Energy storage is a key challenge for the integration of renewable energies in future energy supply. Power-to-Gas, which transforms electricity in chemical energy carriers, is currently considered as the
only pathway to enable a sustainable, renewable energy provision with a large penetration of fluctuating renewables up to a seasonal timeframe. The project RENERG2 focuses on crucial key
aspects and challenges of a future Power-to-Gas chain, namely electrolysis, methanation, hydrogen/CNG blending and infrastructure, HCNG applications in mobility and decentralized combined heat and power. In addition overarching issues as market, economics and grid integration are studied by ZHAW to evaluate and assess different future scenarios.
