The IET Institute of Energy Technology conducts research and development in the field of power-to-gas and power-to-X at their facility "HEPP" (High Efficiency Power-to-Methane Pilot).

The HEPP (High Efficiency Power-to-Gas Pilot) project will be carried out from 2017 to 2020 and realized by a sponsorship of research funding and industry. The research results flow into the European Union's Horizon 2020 research framework program in the Pentagon project, which involves a total of ten institutions from academic research and industry from five European countries.

With technical innovations, the experts at the IET Institute of Energy Technology want to increase the technology maturity of power-to-methane technology and demonstrate it on a small scale in a real environment. The innovations in this project relate to efficiency, so that the economic viability of the technology is increased and the environmental impact of the methane produced is reduced. Industrially relevant questions will be answered so that a transfer of the technology to a large-scale plant with an efficiency of 70% will be possible.

The core element in the HEPP project is a 10 kW demonstration plant, which is being built in Rapperswil. The concept of the plant includes a high-temperature electrolysis and an integrated heat management. In addition, the project integrates innovative technologies developed in Switzerland for the first time and investigates system behavior.

"The demonstration plant was inaugurated in the fall of 2018 and has since been shown to 1,200 visitors in guided tours. Current projects will run until mid-2021, and the IET's power-to-X activities will expand to other topics, with more projects being developed at the facility. We hope that guided tours will be possible again in 2021. Please send requests for guided tours to the following email address: besuch-ptx(at)ost.ch
