The perspective of plasma conversion within the Power-to-X initiative — •Ursel Fantz¹, Ante Hecimovic¹, and David Rauner² — ¹Max-Planck-Institut für Plasmaphysik, Boltzmannstr. 2, 85748 Garching — ²AG Experimentelle Plasmaphysik, Universität Augsburg, Universitätsstr. 1, 86159 Augsburg

The Power-to-X initiative refers to various technologies for storing or using surplus electricity of variable renewable energies such as solar energy, wind energy and hydropower to convert the power into gas, heat or liquids. Using plasma technology for conversion of low energy molecules into value-added chemicals (following the Power-to-Gas route) is a promising approach: plasmas provide a fast response time and high throughput, are tolerant against impurities and operate different gases in a wide parameter range. Various plasma reactor concepts for formation of syngas, hydrogen, and ammonia are presently under investigation at the technology readiness level of about three to four. Within the plasma activities embedded in the Research Field “Energy” of the Helmholtz Association an atmospheric plasma torch is investigated. Its goal is to established the plasma route and develop a prototype reactor. A near future milestone is the performance comparison of plasma CO₂ conversion into CO including the gas separation process with low temperature and high temperature electrolysis. These facets of the plasma technology and its perspective to contribute to the PtX route will be highlighted in the presentation.
