Research project

Energy storage for sustainable regional development: Optimized integration of renewables in smart transport systems (Power-2-Transport)

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.

This project has been funded by partners of the ERA-Net Smart Energy Systems ( and Mission Innovation ( through the Joint Call 2019. As such, this project has received funding from the Swiss Federal Office of Energy under grant agreement Sl/502070-01, and European Union's Horizon 2020 research and innovation programme under grant agreement no. 646039 and 775970.

The Swedish participation in the ERA-Net Smart Energy Systems is funded by the Swedish Energy Agency. The Swiss part of the project is financially supported by the Swiss Federal Office of Energy (SFOE).
