Research project
Innosuisse Flagship Greenhub
The "GreenHub" project is one of a total of eight large-scale flagship projects of the Swiss Innovation Agency (Innosuisse). Together with 16 research partners, the consortium led by OST is pursuing a clear goal: the development of systemic and innovative approaches for the production, conversion and storage of renewable energy…
Research project
ENSURE - Preventing extreme situations in the local power grid with chemical reactors
The ENSURE project is investigating various extreme situations that may occur in local grids in the future and ways of avoiding them. The focus is on the expected peak loads and issues relating to grid stability. The aim is to analyse which flexibilities and requirements new sector coupling technologies such as Power-to-X and…
Research project
GISOptiTes – Potential assessment of large-scale seasonal thermal energy storage in Switzerland by means of GIS based energy modelling and optimization
In this project we will develop a methodology to increase the synergies between top-down and bottom-up energy optimization tools with the aim of assessing the potentials of large-scale seasonal thermal energy storage (TES) in Switzerland.
The top-down approach carried out with Energy Scope will be used to assess the transition…
Research project
DecenTGrids – Decentral Storages for Energy Management in Thermal Grids
Heat storages can assist in the rational dimensioning and operation of thermal networks. They can smooth out peak loads and eliminate the need for fossil-fuelled peak load boilers. Heat surpluses can be stored temporarily. Decentralised storage systems can relieve the load on individual sections of the grid or enable grid…
Research project
SwissSTES – Swiss Seasonal Thermal Energy Storage
Substituting fossil fuels with renewable energies will not be feasible without a notable expansion of seasonal energy storage. Seasonal thermal energy storages (STES) are expected to contribute significantly to this goal. The project SwissSTES systematically analyses STES potentials such as available and unused cavities, geothermal…
Research project
RE-WITCH – Heating and cooling for industry with renewables and waste heat valorisation
The overarching aim of RE-WITCH is to deliver cost-competitive, game-changing solutions in the field of sustainable industrial cooling and heating. To do so, RE-WITCH will demonstrate advanced thermally-driven industrial cooling technologies based on ADsorption and ABsorption processes driven by an optimized mix of low-grade waste…
Research project
Alience – Alpine PV Competence
As part of the so-called «Solarexpress» initiative, numerous large-scale photovoltaic systems were planned in the Alps. The harsh conditions in the mountains, the yet scarce knowledge and experience, and the tight deadlines pose challenges for building contractors, engineers and owners. The goal of this project was to support them…
Research project
EffPlusWW – Efficiency boost for hygienic perfect domestic hot water with heat pumps
Due to the necessary decarbonization of the heat supply, heat pumps are becoming increasingly important for domestic hot water preparation. However, the relatively high requirements for hot water preparation and distribution temperatures for hygiene reasons often cannot be met with current heat pump concepts without the additional…
Research project
SOLINDARITY – SOLar-driven INDustrial power And heat upgRaded with hIgh-temperature heaT pumps for enhanced integrated process efficiencY
The EU-funded SOLINDARITY project aims to transform the industrial landscape by introducing a solar-powered heat enhancement system. Targeting industrial processes with temperatures up to 280°C, SOLINDARITY integrates a range of innovative and highly efficient components, including thermal solar collectors, thermal energy storage,…
Research project
SolIceTES – Advanced energy management control for ice storage with photovoltaics for cooling applications
This project aims to develop an advanced energy management system based on model predictive control (MPC) to optimize the operation of so-called “SolIceTES” systems for space cooling applications. A SolIceTES system consists of an ice-on-coil ice storage coupled with photovoltaics and a compression chiller. Such a system allows for…
Research project
PowerSlide – Motorized and Energy Producing Sliding Shutter
The goal of the project is to develop motorized sliding shutters equipped with PV modules: PowerSlides – shutters that provide protection, shading, and electricity generation all in one product. An innovative modular system with fully integrated technology and a wide range of design options allows for the visual design of the…
Research project
EnFK-WW-Elektro – Basics for direct electric heating of domestic hot water
According to the model regulations of the cantons in the energy sector (MuKEn; as of 2018), the hot water in newly built residential buildings may no longer be heated 100 % directly by electricity. During the heating period, the drinking water must be heated or preheated with the heat generator for space heating, otherwise at least…
