The main goal of this Deliverable is to investigate factors that determine social acceptance of power-to-gas (PtG) technology in four involved in the STORE&GO project countries, namely Germany, Austria, Italy and Switzerland. In order to reach this goal, a survey of 500 households in each of the four countries was conducted. This survey included a choice experiment examining the preferences of European households with respect to PtG and alternative energy infrastructures. Further on, the survey also collected information on household knowledge and attitude with respect to renewable energy, as well as their current socio-demographic characteristics and their experiences with respect to their electricity provider and consumption issues (power outages, delays in bill payment, etc.).
