ANDRITZ to Build Austria's Largest Green Hydrogen Plant

RAG Austria AG and international technology group ANDRITZ have initiated the construction of Austria's largest green hydrogen plant. The 12.5 megawatt (MW) facility is scheduled to begin operations by the end of 2026.

The plant is designed to convert surplus renewable electricity, primarily from solar power, into green hydrogen. This initiative is intended to enhance energy security by enabling the storage of energy generated during periods of high production, particularly in summer, for use during times of increased demand in winter. The facility will also supply domestically produced green hydrogen for industrial applications.

ANDRITZ is undertaking the project on an EPC (Engineering, Procurement, Construction) basis, encompassing project execution and commissioning. Once operational, the plant is expected to produce approximately 17 million cubic meters of green hydrogen annually, equivalent to over 1,500 tonnes per year.

The project addresses a key challenge in the energy transition: storing renewable energy when production exceeds demand and making it available later. By converting surplus solar power into hydrogen, RAG Austria aims to develop large-scale seasonal energy storage, supporting broader renewable energy objectives in Austria and Europe.
