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.

The project intends to assess electric storage with batteries, conversion to e-methane via electrolysis of water and methanation of H2 at a bus terminal to optimize the utilization of variably produced electricity from solar PV cells in a transport system with electric and gas vehicles.

The project intends to assess electric storage with batteries, conversion to e-methane via electrolysis of water and methanation of H2 at a bus terminal in order to optimize the utilization of variably produced electricity from solar PV cells in a transport system with electric and gas vehicles. Specific methods and models will be developed for techno-economic evaluations and climate impact assessment for optimization of different operational strategies. The tools are developed to be adaptable and used in other regions in different countries. The Uppsala Region and Uppsala Vatten in Sweden are “need owners” and academic partners from Switzerland and Sweden will be main performer of the work plan, thus including academia and public companies in the consortium. The project has the potential to increase the number of electric buses by 30%, and to allow an increase by 50% in CH4 production for transport sector, resulting in 25% less greenhouse gas emissions than the current scenario.
