Since 2011, the engineering firm Ludwig-Bölkow-Systemtechnik (LBST) has been following the development of relevant PtX activities and maintaining a database, which currently contains 900 projects from around the world. While initially only smaller systems with electrolysis capacities in the kilowatt range for research purposes were listed, more recently projects with electrical outputs of several megawatts have been realized. Even larger plants in the gigawatt range are currently in various stages of preparation for various countries. Drivers of this are the rising pressure to reduce greenhouse gas emissions, the extensive public as well as private funding, and not least the Ukraine conflict, which has accelerated the need to diversify the energy supply.

From April 2022, in Germany alone are located around 200 research and demonstration units in various stages of implementation, from “announcement” to “planning,” to “construction and operation.” The total installed output capacity of PtX stations in the Federal Republic currently amounts to nearly 55 MW. For comparison, in May 2012, the total capacity lay under 50 kW. This corresponds to a thousandfold increase within ten years.
