ReWAX – Smaller heat pump dimensioning by X-to-Energy for peak load coverage

By using a peak load auxiliary heating system, oversizing of the heat pump can be avoided. Oil and gas peak load boilers are standard today but should be replaced in the future due to their CO2 emissions and measures to fight climate change. The utilization of biomass as an energy source is comparatively more complex and domestic…

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…

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…

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…

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…

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…
