Jean-François Molinari, Brice Tanguy Alphonse Lecampion, Guillaume Anciaux, Nicolas Richart, Emil Gallyamov
Underground CO2 storage represents the most viable Negative Emission Technology capable of significantly reducing atmospheric carbon dioxide levels. Ideal reservoirs for CO2 sequestration are thick highly-porous and highly-permeable formations ensuring a h ...
2023Redox dual-flow battery for combined electricity storage and hydrogen production
The energy transition towards a carbon-neutral and sustainable economy is one of the greatest challenges of the 21st century to combat global warming and pollution. The decarbonization process is affecting every sector of the economy (electricity, transpor ...
EPFL2022Swiss Potential for Hydropower Generation and Storage - Synthesis report
François Avellan, Pedro Filipe De Almeida Manso, Martin Schmid, Paolo Burlando, David Felix
Hydropower (HP) is the backbone of the Swiss electricity system providing around 60 % (36 TWh/a) of the total electricity generated on a yearly average. With the planned phase-out of nuclear power plants, HP and other Renewable Energy Sources (RES) will ne ...
ETH Zurich2021SCCER JA-RED - Report on the performance of the implemented solutions with guidelines for subsequent implementation - D1.2.4
Luc Girardin, Luise Middelhauve
The foreseen important increase of the penetration of distributed renewable energies technologies into the electricity distribution grid is expected to lead to some major challenges. On the one hand, a large and synchronous production could lead in certain ...
2021On The Efficiency Of Energy Storage Systems - The Influence Of The Exchanged Power And The Penalty Of The Auxiliaries
Storage is an important domain of the energy sector, with its traditional, classical solutions for smaller and larger amounts of energy. Energy storage has become of higher importance in relation with the development of alternative energy sources, leading ...
UNIV NIS2021Aqueous Redox Flow Batteries Enhanced by Solid Boosters
One of the main challenges for certain electricity production technologies (e.g. renewables) is the capability to supply energy according to the demand. It follows that storing energy is a possible solution to the inadequacy between production and demand. ...
EPFL2020Benefits of a Diversified Energy Mix for Islanded Systems
Christophe Ballif, Marine Dominique Cauz, Laure-Emmanuelle Perret Aebi, Lionel Benjamin Bloch, Christian Rod
Achieving energy self-sufficiency is a major challenge for remote areas, especially islands. Various technologies have recently been developed to exploit renewable resources in such areas in order to reduce dependency on fossil fuels. This work focuses on ...
2020Downside Up:Rethinking Parcel Position for Aerial Delivery
Dario Floreano, Przemyslaw Mariusz Kornatowski, William John Stewart, Mir Alikhan Bin Mohammad Feroskhan
The conventional approach to parcel placement in most delivery drone designs today is to place the parcel centrally beneath the drone's rotor plane. However, if the parcel is too large, this will result in an obstruction of the propeller slipstream, incurr ...
2020Potential increase in energy storage capacity in the Swiss Alps to support the massive development of renewables: Case study of the Grande Dixence hydropower scheme
Anton Schleiss, Pedro Filipe De Almeida Manso, Jérôme François Sylvain Dujardin, Blaise Monay
Only 42 % of the mean annual production of large hydropower plants in the Swiss Alps is stored in their reservoirs. Once the reservoirs are full at the end of the summer semester, plants are operated as run-on-the-river in order to avoid spilling. A signif ...
2019A Cogeneration System Based on Solid Oxide and Proton Exchange Membrane Fuel Cells With Hybrid Storage for Off-Grid Applications
François Maréchal, Ligang Wang, Francesco Baldi, Maria del Mar Perez Fortes
Solid oxide fuel cells (SOFC) have developed to a mature technology, able to achieve electrical efficiencies beyond 60%. This makes them particularly suitable for off-grid applications, where SOFCs can supply both electricity and heat at high efficiency. C ...
