Project Goals

VERBUND is in charge of WP 5 (development of hydrogen processing). In cooperation with the project partners Axiom and Vienna University of Technology, this involves the processing and conditioning of hydrogen for use by potential industrial customers. VERBUND is involved in five further work packages, which are mainly concerned with the engineering, construction and operation of the electrolysis plant, with the reliable supply of hydrogen to resource-intensive industries, as well as with the modelling of electricity generation and the modes of operation of the electrolysis. The development of a model for the implementation of seasonal storage in the future energy system deserves special mention.

"With the USS 2030 project, we are generating knowledge on the processing and conditioning of hydrogen from pore storage for use by potential industrial customers. And we are gaining new knowledge about seasonal storage in an energy system that is supplied 100% from renewable sources.", says Robert Paulnsteiner.
