

François Maréchal, Luc Girardin, Raluca-Ancuta Suciu

The concept of urban CO2 networks has been developed to deploy heat pump based district heating and cooling systems in dense urban areas. The use of the CO2 phase change reduces the cost of the heat distribution while allowing to recover waste heat that is ...

Anomaly driven signatures of new invisible physics at the Large Hadron Collider

Alexey Boyarsky, Oleg Ruchayskiy

Many extensions of the Standard Model (SM) predict new neutral vector bosons at energies accessible by the Large Hadron Collider (LHC). We study an extension of the SM with new chiral fermions subject to non-trivial anomaly cancellations. If the new fermio ...
