摘要

Power-to-Gas (PtG) is discussed as a key technology for sector coupling, as it transforms surplus renewable electricity into hydrogen or downstream gaseous energy carriers, thereby technically and commercially linking electricity, gas, and heat networks with the industrial and mobility sectors. This paper situates the role of PtG in the future Austrian energy system and examines the market relevance of various use cases. Both supply-driven concepts, which are oriented towards local renewable electricity generation, and demand-driven applications for meeting industrial hydrogen needs are analyzed. The European regulatory framework (RED II/III, delegated acts on RFNBOs, SAF requirements) defines the conditions under which PtG-based hydrogen is recognized as renewable, with additionality, temporal correlation, and geographic correlation being central requirements.

System studies show that the macroeconomic benefit of PtG is not primarily determined by the conversion efficiency of individual electrolysis units, but by the ability to relieve grid congestion, substitute CO2-intensive processes, and provide additional flexibility options. For Austria, a dual role emerges both as a transit and import country and as an operator of regional PtG hubs.

The paper derives from this the research, technology, and innovation needs, and identifies the development of multimodal business models, integrated system modelling, and scalable demonstration projects as key action areas for successful market development.
