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 biomass resources are already largely exhausted. Energy carriers X, which are produced based on renewable electricity (Power-to-X), could replace fossil-fueled peak load coverage in the future.

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 into environmentally friendly liquid fuels using raw materials supplied, for example, by waste incineration plants.

Renewable Metal Fuels (ReMeF) are seasonal energy carriers which are able to enhance the energy security. We investigate the contribution that ReMeF can make as combined heat and power elements of the building stock a) to cover the local demand for electricity and heat and b) to feed electricity into the grid to support the energy system. In focus are metals as winter-energy suppliers based on their availability, cost, and chemical properties, which potentially can achieve greenhouse gas savings compared to import-options or natural gas based systems. PeakMetal is co-funded by the Swiss Federal Office of Energy (SFOE), and lasts from December 2022 to December 2023.

SPF has the technical lead in the EU Horizon Europe project reveal. Within this project, a seasonal energy storage cycle is developed that is based on the oxidation and reduction of aluminum as an energy carrier. The main responsibilities of SPF, besides the technical lead, is the development of technologies for Alu-to-Energy conversion: the conversion of energy that is stored chemically within the aluminium into heat and power. This development is in close collaboration with the institute UMTEC of OST. REVEAL is co-funded by the European Unions Horizon Europe Programme and Swiss State Secretariate for Education, Research and Innovation (SERI), and lasts from July 2022 to June 2026.
