Low-carbon societies will need to store vast amounts of electricity to balance intermittent generation from wind and solar energy, for example, through frequency regulation. Here, we derive an analytical solution to the decision-making problem of storage o ...

Switzerland has a small but internationally recognised set of competences and actors in fuel cells and hydrogen, from fundamental research to technology and product development. Swiss organisations are prominent in a number of research partnerships, and some have either major international co-operation or are partly or fully owned by overseas companies. However, the sector in Switzerland remains somewhat fragmented, with many actors pursuing their own niches and relatively little cross-fertilisation or co-o

The introduction of hydrogen in transport, particularly using fuel cell vehicles, faces a number of technical and non-technical hurdles. However, their relative importance is unclear, as are the levels of concern accorded them within the expert community c ...

PSP (Pumped-storage power plants) represent the only mature option for large-scale electricity storage, and offer a wide range of grid management services, ranging from peak power production to ancillary services. This technology has undergone drastic prog ...

The transition from a fossil fuel base to a renewable energy system relies on materials and, in particular, metals to manufacture and maintain energy conversion technologies. Supply constraints shift from fossil fuels to mineral resources. We assess the av ...

This report provides an overview of the current debates about demand response development, focusing primarily on Europe, with some comparisons to the United States. ‘Demand response’ includes strategies that involve end-use customers adapting or altering their electricity demand in response to grid conditions or market prices. It is viewed as a multi-purpose power-system resource that enhances the energy system’s capacity to cope with increasing demand, rising costs of conventional transmission and distribu

In each season when the DA pulsating white dwarf G29–38 has been observed, its period spectrum appears very different, but it always contains a forest of harmonics and cross-frequencies. The ratio of the amplitude of these non-linear frequencies Ac to the product of the amplitudes of the corresponding parent modes A1A2 has been measured. The results are compared with the predictions given by three existing theoretical models. Our analysis shows that the non-linear frequencies present in the period spectrum

An analysis of the phase spectrum of the DA pulsating white dwarf G29–38 over many seasons has been performed. This complements a companion paper which analyses the evolution of the temporal spectrum of G29–38. We show that, with one exception, the relative phases of the harmonics and combination frequencies are all oscillating in phase with their parent modes. This not only suggests that these non-linear frequencies owe their presence to harmonic distortion and not to resonant mode coupling, but also ex

In light of the environmental consequences of linear production and consumption processes, the circular economy (CE) is gaining momentum as a concept and practice, promoting closed material cycles by focusing on multiple strategies from material recycling ...

Using an exergy based indicator is highly desirable to compare future national energy strategies. A new web- based information platform called energyscope.ch, informing the general public on the Swiss energy transition was presented at ECOS2016. This paper ...

The numbers of electric vehicles (EV) will increase as many countries perceive EVs as a solution to reduce the emissions of transportation and therefore incentivize their adoption. However, the deployment of public charging infrastructure is lagging behind ...

As a follow-up to IRGC's report on demand-side flexibility for energy transitions, this Policy Brief highlights that increasing flexibility in power systems is needed to accommodate higher shares of non-controllable and intermittent renewable generation, and that this requires changes to the market design and regulatory framework, to facilitate the development and deployment of appropriate technologies and market-based instruments (e.g. taxes and subsidies). The Policy Brief focuses on demand response (DR),

The transition towards decarbonized and efficient energy systems has broad socio-economic implications. We estimate the potential impacts on employment from efforts in energy efficiency in industry, transport and buildings as well as substituting local ren ...

Problem definition: Vehicle-to-grid increases the low utilization rate of privately owned electric vehicles by making their batteries available to electricity grids. We formulate a robust optimization problem that maximizes a vehicle owner’s expected profi ...

Zahlreiche Länder befinden sich heute in einem Prozess der Energiewende. Die Schweiz zeigt besonders grosse Ambitionen auf diesem Gebiet: schrittweise von der Kernenergie Abstand nehmen, die Abhängigkeit von fossilen Energieträgern verringern und die Treibhausgasemissionen reduzieren. Es existieren diverse Strategien um unser Energiesystem zu wandeln, was zu lebhaften, manchmal gar hitzigen und nicht immer gut informierten Debatten führt. Dieses Buch schlägt konzise, auf Tatsachen beruhende und verständlich

Microalgae have a significant potential to be a sustainable source of fuel and thus are of interest in the transition to a sustainable energy system, in particular for resource-dependent countries such as Switzerland. Independence of fossil fuels, consider ...

In this report the research team from the 2035 Urban Charging Research Project from the Swiss Federal Institute of Technology Lausanne (EPFL) presents a list of potential electric vehicle charging solution that could be implemented by 2035 in urban setting ...

La «transition énergétique» est au cœur des préoccupations politiques de nombreux pays. Dans ce contexte, la Suisse affiche des ambitions particulièrement élevées en la matière: renoncer progressivement à l’énergie nucléaire, diminuer sa dépendance aux énergies fossiles et réduire ses émissions de gaz à effet de serre, tout en cherchant à accroître son indépendance énergétique envers l’étranger. Diverses stratégies existent afin d’opérer la transformation de notre système énergétique, ce qui suscite des déb
